Digital negatives have become an important part in the workflow of a lot of alternative process printers.
One can print images using both analog as well as digital images.
I think it has done a lot to resurrect the interest in the alternative processes.
So, what about a thread dedicated to alt-process prints using digital negatives or positives from non-large format images?
Platinum, Palladium, Cyanotypes, Kallitypes, Carbon, Gum, Photogravures etc. They are all welcome.
Post them!
I'll kick things off with one of my own:

I believe this image, and this thread belong somewhere other than the Large Format Forum. A digitally captured image is not large format.

That is why it is in the "Lounge", where non-large format stuff are relegated.

With the excellent Large Format shooters across the world who now use various camera sizes and make digital negatives, why not?
Using and scanning from larger negatives is fine but many of the old line photographers are getting along in years and lighter equipment makes sense.

Add in we are seeing more freedom in what and how people photograph using smaller sized cameras and we are seeing new and even more exciting images from many.

Now that I've started to take some steps in cyanotype territory myself, I start to appreciate this image even more; excellent tones and contrast! The composition suits the process very well too.

Here's a cyanotype from a digital negative from my end. The original was shot with a Mamiya 50mm/1.7 on Fomapan 100. Printed on double coated Schut drawing paper (DIN A5 size, the image itself is a little over 10x15cm). I spent quite some time calibrating to control the high contrast and exponential exposure curve of this process. This is the first print I'm sort of happy with. The 'sort of' stems from some issues with negative flatness, so the next step will be to devise a more reliable printing frame.

Great images!
I love to mess with cyanotypes.I had tested a lot of papers and finally set at Canson Montval ( pretty inexpensive) pre acidified in a bath of Sulfamic Acid to neutralize the calcium carbonate. It goes very well for me with the New Cyanotype formula and setting the gamma to 2,2 ( Dr. Mike Ware method) to get an overall "curve" to correct the tones. Works better to me then Chart Throb. The other thing is that I got an Epson 1430W printer that, against all odds, blocks UV big time with Claria Inks giving me white paper whites, or almost:
125139
This is a somewhat crappy repro. The real thing is much bluer and better looking...

koraks
18-Nov-2014, 06:11
Thanks Ricardo! I have no experience with ChartThrob, but it looks interesting. However, I had a lot of fun creating a curve by hand (and by eye) for cyanotypes and for my purposes, it works quite well. I use an Epson 3880 and I find that the photo black and yellow inks block UV great - so much in fact that I have to print with a lower color density (-18%) on the transparencies I use. I outlined the process I use on this page (http://koraks.nl/index.php?menuparent=&page=11).

Gorgeous tonality on that cabbage print btw!

Some more from Metz, France; these were made with a Canon 7D, so they're very much from a digital origin.

Hendrik, i had to stop using ferric chloride in my little studio. There is just not enough space. Besides, the sink near where I can work is made of aluminum. I hope to get another space where I can do gravure without etching everything in sight. I hope to be able to use rosin and asphaltum. Till then, i have to make do with photopolymer plates.

I mentioned elsewhere on the forum that I have fallen into the hole of carbon printing as well. About two weeks after starting with this endeavor, I am capable of producing prints that are sort of passable. I use digital negatives because this approach gives me more freedom in terms of image size, as well as more consistency in my approach. For your entertainment, inspiration or critique, I'll share my process parameters:

Digital negatives:
Epson 3880 with Jon Cone's ConeColor Pro inkset (not ideal for digital negatives, but I like to use one printer for all my printing purposes)
Color density +50
Advanced B&W mode; yellow +75, photo black
Esselte 57161 A4-sized inkjet transparencies
Front feed to prevent pizza wheels (works like a treat too!)
I use a 3mm printed safe edge.

Glop recipe (amounts indicated per liter; I generally mix 150ml - 400ml):
Gelatin 250 bloom - 100g
Sugar - 100g (low humidity here in this time of year; heavy curling)
Pigment is Amsterdam brand lamp black acrylic paint - 160g (yes, that much! I found it the only way to get sufficient contrast in the prints from the weak digital negatives I make)
No other additives. Haven't tried adding glycerin to deal with the curling, but I found that using more sugar and storing the tissue flat under a pile of books helps enough with that.
I pour to a height of 0.5-1mm on cheap 200g/sqm A5 size sketching paper, ca. 20ml for a 17x13cm size (6.8" x 5.2"); drying time is ca. 36 hours.
I found that 'pouring' goes particularly well using a large 80ml syringe with a long, blunt needle (no coincidence these are the exact items that are shipped with the ConeColor Pro ink set...). Easy dosage, virtually no bubbles, very even thickness.

Sensitizing:
Spirit sensitizer, 6% ammoniumbichromate in water, diluted with acetone to 0.75% to 2% working solution, 4ml per print for the indicated size (= 30mg to 80mg ammoniumbichromate per print)
Brushed on with a 1" soft brush or a 3" foam brush; I see little difference in terms of application with particularly weaker dilutions being prone to brush marks regardless of the brush used.
I tried diluting with denatured alcohol, which worked fine (no fogging or other unwanted chemical interactions), but dried *much* slower than acetone.

Exposure:
Philips face tanning unit HB172 with 4x15W fluorescent tanning tubes.
Distance between light source and tissue on exposure is 30cm (12"). This prevents the tissue from heating up and getting sticky. I could probably get away with 15cm/6", but tolerances on exposure would be smaller as well.
As a printing frame, I use a cheap photo frame. I place a kitchen towel under the tissue in order to keep it flat; I found this helps tremendously in getting good contact between the tissue and the negative.
Exposure times vary between 6m50s to 7m30s, depending on desired contrast, dmax, etc. Most of the contrast control is done by varying the sensitizer concentration.

Transfer and development:
I transfer to Schut A5 sized 160g/sqm sketching paper, which I also use for cyanotypes. I size it three times with a 3% gelatin + ca. 1% chrome alum solution.
I noticed no differences in the transfer process or success rate with transfer water temperatures varying from ca. 16C to 30C (ca. 60F - 85F).
I let the tissue-paper sandwich rest for ca. 30 minutes under the pressure of a couple of books.
'Development' is done in water of 40C - 70C (ca. 105 - 160F); again, I noticed no real differences other than hotter water works a bit faster (but not very much) and is obviously harder on the paper.
After development is complete, I gently scrape away the unwanted borders of tissue outside the image area and rinse briefly in cold, running water. Hang to dry.

I'll probably make changes as I continue experimentation, but I find that the method described above works pretty well at this point for me. YMMV.

Digital snapshot of my girlfriend (EOS7D with 35/2IS); slightly overexposed during printing (visible in the safe edge). 0.75% sensitizer, 7m30s.
http://www.koraks.nl/galleries/prints/CPT_141_E.jpg
Some bubbles and pigment clumps due to errors during transfer and hot water development (scratched the unwanted tissue from the edges in the hot water bath; not a good idea, it turned out).

Photo from a shoot with a friend's band a couple of years ago (EOS20D with 24-70L; no longer in my possession due to theft...). 1.75% sensitizer, ca. 7m

You may or may not like the pretty extensive dodging and burning in digital post processing; either way, they have little to do with the printing process. Just so you know.

Thanks! I very much enjoy yours, thet must look stunning in real life. Yes indeed, even without a properly optimized curve, the results are really satisfying; obviously I'm biased since I put all the work in them, but you know how it is ;)

Funny thing about the process being difficult: I was reading a book from the early 1940s bout portrait photography and the final chapter discussed carbon prints. The author stated that any serious amateur should print his best photos as carban transfers due to their beauty, and he proceeded to explain that it makes sense as well from a practical viewpoint since the process is pretty easy. The art of inkjet printing was evidently still very far into the future.

Thanks Sandy - we are starting to make progress- by this time next year maybe will have done 1/2 of the 10000 prints needed to get a great handle on the process.

Sandy- you notice the stosser system is working well... and NO you cannot have it back.

Is Paulette using the Stosser system for cyanotype over platinum? Sam's work looks very sharp and he is doing basic manual registration with his two-color negatives.

Sandy

bob carnie
5-Jul-2015, 06:25
Yes she will be using Stosser and aluminum registration.. but I can understand why Sam's look sharp as both negatives basically blend into each other , I imagine one of the images is more dominant and provides
the sharpness, and the other fills in the blanks. He also could be sharpening the dominant image like we do to provide a more convincing look. Also he probably has his sizing method
nailed.
I will encourage her to try some different sized papers and see if she can make it work without punch method.

We are only sharpening the palladium negative in our work, the three colours are not sharpened, funny it almost works as if the image is more sharp this way.
The last project we worked on was a series of prints from the original I Phone. I thought the prints would be less than crisp, I was totally blown away with the overall sharpness. We were maginifying
the images to 10 x10 inch. There is one which I am keeping as a printer proof which is two little children walking into an adobe type building in Afganastan which is IMO one of the nicest images I have
ever printed.. talk about a concept- IPhone- Afganastan- Children- combined with a process that mixes two Century's of technology and process.

If you think about the concept of un-sharp masking its the close butting up of a sharp area(tone) to a soft area(tone) to create the illusion- this is all making sense to me now.
Gangler and Bently are laying down three layers to Melemix ( which will not shrink)then transfer as a complete package to a receiving paper so they have figured out their way of keeping it all registered.

We tried Johns melimex with a total disaster - the curl post process was impossible to deal with. Using this aluminum is very slick and easy. We are now going to try over the next few months a releasable
mount material which will then allows the paper to be off the aluminum. But I must say once on aluminum the final presentation matted and framed is quite lovely.

I am hoping this system of registration transfers well as I move up to larger prints. I know the positioning of the punch hole registration will be on the long side of the image and as well as close as I can
get to critical image area. We are going to move to the big exposing system in the new year. We have been keeping the non image area active so far so we can see the accumulation
of our work in the rebate area and also see the registration tabs. Will eventually tire of this cool look and clean up rebate with a ruby mask on top.


There are lots of variables. One that has proven to be a life saver is keeping the rooms at around 45% humidity. The winter months will require a few more humidifiers downstairs to make this
all happen.

Yes- the 25gage aluminum sucked the rubber blanket inwards and we had to adjust the blanket , I have never seen this with the Nuark with photocomp.
I guess we could lower the pressure but going to the thinner gage aluminum gives no problem and also is lighter for final presentation.

this image courtesy Bob Carnie (yours truly) - this is part of my ongoing solarization project and is where all the last years of madness is leading too.

Bob,

If you ever get a unit like the NuArc "Starlight" you would not have this kind of issue. This unit, which is designed primarily for the screen printing industry, uses a flexible neoprene blanket and it will actually create a vacuum drawing down over the large screens used in that industry. I am printing at this time with a poor man's version of this concept, the X-Vactor, produced and sold by Ryonet. I have done a fair amount of customizing to my unit, installing a light integrator sensor, and running the unit through an Olix light integrator. The X-Vactor is a bit underpowered IMO so I am supplementing the existing 36" long BL T8 tubes with 2400 of the 5050 LEDs with output in the 395-405 range. This will give a total of some 800 watts of low temperature UV radiation and I am expecting that printing times will be about 1/4 what they are with the 1000 watt HID platemakers.

On the immediate agenda here are carbon transfer prints 24X36" in size, from digital negatives of course. Somewhere down the line I may try some palladium over cyanotype with two-color separations.

What is your position on cyanotype longevity as compared to lets say a good blue transparent pigment??

I believe Cyanotype is very permanent. My understanding is that it can loose some of its denisty and color in alkaline conditions, but that conditions of acidity will bring the print back to life.

It has been quite a challenge getting all the pieces together that will allow me to make carbon transfer prints of this size. And lots of the pleasure for me in printing is figuring out how to do something. The end product is definitely important, but the process is what keeps me going. In any event, I have an image in mind for the first big boy, and will keep you posted when it comes out!!

Sorry for my late response.

7gr on 500 ml is a thin solution normal they say for normal sizing twice the amount gelatin.

And yes chrome alum.

I have tried it with unmixed and light sized kallitype. The sized one seemed a slight more dmax and a slight darker to black color. With de receipt from sevens book.

100 MG sodium acetate (the cheap food grade)
3gr tartaric acid
2ml 2% dichromate (pot / amm)
1 liter (distilled) water. (I use normal water) in Holland the water quality is very good and pure.

Andrew O'Neill
19-Aug-2015, 05:23
When you say you sized with gum, do you mean gum arabic?

ndg
19-Aug-2015, 06:11
I mix gum arabic powder and water at a ratio of 1:2. So 100 gm of gum in 200 cc of water. I leave the mixture in the fridge a few days to totally mix and dissolve. I don't add any preservatives and haven't needed to.
To size, I mix the gum with ammonium dichromate at a ratio of 2 of gum to one of dichromate.
I coat using a foam brush and dry in the dark room. Once dry, I zap it in my UV printer. I expose for the average time I need for gum prints. In my case, about 7 min. Then I clear the paper in water, solutions of sodium metabisulfite and water again.
Most times, one coat of size has sufficed. Occasionally, I've had to do a second coat.

pdh
19-Aug-2015, 06:49
Ah perhaps we have a difference in terminology.

I would regard a size as consisting only of a solution to modify the absorbancy of the paper, whereas gum+dichromate I would consider as forming part of a sensitising coating

Maybe I wasn't clear enough. Did you read my process completely? I coat my WC paper with the gum+bichromate mix, dry it and expose the sized paper (no negative) in my uv printer. This hardens the gum so it can act as a layer of sizing and modify the absorbancy of the paper! So far no negative! I then wash out the dichromate leaving me a WC paper with gum sizing! When this piece of gum-sized WC paper is dry, I sensitize with my pd-feox solution!

There are 2 alt process threads. The other one is for prints using LF in-camera negs. So unless you want to start a separate thread on using small format in-camera negs for alt-process work, I'll say, post them right here!

Sorry my ignorance but what's DR5...

cuypers1807
9-Sep-2015, 11:30
Thank you both! DR5 is a reversal process that makes B&W negative film into positive slide film. DR5 unfortunately had to move as their building was sold and they have not yet started offering the service again. You can also use color slide film to make tintypes but I prefer the B&W. It gives me more control over the tones as there is no color bias normally found with the wet plate process. RPX25 is especially nice as it has extremely fine grain that is suitable for enlargement.

Yes, I use an enlarger.
Another great feature of shooting the B&W over color is the ability to have clouds in the sky. The usual blue sensitivity makes that impossible.
Also there is no way I could have carried all my gear up there for this shot. Also 645 positive to 8x10 plate.

Very cool! Would you display this with a backlight, or put a backing on the plate? Did you make the emulsion yourself or was it commercial liquid?

Very cool! Would you display this with a backlight, or put a backing on the plate? Did you make the emulsion yourself or was it commercial liquid?

The two images here are tintypes on aluminum so no backing or lighting is necessary. I have also made ambrotypes from positives though and they would require a black background for proper viewing.
I am printing these essentially like a silver gelatin print.
The differences are that the original is a positive instead of a negative and the exposure times are much longer.
Exposure times can be as fast as 30 seconds and as long as 5 min depending on the age of the chemicals, size of film/enlargement, and density of positive. (cold head enlargers will be faster due to the fluorescent light source)
The two plates I posted today were made with Old Workhorse Collodion. I use Ilford Rapid Fix for a fixer instead of potassium cyanide.
As contrast filters will not work, I use different age collodions/exposure times to control the contrast of the plate.
I figured most of what I know through trial and error. I have a pretty good work flow now, so I am getting clean plates most of the time.

The only time I get this with my 3880 is when I have clogged nozzles. Run a nozzle check to see if this is the case; it really looks like clogged nozzles or a head alignment issue. With transparencies, it can be a problem if the head passes too low over the pictorico. The thing with transparency film is that the ink tends to lay on top of it instead of soaking into the medium (as with inkjet paper), so the head needs to have a bit more clearance than with paper. Otherwise the head will touch the deposited ink, resulting in clogged nozzles.

I had the opportunity recently to attend my first Platinum/Palladium printing workshop with a good friend. It was a wonderful experience to craft these prints with mine own hands using this alternative process. It was also great to be back in a real darkroom again. Albeit, you don't need to turn the lights out.

This is one of my platinum prints. Please be advised that this scan doesn't due the platinum/palladium process justice because; 1) I have a very mediocre scanner; and 2) I'm still learning, so my print is not as good as it could be. Properly done, platinum and palladium prints are absolutely magical and have a beautiful glow and subtle tonality. Until you see one of these prints in person, you can't really appreciate their unique qualities. The also have nearly unlimited permanence. It was a terrific experience I hope to pursue going forward.

Here is a question about what is a good replacement Epson photo printer for digital negatives. I searched the group for posts on this topic and couldn't find any information. My Epson R2400 (purchased in 2006) is still ok but I expect it to give up the ghost in the next year or so. Works well with Pictorico OHP. It is my understanding that the current similar replacement model (i.e. 13 inch prints) is the Epson P600. Ted Forbes has a YouTube channel called "The Art of Photography" and he does weekly videos on various photo topics. His most recent is a review of the Epson P600. In that video he claims that the P600 does NOT print film such as Pictorico. Does anyone have more insight on this. The big question obviously is what decent new 13 inch Epson printer does one get to make digital negatives with, aside from buying used or a non current model (e.g. the R3000) which likely will soon be out of stock.

27-Nov-2015, 13:35
I read somewhere, most likely on Jon Cone website that many latest Epson's will not allow refilled carts and has an unbeatable lockout.

He also said the P600 was not in that lockout group and he can hack the system with better and far cheaper digital neg inks.

You should run a nozzle check. Run a head cleaning cycle. A head alignment cycle wouldn't hurt either.

curious why Randy. I know a number of professionals who have switched to Canon the last few years and love them.

I bought a B&H Canon PRO 1 early edition and had problems with not enough usage and having to replace all 12 inks way too often for my output. Even printing only monotone B&W it requires and drinks all 12 inks despite having 5 for B&W. No way to set the darn device to use only B&W ink. Insidious bean counters.

Then I bought a last full set of ink, $500 and bingo it demanded an online firmware upgrade but I could not do a firmware upgrade with up to date iOS or Win 8. Calling for service revealed Canon only has a far suburban service facility and they told me I must bring the 70 lb monster to them. Out of warranty and cash repair.

I don't have a car, i dislike renting one to drive to the burbs and I needed 2 people to carry it for me. I am still pissed. Obviously...

I gave it away in the FS section here and I never heard if the second owner got it working.

I paid $1000 for it, put about $2K in ink in it and I have 2 prints I like from it on my wall. $1500 prints!

I was ignorant when I bought and didn't yet know that the Cone system and Epson was the only practical way to make B&W prints and digital negs. My 2 Canon B&W keeper prints are really nice, but my digital negs never went anywhere.

Early on I contacted Jon Cone about making a Piezo set for the Canon and he declined. Smart guy!

I have bought and successfully used many Epson photo printers, not perfect but they never needed an ambulance ride.

I believe this image, and this thread belong somewhere other than the Large Format Forum. A digitally captured image is not large format.

Some use LF cameras, scan the negative and make an enlarged digital negative so they can print much larger without having to deal with a much larger camera - for a variety of reasons.

The size and weight difference in carrying a 4x5 compared to a 12x20 outfit are major. Digital negatives make larger final contact prints a viable process.

Eric, thanks for the response.

For others, here is further information that I learned in connection to my question about the Epson P600 printer. It is useful to know. This was the reply I got on another discussion forum that deals with digital negatives. "A lot of the printers use optical paper sensors that see thru the film and will not load it. The fix it to tape a 5" piece of white paper along the loading edge of the paper".

Erik Larsen
28-Nov-2015, 16:53
I've not had a problem loading pictorico. I use the premium lustre photo paper setting in the printer dialog settings if that makes a difference. I don't think there is a pictorico film option to use? I am not an advanced digital negative printer so I'm not familiar with the potential pitfalls the p600 might cause, just that I haven't experienced any so far.

Both shot in Morocco earlier this month on 35mm, the first on Ektar 100 (the harem of a 17th century riad in Meknes) and the second on TMY2 (in the medina of Fez). Digital photos of actual prints. Image size is 10x15cm, print size 16x24cm. Paper is Schut Simili Japon 225gsm, Charbonnel black etching ink. DK3 photopolymer exposed using my trusty face tanner.

Attempting something I'm a novice at, inspired to give it a try by seeing some of the wonderful results that Bob Carnie has shown here. This is a gum over platinum/palladium. CMY as well as a pt/pd negatives used. The colors are no where near the original colors, but is has somewhat real but not really look to it[emoji3] It was an interesting experiment for me. 8x10 print on platine.

To Eriks comments above.. and his image -


I strive for a colour balance that is complimentary to the project I am working on. I am not fixated on real colour as I have been making TRUE colour images for over 40 years now and frankly I am bored with this reality.

I was lucky to enough to see some Fresson's years back and original Stephen Livik Tri Colour Gums. These influenced me greatly to want to do this type of work. In all cases with this type of work I think the printers role is to make the images believable, but still evoking a impression.
I think if we were lucky enough to see a bunch of tri colour gums of Keith Taylor we would immediately be able to understand that though a inkjet of the same images would be more true to reality , Keith's images are an interpretation that allows the viewer to fill in all the gaps. The beauty is knowing the images are permanent and hand crafted by an exceptional collaboration of artist and printer.

What I am getting at is we accept the dramatic shift from reality with black and white, to the point the black and white image looks real to us. I think over time as more people see these types of colour applications being shown here our style of prints may indeed become vogue.

I am very excited to be doing this at this time, as everything I have worked for is coming together in this new work... I applaud everyone here striving in hand made prints.

Thanks Bob. Do you use a red, blue and yellow pigment or do you wing it according to the image and use any color you feel works for the image? In other words, do you make a straight cmy and pt/pd print then add other colors on top of that? Just curious.

bob carnie
10-Mar-2016, 11:00
I do both :
I use Blue pigment green shade for Cyan, Magenta Pigment and Yellow with the cmy negatives

On personal work that starts with a BW image and tonal sep negatives I play a lot with other colours.. to try to obtain a pleasing look.
Step one is to do a bw conversion to lighten main colour elements in the image, ie I want them to print lighter than normal in the pt pd . This allows more
of the secondary colours to print in and shine.


I am going to do a test this summer where I separate into Red Green Blue negatives and use Red Green and Blue pigment - in direct comparison to doing a CMY negative and then trying to make a good Cyan, Yellow and Magenta.

lots to try but if I want a full colour I try to use CMY over pt pd

If I want to play I use anything... tried Opaque, tried Iridescent (not good for me) pigments. A Opaque pigment with a shadow only negative does work to increase dmax.

I am also playing around with digital negatives, and different loads of pigment to gum, to dicromate, which is laborious but needed.

Thanks for the explanation Bob, it makes sense. I hadn't tried lightening the first pt/pd print but your reasons for doing so seem reasonable. So many variables to consider that it is truly hours and hours of experiments to digest them all.
Here's another not true to to life look at a dilapidated shack in Cisco Utah light painted many years ago. It was a good candidate to appreciate the amount of each pigment to apply and their affect on the final image. 8x10 print on platine. Pt/pd and cmy negatives used.

very interesting, the colour seems to really blend well, I take it you are using registration.... what humidity level, and how long between each coat are you waiting?

I am doing a bunch next two weeks and will post some new ones after that.

Looking forward to what you show next Bob. Registration is dry mounted on hole punched aluminum. Humidity is probably in the 15-20% range here. I dry with a hair dryer and can coat and print in around five minutes. I've never considered the dry time as another variable to watch, I'm not consistent in my drying time at all really.

bob carnie
10-Mar-2016, 14:47
Wow that is a fast time, That would mean you could conceivably do the pt pd in morning and three coats in the afternoon. Are you force drying between layers and also are you using a sizing agent of any kind after the pt pd.

I think the low humidity is going to be a problem for you if you let your paper dry for much longer periods as I have seen huge problems with paper shrinking even on aluminum.

Last month it dropped to -20degree here with very low humidity and I made the mistake of coating large quantity's of one colour and printing one day and letting dry overnight then next day concentrate on the
next colour. Big f....ing mistake as the paper basically dried out and cause miss registration... Now I have really pumped up the humidity to around 45% . I am going to give a faster dry time though in humid conditions and see if I can complete more full images in one day rather than the assembly line application I tried before. We get great humidity 6 months of the year and right now it sucks.

Humidity never gets high out here in the desert. I can do a full 4 color print in about three hours if I force dry between coats(either hair dryer or hang to dry with a fan blowing). Most of that time is waiting for the gum portion to develop out. You're in a pickle compared to me as I don't have to worry about multiple images for clients and getting an assembly line set up. It's a different mindset for sure. I size with pva after the pt/pd print which dries very fast. I've been happy with the registration so far, but I haven't done any large print in 4 color yet so I maybe am just lucky so far.

Erik, I'm witnessing your initial steps into 3-color bichromates with amazement and I have to admit considerable jealousy! I think these images are pretty stunning. I didn't even come close to that when I gave gum printing a go and I gave up on it entirely.

bob carnie
11-Mar-2016, 07:09
Koraks - don't give up its a wonderful process - I downloaded Stephen Livik notes and they are very excellent, along with Christina Anderson book you can find your way.

It seems Erik and I are working in very different conditions and as you can see both of us are getting somewhere with this process. The more testers and workers out there the better IMO.

I am beginning to think you are on to something, by not allowing the process to sit overnight you are effectively avoiding paper shrinkage to start .. maybe it is not a immediate shrinkage but one over hours to take effect.

Thanks for the encouragement Bob, maybe I'll give it another go. I ran into many many problems in my trials. Development wouldn't work without brushing and that always caused very coarse images with ruined highlights; unassisted development basically got me nowhere even if I left the prints in the water for hours. Less exposure didn't help; it just made for a very brittle emulsion that still wouldn't develop properly and would brush away entirely if I tried that route. Registration was another issue, as was paper shrinkage. I always force dried with a hair dryer, so maybe the heat was just too much for the paper to deal with. Gesso sizing seemed to help a bit with development, but would make the image even more coarse and the highlights lift off to a greater extent. I never managed to get more than 2 layers on top of each other without the older layers sustaining damage later on in the process. Matching the negative to the emulsion proved difficult as well and neither silver nor digital negatives gave me usable results. There were so many problems that I didn't manage to make a single decent print. Another one was dmax, but I didn't try printing e.g. a base layer with van dyke or another process to augment density, so maybe that's a viable route. And the registration system I improvised with thumb tacks and tape just didn't work reliably either, so that's something I'd also need to reinvent to work for me. And I'm not even talking about measuring pigment concentrations consistently enough for reproducible results. Ah, it was a much deeper hole than any of the other processes I've tried so far, including polymer and carbon transfer!

Tri color gum over pt/pd. Probably could use another blue hit as the original is greener in appearance, but I kinda like it. My nephew on the little pigeon river in Tennessee.
8x10 on platine.

Gumoil print. Finally getting the hang of it. Realizing that only certain images can be printed effectively with this process. Original was captured on HP5 8x10.

So I just bought 20 sheets of Arches Platine. it says new improved.

I have been using it and it is good, but for some really stupid reason they package a big stupid f… king price sticker right smack dab over the arches indentation.. when you peel it off it rips away some surface and it
shows in the print.

I am cutting the paper into 4 equal 11 x15 sheets for this project and 25% of the sheets are NFG. I would like to kick the genius in the balls that decided putting a price sticker on the good side was a great idea.

I had the same experience, but I bought some from a local art store that was going out of business. 40 sheets for 1/2 price!
That stupid little bar code sticker could have been put on the back side don't you think? The coating looked different on the stickered part but it seemed to not affect the final print as far as I can tell.

bob carnie
20-Mar-2016, 12:54
The older paper had a really soft sticker that came off almost by blowing on it . this new paper the sticker really damages the surface.

to the point I will switch papers as this kind of wastage is not acceptable and on larger pieces where the image comes close to the edge the wastage would be 100% - some numb nuts is going to really lose their job over this or should,
I cannot see how this paper is viable for a user like myself in long term.


I have tried COT 320-like very much
I have tried Hanamuhle Lanaquelle - like very much

Seriously though who would put a dam sticker on art paper on the good side or even the back side its really unbelievable. If this is a factory thing then they have seriously made a mistake. At 17 dollars a sheet this
is unacceptable.

I'm pretty sure in my case the art store put the sticker on for the sole purpose of a bar code price. The platine from bostick and Sullivan has no sticker. If I were in your shoes I would ask for my money back or at least a 25% discount for the sheets you can't use. You are already paying a premium compared to us in the states!

bob carnie
20-Mar-2016, 13:09
I will check into this, the paper in 10 sheet packages is sealed with Canson labels so I think it happened there , which does not surprise me- I cannot see how the French would sabatouge their paper and if Bostick is not screwed up I wonder who is doing this.
I would hate to find out its my local retailer, as they are really good and this is unbelievable if its them , and I will become the bearer of bad news… At least they can't spit in my soup or fries in months to come every time I order.

I will post back.

the Canadian Dollar is really screwing me around.. You would be shocked at my costs for pt pd from Bostick getting to me in a timely manner.
