Linagraph 1895 Direct Print

[Ash]

I got given a box of this stuff for free by the friendly owner of my vintage camera shop. He'd forgotten its use and it was stuck with the jobo tanks for the past 20 years probably. He thought it was some very slow kind of light sensitive paper, but may be good for all my experimentation work. I was also given a can of 'fixer' for the paper.

Some research revealed the stuff is used for laser applications, and it can't be wet processed.

I ripped off a section in the changing bag, re-sealed the box, and left the cut section in the light next to me. I took a small section and dunked it into a measuring cylinder of developer solution and BAM! grain!. It appears it might want to wash off though, as a rub of the thumb removed part of the layer.


Has anyone even HEARD of this stuff? Anyone experimented with it for something other than oscilliscopes?

Thanks.

Could it be one of the old things which were developed in ammonia fumes? My sinuses still hurt when I think of that stuff...

[Ash]

ammonia fumes?! :O

That must have been outlawed!!!

I've just managed to get a negative print on a piece of the paper (3rd attempt).

First attempt was overdeveloped, second attempt was out of focus, third attempt is a not-so-flattering photo of my dad asleep on the sunbed with the dog resting at his feet.

The stuff needs about 1 second exposure in bright sunlight, then a few seconds developer, then stop. I'm not bothering to use fix solutions. I'll scan the print in a moment.

So other than ammonia, what other non-'wet' processes are there?

Thanks

EDIT! Of course I was quick enough to realise i should fix regardless... and the paper returned from black to salvage-able by the time i got to it just now

I had to rush out soon after my reply when I realised I should have been at the cinema 5 minutes before I posted!

Here's a scan of the image:

Here's inverted:

Here's levelled.

Quite interesting, but 150ft of the stuff? hmm

EDIT: the rough processing has left all sorts of artefacts and undeveloped areas, hence the evident damaged look, and obscured areas on the levelled image

Hmm... my guess would be Linotronic paper - for use in a digital imagesetter.. in which case it's pretty similar to wet-process PMT/Lith paper for a stat camera.

Hey Ash, do you still have the paper? I use in for capturing lasers beams and it's hard to find.

Thanks,
