  3. Re: NEW BOOK: Finally, an easier and inexpensive (very) new technology for photogravu

    Boost. C'mon guys, photographers have been waiting 100 years for this gigantic advancement. Your blind, arthritic aunt Tillie can make photogravures with this approach.
    If they haven't been waiting...

    More apologies for not seeing this sooner. The inkjet dither is perfection. Never a single problem, EVER!!
  5. Re: NEW BOOK: Finally, an easier and inexpensive (very) new technology for photogravu

    Sorry for the delay in responding. I just don't get notices even though I have set it up to do so.

    I use a direct-to-plate approach with an Epson printer. The 'aquatint' screen is part of the...

    Doremus, thanks.
    Please pass the word whenever you can. So many newcomers have no idea.
  8. Re: New FREE paper on SLIMT contrast reduction for B&W and COLOR, film, paper, everyt

    Fagrid,
    My apologies for the late response. I just can’t seem to force the software here to send me notices of new posts.
    Extended development after bleaching does not / should not, restore the...

    I suppose it isn't "necessary", but neither are shoes. However, BOTH are damned convenient!! ;-)
  10. Re: New FREE paper on SLIMT contrast reduction for B&W and COLOR, film, paper, everyt

    Hi,
    Though the kit has Photographer's Formulary on the label, they are not selling it. They are only packaging it for Freestyle. So, you can't have bought it from PF.
    There are no sample images....
  11. Re: NEW BOOK: Finally, an easier and inexpensive (very) new technology for photogravu

    Just a nudge.
  12. Re: New FREE paper on SLIMT contrast reduction for B&W and COLOR, film, paper, everyt

    I have never used it with gas burst, though I did some investigations of gas burst agitation for Georgia Pacific years ago. I see no reason it shouldn't work.

    If you are using X-ray film, you may want to download the free paper I just posted on this forum on SLIMTs. It specifically discusses reducing the contrast of X-ray film with SLIMTs.

    In the early 1990's I published a 4-part series of articles on contrast reduction (contraction) in "Darkroom & Creative Camera Techniques" magazine. (I published a lot of articles, but this series is...
  17. Re: NEW BOOK: Finally, an easier and inexpensive (very) new technology for photogravu

    Direct-to-Plate means that instead of making an enlarged film positive (the films used to make positives for the photogravure process no longer exist), a temporary positive image is printed directly...

    My apologies for not posting this a couple of months ago, but better late than never.
