Re: km73 plate with finer stochastic screen

That would be, "pop", not "pope". Yet both are, as has been demonstrated on numerous occasions, quite fallible.

Hi Loris,

Indeed! Astute observations on all accounts! ;-)

Wiping technique can affect highlights. In this case the print was on Rives BFK - Bright White, so the paper base is about as white as white can be. Plate tone is a common 'feature' with this process, however, which can add a tinge of dinginess (a desirable quality to some when executed properly!). The fact that I'm transposing from a print will degrade the 'pop' found in the original a little bit, as with any transfer process. Scanners are also quite unforgiving. The print in front of me seems to be quite poppy, but I agree the pope could be, and I expect, can be better.

Imagesetter transparencies rock if you can get 'em!

Imagesetters rock!

Nice print, lovely couple! :)

In my monitor, the polymer print lacks the specular highlights -> A
scanning artifact? Because of paper base? ... or ... Is this just normal
for photopolymer?

I wish printing presses were not that much expensive. I found a dealer
that stocks KM73 plates in Istanbul, now I have to find a school w/ a
printing press... Considering the cheap price for imagesetter negatives
here, I will probably try photopolymer process later (for making

Subject: km73 plate with finer stochastic screen

Hi All,

Here's a scan of an intaglio print I made today using the 1800 dpi stochastic screen, side-by-side with a scan of the original silver print. This is using the 2nd iteration of the compensation curve I've been developing for my workflow with the 7800. Not without room for improvement, but getting close! No adjustments were made to the 16bit RGB scan of the intaglio print, other than converting it to jpg. Auto-adjust was turned off in the scanner settings.

Please let me know what you think, and if you have any questions not already addressed in my on-line procedure.
