I am working with ImagOn, a photopolymer film, to make etching plates from my photos. To do this you expose this film twice: once with an aquatint screen and then again with a transparency positive of your image. (the screen creates a necessary grain on the film that when developed will hold the etching ink for printing).
So, I’m trying to create inkjet transparencies with the screen pattern "built in" instead of making a pre-exposure with an aquatint screen first.
Does anyone one know how to do this, and what DPI or LPI is needed (and other settings) to emulate an aquatint screen?
I’m playing with this method: converting my image to grayscale, then converting to Bitmap using one of these methods:
– diffusion dither (which seems to create a random pattern of dots/specs on the image, but doesn’t call for me to make any decisions about the pattern or ‘dot’ size),
or
– halftone screen, which does require some choices on my part such as frequency (lines per inch), angle in degrees, and shape (such as diamond, elipse, line, etc). I tried this at 720 LPI, 180 degrees and diamond shape, but I’m not sure what is correct.
Best, David.
