Hello, I'm a graphic designer and I work with pre-press. Using Illustrator to create or modify files (check below CS3 and CS5), amount of files in InDesign (version (CS3 and CS5) from here I do films for the separation by creating a file. PS and then distilled with Adobe Distiller, then send the PDF NEGATIVE created a service (with an old AGFA AccuSet 800) that I developed the film. My problem is as follows: making films in the photo negative unity "Burn" all shades of Illustrator, costing all rasterized.
Note: films with a positive problem does not exist!
Do you know what it can depend on?
