Hello all,
I am new here as well as flexographic printing world.
I am a graphic designer and I need to learn the pre-press requirements to send artworks for flexo printing.
couple of questions.
1- Do vector artworks need to be all subtracted from each other so there is no hidden shapes underneath?
2-how can I create the trapping on my artwork so the print company will see it and make the plates accordingly?
3-why do I need to worry about LPI and Print angle and halftone type? I read a pre press requirement from a company that says"Use a screen value of 42.5 dpi for half tone images. Use only 10%, 20% and 30% line value. and Halftone images in Mezzotints are more corrugated friendly than dots". Aren't these the adjstments that printing company does when sending the artwork for plate making machine?
Thank you in advance
also I would appreciate if you can give me any other advise for flexo printing art requirement so it will make the process easy on the print company.
Alex
