Should I always save as PDF x-3 2002?
In school I was instructed to always use PDF x-3 2002 when printing a poster (I think so that we be compatible with the school plotter). Does that setting ensure colors stay the same when printed/best printing quality?
I am having a hard time getting rid of those thin white lines that show up on Adobe PDFs sometimes and it looks like if I save my file with a different PDF format I can get rid of those lines. But I want it to print well with accurate colors, is PDF x-3 2002 the best? Or can I use the "high printing quality" option with good results as well?
Thanks.
