When to use what
IF Rip’s are old Customers are very conventional Hardly any communication / connection with
printers side THEN
Stick to the old... (PDF/X-1a or GWG 1v4)
PDF standards & PDF/X-4
When to use what
IF RIP’s are modern (eg. APPE or similar technology) Good understanding with customers / designers on
file delivery, color management Need for flexibility in terms of editing, color
transformation, output in general (e.g. spot to CMYK, simulation on digital printing press)
You’re in the Packaging business THEN
Move to the new (PDF/X-4 or GWG2015)
