Hi wenlh,
i think ai & Pdf feature "Transparency" issue.
what kind of your RIP, EFI, EFI(embedded),Creo, KM brands??
it is true support PDF 1.4 or above??
if your RIP unsupport PDF 1.4 or above??
if you want safey to digital printing.
ai print -> setting Transparency Flattener option -> high resolution
acro print -> setting Transparency Flattener option -> high resolution
remark: please don’t direct drop PDF file to RIP hotfolder or queue,
because your RIP unsupport PDF 1.4 or above!!
hope helpful!
best regards,
bananababy
