I've been doing some research with PDF files and RIPs. We want to have a
PDF only workflow and one RIP vender is saying we should not use PDF
files. Instead, they recommend .eps, .tif or .jpg.
Here's a reply from one RIP vender.
"The pdf print engine is implemented as a base feature in the" (enter any
vender name here) " RIP programs. It has advanced handling of pdf and pdfx
file formats. It was necessary for" (enter any vender name here) "to add
this feature due to Adobe's constant alteration of the pdf encoding
process and handling of transparencies, spot color handling in gradients,
and compression methods. There is a basic flaw in the conversion of spot
color in the pdf format to the rastered ink dots of an inkjet printer.
This is a problem that all RIPs have.. It is a problem inherent in the pdf
format being rendered into the inkjet dot format. The repeat printability
of colors suffers in this format. While Adobe also alters the EPS format,
color consistency from print to print is stable."
Is this a true statement?
