My concern is that the vender is stating the even if the RIP utilizes the Adobe Print Engine, colors, spot colors in this case, will be inconsistent. -- Steve Miller Color Management Specialist "Quality Begins Here" BIC Advertising & Promotional Products 1000 3rd Ave. SW Sleepy Eye, MN 56085 Tel.: (1) 507 794 8203 E-mail: slmiller@norwood.com www.norwood.com / www.bicgraphic.com CONFIDENTIALITY NOTICE This electronic message is confidential and may contain legally privileged information intended only for the use of the individual or company named above.

We've had terrible results printing any pdf via a RIP if transparency and spot color was involved. The explanation from out RIP vendor was that the problem was a result of the conversion process differing from Adobe's color engine. We've had to RIP files to tiff in photoshop first as a workaround.

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?
