If you are confident that your PDF input files are press-ready, you can choose to bypass the refine process. Bypassing refine ensures that the content does not change, and saves processing time and resources.
Important: This feature should not be used for files that are of unknown quality or are prone to problems. For such files, a full refine (including the normalization, color conversion, and optimization) is best. The general recommendation for input files is to still do a full refine.
Press-ready PDFs
A press-ready PDF file is a file for which the printer only needs to impose, perform a last Prinergy Virtual Proofing System (VPS) check, and do the final output. The printer site is not expected to perform any modifications on the input files, since the publisher has checked that color conversion has taken place, traps and overprints are present in the file, preflight problems have been corrected, fonts have been included, the file RIPs correctly, and so on. The printer assumes that all settings in the files are as the page-preparation site intends on final output.
The bypass refine process
To bypass refine, process your PDF input files using the Bypass Refine process template, which only registers your PDF input files with associated colorant and geometry attributes into the Prinergy system; it does not change the contents of the file.
Important: Because no preflighting or corrections are performed, take care to proof your output. You should proof to an appropriate separation-capable proofer, such as to the Prinergy VPS software or to a Trendsetter Spectrum platesetter, to ensure that the separations and page content RIP and output as expected.
Note: Apparent document size discrepancy between input and refined PDF as seen in Workshop is a result of information that is added to the refined page. That is, colorant information is put into the PDF to allow Workshop to display painted colorants for each file.
