Note

The default print resolution is 1200 dpi. 600 dpi printing may be adequate for your job. Try setting

your resolution to 600 dpi to improve the RIP performance of complex 1200 dpi jobs. 1200 dpi results

in four times the internal image data of a comparable 600 dpi image that has to be transferred

through the system. When the print resolution is changed from 1200 to 600 dpi, the stroke thickening

value may also need to be changed from 1 to 0 to avoid excessive line thickening.

• It is common to embed logos and watermarks in submitted print files. These are typically bitmap

images that, when embedded in a print stream (such as PostScript), can take a long time to process.

Note also that resolution selections, such as 600 dpi vs. 1200 dpi, can have a significant further

impact on processing of these types of embedded images. Consider the design of documents and

impacts to printing speed in such cases. There are methods available, through PostScript for example,

to cache these embedded images, process them once, and retain them as a resource for application

on each page without having to render and scale them for each page. Refer to your PostScript

reference manuals and FreeFlow Print Server reference manuals for information about caching.

• Submission of multiple TIFF images simultaneously is a common application. There are several batch

printing tools available on the market. Most of them require the selection of a print driver for the

target printer through which these images files are submitted. In these cases, the TIFF files are

converted to a Printer Description Language (PDL), such as PostScript, by the batch tool using the

printer driver. Then they are submitted to the printer, which in turn RIPs that PDL and re-renders the

TIFF bitmap images back into bitmaps. This is an inefficient process that can significantly slow the

machine down. Nuvera includes a native TIFF interpreter that can process TIFF files sent to it directly.

Some of the batch tools on the market support a native TIFF submission capability. It may be referred

to as a bypass mode or something similar. If such a capability is available, the Nuvera's performance

can be significantly improved by taking advantage of that capability.

Note

When printing to a DFA-compliant 3rd party finisher, do not select Bypass Transport as the output

location.

• The PDF Optimization feature should not be used when printing PDFs that were saved in FreeFlow

Print Server using the RIP Save or Scan to File selections. These types of documents will take much

longer to RIP when PDF Optimization is enabled. Before enabling PDF Optimization, it is recommended

that the user run performance tests using representative customer jobs.
