System information

CMYK/Grayscale Processing Method
The CMYK Processing Method option allows you to define the CMYK-to-CMYK conversion method for the
CMYK data in a print job.
•
Pure Primaries - If your Fiery Server supports this setting, it outputs the primary colors in a job (C only, M
only, or Y only) as primary colors, using only a single colorant. The result is pure-looking primary colors, with
minimal banding in gradients.
Pure Primaries compromises overall color accuracy. Do not use Pure Primaries if color accuracy is
important, such as when printing press proofs.
•
Quick - If your Fiery Server supports this setting, it applies one-dimensional transfer curves to adjust output
densities in the cyan, magenta, yellow, and black channels. This technique leads to eye-pleasing color output
because pure primary colors are not contaminated by other colorants. Do not use Quick for final documents
that are used as press proofs. Other methods offer better color accuracy.
•
Full (Source GCR) - Provides a complete and accurate simulation based on colorimetric transformations. Hues
are preserved, even for primary colors. The gray component replacement (GCR) level that was specified in the
original (source) document is approximated. However in some cases, if the black colorant is not dark enough by
itself to render the darkest tones in the source color space, CMY is added to the output black for better color
accuracy. Process black expressed in CMY is reproduced using CMY colorants.
This method can be used to preserve pure black objects without converting them to CMYK. However, the Gray
(CMYK) option is a more typical method for preserving pure black.
•
Full (Output GCR) - Provides a complete and accurate simulation based on colorimetric transformations. Hues
are preserved, even for primary colors. With this method, the Gray Component Replacement (GCR) level that
was specified in the original document is not preserved. Instead, all CMYK data is reseparated using the GCR
level specified by the output profile. This simulation technique is similar to traditional ICC color-matching
methods and is more appropriate than Full (Source GCR) for full-color printing designed for a traditional
press, but reproduced on your printer.
Note: When you specify Pure Black On for Black Text and Graphics, and Full (Output GCR) or Full (Source
GCR) for CMYK Processing Method, the black text and graphics in your document are printed with 100% black.
Black Point Compensation
The Black Point Compensation option lets you control the output quality of shadow areas for CMYK source
colors.
Use Black Point Compensation to enhance details in shadows when the CMYK source space is larger than the
gamut of the printer. In proofing applications, when the CMYK source space is smaller than the gamut of the
printer, do not use this option.
Black Point Compensation is supported for a Fiery Server with FS150/!50 Pro software or later.
Note: For RGB source colors, black point compensation is always applied.
Black point compensation works by scaling the source colors so that the darkest point in the source profile maps to
the darkest point in the output profile.
