The following are the most commonly used device color spaces and profiles:

RGB mode:

sRGB (sRGB IEC61966-2.1): for images that typically originate from consumer digital

cameras and scanners and from the Web

Adobe® RGB (1998): for images that typically originate from professional digital cameras

Specific RGB device space: for images that are coming from or going to a specific RGB

device that has been profiled

CMYK mode:

SWOP: Specifications for Web Offset Publications, a set of press standards that have been

defined for a typical U.S. press and for different types of paper stock

ISO 12647-2: a set of press standards that have been defined by the International Standards

Organization for different types of paper. Some examples of the definitions include Coated,

Uncoated, and so on.

Other regional standards: Euroscale, JMPA, Japan Color

Specific CMYK device space: for images that are coming from or going to a specific CMYK

device that has been profiled. The HP Designjet Z6100 printer can measure itself and generate

an CMYK ICC profile, describing its color behavior for the paper that was loaded when it

calculated the measurement.

Color and your printer

As a creative professional, predictable and dependable results from your printer are essential to getting

your job done. Predictability is a key element of an efficient color workflow. You need prints that match

your expectations and that generate neutral grays and correct colors on your selected paper, print-to-print

and printer-to-printer. Dependability ensures that every print is free of print-quality defects and ready to

use or send to your customer. You save time and effort and avoid wasting ink and paper, and you can

meet demanding production schedules with confidence.

HP Designjet Z6100 printers have been engineered with advanced hardware and driver features to ensure

predictable and dependable results, and offer dramatic improvements in efficiency and control for your

color workflow.

HP Embedded Spectrophotometer

HP Designjet Z6100 printer series revolutionizes professional color workflows by using a built-in

spectrophotometer for color calibration and profiling.

A spectrophotometer is a precision instrument that can determine the exact composition of the light that

is reflected from a color patch. It splits the reflected light into different wavelength components and

measures the strength of each component. The HP Embedded Spectrophotometer is mounted on the

printhead carriage.

The HP Designjet Z6100 printers use the spectrophotometer to generate custom ICC profiles automatically

for your preferred paper types. It then calibrates the printers to deliver print-to-print and printer-to-printer

consistency with less than half the color error of earlier HP Designjets, under all environmental conditions,

and even on unknown (not factory-profiled) paper types. A built-in white calibration tile, which is protected

by an automatic shutter, ensures reliable measurements that meet international standards.

The printer, color-imaging pipeline, and professional-quality spectrophotometer with GretagMacbeth i1

color technology are integrated with the HP Color Center software for the HP Designjet Z6100. Giving

the calibration and profiling processes direct access to the writing system allows precise control of ink

levels and color separations for each printed color patch. The automated measurement process eliminates
