● CMYK mode:
● SWOP: abbreviation of “Specifications for Web Offset Publications”, a set of press standards
defined for a typical US press and for different types of paper
● ISO 12647-2: a set of press standards defined by the International Standards Organization
for different types of paper (Coated, Uncoated, …)
● Other regional standards: Euroscale, JMPA, Japan Color
● Specific CMYK device space: for images coming from or going to a specific CMYK device

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 with neutral grays and correct colors on your selected paper. Your prints should be
produced consistently 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 by printing overnight with
confidence.
HP Designjet Z3100 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 Z3100 printers revolutionize 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 light reflected
from a color patch. It splits the reflected light into different wavelength components, just as Newton’s
prism splits white light into the colors of the rainbow, and measures the strength of each component.
The HP Embedded Spectrophotometer is mounted on the printhead carriage.
The spectrophotometer allows HP Designjet Z3100 printers to generate custom ICC profiles
automatically for your preferred paper types and calibrate the printers to deliver print-to-print and printer-
to-printer repeatability 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,
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 Z3100. 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 handling the test print, provides repeatable drying times, and allows fast measurements with
precise electromechanical positioning of the spectrophotometer over the color patch. This provides
unprecedented ease of use and matches or exceeds the performance of more expensive off-line,
handheld profiling systems.
