Color management generate an RGB ICC profile, describing its color behavior for the paper that was loaded at the time of measuring. ● 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 that has been profiled 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 Z3100ps GP 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 Z3100ps GP 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 Z3100ps GP printers to generate custom ICC profiles automatically for your preferred paper types and calibrate the printers to deliver print-to-print and printerto-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 Z3100ps GP. 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. 66 Chapter 6 Color management ENWW
