About printer Color emulation modes Your printer can emulate the color behavior of other devices: RGB devices such as monitors, and CMYK devices such as presses and printers. See Select the color emulation mode on page 69. If you have problems making your printer emulate another HP Designjet printer, seeColor matching between different HP Designjets on page 157. For a good emulation, the printer needs a specification of the colors these devices can reproduce. The standard way of encapsulating such information is in ICC profiles. As part of the solution, we provide the most common standards for the different devices. Apart from selecting the appropriate ICC profile, you should select the appropriate rendering intent depending on the type of print: business presentation, photography or proof. See Set the rendering intent on page 69. For reference information on the broader aspects of color printing refer to: http://www.hp.com/hpinfo/community/environment/productinfo/ psis_inkjet.htm The options are as follows. NOTE: PDF and PostScript files can be used with PostScript printers only. CMYK color emulation All CMYK emulation options apply to PDF, PostScript, TIFF and JPEG files only. ● None (Native): no emulation, for use when the color conversion is done by the application or operating system, and therefore the data arrive at the printer already color-managed. ● HP CMYK Plus: a set of HP proprietary re-rendering rules that will produce a good result for most digital commercial printing jobs, by expanding the reduced gamut of your press into the wider gamut of your printer. ● U.S. Sheetfed Coated 2 uses specifications designed to produce quality separations using U.S. inks under the following printing conditions: 350% total area of ink coverage, negative plate, bright white offset stock ● U.S. Sheetfed Uncoated 2 uses specifications designed to produce quality separations using U.S. inks under the following printing conditions: 260% total area of ink coverage, negative plate, uncoated white offset stock ● U.S. Web Coated (SWOP) 2 uses specifications designed to produce quality separations using U.S. inks under the following printing conditions: 300% total area of ink coverage, negative plate, coated publication-grade stock ● U.S. Web Uncoated 2 uses specifications designed to produce quality separations using U.S. inks under the following printing conditions: 260% total area of ink coverage, negative plate, uncoated white offset stock ● Euroscale Coated 2 uses specifications designed to produce quality separations using Euroscale inks under the following printing conditions: 350% total area of ink coverage, positive plate, bright white coated stock ● Euroscale Uncoated 2 uses specifications designed to produce quality separations using Euroscale inks under the following printing conditions: 260% total area of ink coverage, positive plate, uncoated white offset stock ● JMPA: Japanese standard for offset press ● Photoshop 4 Default CMYK ● Photoshop 5 Default CMYK ● Other HP Designjet printers can be emulated 190 Chapter 21 Tell me about...
