Color management There are two basic approaches to color management for your printer: ● Application-Managed Colors: in this case your application program must convert the colors of your image to the color space of your printer and paper type, using the ICC profile embedded in the image and the ICC profile of your printer and paper type. ● Printer-Managed Colors: in this case your application program sends your image to the printer without any color conversion, and the printer converts the colors to its own color space. Color management is done using a set of stored color tables; ICC profiles are not used. This method is somewhat less versatile than the previous methods, but is a little simpler and faster, and can produce good results with standard HP paper types. NOTE: There are only two color spaces that the printer can convert to its own color space using the stored color tables: Adobe RGB and sRGB if you are using Windows, Adobe RGB and ColorSync if you are using Mac OS. ColorSync is the Mac OS built-in Color Management System; so, in fact, when selecting ColorSync it is the built-in color management part of Mac OS that is performing the color management, and it is done based on the ICC profiles of specified paper type. ColorSync is available with the PCL driver only. You are recommended to consult the Knowledge Center at http://www.hp.com/go/knowledge_center/ djt610/ to see how to use the color management options of your particular application. To choose between Application-Managed Colors and Printer-Managed Colors: ● In the Windows driver dialog: select the Color tab. ● In the Mac OS Print dialog: select the Paper Type/Quality panel, then Color. ● In some applications: you can make this choice in the application. Printer emulation If you want to print a particular job and to see approximately the same colors that you would get from printing the same job on a different HP Designjet printer, you can use the emulation mode provided by your printer. NOTE: This option is available only when printing an HP-GL/2 job. It will work correctly only when printing on plain, coated, or heavyweight coated paper. ● In the Windows HP-GL/2 driver dialog: select the Color tab, then Printer Managed Colors, then select Printer Emulation from the Source Profile list. You can then select from the Emulated Printer list. ● In the Mac OS Print dialog: select the Paper Type/Quality panel, then Color > Printer Managed Colors > Emulated Printer. Color adjustment options The aim of color management is to print accurate colors. If you perform color management correctly, then you should be able to print accurate colors with no need of any manual color adjustments. However, manual adjustments may be useful in the following situations: ● If your color management is not working correctly for some reason ● If you want colors that are subjectively pleasing rather than accurate The printer driver provides different adjustment facilities depending on whether you are printing in color or in grayscale. If you are printing in pure black and white, there are no color adjustment options. 58 Chapter 7 Color management ENWW
