The HP Designjet 50ps printer has six ink cartridges for the four basic colors of the CMYK color space; therefore, spot colors must be converted for output with these four colors. Normally, spot color conversion is based on the CMYK values defined in the original application for the respective color.
The HP Designjet 50ps PrintManager, however, also allows to define custom spot colors and to edit the spot color conversion settings. In this way, you can exactly define how the HP Designjet 50ps printer is to output the respective color in CMYK.
-
Click Inks in the Settings panel.
-
Click Create new spot color.
-
Now type the name of the spot color and define the CMYK composition for this color. When entering the name, make sure to type it correctly because only spot colors defined under exactly this name in the application can be assigned and converted accordingly.
-
Clicking Adopt causes the current name and the CMYK composition to be adopted. The top line of the detailed view changes accordingly, and a preview of the color is displayed.
-
Then save the new color by clicking OK.
Custom colors can be deleted again by clicking the trashcan icon.
Note: Using the supplied Pantone® tables, the most common spot colors can also be automatically converted to provide optimum settings for the respective paper types and print qualities. For this purpose, you only need to enable the Automatic Pantone® Calibration option in the Color management panel for the job or the virtual printer. For details, refer to Tell me about color management--Automatic Pantone® Calibration.
Note: Even when the Automatic Pantone® Calibration option is enabled, the spot colors defined on an individual basis will be used first.
