Color emulation
Your printer can emulate the color behavior of other devices: RGB devices such as monitors, and CMYK
devices such as presses and printers.
You can set color emulation in the following ways:
●
In the Windows PostScript driver dialog: select the Color tab, and Printer Managed Colors.
●
In the Mac OS Print dialog: select the Color Options panel, then select Printer from the Color
Management list.
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.
The options are as follows.
CMYK color emulation
A traditional workflow defines color in the CMYK space. For best results, the colors must be adjusted to the
printer, because different printers will produce different colors from the same CMYK data. If the image file
you are printing was not created specifically for your printer, it will require some readjustment, which can be
done using one of the following options provided with your printer.
●
None (Native): no emulation. The printer will use its default internal conversion from CMYK to RGB,
without following any color standard. This does not imply that results will be bad
