driver. Otherwise, both the application and the
printer manage colors during printing, and
document colors are corrected twice, which
causes unwanted color shifts.
When the PostScript printer converts
document colors, the color management
feature must be enabled in the printer driver.
Only PostScript printers and RIP engines that
support printer color conversions can be used
in this advanced method. Although it increases
the file size, this method has the advantage of
ensuring consistent colors when you send the
same print job to different print service
providers.
For more information about reproducing
colors for print, see “Printing colors accurately”
in the Help.
You can also manage colors in PDF files that
you create for commercial printing. For more
information, see “Specifying color
management options for exporting PDF files”
in the Help.
Using a safe CMYK workflow
Often, you may use specific CMYK color values
in your projects. To ensure reliable color
reproduction, you may obtain these CMYK
color values from a color swatch book. By
preserving these CMYK color values
throughout the printing process, you can help
prevent unwanted color conversions and
ensure that colors are reproduced as they
appear in the original design. A workflow that
preserves the CMYK color values is known as a
“safe“ CMYK workflow.
CorelDRAW Graphics Suite supports a safe
CMYK workflow. By default, CMYK color values
are preserved in any document that you open,
import, or paste. Also, CMYK color values are
preserved by default when you print
documents.
In some cases, you may want to bypass the safe
CMYK workflow and preserve the appearance
of CMYK colors when you open, import, or
paste documents. This option is useful when
you want to see the original colors of a design
on-screen, or view a copy that is printed to a
desktop printer. To preserve the appearance of
CMYK colors, you can set color management
policies that convert CMYK colors in
documents that you open, import, or paste. In
addition, when printing to a PostScript printer,
you can convert CMYK colors to the printer
color profile by disabling the Preserve CMYK
numbers check box on the Color page of the
Print dialog box.
Managing colors for online
viewing
Managing colors for online viewing can be
even more complex than managing colors for
print. Documents and images on the Web are
displayed on a wide variety of monitors, which
are often uncalibrated. In addition, most Web
browsers do not support color management
and ignore the color profiles that are
embedded in files.
When you design documents for exclusive Web
use, it is recommended that you use the sRGB
color profile as your document RGB color
profile and choose RGB colors. If a document
contains a different color profile, you should
convert document colors to sRGB before saving
the document for use on the Web.
When you create a PDF file for online viewing,
you can embed color profiles in the file to
reproduce colors consistently in Adobe®
Reader® and Adobe Acrobat. For more
information, see “To specify color
