Printing Rich Black, Pure Black, and Print Black

Follow the steps below to match black information  in imported images to QuarkXPress objects or text where black is applied.
  1. Determine the CMYK black build from the current Photoshop Working CMYK Profile.
  2. Select QuarkXPress 7.0 Default as your default Source Setup in the Color Manager preferences pane of the QuarkXPress Preferences dialog.
  3. Select Enable Access to Picture Profiles in the Color Manager preferences pane.

    Note: Consult the Background and More Information sections below for additional notes on printing Rich Black, Pure Black, and Print Black.
Background:
When working with black regions in your layout, it is possible to have black mismatches between imported images created in other applications and objects created in QuarkXPress, even though you have only chosen a straight CMYK black for QuarkXPress objects or text. These mismatches occur when:
  1. Converting RGB black to CMYK black,

  2. Designing using the straight CMYK black, or

  3. Building rich blacks.
Mismatches between different types of black may be difficult to see on a monitor, but you can often detect differences in display when you view the blacks next to each other. For example, when RGB black (R0, G0, B0) is converted to 4-color CMYK black in Photoshop, the RGB black information is transformed to C-63, M-52, Y-51, K-100 in the CMYK color space. When an image is printed with these values, the resulting black prints noticeably darker than a CMYK black with values of 0,0,0,100. A rich black will result in a darker, shinier black at the press. A straight 100% black will result in a duller, matte-like finish. This occurs because less ink is being laid down on a particular region of a page. If you are working in a color-managed workflow, black information can undergo color transforms if the profile for the source and target devices have significant conversions defined for black. For more information on color managed workflows please refer to: the QXP User Guide PDF file (located in the Documents folder of your QuarkXPress folder), pp.142 ff.

Note!: The CMYK black build will be entirely dependent on the working CMYK profile chosen in PhotoshopÂ’s Color Settings. This is in addition to either the source profile of the image or the working RGB profile chosen in PhotoshopÂ’s Color settings.

Note!: Ultimately you will want to consult with your prepress department or with your service burreau customer service representative to determine how you should be defining your rich black or regular black information for specific jobs.
