PUB98: Two-Color Gradients Don't Print Correctly in Spot Color (179253)



The information in this article applies to:

  • Microsoft Publisher 98

This article was previously published under Q179253

SYMPTOMS

If you create spot color separations from a publication that has two-color gradient fills, those gradients are reduced to a single color gradient when the color separations are printed. For example, if you are using red and blue as your two spot colors, and you have a gradient fill that goes from red to blue, the gradient will be printed on the red plate, not the blue plate, when you print the color separations.

CAUSE

Publisher does not provide a different halftone screen angle for each color plate. Because this feature is necessary to correctly separate two-color gradients, Publisher reduces two-color gradients to a single color.

RESOLUTION

If your publication requires a two-color gradient, you should consider printing it on a digital color printer instead of a printing press.

STATUS

This feature is under review and will be considered for inclusion in a future release. Microsoft welcomes suggestions or comments about changes in functionality and product design. You are invited to submit suggestions by filling out the form at the following Microsoft Web site:

MORE INFORMATION

When you use a printing press, you achieve the effect of lighter and darker colors by a process called halftoning. A halftone is a pattern of dots that make a region of ink look lighter than the ink color.

When you print a color separated print job on a printing press, each sheet of paper goes through the printing press three times (or through three different printing presses). Each pass through the printing press adds another color of ink to the paper. If different colors of ink overlap, the dots that make up the halftone pattern may also overlap. At best, overlapping halftones appear muddy. At worst, they create an unwanted stripe effect called a moire pattern.
