• Use shorter blends. The optimum length depends on the colors in your blend, but try to
keep blends shorter than 7.5 inches. (See “
Calculating the maximum blend length
based on the color change” on page 339.)
• Use lighter colors or make dark blends short. Banding is most likely to occur between
very dark colors and white.
• Use an appropriate line screen that retains 256 levels of gray.
• When the document contains complex artwork, transparencies, gradients, mesh
objects, or blends, make sure that you have selected the right resolution and Quality/
Speed settings in the Document Setup dialog box. (See “
Printing and saving trans-
parent artwork” on page 336.)
Ensuring your resolution/line screen produces 256 grays
In printing your file, you may find that the resolution of your printer, when combined with
the chosen line screen, allows fewer than 256 levels of gray. A higher screen frequency
decreases the levels of gray available to the printer. (For example, if you are printing at a
resolution of 2400 dpi, using a line screen higher than 150 results in fewer than 256 levels
of gray.)
The following table lists the maximum line screens you can use with printers to maintain
all 256 levels of gray:
