values that differ by less than 50%, you’re specifying a narrow range of shades that’s more likely to result in banding. If you have difficulty printing

smooth gradients without banding, try these techniques:

Use a gradient that changes at least 50% between two or more process color components.

Specify lighter colors, or shorten the length of dark gradients. Banding is most likely to occur between very dark colors and white.

Increase the percentage of change in the gradient.

Decrease the screen frequency for the document (PostScript output devices only).

If banding occurs in an imported graphic, such as an Adobe Illustrator® file, you might need to adjust the original graphic.

Print to a PostScript® 3 output device, which is capable of producing smoother gradients.

Use shorter gradients. The optimum length depends on the colors in the gradient, but try to keep gradients shorter than 7.5 inches.

About halftone dots and printer dots

Most printers simulate gray by using halftone dots printed on a grid; the grid cells are called halftone cells, and the grid rows are called lines or line

screens. Each halftone dot is made up of printer dots. As the halftone cell fills up with printer dots, the halftone dot gets larger, resulting in a darker

shade of gray.

Printer resolution determines the number of dots available to create the halftone dot. A printer with smaller dots can produce a wider variety of

halftone dot sizes, allowing more shades of gray. Screen frequency also plays a role: As screen frequency increases, the halftone cell gets

smaller, and so can hold fewer printer dots, resulting in fewer possible shades of gray. As a result, there is a trade-off between the number of

possible gray levels and image coarseness.
