Specify halftone frequency and resolution

Last updated on Jun 2, 2026

Learn how to configure halftone screen frequency (lpi) and printer resolution (dpi) to control dot spacing and image quality for commercial printing in Adobe InDesign.

InDesign lets you set halftone screen options in the Print dialog box for commercial output like film separations or press-ready files. Halftone screens simulate continuous tone by arranging printer dots into lines, measured in lines per inch (lpi). Higher screen frequencies (around 150 lpi) produce fine detail for magazines, while lower frequencies (60–85 lpi) work better for newspapers. Always confirm recommended screen settings with your print provider, since some devices override custom values.

Select preset screen frequencies

Open your document and select File > Print.

In the Print dialog box, select the Output tab.

In the Screening menu, choose a preset combination that pairs screen frequency (lpi) with printer resolution (dpi). The Screening menu displays recommended line screen and resolution combinations based on your selected PPD file. These preset pairings are optimized for common commercial printing scenarios.

Review the selected settings and select Print.

Customize screen frequency for individual inks

Open your document and select File > Print.

In the Print dialog box, select the Output tab.

In the ink list, select the specific plate (color separation) you want to customize. Custom halftone settings override preset combinations.

In the Frequency field, type the desired screen frequency value in lines per inch.

In the Angle field, type the screen angle value in degrees.

Note

The values you enter in the Frequency and Angle fields update dynamically as you select different inks in the list, showing the current settings for each separation.

Repeat for additional plates if needed, then select Print.

The screen angle prevents visible row patterns by rotating line screens at different angles for each ink. Standard angles are: Cyan 105°, Magenta 75°, Yellow 90°, and Black 45°. Your service provider may specify different angles for their press.

Understanding the relationship between screen frequency, resolution, and printing press capabilities ensures optimal output quality. A 150 lpi screen requires higher resolution (2400 dpi or greater) than an 85 lpi screen (1270 dpi). Mismatched settings may reduce image quality rather than improving it.
