Specifying custom printer resolutions (halftone screen ruling)
If a preset printer resolution doesn't suit your needs, you can use the Output options of the Print dialog box to specify a custom one for each plate in the separation. Note however, that the default angles and frequencies are determined by the selected PPD file. Check with your print shop for the preferred frequency and angle before creating your own halftone screens.
To specify a custom halftone screen ruling: - Double-click the name of the color plate to be customized (listed under Document Ink Options.
- Do any of the following and click OK:
- Enter the lpi value in the Frequency text box.
- Enter a screen angle value in the Angle text box.
- Select the shape for the printed dot from the Dot Shape pop-up menu.
You can also enter the frequency and screen angle directly in the Document Ink Options list by clicking on the existing value and entering a new one. You can also click the dot shape listed and choose a new shape from the menu that appears.
