Use the halftones attribute to specify the screen-frequency attribute values. (See halftone for more information.) The screen-frequency attribute is supported to maintain downward compatibility, but it is not the recommended attribute for specifying the screen frequency to use for printing halftones.
Indicates the screen frequency, in lines per inch, to use for printing halftones.
Resettable, single-valued, per-document
You can enter one of these fixed values:
- This attribute is valid only for GIF, JPEG, PDF, PostScript, and TIFF documents.
- Change the screen frequency if you see moire or two-dimensional repeating patterns in halftone images.
- Set the screen frequency to 106 if you see dark and light bands in printed output, with halftone images possibly showing a herringbone pattern under magnification.
- InfoPrint validates and schedules jobs using this attribute against the destination attribute screen-frequencies-supported.
