IPDS printing environment

Color image support

Some IM1 images (for example, logos) can be converted to IOCA for resolution correction. The bi-level IOCA feature enables such IM1 images to be printed in color on the highlight-color printer. PSF does not strip the color information from the print job.

Also supported are JPEG compressed IOCA, as well as JPEG and EPS files in object containers.

NOTE: Hosts may not support JPEG files in object containers.

Background color for OCA colors

Users can specify COLOR on DRAWBOX (i.e., background color) as long as the color is restricted to colors defined with the OCA model.

Bi-level IOCA colors

The printer accepts the new IOCA color spaces in the extended controls (referred to as the “4E” color triplets). These include the Highlight Color and Standard OCA Color.

Outline font support

The printer supports the use of IBM outline fonts for both single- byte and double-byte applications. These fonts must be downloaded during the jobs.

These outline fonts allow users to specify a single font that can be rasterized in a variety of point sizes by the printer. The IBM outline fonts are based on Adobe type 1 and type 0 fonts that are in PostScript format.
