HP (Hewlett-Packard) PCL 5 Printer User Manual


 
The Driver Configuration command provides a way for a
driver to calibrate the output by adjusting color
lightness, saturation, and color map information.
All of these methods of modifying output color are
explained in the following sections.
Halftone Render
Algorithms
The HP color printers have the capability of applying
different halftone render algorithms to achieve the desired
output on the printed image. Render algorithms allow you
to change the characteristics of the image by changing the
way pixels are rendered. Each halftone render algorithm
produces a different affect on the output, varying the
texture and color appearance of the printed image.
To choose the type of rendering to be used, use the Render
Algorithm command, described below. This command
allows you to choose one of the existing rendering
algorithms or to choose a user-defined pattern created with
the Download Dither Matrix command.

The Render Algorithm command selects the algorithm to be
used for rendering page marking entities on a given page.
