The Raster Image Processor uses information from the PostScript job and the
software print driver to determine which screen is used for a particular job.

What to Remember
Provides better coverage on rough paper
Larger dot provides better color stability
Reduces black and other solid color mottle
Provides better black coverage due to black toner
granularity
Dot size is better for impressions containing tints,
highlights, and pastels
Most suitable for pages requirement careful control of
highlights
Poorest performance on text
Produces fine rosettes that can better emulate offset
lithography.
May leave jaggies on text (fonts)
Better for creating smooth gradients with minimum
contouring
Best for graphics and images
Switch to the 200R screen if banding occurs
The angle is fixed and cannot be adjusted
Has vertical screening for black, which is better for text
and line art.
Switch to the 200C screen if banding occurs.
Best all-purpose screen.
Generally considered a special use screen.
Better edges on colored text with fewer jaggies.
Poor color stability due to small size of dot.
The entire color gamut must be reproduced in two-micron
area.
Least color stability due to small size of dot.
Not recommended for most workflows.
Used primarily for testing.
