The RIP applies some optimizations to the handling of 1-bit (halftoned) images supplied at the exact resolution of the final device: for example, copy-dot scans. There are restrictions on which items are subject to optimization. The items must
be all of the following: exactly at the device resolution, imaged with matching X-axes (not rotated), produced by image
or imagemask
(but not masked image masks), not contone or RLE, and not inside a pattern. Given these characteristics the optimization is automatic in page setups that produce screened, monochrome output, at exactly the resolution of the scanned image.
This parameter allows the optimizations to be disabled, by setting the parameter to false
, but this slows down processing for the matching cases and should only be needed in exceptional cases.
Default: true
