Reject preseparated jobs
Prevents RIP from processing preseparated jobs.
Recombine preseparated jobs
Recombines certain classes of preseparated jobs. Recombining is useful when
proofing to a composite device or retargeting from one device to another. Jobs
eligible for recombination must consist of process separations, suitable spot
colors, or both. Suitable means the job supplies a CMYK equivalent for a spot
color or an equivalent is found in the definition files found in the "MicroPress/
Rip/Trsysm01/SW/NamedColor" folder. You can add a CMYK equivalent
definition to these files.

New
Adds a spot color separation. Name entered must perfectly match one used in
the job in every respect (e.g., same case, use of embedded space characters,
any trailing CV or CU suffixes). A typical Pantone specification is PANTONE
386 CV, but applications may report this differently.

Delete
Deletes a spot color separation. Process color separations cannot be deleted.

Dot Shape
Screening is the process of approximating gray levels or color shades with a
pattern of dots. Dots are built using pixels and occupy a halftone cell that
represents a gray level or color intensity. A dot can occupy 0% of the area in a
cell (white) to 100% of the area (black). Dots of intermediate areas simulate
gray. The number of pixels assigned to a halftone cell defines how many gray
levels are available.
The MP-RIP
offers a variety
of dot shapes.
Selecting the
appropriate one
depends on the
output device,
resolution, media, and image type. E.g., Euclidean dot-shapes produce better
saturated grays above 50%, especially at finer screen frequencies, because it
fills halftone cells from the corners, instead of the centers, when the gray value
exceeds 50%. When the gray value is less than 50%, the dots are filled from
the center.

Common Dot Shapes
Round
Commonly
used dot
shape, but
dot gain can
be a
problem in
shadow areas since the white diamond at the center of four adjoining circles
can easily become filled with black as the dot size grows. But round dots give a
smooth appearance in the highlights and middle tones.

Euclidean
This dot shape reduces dot gain in the shadow areas and is good for general-
purpose use. (It is common in newspaper production, for example.)
