a smaller number of line segments, resulting in curves which
appeared flat (for example, circles that appear like stop signs).
Many legacy files still contain high flatness values, but newer
RIPs (and the Distiller) can cope without raising the flatness
value. This feature assists these legacy files by pretending to
increase the flatness value, but letting the RIP render paths as
smoothly as it can.
Note: The maximum resolution that still requires flatness control is 600
dpi. It is not necessary to control flatness if the device resolution is
greater than this value. This check is not done in Distiller.
CreoScitex Artwork Systems ArtPro Separations v1.0
This feature rewrites some ArtPro procsets more efficiently to
ensure better performance.
Adobe OPI Helper v1.5
The Prinergy normalize function uses an Adobe OPI merging
engine. This feature corrects several bugs in that engine. Recent
additions to this feature support Adobe PageMaker colorized
images correctly. The PageMaker bug would cause tinted
images to be output at 100% intensity, rather than as set in the
document for composite workflows.
Minimum Line Width v1.4
Many legacy applications generate PostScript that draws very
thin lines (hairlines), expecting that the output will be
appropriate for 300 or 600 dpi devices. When device
resolutions increase to 2400 dpi, these thin lines seem to
disappear, especially on a printing press. This is because the
PostScript requests the smallest possible line (for example, a
single device pixel). At 300 dpi, one device pixel is equal to
0.24 pt. At 2400 dpi, one device pixel is equal to 0.03 pt.
This feature monitors and modifies PostScript requests for line
thickness, and ensures that the smallest thickness request is
0.216 pt or larger so the lines will appear even on high
resolution devices. This check and enforcement works even
when the input PostScript is scaled.
Control Smoothness v1.0
This feature enables or disables smoothness settings in files
and resets the initial smoothness value to 0.002, which seems
to be a good value for all RIPs.
