Disable hardware scaling and alternate shading
Two new resolution options have been added to the IPS software:
•
Disable Hardware Scaling
• Alternate Shading.
Disable hardware scaling
Disable Hardware Scaling is a new option for printers (IOTs) capable
of accepting 240, 300, or 600 dpi. This includes the 92C IPS with the
XRC1 board option and 180 IPS with the 240 spi kit. Disable
Hardware Scaling is an option on the Resolution panel of the printers
listed above.
If the Disable Hardware Scaling option is not selected (default), 240
and 300 dpi jobs are imaged at 240 or 300 dpi by the IPS Printer
Controller and scaled to 600 dpi by the IOT.
If Disable Hardware Scaling is selected, 240 and 300 dpi jobs are
imaged (and thus scaled) by the IPS Printer Controller.
Hardware scaling is faster (although the performance gain will not be
noticeable on all jobs) but software scaling can produce better results
for those applications that use resolution-independent resources
such as outline fonts, GOCA, and percent shading.
Alternate shading
Alternate shading is a new option for printers (IOTs) capable of
accepting 600 dpi. This includes the 92C IPS with the XRC1 board,
the 92C without the XRC1 board option, the 96 IPS, 180 IPS, and
4635 IPS. Alternate Shading is an option on the Resolution panel of
the printers listed above.
For the IPS 5.4 software release, shading patterns were developed
specifically for 600 dpi printing. These shading patterns are tuned to
produce better quality at 600 dpi. By default, the IPS Printer
Controller uses the 600 dpi shading patterns when configured to the
IOT.
When the Alternate Shading option is selected, the IPS Printer
Controller uses an alternate set of shading patterns, originally
developed for 300 dpi printing.
