necessary to limit the run-length of high-coverage jobs, and to run multiple batches separated by low
coverage jobs. For example, to optimize print quality on a high-coverage job requiring 500 copies, it might
be best to run 10 jobs at 50 copies per job.
The toner saver function allows for a toner savings of up to 35%. Two modes are available; gamut-protect
and maximum savings. The maximum savings mode will produce the greatest toner savings, while the
gamut-protect mode optimizes print quality by ensuring no change in color gamut occurs when the toner
savings algorithms are used.
Paper
The IBM InfoPrint Color 100 accepts paper web widths of 19.7 to 20" (500 mm - 508 mm). Print quality
specifications apply only when using the IBM-approved papers. See the IBM InfoPrint Color 100 Print
Media Guide for the current list of approved media. This list is updated from time to time as IBM approves
additional media. You can download the IBM InfoPrint Color 100 Print Media Guide from the following
internet address:

Upon request, an IBM customer engineer will install paper scripts.
Print Area
The InfoPrint Color 100 prints to within 3 mm (0.12 in.) of the edge of the paper roll, and provides a
maximum image width of 475 mm (18.70 in.). Maintain at least 5 mm (0.2 in.) space between printed
images. Signature space along the web can be within 0.1 mm if no cutting is required. If cutting is
required, signature spacing should be at least 1.0 mm. Cutter accuracy is 0.5 mm.
Registration
Color Registration: Use the automated registration procedure (via the densitometer) to adjust the
registration of the print unit stations. The IBM InfoPrint Color 100 Operator's Guide describes the
procedure. Usually, registration is adjusted at the start of a new paper roll or after an idle period of more
than two hours.
Image Registration: The InfoPrint Color 100 image registration is within ±0.75 mm (0.03 in.) in the paper
movement direction, and within ±1 mm (0.04 in.) across the web. The operator can adjust alignment to
within 1 pixel of the ideal location. Back to front image registration is within 0.2 mm (0.008 in.).
Skew
Image skew and distortion have an accuracy of ±0.02°.
Sheet Cutting Accuracy
The accuracy of the cut length is ±0.5 mm (0.02 in.). The cut is perpendicular to within 0.3°.
Optical Density
Hold optical density as close as possible to specifications to ensure full process color reproduction and
consistency of color throughout any particular job. The IBM InfoPrint Color 100: Operator's Guide
describes optical density adjustments. A densitometer is shipped with the printer to check optical density.
