Using the Simple Image Quality
Adjustment (SIQA) Tools
Simple Image Quality Adjustment (SIQA) is a set of maintenance tools that adjust the
quality of the printed images generated by the press. SIQA performs three types of
adjustments:
Alignment: The Alignment procedure generates an individual alignment profile for
each stock/tray combination selected when performing the procedure. These profiles
ensure that images are placed correctly on the media. You can create a maximum
of 50 profiles. Each created profile is then automatically used each time the associated
stock is used, ensuring optimal print quality.
Density Uniformity: The Density Uniformity procedure adjusts print engine tables
to ensure that ink is deposited uniformly and consistently across the entire surface
of a page for each print.
Image Transfer: This tool corrects for uneven toner and color shift by creating an
Image Transfer Adjustment to the Bias Transfer Roll in the press. The adjustment is
created and saved for specific stocks and can be selected for any tray when printing
on those stocks.
These are the three sets of steps that are performed when calibrating the press with the
SIQA tools:
1. Print the SIQA targets.
2. Scan the targets using either the Document Feeder or the Platen Glass.
3. Save the adjustment data to a file on the press providing the file with a unique
name.
