Operating Principles

2.2.2 Printing Operations

Micro Weave Mode
The Stylus Color IIs printer has a special printing mode, called "Micro Weave Printing Mode," which
can be selected from the custom printer driver. Using micro weave printing can improve the output
quality, because it eliminates banding that can sometimes occur in normal mode. In micro weave mode,
paper feed is performed after each print pass, eliminating pitch variations that cause the banding. The
table below shows the differences between the Stylus Color printer and the Stylus Color IIs printer in
the micro weave mode.

Normal Mode

This mode is specially designed to decrease banding lines when the printer uses black ink (a
low-penetrable type).
