Problems inherent in the copying and printing process
■
If you are trying to copy an original that was printed using a
“screen” process — where the image contains patterns of dots that
build tones and hues — copies may exhibit Moiré patterns. This
effect becomes more noticeable with coarser-patterned screens.
Depending on the image, you may see some improvement (or
some degradation) by placing the original on the glass at a slightly
different angle, or by copying it at a greater or smaller Scale
setting.

Some colors may vary significantly from the original’s. Different
printing processes use different kinds of inks; in particular, bright,
saturated, or metallic colors may not reproduce well.
You may be able to improve color matching somewhat using the
CopyStation’s Color Balance and Lighten/Darken controls.
