material, the storage and handling of the materials prior to
printing can also affect print quality.
Keep materials clean and dry. Surface contamination can
lessen ink adhesion, so surfaces should be clean and
individual sheets handled with gloves. Remove fingerprints
and other surface contamination with a clean, dry rag.
Rigid and flexible material guidelines
Most plastic materials are available in either sheet form or
as roll stock. In order to distinguish between flexible and
rigid for use on your QS Series printer, use the guidelines
below.
Rigid media
Materials 0.050" (1.270 mm) or thicker are assumed rigid
stock in all cases.
Stock 0.050" (1.270 mm) and thicker is not suitable to be
used in roll form, as it generally has too small of a bend
radius and would retain memory from the roll, causing head
strikes.
Flexible media
Materials 0.030" (0.762 mm) or thinner are flexible. While
available in sheet form, roll stock is best.
Rigid/flexible media
Materials between 0.050" and 0.030" (1.270 and 0.762 mm)
thick are in a transitional area between flexible and rigid.
Materials 0.040" (1.016 mm) thick fall in this area. You will
need to test whether a particular material is suitable for use
based on their circumstances. Consider productivity and
image quality when deciding on the correct feed mechanism.
