2.3.1 THERMAL PRINTING ON PRE-PRINTED FORMS
Thermal printing technology also enables printing on pre-printed paper. However, a few things must be observed to avoid
damaging the sensitive printhead. The use of pre-printed paper increases the before mentioned effect. Since the
preprinted ink is located between the printhead and the heat-sensitive layer, it must be able to withstand high thermal and
mechanical loads. Unfortunately, even the best printing ink is not as resilient as a good thermal paper. This can result in
larger build ups during the printing process than with standard thermal paper. Therefore, the following rules must be
observed:
Rules for printing on pre-printed paper:
•
The color coverage in the printing areas should be kept to a minimum, max. 25% ink application, preferably zero.
•
Only using specified thermal printing inks with a minimum temperature tolerance of 230°C, recommended 250°C.
•
Do not print on sensitive, metallic or luminescent paints. Hologram foil should be placed outside of the printing
area.
•
Never use opaque white in the printing area.
•
The heat output (blackening) must not be increased.
•
When printing on pre-printed paper, the density parameter 18,6 must not exceed value of 25. It is recommended
to reduce the parameter to a value of 22.
Attention:
The printer, presenter and cutter motors are not designed to print continuously without a break at any temperature. The printer
motor can be monitored by a temperature sensor to prevent damage. The thermal behavior should be observed by the customer
to ensure that the system remains stable at very high ambient temperatures.
