Technical

specification

11.1 Label Material

The printer is equally suitable for thermal transfer printing. Three factors are to be taken into
account when choosing the material:

y

Abrasive behaviour of the surface structure

y

Properties with respect to chemical reaction on print-colour transfer

y

Temperature required for colour- transfer

If the material is extremely abrasive, the print head is faster worn as usual. This criterion is
particularly to be considered with thermal printing. It is not so critical with thermal transfer
printing, as for this process a ribbon of a width exceeding the width of the material can be used.
In this way the print head is protected over the entire material width.
Similar conditions prevail with a high print head temperature. Material and foil require a longer
cooling down period, the printing quality is more critical and the print head is faster worn as on
a normal rate.
Printing on materials with a higher specific weight than 240gr/sqm, slight corrections of print
head pressure and position of print head may be necessary.


11.2 Thermal transfer foil

Foil are recommended to be:

y

the rear side has to be coated with an anti static and friction reducing media (back coating)

y

suitable for print speeds up to 12 inches/second

y

specified to „Near edge type print head“

y

wider as the material, i. e. the foil overlap the edges of the material by appr. 1-2 mm each
side.

CAUTION! - Foil without these features may reduce printer performance and
printing quality, in some cases even the print head may become defect.
