Black Mark Size and Position
Figure 30 • Recommended Black Mark Print on Back of Paper
(Only the “22 mm Mark”)
Print side Opposite to thermal coating side
Sensor position 45 mm before cutter,. The sensor position can be adjusted
sideways to the positions 22, 42, or 62 mm from right edge of
the A4-paper (25, 45, and 65 mm for letter paper) when seen
from the front of the printer. When the printer is delivered, the
sensor will be in the 22-mm position.
Mark length range 3 to 18 mm, default 5 mm
Mark width Minimum 5 mm centered on the sensor position, recommended
width is 10 mm
Print density Standard wet offset mode is recommended for printing of the
black-marks. The full mark area must be printed. Screen-
printing is not allowed. Measurement of print density must be
performed relative to the white paper background.
Using a MacBeth densitometer, the print density must be greater
than 1.3. Anti-gloss filter is not allowed. Using a Gretag
densitometer, the print density must be greater than 1.5. The
reflection from the black-mark must be less than 10%. The
reflection from the paper must exceed 80%.
Preprinting Preprinting in the zone passing over the black-mark sensor is
not recommended. If required, OCR blind type of ink must be
used, (outside the 700-1100 nm range).
Punched holes Punching must be done from the thermally coated side.
Distorted print can be expected within a zone of approximately
2-mm around the edges of the hole. The function must be tested.
