3.2.2 Media calibration
Media calibration ensures that the sensor is able to recognize the markers. OPOS is
calibrated at the factory to work on a wide range of media. However, certain media -- such
as those with a high gloss -- may not work with the default settings. Before working with
such materials, perform a media calibration test. This test will alter OPOS’s sensitivity so that
it will read the markers with greater reliability.
Print a square measuring at least 4x4cm on the media that will be used. Be sure to use the
same ink that will be used when creating the registration markers.
NOTE: It is not recommended to do media calibration for OPOS. If the media calibration is
done and results are not better, then set the media calibration value again to default : 30
(see further in the procedure how).
Doing media calibration:
1. Turn on the cutter and load the vinyl with the printed square.
2. Press .
The main menu will appear on screen.
3. Press .
The configuration menus will appear on screen.
4. Press .
The different OPOS configuration menus will appear on screen.
5. Press .
The cutter allows the user to choose to either measure the media or to fill in a previously
recorded value.
NOTE: If a combination of media color – marker color has already been calibrated and
recorded, then can be used to enter this value directly, without having to
remeasure it.
6. Press .
The cutter will lower the sensor. On the display, the message ”put knife on white area” will
appear.
7. Use , , or to maneuver the knife on top of a white
area (the area should be at least 3 by 3 cm or 1” by 1”).
