The calibration scale is the same test familiar to the eye of the average printer that print shop owners ask for.
This test is used to calibrate the printing process and to calibrate the control device of the printing machine – e.g. Axis Control, Image Control, Densitronic S, LITHEC Lithoscan Professional.

Of course, the test also identifies some defects in the sheet transfer system and the perfecting device. But it is not really applicable to testing a used machine – it demonstrates the technological features of a particular print shop.

Procedure:
During test printing, achieve optimum register alignment, check the operation of the spectrophotometric device, the powder sprayer. Pay attention on additional printing parameters. Set aside at least 5 test sheets and mark them as in the previous tests.
