Operation
The G1-5 and G 1-7 printability testers consist of an exchangeable engraved printing disc, a doctor blade and an impression cylinder. Ink is applied with a disposable pipette between the doctor blade and the printing disc and after the image is printed, the doctor blade and the printing disc are lifted automatically.

The printing speed can be adjusted in five steps and two consecutive prints are made automatically. The second print is the one used for evaluation as it is the most consistent.
