Measurement is the basis of process control. The measurement of dot area coverage or dot percentage is fundamental to define the characteristics of our printing system, to calculate compensations of tonal values for plate making and, finally, to control the production. In 2017, a new method for the calculation of dot area percentage was [...]

The register between colors is a fundamental aspect for the quality of the printed product. But what is the correct register tolerance and how to evaluate it? ISO 12647-6 connects the register tolerance to the print linescreen. The higher the linescreen, the greater the expected accuracy on the printed product. According to this norm, register [...]
Surface texturing of flexographic plates is nowadays widely used to improve the ink laydown when using latest flat-top platemaking technologies. The settings for such surface micro screening are carefully evaluated during the optimization phase of system calibration and they shall not be changed for that printing condition. Using wrong settings will cause not only the [...]
Here is a print condition audit that initially revealed an insufficient quality level, scoring below 30%, and ended with a final score of 83% with satisfaction of both printer and final customer. The printer invested in 3 days of process calibration activities over 3 weeks time with the limitation of using the existing press setup [...]
