It’s time to change the way we measure to percentage!

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 [...]
