Tim Quinn outlines the G7 method for calibrating and printing to Neutral Print Density in all printing processes
The G7 method for calibrating and printing to Neutral Print Density (NPD) is becoming more popular in all printing processes.
As a means of control in 4-colour process printing, NPD provides a shared appearance in the same image printed across multiple platforms, and the ability to achieve and maintain colour within a production run, as well as from run to run, in the screen, digital, offset and flexo printing industries.
