APPARATUS TO ENSURE THE QUALITY OF PRINTED WORK

摘要

The specification describes a monitoring apparatus for the densiotometric evaluation of printed print monitoring strip. The apparatus consists of a common bracket with densitometers at selective mutual intervals forming gaps between themselves for the exclusive full tone density measurements. A second set of densitometers are insertable in the gaps between the first set of densitometers for measuring the full tone and/ or screen tone values necessary for mathematical correlation into quality accessing parameters.
