ABSTRACT:
An apparatus in a machine for processing printing material has a register sensor for register measurement between at least two color separations of a printed image printed above one another on a printing material. The register sensor registers optically deviations between two color separations lying one above the other on the printing material and forwards the deviations onto a computer. The apparatus includes register marks to be measured by the apparatus. The apparatus is distinguished in that the register sensor contains at least one photodiode having at least two quadrants, and in that the largely rectangular evaluation areas of the photodiode are aligned obliquely in relation to the edges of the conveyed printing material.
