Abstract

Printing screens are registered using a photosensitive position locating sensor which is affixed to a pallet and aligned with the image of a register mark on the first of a series of printing screens. The location of the image is stored and signalled in a display device. The pallet is then roughly aligned with a second and subsequent screens of the series. The subsequent screens are each moved until the image of its register mark is superimposed upon the stored image. The signal output from the sensor is applied to a microprocessor which controls the display device.
