Abstract
A system for registering printing screens used for printing in series on a substrate which includes a plurality of outwardly projecting electrical switches, with a pair of the switches being positioned to engage a first side of a screen frame and at least one switch being positioned to engage a second side of the screen frame. The first and second sides of the frame are orthogonal relative to each other and, a pair of lights are activated by engagement of the frame with the switches, both of the lights being activated by simultaneous engagement of each of the switches by a screen frame. Similar sets of switches are provided on a table that supports the screens during exposure to an image to be replicated during printing and on a device that temporarily replaces a printing platen for alignment of each screen in a multi screen printing device.
