The COLOP e-mark Ruler is for perfect positioning of imprints. Small objects or objects that are printed close to edges can be printed very easily with the Ruler. The surface of the Ruler keeps constant contact with the optical sensor so you can print easily and quickly. It is convenient for ribbons, wristbands, labels or signs.
For the perfect positioning, you should select centre as the start position in the app (Where does the e-mark (create) start to print? How do I position it correctly?). Then the recess on the Ruler can be used for positioning. You can print from left to right or vice versa. Simply place the e-mark at the respective edge and print, thus the max. imprint length of 150 mm can be used.
