MaxLight™ XL4 pre-inked stamps are fully assembled and ready to be “flashed”. MaxLight™ XL4 and PSI™ stamps utilize the same die box, thus the imprint area is identical. The foam and cartridge are already in place. Simply remove a film strip to allow ink to flow to the printing surface. If you add ink yourself, simply open the back door of the die box and fill the slot with MaxLight™ Ink. Inking your own stamps makes inventory easier to control, reduces your cost and speeds the migration of the ink. The stamp will be ready in 15-30 minutes). Imagine what buying stamps pre-assembled does to your ordering process (all items are included with one product code). Imagine what it does to your assembly time (we think it reduces it by 25%).
