AutoTran, Inc. has a unique cup design, which is used throughout its line. The cups are made of a solvent resistant polymer and designed for ease in cleanup. The ink reservoir in the inkcup is deep enough to hold enough ink to run all day and wide enough to get you finger inside the trough for simple cleanup. All cups are designed with covered magnets so there is no erosion of the magnet coating and hence scratching of your plates. Available in sizes 2.5", 3.5", 5.0", 6.0" and 7.0". All rings are double sided ceramic and are available in the cup sizes listed above.
