Automatic Numbering machines are a time saving device commonly used in many industries. They can be set in many different configurations to perform a set number of tasks. Their most common task however is numbering that changes each time you stamp. You can set your first number as anything (eg: 100) and stamp from 100, 101 etc. or whatever configuration you like. They can be supplied in 5, 6, 7, 8 wheel configurations. Auto numbering ink is specially designed for metal numbering wheels and as such should not be used with rubber stamps. Ink is generally supplied in 28ml bottles and comes in Black, Blue & Red. A small felt ink pad is used to hold the ink and like a self inking stamp, auto numberers re-ink themselves with each impression.
