Thermal printing

Thermal printing is often used on ATM stamps to add the different values and sometimes other data needed while using the same basic label designs. Printed data usually have a characteristic dot pattern.

It is the same process used for printing retail store receipts which requires chemically coated paper.

However, be aware that like store receipts, exposure of ATM stamps printed this way to high heat will cause the paper to turn black. Otherwise, long-term preservation is a problem since thermal printing is impermanent and is not intended to be permanent. So just make sure that storage conditions are as close to ideal as possible, in a cool dry place not exposed to strong light.
