Coins, Medals & Precious metals

Coloured coins, where parts of the minted motif are coloured, are becoming increasingly popular. At the same time, the colour application brings additional variety.

We have developed a unique inkjet printing system for printing and colouring coins, medals and precious metals.

Precise alignment of the coin blanks before printing is crucial for a perfect printing result on the three-dimensionally embossed reliefs. In addition, the ink application must be so stable that the coloured coins survive the final rolling process undamaged.

Up to now, the printing of coins and other precious metals was mainly done by pad printing.

Thieme has developed a new type of digital coin printer that considerably accelerates the printing process. The inkjet printing system, which is unique on the market, works with tested special inks that guarantee optimum adhesion and abrasion resistance of the ink application on the metal substrates.

The system offers a total of seven colour channels (CMYK, white as well as primer and top coat); a fluorescent clear coat is also available for special lighting effects.
