The back of a Jagermeister shot glass I have has a "4 cl ARC" line. What does "ARC" mean?!

Question: I know the 4 cl means that the glass holds 4/100ths of a litre, but what is the ARC? There is a 2cl line also on the glass, but that does not say ARC after it. I know in Germany and other parts of Europe all of the glasses used in restaurants/bars must be labeled with volume.

Well, not sure but the first thing I thought of was the glassware manufacturer.

"In 1825 Arc International began production glass and crystal.
Currently Arc produces over two billion pieces of glassware annually.

Dinnerware, glassware, and accessories for your home.
Crystal glassware, vases, and more for fine dining or gifts.
Arc is also a major supplier to the food service industry."
