The Process

The process for pad printing on glass is like any other pad printing job. The differences lie in the pad and in the pad printing ink. For large wraps on glassware, a hollow pad is suggested. For simple logos on the front, either a round or rectangular pad will work best. The decision on which pad is optimal for your glass printing project is discussed during the purchasing process. The pad printing ink, on the other hand, has been chosen from the start. CG pad printing ink for glass by Inkcups showcases the best adhesion and vibrancy properties on glass and ceramic products. This series comes in a variety of colors including high density colors and metallics. The CG Series is also classified as Non-Toxic and the pigment is made free from heavy metals.

Post Treatment

After the glassware items have been printed, the products are heated to ensure full dishwasher resistance. The heating seals the bond between the pad printing ink for glass and the product itself. While heating is not necessary for all glass applications, it is done to most because of the increased dishwasher resistance.



Shot glasses are the perfect product to pad print as they are very small in diameter and usually do not require too many colors.


Pint glasses for chain restaurants or bars need the best adhesion possible because of the constant washing and high temperatures.
