Printing ceramic baking pan design- GIF

Pad transfer printing. The product is glazed and fired, for markings about as durable as this casserole dish for oven service.

Another version, hot-stamping, uses raised figures on a silicone sheet, the 'die'. The silicone is bonded to .06-.09 aluminum, perimeter drilled for flat head screws. It's heated by wire elements,while a paint covered film transfers the impression, film is dispensed from a spool.
Very common for graduating measuring cups and polyplastic containers. They can be oven-use (glass or ceramic) or not, but dishwasher safe.
Built numerous fixtures for these, aligning some mark, say 4 quarts to a felt tip mark, filled with that amount. The sets had long service life, until the pad became damaged. Not exactly rocket science, but the company had lots of different containers.
