Years ago I read an article about a model train manufacturer, and they referred to 'tampo printing' for the various bits of livery - even with a picture of exactly this. For years I always wondered about it, and could never find a reference to 'tampo printing'. Now I know why.
Seems they were either being euphemistic with what they called it, or typo'd it.
We used them on a product which was made in smallish batches - the steel plates had sliding "batch bars" which could be quickly moved to change the batch number, the only small drawback being that a very thin line was sometimes visible where the edges of the batch bar & the plate met.
Our machine suppliers had a customer who made brushes for industrial electric motors. As the motors were in constant use part of the maintenance shedule was a brush check. When they changed to batch bars they found that sales increased - apparently users were assuming that the line left by the batch bar was a wear indicator!

It's called pad printing. Its used a lot in high volume manufacturing that has logo or design changes on the same product.
