Printing on the Inside of a Mug?

[Andrew]

Not ceramic though as the inside of a mug is not coated.

I did hear through the grapevine that a well known heat press manufacturer and well known mug supplier are working on something, so hopefully this question will be a thing of the past soon!

It was carrying on from the plastic mug option...... should have clarified.

I think its a great idea for anyone in this business to book a tour of a business that makes the Sub mugs - you will learn a lot about how they are produced (mugs and other things) as this will save you some time when working out if you can make the tools to overcome a problem.. like sub printing on the inside of mugs.

As out Tall Friend quite rightly says, there is no coating at all on the inside but I want to know why SOME Mugs have NO coating on the base - you would think they would all have a coating there due to the way the coatings are applied
