Mug Printing Machine is a device used for printing images, designs or text onto mugs or cups. Mug printing machines use a heat transfer process to transfer the design onto the mug surface.The machine typically consists of a heating element, a control panel, and a mug bed or holder where the mug is placed. The design or image is first printed on a special transfer paper using a regular inkjet printer or a specialized mug printing ink. The transfer paper is then placed on the mug, and the mug is clamped onto the mug bed. The heating element then heats up the mug and the transfer paper, causing the design to transfer onto the mug surface.
