Transfer Printing Information

Screen Printed Transfers

The majority of heat transfers used in the plastic moulding industry are manufactured by the screen printing process. Multiple colour graphics added value to the identification of products. Plastic manufacturers found that heat transfers eliminated multiple set-ups and related problems associated with wet ink printing processes. The decorating process could be accomplished next to the moulding press rather than in a separate climate controlled area.
