Abstract

A system and process for high speed molding to place printed images, particularly printed color images, on molded objects using a print medium composed of a substrate carrying a coating, the coating being adapted to retain printing inks and formulated to be releasable from the substrate after a molding process. Alternatively, the coating may be formulated to adhere to the substrate after the molding process. The portion of the print medium placed inside may be separated into segments or left in a continuous strip prior to placement in the mold. Images may also be placed on objects by printing directly on the surface of a mold, causing ink from the image to bond to the object formed upon closing the mold and injecting molded material into the mold cavity.
