Thermal transformative variable gloss control produces selectively variable levels of gloss finish on thermoformed materials. In embodiments, the power level of LED curing lamps associated with an ink jet printer that is using thermoforming inks for printing is selectively varied depending upon a desired level of gloss in a finished substrate. Heat treating of the substrate during thermoforming or in an oven develops the glossy finish on the substrate in relation to the level of power applied to the printer LED curing lamps during printing.

A method is provided for controlling a web in a printing apparatus The printing apparatus includes a transport assembly for moving the web through a transport path along a printing unit for printing an image onto a print area of the web. The method includes feeding the web from a supply roll through the transport path to the transport assembly; and switching the printing apparatus to a ready-to-print mode, wherein the printing unit does not print an image on the web and the web is maintained ready to be printed on. In a printing mode after the ready-to print mode, the following steps are performed: moving the web through the transport path in a transport direction along the printing unit by the transport assembly; and printing the image onto the print area of the web by the printing unit. The image is printed by applying an image material, which solidifies on the web during the printing step. The ready-to-print mode includes the step of: operating the transport assembly to prevent a deformation of the print area of the web in the transport path, while maintaining the web in the ready-to-print mode.
