Systems and methods for printing data on a substrate including a color-changeable material are provided. One system includes a processing circuit and a device including an energy source. At least a portion of a printed publication is printed on the substrate using a commercial printing press based on fixed data. The device including the energy source is configured to add variable data to the substrate. The processing circuit is configured to receive the variable data and to control the energy source to change a color of the color-changeable material based on the variable data to provide at least a portion of the printed publication. The processing circuit is configured to control the energy source to change the color of the color-changeable material in-line with a flow of the substrate through one of a printing line, a finishing line, or a packaging line of the commercial printing press.

Printing using color changeable material

In one embodiment, provided is a system for printing data on a flexible substrate that has a color-changeable materials associated therewith. The system comprises a data source that may be configured to provide data to be printed on the flexible substrate, a processing circuit, and an energy source. The processing circuit may be configured to retrieve the data from the data source and to control the energy source to change a color of the color-changeable material based on the retrieved data.

The invention relates to a method for replacing a rejected book on a binding line.
