Abstract
A control device manages an electronically actuated device for the purpose of ejecting liquids onto a substrate in a controlled manner.
Claims16
A digital press comprising:
- plural print heads disposed in an array across a travel path of a substrate to be printed;
- plural print head controllers, each print head controller controlling an associated print head;
- and
- an external processing system for controlling and managing operation of the plural print head controllers, the processing system storing an image to be printed on to the substrate and rasterizing the image into strips of digital data, each strip being digitally transferred to a separate print head controller
- whereby the associated print head produces high volume printouts of the same or substantially the same image,
- wherein the print heads are disposed in spaced relation across the substrate travel path, and
- wherein the spaced print heads are joined by adjusting members for selectively altering a distance between adjacent print heads.

A method of controlling a plurality of spaced print heads, wherein the spaced print heads are joined by adjusting members for selectively altering a distance between adjacent print heads comprising the steps of:
- rasterizing an image into strips of digital data;
- transferring each strip of data to a different print head controller that controls an associated print head;
- storing the strip of data in each print head controller;
- printing an image where each print head prints a separate strip of the image and coordinating a position of the print heads to form a complete image, and
- adjusting a position of one or more print heads.
