Xerox Disclosure Journal
The present disclosure relates to a means of providing an ink~fieldsurface for lithographic printing. A uniformly dispersed population of ink and fountain solution containing capsules is secured to or embedded in a substrate such as polyester plastic sheeting or woven cloth. In operation, the ink field web is disposed around the ink cylinder, and when the ink cylinder rotates with its surface in contact with the master cylinder, the ink and fountain solution capsules are crushed releasing the ink and fountain solution evenly over the ink cylinder surface, The substrate is periodically advanced in the printing sequence to refresh and maintain an optimum supply of ink and fountain solution over the working ink-field surface.
