Abstract
A digital flexography system includes an imaging member with a charge generating layer formed from an array of addressable pixels and a charge transport layer thereon. Ink is delivered to the imaging member using a simple rough donor roll, rather than an anilox roll. Instead of controlling the amount of ink delivered using the anilox roll, the amount of ink is controlled by the pixels on the imaging member.
Claims20
A flexographic printing system comprising:
- a nano-enabled imaging member comprising:
- an array of hole-injecting pixels, each pixel being electrically isolated and individually addressable;
- and
- a charge transport layer disposed over the array of hole-injecting pixels;
- a development subsystem comprising:
- a rough ink donor roll;
- and
- an ink supply.
