Abstract
A reusable printing plate for recess or relief printing. The reusable printing plate features a number of adjacent printing cells, each of which can be independently alternated between a printing mode and a non-printing mode. In the printing mode the printing cell acquires a configuration for receiving and retaining a printing substance. In the non-printing mode the printing cell acquires a configuration which does not receive and retain the printing substance.
Claims21
A reusable printing plate for recess or relief printing, the reusable printing plate comprising:
- (a) plurality of adjacent printing cells, each of said plurality of adjacent printing cells being independently alternatable at least between a printing mode, in which a printing cell of said plurality of adjacent printing cells acquires a first configuration adapted for receiving and retaining thereat a printing substance, and a non-printing mode, in which a printing cell of said plurality of adjacent printing cells acquires a second configuration adapted for not receiving or retaining thereat the printing substance;
- and
- (b) an internal mechanism for independently alternating each of said plurality of adjacent printing cells between said printing and non-printing modes.
A recess or relief printing method comprising the steps of:
- (a) providing a reusable printing plate including a plurality of adjacent printing cells, each of said plurality of adjacent printing cells being independently alternatable at least between a printing mode, in which a printing cell of said plurality of adjacent printing cells acquires a configuration adapted for receiving and retaining thereat a printing substance, and a non-printing mode, in which a printing cell of said plurality of adjacent printing cells acquires a configuration adapted for not receiving or retaining thereat a printing substance, each of said adjacent printing cells including a stationary guiding element and a translating element translatable within said stationary guiding element;
- (b) further providing a mechanism for independently alternating each of said plurality of adjacent printing cells between said printing and non-printing modes by selectively translating said translating elements with respect to their stationary guiding elements;
- (c) via said mechanism, selecting printing cells of said plurality of adjacent printing cells to be in said printing mode;
- (d) providing printing cells being in said printing mode with said printing substance;
- and
- (e) transferring at least a portion of said printing substance from said printing cells being in said printing mode to a printable substrate.
A printing system comprising:
- (a) a reusable printing plate for recess or relief printing including a plurality of adjacent printing cells, each of said plurality of adjacent printing cells being independently alternatable at least between a printing mode, in which a printing cell of said plurality of adjacent printing cells acquires a first configuration adapted for receiving and retaining thereat a printing substance, and a non-printing mode, in which a printing cell of said plurality of adjacent printing cells acquires a second configuration adapted for not receiving or retaining thereat the printing substance, each of said adjacent printing cells including a stationary guiding element and a translating element translatable within said stationary guiding element;
- and
- (b) an external mechanism for independently alternating each of said plurality of adjacent printing cells between said printing and non-printing modes.
A reusable printing plate for recess or relief printing, the reusable printing plate comprising a plurality of adjacent printing cells, each of said plurality of adjacent printing cells being independently alternatable at least between a printing mode, in which a printing cell of said plurality of adjacent printing cells acquires a first configuration adapted for receiving and retaining thereat a printing substance, and a non-printing mode, in which a printing cell of said plurality of adjacent printing cells acquires a second configuration adapted for not receiving or retaining thereat the printing substance, each of said adjacent printing cells including a stationary guiding element and a translating element translatable within said stationary guide element.
