Abstract
The invention concerns a method for cross-linking photosensitive inks in particular polymersible inks (36) by ultraviolet radiation consisting in a step (35) inking dots (31) on a base (38) and a subsequent step consisting in applying a concentrated ultraviolet beam (32) on the inked dots (31), except for the base non-inked surfaces (30). The beam is in particular an ultraviolet laser beam. The invention is applicable to jet dot-matrix printing and polychromy.

21. A method of cross-linking photosensitive inks, comprising the steps of:
-
printing ink dots on a support; and
selectively applying an ultraviolet beam to said support such that said beam irradiates the ink dots and is substantially inhibited from illuminating portions of the support which are devoid of ink. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28)

29. A system for printing an image onto a support, comprising:
-
a printing device which deposits ink dots of at least one color on the support to form the image; and
a curing device which selectively applies an ultraviolet beam to said support such that said beam irradiates the ink dots and is substantially inhibited from illuminating portions of the support which are devoid of ink. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36)

37. A system for printing a color image onto a support, comprising:
-
a plurality of printing devices each of which deposits ink dots of a respective color on the support to form the image; and
a least one curing device which selectively applies an ultraviolet beam to said support such that said beam irradiates the ink dots and is substantially inhibited from illuminating portions of the support which are devoid of ink. - View Dependent Claims (38, 39)
