Patent ID: 7415928

Claim:
A printing press adapted to print a material to be imprinted comprising: at least a first ink carrier, said at least first ink carrier being spaced at a first distance from the material to be imprinted; a print substance selected from a group of print substances having different material structure and applied to said at least first ink carrier; and at least first and second energy beams of first and second different wavelengths, each of said at least first and second energy beams being selectable to selectively transport radiation energy to said selected print substance on said at least first ink carrier, a transfer of at least a portion of said selected print substance from said at least first ink carrier to the material to be printed in response to a light-hydraulic effort stimulated in said selected print substance applied to said at least first ink carrier by said radiation energy transported to said selected print substance on said at least first ink carrier by said selected one of said at least first and second energy beams, each of whose selected wavelength stimulates a different one of said group of said print substances selectively applied to said at least first ink carrier.
