Abstract
A method of printing a printed output of a press comprising ink on a print medium applies ink to a surface, places individually controlled drops of aqueous solution onto the print medium in a drop pattern, and transfers ink from the surface to areas of the print medium that are free of aqueous solution to produce the printed output of the press. A method of variable printing is also disclosed.
Claims25
A method for printing a printed output of a press comprising ink on a print medium, the method comprising the steps of:
- applying ink to a surface;
- placing individually controlled drops of aqueous solution onto the print medium in a drop pattern;
- and
- transferring ink from the surface to areas of the print medium that are free of the aqueous solution to produce the printed output of the press;
- wherein the aqueous solution on the print medium substantially prevents transfer of the ink to areas of the print medium that have aqueous solution.
A method for variable printing, comprising the steps of:
- reserving a first area of a plate for variable information to be printed, wherein the plate further includes a second area of the plate for static information to be printed;
- applying ink to the plate;
- applying an aqueous solution to an area of a substrate on a controllable point by point basis to define the variable information;
- and
- transferring the ink from the plate to the substrate to print the variable and static information on the substrate;
- wherein the applied aqueous solution substantially prevents transfer of the ink to the second area of the substrate that has the aqueous solution.
