Abstract
A system and method for printing aqueous ink jet ink in selected areas of nonabsorbent and semi-nonabsorbent substrates includes applying an ink-receptive coating in the selected areas, for example with printing station having a printing and drying unit for applying the ink-receptive coating in the desired area or areas of the substrate and then drying the coating, and printing an aqueous ink jet ink in the coated area with an ink jet printer. Variable print maybe printed with the in jet ink in a high speed process.
Claims36
A method of printing an aqueous ink on at least one selected area of a nonabsorbent and semi-nonabsorbent substrate, comprising steps of:
- applying an ink-receptive coating to the selected area of the substrate,
- at least partially drying the coating,
- and printing an aqueous ink jet ink on the coating.
A method of printing variable print in selected areas on a nonabsorbent or semi-nonabsorbent web or roll of a substrate, comprising steps of:
- applying an ink-receptive coating to the selected areas,
- at least partially drying the coating,
- and printing an aqueous ink jet ink on the coating in variable print.
A method of continuously printing variable print in selected areas on sheets of nonabsorbent or semi-nonabsorbent substrate, comprising steps of:
- applying to the selected area on each sheet an ink-receptive coating;
- at least partially drying the coating;
- and
- printing an aqueous ink jet ink in variable print in the area with an ink jet printer.
A method of printing variable text on nonabsorbent or semi-nonabsorbent substrate using a printing press having multiple print stations, comprising steps of:
- applying repetitive print with one to less than all of the print stations;
- applying an ink-receptive coating in a selected area of the substrate with one of the print stations;
- at least partially drying or curing the ink-receptive coating;
- and
- applying a waterborne ink in the area of the ink receptive coating to form a variable print using an ink jet printer.
A system for printing variable text in a selected area of a nonabsorbent or semi-nonabsorbent substrate, comprising
- a press with a printing station having a printing unit that applies an ink-receptive coating to the selected area and
- an ink jet printer positioned to apply a variable print in the coated area.
A mail table, comprising
- a print station that applies an ink-receptive coating in one or more areas of a nonabsorbent or semi-nonabsorbent, printed sheet fed onto the mail table,
- a heater that at least partially dries the applied coating or a source of actinic radiation that at least partially cures the applied coating, and
- an ink jet print head that applies a variable print to the one or more areas using an aqueous ink.
