Abstract:
1. An ink jet printing device, comprising a controller, an ink jet print head and a print region surface toward which ink is jetted from the ink jet print head, wherein a height distance between the ink jet print head and the print region surface is adjustable, and a fixing device that fixes the ink jetted from the ink jet print head to the print region surface by a contact force that directly applies pressure and optional heat to the ink jetted from the print head, wherein the ink jet print head is capable of printing either regular height prints when the ink jet head is set at a minimum height distance from the print region surface, or raised height prints when the ink jet print head is at a distance greater than the minimum distance from the print region surface, the controller controls the ink jet print head to incrementally adjust the height distance between the ink jet print head and a previously applied ink layer after each layer of a raised height print is printed, the adjustable height distance comprises: when the ink jet print head is positioned so as to be spaced from the print region surface a distance corresponding to the first height distance, the ink jet print head prints ink images having an individual layer regular height of about 5 μm to about 10 μm, and when the ink jet print head is positioned so as to be spaced from the print region surface a distance corresponding to the second height distance, the print head prints ink images having a raised height of at least about 80 μm or more.
