Embodiment Construction

[0048] refer to figure 1 A thermal transfer printer 1 includes an ink-carrying ribbon 2 extending between two spools, a supply spool 3 and a take-up spool 4 . In use, ribbon 2 is passed from supply spool 3 around rollers 5 , 6 , past thermal print head 7 , to take-up spool 4 . The rollers 5, 6 may be idler rollers and serve to guide the ribbon 2 along a predetermined path. The print head 7 is mounted on a print head support 8 . The ribbon 2 is driven between a supply spool 3 and a take-up spool 4 under the control of the printer controller 10 . Ribbon 2 may be conveyed between supply spool 3 and take-up spool 4 in any convenient manner. One method for transferring ribbon is described in our earlier patent, US Patent No. 7,150,572, the contents of which are hereby incorporated by reference.

[0049] In a printing operation, the ink carried on the ribbon 2 is transferred to the substrate 9 to be printed thereon. In order to effect ink transfer, the print head 7 is brought i...

Abstract

A method of operating a thermal transfer printer, the thermal transfer printer comprising: first and second spool supports each being configured to support a spool of ribbon; a ribbon drive configured to cause movement of ribbon from the first spool support to the second spool support along a predetermined ribbon path; and a printhead, the printhead being a corner edge printhead. The printhead is configured to selectively transfer ink from the ribbon to a substrate as the substrate and printhead are moved relative to one another at a print speed. The method comprises transferring ink from the ribbon to the substrate when the print speed is less than 40 millimetres per second.

Description

technical field [0001] The present invention relates to printing, and more particularly to thermal transfer printers and methods for controlling such printers. Background technique [0002] Thermal transfer printers use ink-carrying ribbons. In a printing operation, the ink carried on the ribbon is transferred to the substrate to be printed. To effect ink transfer, the printhead is brought into contact with the ribbon, and the ribbon is brought into contact with the substrate. The printhead contains printing elements that, when heated, cause ink to be transferred from the ribbon and onto the substrate while in contact with the ribbon. Ink will be transferred from the area of ​​the ribbon adjacent to the heated printing element. An image can be printed on a substrate by selectively heating printing elements corresponding to areas of the image that require ink transfer and not heating printing elements corresponding to areas of the image that do not require ink transfer. ...
