Embodiment approach 1

[0036] The invention provides an error correction method for a thermal transfer printer. The error correction method can combine the first preset position of the pattern of the graphic information (the pattern or text printed on the printing medium through the printer) and the electronic document (the printer is used to print the electronic document of the graphic information, the pattern of the electronic document and The position error between the second preset positions of the patterns with the same pattern of the graphic information) is controlled within a preset range. The first preset position may be any position in the pattern of the graphic information. The second preset position may be any position in the pattern of the electronic document. In this way, in this embodiment, error compensation can be performed on all contents of the pattern. It should be noted that the position error can be positive or negative.

[0037] In this embodiment, if figure 1 As shown, the...

Embodiment approach 2

[0057] Steps S1 to S6 in the second embodiment are substantially the same as steps S1 to S6 in the first embodiment. The difference between Embodiment 2 and Embodiment 1 is that Step S3 and Step S5 of Embodiment 2 also include the following steps:

[0058] In this embodiment, step S3 further includes determining a second time compensation value according to the length position error and the rotation speed of the platen roller arranged below the print head.

[0059] In this embodiment, a rotary encoder may be provided on the platen roller in the printer, and then the rotational speed of the platen roller may be obtained through the rotary encoder. Determine the error rotation angle of the platen roller corresponding to the length position error according to the length position error and the diameter of the platen roller (during the printing process of the thermal transfer printer, when the platen roller rotates the error rotation angle, the printing medium moves to the length p...

Abstract

The invention provides a thermal transfer printer and an error correction method thereof. The method comprises the following steps: acquiring a first distance between a first preset position and a first reference position of image-text information, and acquiring a second distance between a second preset position and a second reference position of an electronic document; determining a position error according to the first distance and the second distance, specifically, the position error comprises a length position error in the moving direction of a printing medium; determining a first time compensation value according to the length position error and the moving speed of the printing medium; acquiring the current heating moment of a first heating base body, corresponding to the first presetposition, of a printing head; determining an actual heating moment according to the current heating moment and the first time compensation value; and controlling the first heating base body to heat at the actual heating moment, and controlling the ratio of the position error to the second distance within a preset range. Therefore, the ratio of the position error of the image-text information to the second distance is controlled within a preset range, and the printing precision of the printer is improved.

Description

technical field [0001] The present invention generally relates to the field of thermal transfer printing, and more particularly relates to an error correction method for a thermal transfer printer and the thermal transfer printer. Background technique [0002] At present, thermal transfer printers have been widely used in various industries. Nowadays, thermal transfer printers are affected by the accuracy of the equipment, and there is a large deviation between the position of the printed part of the graphic information (including patterns and / or text) and the position of the part of the graphic information in the electronic document, and the printing quality is poor. . [0003] Therefore, it is necessary to provide an error correction method for a thermal transfer printer and the thermal transfer printer, so as to at least partially solve the above-mentioned problems. Contents of the invention [0004] A series of concepts in simplified form are introduced in the Summar...
