Problems solved by technology

[0004] The disadvantage of this method is that the substrate may be fast-moving, inaccessible and / or expensive (meaning very high cost of rejected samples)
Additionally, failure to adequately test print quality will result in images that are not printed to the required standard (for example, images may contain unreadable barcodes) leading to recalls of packaged products

Embodiment Construction

[0032] refer to figure 1 and figure 2 , shows a part of the printing apparatus 10 . Printing device 10 includes a printhead 12 that includes a plurality of printing elements 14 . The printing elements 14 are arranged in a line adjacent to each other. The printhead 12 has a first end 12a and a second end 12b.

[0033] The printing device 10 also includes a mechanism 15 for advancing a strip 16 carrying an imprinting medium (eg, wax-based ink) relative to the printhead 12 . The direction of movement of the strip 16 relative to the printhead 12 is substantially transverse to the direction of the line of printing elements 14 extending along the printhead. The printing device 10 also includes a mechanism 17 for advancing the substrate 18 relative to the printhead 12 (again in a direction substantially transverse to the direction of the line of printing elements 14 extending along the printhead 12).

[0034] As such, printhead 12 is capable of printing pixels at multiple locat...

Abstract

The invention describes a method of printing comprising: testing the condition of a printhead (12) having a plurality of printing elements (14), each of which is operable to imprint a medium Transferring from the strip (16) to the substrate (18), wherein the method includes testing the condition of each printing element (14); providing a preview of the image (30) to be printed; In the event of a number of damaged printing elements (14a, 14b) being disqualified relative to the image (30) to be printed, adjusting the components (30a, 30b) of the image (30) relative to the printhead ( 12) Position to improve print quality.

Description

technical field [0001] The invention relates to a printing device and a printing method for printing on a substrate. More particularly, the present invention relates to a printing device using a printing tape comprising a strip carrying imprinted medium, a printhead for removing the imprinted medium from selected areas on the strip, a printhead, To transfer blotting media to a substrate to form an image (such as a picture, text, or barcode). [0002] In particular, but not exclusively, the present invention relates to so-called thermal transfer printing devices in which a printhead is provided comprising a plurality of thermal printing elements which can be selectively energized so as to print The pixels of the media are softened and removed from the strip, and these pixels are transferred to the substrate. The printing elements are arranged in a line extending substantially transverse to the direction of movement of the substrate relative to the printhead and substantially ...
