Problems solved by technology

In the case of reducing the unit size by one dot, it is okay if the amount of ink bleeding is approximately the same size as one dot, but inkjet printers that often cause bleeding larger than the printing resolution are generally not available, so after printing Gaps are created between black cells (see Figure 9(c)), which can cause read errors

Embodiment Construction

[0030] Next, an embodiment embodying the present invention will be described. FIG. 1 is a configuration diagram schematically showing the configuration of an inkjet printer 20 according to an embodiment of the present invention, and FIG. 2 is a block diagram showing electrical connections of a print head 24 .

[0031] As shown in FIG. 1 , the inkjet printer 20 of this embodiment includes: a printing mechanism 21 that ejects ink droplets onto the recording paper S conveyed from the inside to the outside on the platen to perform printing; a paper feeding mechanism 31 , including the feed roller 35 driven by the drive motor 33; the cover 41 formed near the right end of the platen 44; the controller 70, which controls the inkjet printer 20 as a whole (equivalent to the control mechanism of the present invention).

[0032]The printing mechanism 21 is provided with: a carriage 22, which moves back and forth along the guide rail 28 by the carriage belt 32; ) and black (K) inks of ea...

Abstract

The invention provides a method of printing a two-dimensional code that a reader rarely reads error code. Ejecting ink to a black dot (84a) position from a nozzle to form a two-dimensional black cell (84) but not to a ink bleed adjusting portion (84b). At the moment, three directions of up, down, right and left of the ink bleed adjusting portion (84b) eject ink, the ink bleed adjusting portion (84b) is placed inside outermost of the ink ejecting area Ar. Ink is attached between recording paper S and drying, and has a tendency that bleeding to the ink bleed adjusting portion (84b) only. Namely, the ink bleed adjusting portion (84b) plays a role as a reservoir. As a result, ejected ink to black dot (84a) position inside outermost of the ink ejecting area Ar blacks the ink bleed adjusting portion, and almost not extend to exceed outermost of the ink ejecting area Ar.

Description

technical field [0001] The invention relates to a two-dimensional code printing method and an inkjet printer. Background technique [0002] Conventionally, two-dimensional codes that can handle information volumes several to several hundred times larger than barcodes have been known. As such two-dimensional codes, stack (stack) type and matrix type (matrix) type are known, wherein as stack type, there is PDF417, as matrix type, there are QR code (registered trademark of Denso-Wave Corporation), DataMatrix, Maxi Code wait. In addition, two-dimensional codes need to arrange multiple black or white cells in a moderate size. For example, it is recommended to arrange about 20 to 40 cells vertically and horizontally at a size of 2 cm corners for the size corresponding to reading by a mobile phone with a camera. In this case, the size of one cell is about comma-number mm. On the other hand, in the case of printing a two-dimensional code, for example, there are black cells at fo...
