Definitions
- the present invention relates to a two-dimensional code in which black or other data cells are arranged in a matrix in a base cell such as white, so that either the base cell or the data cell is in a transparent state.
- the present invention relates to a mold two-dimensional code, an article to which the two-dimensional code is attached, a printing method and a display method of the two-dimensional code.
- Barcodes are widely used because they are fast and accurate, and barcodes representing information such as product management and manufacturing management are attached to various products.
- Such a barcode is a two-dimensional barcode that is a one-dimensional barcode in which information is arranged in one direction and a two-dimensional barcode in which information is arranged in two vertical and horizontal directions to increase the amount of information compared to a one-dimensional barcode.
- One-dimensional barcodes are attached to popular products that require less information than before.
- two-dimensional codes have the advantage of storing a large amount of information in a small space, and the recent development of mobile phones has made it easier for individuals to recognize and recognize them. It is used by being attached to information magazines, bumplets, or displayed on the screen. Examples of the stored information include text information and Internet address information.
- Two-dimensional codes include Code49 (Intermec (USA)), PDF417 (Symbol Technologies (USA)), VeriCode (VERITEC (USA)), DataMatrix (ID MA TRIX (USA)), QR Developed code (DENSO (Japan)) * Announced.
- Code 49, PDF417, etc. are codes in which conventional barcodes are stacked, and are called stacked two-dimensional codes.
- QR code, VeriCode, DataMatrix, etc. are codes that have the shape of a basic eye, and are called matrix type two-dimensional codes.
- the QR (Quick Response) code developed and announced by Denso Corporation is the most widely used two-dimensional code in Japan. (See Patent Document 1).
- QR code The smallest unit (black and white square) constituting a QR code is called a cell.
- a QR code is represented by a combination of cells, and a position detection pattern (cutout symbol), timing information, format information including information such as error correction level and mask number, data, and error correction code (Reed-Solomon code).
- the power is composed.
- QR code can be expressed in 1/30 space with the same amount of information compared to existing barcodes, and can be read from any 360 ° direction using three cut-out symbols. It has the characteristics.
- the cutout symbols are three (1 for micro QR) position detection patterns placed at the three corners of the QR code. First, by searching for this pattern, the position of the QR code can be recognized, enabling high-speed reading.
- QR code can recover and identify data even if 30% of the data area is dirty or missing.
- data for data restoration also prevents reading errors and has the effect of not outputting incorrect data.
- the two-dimensional code such as the above-mentioned QR code has a square shape in which white and black (or dark brown) cells are arranged in a matrix, it is used in information magazines and pamphlets.
- the code is embedded in the background image, there is a problem that the design is uncomfortable.
- the two-dimensional code has the color shape as described above, there is a problem that if the code is more noticeable than the display, which is the most noticed item such as a trademark or a headline with strong contrast. Furthermore, once a code is attached, it can be read at any time if there is a reader, etc., and there is a problem that the situation at the time of reading cannot be set, for example, it can be read only under any circumstances.

- base cells and data cells are arranged in a matrix, and one of the base cells and data cells is in a transparent state.
- the two-dimensional code reads the contrast between the black (brown) cell part and the white cell part and replaces it with a 0 or 1 signal for information.
- the two-dimensional code was developed.When it was announced, it could only be read when the contrast was high, such as black and white, but the contrast was low due to the recent advancement of image processing technology and readers, and the establishment of error correction technology. It is now possible to read even when there is a little dirt or defects.
- the present invention has been researched and developed to solve the display problems of the existing two-dimensional code using such background technology.
- the code can be embedded in the background image or the like without a sense of incongruity.
- it since it is embedded in an area such as a background image, it saves space and saves space.
- the color shown in the cell that is in the transparent state and the color of the cell that is not in the transparent state can be read only when the code recognition device has a readable contrast. Depending on the situation of the background part of the code, it can be set whether reading is possible.
