Description

A two-dimensional code printing system and two-dimensional code generation method

technical field

The present invention relates to a printing device, in particular to a printing system and printing method for special characters such as two-dimensional codes.

Background technique

Bar code technology is an automatic identification technology that integrates coding, printing, data collection and processing. It also has the advantages of large information capacity, high reliability, various forms of data, and strong security and anti-counterfeiting.

With the rapid development of economy and information communication technology, the application of bar code technology has been involved in commodity circulation, transportation, industrial control and other fields. Traditional one-dimensional barcodes can no longer meet new requirements in terms of data storage capacity, reliability, confidentiality and anti-counterfeiting, so two-dimensional barcodes are increasingly valued and applied in more and more fields. With the promotion and application of two-dimensional barcodes, new requirements have been put forward for the generation tool of two-dimensional barcodes - two-dimensional barcode printers.

The development of printing technology is changing with each passing day, and there are many types of printers. According to the working mode of the print head, it can be divided into impact type and non-impact type printers. The impact type is represented by dot matrix printers, and its mechanical structure is relatively simple compared with other printers; the non-impact type mainly includes inkjet printing and laser printing. At present, most of the devices for printing two-dimensional codes use non-impact laser or inkjet printers.

QR two-dimensional code is a matrix two-dimensional code symbol developed by Denso Corporation of Japan in September 1994. QR is the earliest two-dimensional code that can encode Chinese characters, and it is also the most widely used two-dimensional code at present, and it is also a representative member of the two-dimensional code family. A two-dimensional code is densely set with multiple code elements in a small graphic range, for example, the number of horizontal and vertical code elements of a QR two-dimensional code can range from 21 to 177 code elements.

For QR codes printed by inkjet printers, ink tends to bleed into the vicinity during printing. For the code elements of densely distributed two-dimensional codes, the volume of the white units surrounded by black units is infiltrated by the ink of the surrounding black units, resulting in a reduction in volume, which may cause errors in the recognition of the printed two-dimensional codes. In order to solve the above problems, the conventional method in the prior art is to reduce the amount of ink at the border of the black unit or set an adjustment area at the border of the black unit when printing the surrounding black units for the white unit surrounded by black units. However, this requires precise control of the inkjet head during printing, which has high requirements for the printer; meanwhile, due to the different permeability of different printing papers, the printing effect of the above method for different printing papers will be different.
