Description
Technical field
The present invention relates to a kind of printing mechanisms for specific character, more particularly, to a kind of print generated for two dimensional code
The recognition methods of brush mechanism and two dimensional code.
Background technique
Planar bar code technology is newest barcode technology, is the collection letter to grow up on the basis of bar code technology
The technologies such as coding, information transmitting, image procossing, data encryption are ceased in the integrated technology of one.Two dimensional code can be in length and breadth two
A direction storage information, substantially increases storage density.If the QR for the use of the one-dimension code under standard state being M with error-correction level
Two dimensional code compares, and information represented by two dimensional code is about more than 80 times of one-dimension code under same area.
With the lasting rapid development of mobile Internet, the application of two dimensional code can be more and more extensive, and to planar bar code technology
Research also can increasingly go deep into, planar bar code technology will also make planar bar code technology to deeper wider array of side with merging for other technologies
To development.Because of the manufacturing process of its low cost, efficient propagation efficiency also makes it be increasingly becoming numerous enterprises and moulds itself brand
The important channel of cognition degree.Either with the use in conjunction of APP, wechat platform either in any load for carrying two dimensional code
On body, two dimensional code all plays key player in the application field that convenient and efficient propagates information.Businessman can be for its user's
" barcode scanning " information is arranged, and data analysis is completed, and to production from now on, packaging, the processes such as marketing carry out precise positioning, full
Sufficient customer demand, improves customer loyalty, and extending user quantity completes Brand Marketing.
For conventional matrix two-dimensional code as shown in Figure 1, being made of the form of matrix, the length of each module is identical as width,
Module and entire symbol usually all occur in the form of square, and rectangular space passes through the different distributions of black and white symbol in a matrix
It is encoded.Matrix two-dimensional code is a kind of graphical symbol automatic identification processing code system, is usually constructed with error correction.With representative
The matrix two-dimensional code of property has DM code, QR code, Chinese letter co etc..
Other than the two dimensional code on electronic equipment, the two dimensional code under line is printed in product packaging, shelf, commodity transaction
People's lives are given in sales counter, antifalsification label, the positions such as parking lot, anti-fake for identifying product, bank settlement, commodity transaction etc.
It provides convenience.For many two dimensional codes, it is printed in transparent material, due to the influence of the light transmittance of transparent material, leads to its sky
The reflectivity of white symbol is low, to make the two dimensional code discrimination printed reduction.It is existing in order to avoid the influence of transparent material
The Normal practice of technology is first to carry out unit dark and light in image in 2 D code before printing two dimensional code on transparent material
Reversion, however printed in the dark unit that reversion generates using light color inks, to increase two dimensional code on transparent material
The blank symbol of pattern and the reflection differences of printing symbol, improve two dimensional code discrimination.However, transparent material is frequently used for product
Packaging, if the packing material of transparent material is light-coloured prods, transmiting its blank symbol light can be reflected by light-coloured prods, from
And increase the reflectivity of blank symbol, reduce blank symbol and print the reflection differences of symbol, cause two dimensional code identification can not
Identification.
To solve the above-mentioned problems, application No. is the patents of invention of CN201710125664.4 to propose a kind of two dimensional code life
At system and recognition methods, by printing standard two-dimensional code image and reversion image in 2 D code in transparent material surface, together
When indicating bit is set, the background material of transparent material is determined according to the reflectivity of indicating bit, according to the property of background material determine
Criterion of identification image in 2 D code or reversion image in 2 D code are the transparent material two dimensional code of light color hence for background material
It can accurately identify.But in this method, need to be arranged indicating bit, while needing to print standard picture and reverse image.
Summary of the invention
