Optimally, the print thickness of ink is 10um.
In a specific example, the printing process of the gray scale Quick Response Code comprises the steps：
23% gray value is selected in the range of 20%～40%, two-dimension code image is made on computers；
Two-dimension code image is uploaded or stored to Mimaki UJF-3042 printing machines, and the printing machine is to two-dimension code image
Parsed, obtained corresponding half-tone information, and state of the printing machine in printing Quick Response Code is ready for；
Select chip base to be 300g art papers, be fixed on stamp pad with monochromatic black printing two-dimension code image, Dan Heiyin
Brushing CMYK (colored printing) is：C:0M:0Y:0K:23%, and printed using LH-100UV cured printing inks, obtain two dimension
Code, wherein, shower nozzle distance is 2mm, and the thickness of printing-ink is 10um；
The recognition effect of Quick Response Code is detected using smart machine (such as smart mobile phone), and light splitting Density Measuring Instrument can be passed through
The half-tone information of measurement Quick Response Code, to facilitate the adjustment to gray value, specific debugging step can be according to above-mentioned embodiment party
The step of formula, thus, the printing of batch gray scale Quick Response Code can be completed, the consumption of ink can be greatly reduced, at the same have compared with
The effect of good recognition speed.Fig. 2 is refer to, the gray value of the Quick Response Code 2 on packing box 1 is significantly less than the two dimension of prior art
Code, by reducing quantity of ink, can also reduce the low effect of printing cost.
