Embodiment

[0045] The anti-counterfeiting special printing ink of the present invention can be in accordance with the following composition ratio:

[0046] 1.2-Hexanediol: 12g,

[0047] N-butanol: 2.5g,

[0048] DH-1: 6g,

[0049] EDTA: 0.2g,

[0050] MS-1: 0.3g,

[0051] Water: balance.

[0052] The manufacturing steps are:

[0053] a. Dissolve the dye with a little water;

[0054] b. Add to the mixed solution of 1.2-hexanediol and n-butanol that has been prepared quantitatively, and add dropwise to the MS-1 solution and the prepared EDTA solution of a certain concentration and stir for 30-50 minutes;

[0055] c. Add the remaining amount of water and stir for 20-40 minutes;

[0056] d. Let stand for 1 hour to discharge; and

[0057] e. Put the ink into the print cartridge for later use.

Abstract

The invention is about a method of marking ink which is only used to defend fake. The composition of it is: lipidol or lipid, surface active agent, integration agent, water, buffering agent. Their mass percents are: 1,2-hexylene glycol: 5%-15%, butanol: 1-5%, DH-1: 5-10%, EDTA: 0.1-0.5%, MS-1: 0.1-1%, water: the rest. The process is: a. dissolving the colorant in water, b. put the correct percent of 1,2-hexylene glycol and butanol into the solvent, then dropping the MS-1 and EDTA solution when mixing the solvent for 30-50 min, c. put the rest precent of water into the printing ink box. The picture and word would be shown red fluorescence in the UV but blank in the usual light.

Description

Technical field [0001] The invention relates to a printing ink and a manufacturing method thereof, in particular to an anti-counterfeiting special printing ink and a manufacturing method thereof. Background technique [0002] Inkjet printer technology is a printing technology that does not require a printing plate. It is a computer-controlled print head that directly sprays ink on top of the paper to form graphics. There are two current inkjet printing technologies: a thermal foaming technology and a micro-piezoelectric technology. At present, the ink market that matches inkjet printers in China is mainly controlled by three large foreign companies: HP, Canon and Epson. But the special printing ink that can print invisible two-dimensional barcodes has not been seen in the market. [0003] The basic performance requirements for inkjet inks for printing should be: clear images, good water resistance, light resistance, acid and alkali resistance, and the same requirements for invisi...
