Problems solved by technology

Bills are generally packaged in rolls, and they need to be unfolded for anti-counterfeiting printing. The unfolded bills tend to be bent under the action of stress, which affects the quality of printing in an uneven state, and easily causes overlapping printing content and skewed printing patterns. Affects the quality of bills. At the same time, this printing method cannot be printed continuously and the work efficiency is low.
In addition, the printed bills are mostly dried naturally, which takes a long time and affects the progress of subsequent rolls

Embodiment 1

[0027] A method of anti-counterfeiting printing. The ink used in the printing machine is ultraviolet-induced color-changing anti-counterfeiting ink, and its components include: 35 parts of epoxy resin, 10 parts of phenolic resin, 12 parts of ultraviolet fluorescent powder, 6 parts of dispersant, and 4 parts of defoaming agent , 8 parts of calcium carbonate, 13 parts of ethyl acetate, 12 parts of Virahol; The preparation method of anti-counterfeiting printing ink comprises the following steps: a) weighing, the proportioning weighing material of each composition described in claim 2 is standby; b ) stirring, stirring epoxy resin, phenolic resin, ethyl acetate and isopropanol evenly, stirring at 500r / min for 40min; c) tempering, adding ultraviolet fluorescent powder, dispersant, defoamer, calcium carbonate b) Stir the obtained material for 50 min at 1000 r / min to obtain the finished ink.

Embodiment 2

[0029] Method step is the same as embodiment 1, and different processing parameters are as follows:

[0030] 40 parts of epoxy resin, 15 parts of phenolic resin, 15 parts of ultraviolet fluorescent powder, 8 parts of dispersant, 5 parts of defoamer, 10 parts of calcium carbonate, 15 parts of ethyl acetate, 15 parts of isopropanol;

Embodiment 3

[0032] Method step is the same as embodiment 1, and different processing parameters are as follows:

[0033] 30 parts of epoxy resin, 5 parts of phenolic resin, 8 parts of ultraviolet fluorescent powder, 3 parts of dispersant, 2 parts of defoamer, 4 parts of calcium carbonate, 10 parts of ethyl acetate, 8 parts of isopropanol;

[0034]The printing table 1 is provided with a positioning block 5, which fixes the position of the printing paper 3 and improves the printing accuracy of the printing machine. At the same time, the fixing block 5 cooperates with the first pressure roller 4 to make the printing paper 3 more flat without curling , to improve the printing quality; the right side of the printing machine 6 is provided with a photoelectric sensor 7, which can effectively obtain the transmission speed of the printing paper 3, and then by adjusting the speed of the driving motor connected to the paper feed roller 2 and the roll roller 11, it can avoid the The excessive speed o...

Description

technical field [0001] The invention relates to the technical field of bill printing, in particular to an anti-counterfeit printing device and method. Background technique [0002] When printing bills, anti-counterfeiting printing is mainly to spray ink directly on the relevant areas of the bills to be printed, wait for the handwriting to dry after spraying codes, and then put away the bills. Bills are generally packaged in rolls, and they need to be unfolded for anti-counterfeiting printing. The unfolded bills tend to be bent under the action of stress, which affects the quality of printing in an uneven state, and easily causes overlapping printing content and skewed printing patterns. It affects the quality of bills, and at the same time, this printing method cannot be printed continuously, and the work efficiency is low. In addition, the printed bills are mostly dried naturally, which takes a long time and affects the progress of subsequent rolls. Contents of the inven...
