Special printing
If one has exclusively a set of advanced computer typesetting，printing equipment and raw material or some special processes with high confidential, then the anti-counterfeit printing technology can play a better role in anti-counterfeiting. Meanwhile, integrated with the security graphical pattern design, the technical threshold will be set much higher for counterfeiters.

Latent image
Latent image is the graphical context information hidden in the security lines at a certain position which can be seen at a certain view angle.
Latent image can only be printed using engraved intaglio forming. It can prevent counterfeits such as copying and offset printing. Since the horizontal intaglio formed line and the vertical intaglio formed line need different view angle, it print two graphical contexts at the same part of the paper with intaglio formed lines of different directions.
For example, we can seen the “100” number hidden in the 100-yuan banknote if we view it with our eyes almost at the same height as the flower pattern in the banknote
Pattern splicing
It is a technology used for shading printing and has two different forms. One form is full size motif printing. When a printed work is cut to specified size, the original shading motif at the cutting shoulder is broken. But if we splice the two cutting shoulders, a complete shading motif will appear again. The other form is printing cut edge marks at the four edges of the printed work. If we fold these marks to the face side, the mark lines will engage completely.
For example, the technology is used in the shading pattern at both sides (front side and back side) of the 100-yuan banknote.

Micro-printing
With special printmaking technology, the characters are reduced to invisible tiny and then printed. These characters can be viewed under microscope. Either the offset printing or the intaglio form can be used for micro-printing. Both methods are frequently used. Due to resolution restrictions, photo copier and scanner can not duplicate these micro-printed characters.

Rainbow printing
Rainbow printing is also called cross-color printing. It is used for anti-counterfeit shading printing. The shading line printed at one time may have several different colors. So, different parts of the whole pattern may have different colors. At the place where two different colors join, the transition from one color to another is smooth and natural, just like the rainbow.
Rainbow printing is used for shading printing in all fifth edition banknotes. The anti-counterfeit function is outstanding.
