The understanding of ticket ink

Ink is a coloring material in the printing process. Its composition is similar to paints, paints, and paints in terms of manufacturing content; it is a colloid that is composed of particles and stretch material.

There are many kinds of inks, and there are various types of layouts such as letterpress, lithographic, gravure, and aperture printing inks. There are also refractive indexes such as clear ink and opaque ink. There are also special inks such as security ink or UV ink for ticket printing, and other special inks.

First, the structure of the ink

The ink is composed of pigment, extender and auxiliary agent. Before the preparation, the raw material formulation must be selected, and then the raw materials are mixed in a mixer or a stirrer according to the recipe sequence, and then put into a rolling machine to be divided into low-, medium-, high-speed and multiple-passages for different suitability. Processing, testing, can be loaded after the pass.

Second, the understanding of security ink

The safety ink is mainly used to print the ink on the ticket, in order to avoid duplication of copying, alteration and alteration, and to ensure the highest security of the ticket. Because it is closely related to the security of the ticket, it must have the following characteristics:

(I) Lightfastness ━ ​​When a ticket is used in circulation, it will not fade due to strong light or sunlight.

(b) Wear resistance so that tickets are not lost due to manual inventory or friction.

(C) heat resistance, so that the ticket surface is not produced due to heat.

(d) Water resistance ━ It has resistance to wetness in hot and cold water.

(5) Alcohol resistance The solvent resistance is such that the attempted counterfeiter cannot analyze the contents of the ink and it is difficult to copy.

(6) Chemical resistance ━ Good resistance to all chemicals, especially acidic agents, oxidants, reducing agents and bleaching agents.

(7) When using a color photocopier for photorefractive printing, the face color will automatically change color, making the photocopying effect different from the original ticket.

The ink used for printing cheques today has one more feature than the ones mentioned above. To make the cheque face difficult to alter, the cheque shading ink must be lightened immediately after being wiped by the eraser. When exposed to ultraviolet light, it can be seen that After the wiping reaction, the text will be destroyed if it is printed with small text as a background.

Based on the above features, we understand that ink plays a very important role in printing valuable tickets. However, in addition to ink, the security of tickets must also pay attention to clear, refined, legible, trustworthy images, extremely uniform color, paper, and print quality.

Third, security ink application range

The security ink application is quite extensive in ticket printing, including shading, images, numbers, passwords, dark lines, and the like.
