Lithographic ink and mesh ink

What is a lithographic ink?

It is a generic name for various inks suitable for lithography. Lithographic ink is a general term for the printing plate type ink in which the pattern portion and the non-graphic portion are on the same plane. All parts of the lithographic printing plate are basically in a plane. The pattern is affixed with oil, and the non-graphic pattern is hydrophilic, and the principle of oil-water repulsion is used for printing. Therefore, the lithographic printing ink must have water resistance properties.

Second, the characteristics of lithographic ink (1) The color of the ink coloring force is higher. Since offset printing is indirect printing, the ink blots printed on printed products are very thin, and only a strong tinting strength can meet the requirements.
(2) Since the printing speed is faster and faster, the ink should have good flow properties and good drying properties.
(3) The ink should have good water resistance, so the water resistance of the pigment in the ink is very demanding. Most of the lake pigments are soluble in water and cause dinging. If the binder is hydrophilic emulsified, it will cause poor ink transfer and dryness, and the resin type binder is more resistant to water than the oil type binder.

Third, the type of lithographic ink

(1) Printed plate inks made using the principle of repelling oil and water, such as lithographic inks, flexographic printing inks, and stencil printing inks.
(2) Use other methods to make the ink not contact with water, and the ink is still printed by contacting a flat offset plate with the substrate, such as dry offset ink and waterless offset ink.
Fourth, the common lithographic ink 1, lithographic ink: suitable for lithography printing ink.
2. Offset printing ink: The general name of the ink applicable to various offset printing machines.
3, offset printing ink: imprinted with high gloss offset ink.
4. Offset resin ink: offset ink made of synthetic resin as the main raw material.
5. Offset web ink: Suitable for web offset printing inks.
6, Offset sheetfed ink: suitable for ink sheetfed offset press.
7, offset four-color ink: apply to four-color offset press or general offset press, using four-color printing process, yellow, magenta, blue, black complete sets of ink, printed color or color painting manuscript for use.
8, offset fast fixing ink: printed on the coating paper due to solvent infiltration so that the ink quickly solidified to touch non-stick offset ink.
9. Offset printing ink: It is suitable for tinplate printing, with quick-drying and strong adhesion.
10. Offset Steam Printing Ink for offset printing: refers to the offset printing ink that does not change color when printing and disinfecting and can not be discolored when it is printed and canned.
11. Minami printing ink: It is suitable for printing inks for calligraphy and other artworks used in the Feiluo printing press.

Mesh version ink

Also called silkscreen printing ink, it refers to the ink of various substrates suitable for various kinds of mesh printing. A type of ink that is printed on the printing surface through the aperture of the printing plate. Mesh version ink is divided into ink and screen printing ink.
