The basic skills and the use of screen printing Ink’s color adjustment

The basic skills and the use of screen printing Ink’s color adjustment




Screen printing workers must adjust used ink by following below steps:

a. To understand all kinds of specification and performance of Ink, which makes it meet with production need.
b. Have a good command of basic knowledge of color, be skillful during ink handling.
c. Analysis of color adjustment and process skill of printing,Identify color of color sequence, In order to avoid incorrect color sequence, both miscible and color change.
d. Pay more attention to Ink’s color intensity when ink adjustment.

Adjusting by the original color as much as possible if the required Ink’s intensity is larger. Otherwise it becomes grey easily, then it cuts down the Ink’s original intensity.

Appropriately printing adjustment of Ink
Viscosity of factory ink usually is slightly large, user should make comprehensive adjustments for ink viscosity, surface tension,fluidity and drying speed according to the characteristics of printing graphics, screen mesh, printing speed,workshop temperature, Substrate’s surface tension and ceiling inking performance, Proper Solvent, diluent, surface active and viscosity reducing agent are very good options in this case.

For example,you should get slightly smaller fluidity and lower drying speed Ink when printing thin line or dots.you should use larger viscosity and higher drying speed Ink when printing thick mesh. Fluidity can be slightly larger and drying speed also can be higher when printing in high speed. Drying speed should be lower and viscosity should be slightly larger when the temperature in workshop is too high. Ink’s surface tension should be smaller when Substrate’s surface tension is small. Ink’s fluidity and surface tension should be larger, and drying speed should be lower when Substrate’s surface ceiling ink performance is in very good condition.

Printing Plate's graphic printing precision includes the following two factors: The first is that the line distortion extent of graphic printing should be less, the line width accuracy is about ±0.05mm; secondly the graphic’s printing position accuracy is required to be high, the length within 500mm for graphics, the position deviation < + 0.15mm, there are many factors that influence the two aspects of accuracy, With the graphics printing producing process from the screen plate had been made, the main factors are the following:
1 Screen plate material and printing material selection: including screen frame material, screen mesh quality, material, color and ink performance;
2 screen printing equipment, tooling: screen printing machine, positioning tooling;
3 production process: including stretching, plate made by silk screen, printing process etc.
4. Working conditions: work site temperature, humidity, cleanliness, especially cleanliness is one of the important factors to influence the quality of the products;
5. People is the most important factor to affect the quality of the project, the operator must have a high sense of responsibility and high technical quality.
