What are the requirements and skills of the stretch screen of Polyester Screen Printing mesh?

Polyester screen printing mesh refers to the use of wire mesh as a screen. Then, the ink is printed through the ink through the hole to print a pattern or a letter. It is composed of five basic elements. Screen plates, inks, printing stations and substrates. Its composition is the five major elements. Then when using it, the stretcher needs a skill and attention.

Stretching technique of Polyester Screen Printing mesh

The screen printing mesh stretcher is actually a measurement of the tension of the screen based on these parameters. When measuring the tension, the tension point to be inspected should be 10 cm from the margin in the frame. Otherwise the tension that appears is not very accurate.

Learn about the tension of Polyester Screen Printing mesh. The unit of tension: Newtons/cm (N/CM), which can be measured with a Newtonian tensiometer. The tensiometer measures the tension in the warp and weft directions. The so-called warp direction tension of the screen is the tension in the winding direction of the whole roll, that is, the tension in the direction of the edge typing; the weft tension of the screen is the tension in the width direction of the screen.

Different web templates are different for the size of the tension. Manual printing, rough printing products, or for precision, size, etc., tension > 6N / CM, it is worth noting that when color block printing, in order to make the overprinting position accurate, not only the screen tension should be greater than 10N / CM, Moreover, several sets of overprinted plates must reach the same tension, which is more important for dot printing, otherwise it will cause deviations of moiré and hue.

Dot printing generally requires a higher tension mesh version. This is because when the tension of the screen stencil is low, the ink is uneven and the dot is enlarged and deformed, which affects the hue.
