How to choose screen printing materials in Open Type Rotary Screen Printing Machine?


  1. Stretch the net

The aluminum alloy screen frame is usually stretched by a pneumatic stretcher to ensure the tension of the screen. In order to achieve good printing quality, the tension of the screen must be evenly divergent. If the tension is too high, the screen will be damaged and cannot be printed; if the tension is too low, the printing quality will be low and the overprinting will be inaccurate. The tension of the screen depends on the screen printing pressure, printing accuracy and the stretch resistance of the screen.

  1. Wire mesh

The wire mesh is divided into polyester wire mesh, nylon wire mesh and stainless steel wire mesh, and is further divided into multi-wire mesh and monofilament wire mesh. Depends on the accuracy of the printed product pattern, the quality of the printed product and the customer's requirements, usually, precision products use monofilament screens.

  1. Screen frame

Generally speaking, the screen frames used in screen printing packaging are mostly aluminum alloy frames. Aluminum frames are highly praised by users for their tensile resistance, high strength, good quality, light weight, and convenient use. The size and material of the screen frame play an important role in the quality of the screen.

  1. Ink

The physical properties of Flat Screen Printer printing inks mainly include density, fineness, fluidity and light fastness, etc., which have a great influence on the quality and special effects of printed matter. If the density is moderate, the fineness meets the requirements, the fluidity of the dispensed ink is ideal, and the light resistance is good, and the product can be printed to achieve the desired effect. Inks are divided into solvent-based inks (naturally dry) and UV light-curable inks. The matching ink should be selected according to the requirements of the equipment and printing method.
