How To Select Ink Using A Flat Screen Printer


   The ink used in flat screen printer is the same as other types of inks, which are ground with a mixture of pigments, resins, solvents, and additives. Let's follow us to find out how to choose the ink for this device.

  1. According to the drying method can be divided into.

  Evaporation drying type--Method of adhesion of ink film by evaporation of the solvent.

  Oxidation polymerization -- Ink film adhesion method by an oxidation reaction.

  Two-liquid reaction type -- By two-component chemical reaction to make the ink films adhesion method.

  Ultraviolet curing type -- chemical reaction caused by ultraviolet light irradiation causes the ink to form a film and adhere.

  Different drying methods of ink can bring different gloss after printing ink film, different resistance (mechanical resistance, chemical resistance, weather resistance), the use of different drying equipment, resulting in different costs, so users need to choose carefully.

  2. According to the type of ink, linkage material can also be divided into many types, but different ink manufacturers use different resins, can be divided into Epoxy resin, polyurethane, polyester, vinyl, acrylics, rubber and so on. Only if the material of the substrate is clear, different types of inks can be used to avoid bad adhesion caused by wrong inks. Not clear material of the substrate, it is best through the printing test, only after determining the choice of ink.

  3. Different types of inks using their manufacturers to provide supporting thinners, mainly because of a variety of thinners for a variety of different resin types of inks Different solubility to avoid undesirable printing results.
