Mirror silver ink use tips

Mirror silver ink The substrate used by mirror silver ink is mainly several kinds of transparent sheet, and it is not printed (reverse), and the positive role is seen. The materials used are: PC(polycarbonate), PMMA (acrylic or plexiglass), hard PVC(polyvinyl chloride) and treated PET (polyester). Mirror ink has adhesion to the above transparent sheet, and can obtain mirror and mirror discoloration. However, it is worth noting that in PC or PMMA products, because of the difference in materials and processing technology, some will not get a good mirror or mirror change due to poor solvent resistance, so it is necessary to do sample experiments before use, and it can be produced after admitting. In addition, to get the mirror effect, in addition to the above, because the mirror silver ink is composed of special aluminum powder pigments and a small number of resins and other basic materials, and vacuum electroplating silver is a sheet layout, parallel placement on the surface to get the function of mirror reflection, so the surface of the poor smoothness of the data (substrate) and the solvent in the ink is not good mirror effect. (1) In addition to a few resin and flake aluminum powder pigments in mirror silver ink, the solvent accounts for more in mirror ink, so the viscosity of mirror ink is very low, and the skew open screen plate is not used as much as possible when screen printing, otherwise the activity is more fierce, so regardless of the technology is still machine printing, parallel lifting screen plate should be used. So that the thin water ink has been covered in the screen plate, to avoid or reduce the impact of blocking the screen printing normal progress. The traditional method used to make the ink is thinner, and now the mirror ink produced by Color Butterfly Technology's mirror silver J2107-A and the supporting J-40 resin has a very good effect on the consistency, brightness, metallic feeling, prinability and mesh function and will not be active. (2) When the mirror silver ink is printed on the screen printing machine, the metal reinking scraper should be changed to the rubber reinking scraper, so that the ink is evenly coated on the screen plate. The scale of the coating on the net is controlled as much as possible in the size of the printing area close to the useful text, otherwise, due to the large coating area, the solvent in the mirror ink is quickly protected and the blocking network can not be connected to the printing. (3) Mirror silver ink Mirror ink solvent evaporates quickly on the net, in order to avoid blocking the net, it is necessary to do continuous printing together screen printing should also pay attention to not let the active air make the screen boring. There is a very good way to deal with the questions about solvent evaporation generally reported by the industry. (4) The thickness of the ink film is too thick, and the ink aluminum pigment is stripped of appearances, so it is advocated that the ink be printed as thin as possible, and pay attention to the mirror ink can not be stacked. (5) Mirror silver ink mirror ink itself does not have a good concealment function, in order to get a good mirror and its mirror discoloration, it is necessary to print a layer of concealment ink, this printing ink should be used for mirror and discoloration mirror ink adhesion without solvent corrosion ink. Mirror ink is a high-grade, decorative ink, thin like water, and it is easy to evaporate in screen printing, if the printing environment is not good, printing technology is not in place, so in the printing will show the addition of the number of blocking and wiping screen, together with the formation of the ink layer on the substrate uneven appearance. Gravure mirror ink printing tips (1) gravure mirror ink printing is not different from other gravure inks, but because of its high price, do not pay attention to the use of greater waste, so you must do a pre-press test before printing. (2) In the printing process, pay attention to the adjustment of ink viscosity, the rich country is not used up, and it is necessary to ensure that the ink is not contaminated when recovering the ink.
