Coating knowledge: factors influencing the effect of metal ink

Core tip: designers often choose metallic colors other than gold and silver Most of the printer will use metal ink and four-color or other spot color ink to adjust the ink of the metal spot color, but the metal materials used to produce the metal ink are relatively soft and thin metal sheets, and many printing operators are accustomed to using some metal tools with hard edges to mix the ink, while the metal materials are very sensitive to the shear force, too high shear force will cause metal pigment In order to avoid the influence of shearing force on metal pigment particles, we should use some flat ink when adjusting metal spot color ink Paint agent, top 10 Chinese wall paint brands Recommended introduction: interior wall paint and exterior wall paint can achieve beautiful, clean and pleasant effects, but the effects in different environments are different, so the color of the paint will be different There are ten brands of Chinese paint, ten brands of global paint, ten brands of Chinese wall paint, and ten brands of Chinese paint, Famous trademark of Chinese paint and coating In private rooms, most of us choose according to our own personality, personal hobbies and living habits The younger generation will choose the interior wall paint with rich colors and bright colors, while the older ones will have some working experience Paint Home News: designers often choose metal colors other than gold and silver Most of the printer will use metal ink and four-color or other spot color ink to adjust the ink of the metal spot color, but the metal materials used to produce the metal ink are relatively soft and thin metal sheets, and many printing operators are accustomed to using some metal tools with hard edges to mix the ink, while the metal materials are very sensitive to the shear force, too high shear force will cause metal Pigment particles deform or form many fine particles In order to avoid the influence of shearing force on metal pigment particles, some smooth tools should be used when adjusting metal spot color ink, and high-speed mixing should be avoided at the same time, otherwise the ink will lose luster In addition, the ink medium (such as resin and solvent) used by the general ink factory in making metal spot color ink is different from the metal ink already made In addition, as mentioned above, the equipment used in mixing metal spot color ink is also different from that used in making ordinary ink Therefore, if it is necessary to deal with a large number of packaging and printing, it can be obtained by directly ordering metal spot color ink from the ink factory Better results Because the materials used to make metal ink are all active metal materials, the chemical properties of metal ink are also very unstable When using and storing, they should also be strictly sealed to avoid absorbing too much water and being directly exposed to light for a long time In lithography, the use of inappropriate fountain solution will also affect its shiny effect In addition, the density of the metal pigment is large, so compared with the ordinary ink, the pigment particles of the metal ink are very easy to precipitate If the metal ink is not fully stirred before use, and the bottom of the ink barrel is not checked for sediment before printing on the machine, the color phase and glossiness of the printed matter are greatly different In the printing process, the viscosity of metal ink will gradually increase with the continuous volatilization of solvent In order to ensure the stable and good fluidity and transferability of metal ink, it is necessary to measure the viscosity of ink regularly and add solvent appropriately to keep the viscosity of ink in a stable state Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
