Metallic inks are made up of fine metal foils (aluminum foils are used for silver ink and copper foils are used for gold ink). When the ink dries, these foils form a layer of molded metal foil on the surface of the print. When the metal pigment forms a thin layer on the surface of the printed product, it will produce a higher gloss of the gold or silver ink layer. If you change the metal foil composition of the ink or the additive of the tinted ink, the color range of the golden ink will change from reddish gold to golden yellow.
Metal gold or silver inks have a longer shelf life and will not lose gloss even if stored in a container for one year. However, the metal ink in the PANTONE Metal Color Manual is not very stable, and should be used as soon as possible after it is purchased or prepared. When formulating metal ink, softer particles are used. Therefore, the metal foil in the ink can form a thin metal foil, or spread as much as possible on the surface of a single printing material to obtain maximum gloss. Metallic ink has the characteristics of low viscosity, suitable for transfer between ink rollers, making the printing process cleaner.
Coated paper absorbs fixed ink better, so the gloss of the ink printed on it is most vivid. Smooth uncoated paper will also get better results, but the gloss is slightly reduced. The rough-surfaced paper prevents fine metal ink particles from forming metal foil on the paper surface, thus reducing the printing effect of metal ink.
Some substrates, especially polish-coated and clay-coated pond porcelain products, because they do not have sufficient adhesion to firmly hold the ink on the surface of the substrate, they often only absorb the ink adjustment ink in the ink and use metal pigments. Particles stay on the surface. This phenomenon, called "pulverization", causes metal colors to peel off the surface of the substrate. In order to prevent the occurrence of "pulverization", the amount of water should be set to the minimum, because ink with higher water saturation is more prone to "pulverization". When printing on the surface of high-coated paper or Porcelain, an appropriate amount of desiccant should be added to the ink. Before printing with gold or silver ink, the surface of the substrate is usually sealed with a conventional oil-based transparent white ink coated with gum. If "pulverization" has occurred, printing another layer of ink on the surface of the first layer will often make up for this error. Adding printing ink can also overcome powdering, but this will often reduce the gloss of the metal.
Tip: For best results, it is recommended to use a metal plate instead of an electrostatic plate, which can avoid the fountain solution contains excessive glycerin or ethylene glycol, because these non-volatile liquid medium will slow down the drying speed.
The opacity of metallic ink will cause the operator to compensate for too much ink, making the ink unbalanced. This situation should be avoided as much as possible, because it will bring too much burden to the dampening system, which leads to paste (the ink particles are emulsified in the fountain solution) and dirty (the ink adheres to the non-graphic text section). Even experienced printers need to use too much ink to achieve the most perfect metal effect. The best way to prevent these failures is to add ink to a lighter-colored image so that it just covers the image. Then, increase the amount of ink, and adjust the water supply to make it slightly higher than the minimum value, so as to avoid non-graphic parts of the ink. During the drying process, a thin layer of metal will stand out, providing a brighter gloss.
