Some special ink printing techniques

Author:  Source:   Update:2015-05-18  Counting:540

Metallic ink is made of tiny metal sheet manufacturing. When the ink dry, these flakes in print surface form a layer of pressed metal foil. When the metal pigment to form a thin layer in the printing surface, gold or silver ink layer will have a higher gloss. If change of color ink ink Beanies component or additive, will make the gold ink color range in reddish gold to gold change between.

Tips: if you want to get the best effect and advocates using a metal plate, and is not a static plate, which can avoid the fountain solution including an excess of glycerol or ethylene glycol, due to the evaporation of the liquid medium will slow down the drying speed.

When light conditions, light-emitting fluorescent ink. Occurrence of this effect the key lies in the ink includes special colorful pigment, it can absorb ultraviolet energy and this energy is converted into longer visible color wavelength. Print appearance can emit strong contrast full color, so as to attract people's attention. A particlefluorescent ink than other oil-based ink particles or more soft rubber base. But this does not affect the function of it, because they are in the cylinder and the cylinder, a printing plate to the handling process of rubber blanket, blanket to the substrate, with common methods of handling.

Tips: the most suitable metal plate using fluorescent ink. Selection of paper best don't have to have a lighter or colorful paper, with the colour of the paper cuts, and will make the ink Mingdu is reduced to a minimum. Partial white or partial bright paper will strengthen the fluorescence effect. Compared with non ideal fluorescent inkcoated paper with high brightness and ink absorption of the good. Coated paper has nicer effect.

Traditional fast drying ink is very suitable for paper of positive print, but the same ink on recycled paper when printing tend to appear problem, especially less inking. This is because the light ink will make the ink rollers onthe moment than to stay in the thick ink or print large appearance for a long time. When the ink for deposited onpaper, ink rollers have lost the solvent, adding viscosity trend. This high viscosity will pull the recycled paperweak fiber, affect the normal print.

Tips: vegetable oil ink than solvent based inks have low viscosity. They also have the high ratio of solvent ink is very good stability of the roller and the characteristics of the in all the printing process adhere to the lower viscosity. The ink stability in slow printing costs can be expressed also means in the print copy needs longer time. But this print on the recovery of recycled paper to achieve high quality is a reasonable sale.

No special fluorescent ink fountain solution, but the alcohol fountain solution on metal plate effect. Fluorescent ink printing needs a large amount of ink. In fountain solution has always been to participate in 20% alcohol to get better density value, such a mixture can be promised to have a lot of water evaporation. The oil is heavy. Instead of ink and ink balance temperature balance in the anhydrous printing process, so do not need to add fountain solution.

Tips: in general less than an ounce of pure ammonia in a gallon in fountain solution, the buffer pH value increased.
