TB120 etching machine Xian Ju Dawn Machinery Factory

Also called "etching engraving," "copper engraved print," "loss of copper engraving," "corrosive print." Print kind. Edition refers to the metal corrosion or directly with the etching solution with a needle or a knife made of a kind of lithography prints. Belongs to gravure. Because of the more commonly used metal plates is a copperplate, it said. Plate-making method is based on anti-corrosion wax or preservatives (usually in yellow wax, rosin, pitch and other acid materials) coating sections, forming a layer of corrosion film, with carved pin in the layout on the painting, and then placed in etching solution (commonly used nitrate solution) in the corrosion. Those who are carved at the needle scrape corrosion film, he incurs corrosion, the formation of concave lines, corrosion longer, the more deeply concave lines. After the removal of anti-corrosion film version of the form. Coated with ink before printing layout, so that all concave lines filled with ink, and then Kaiqu concave line outside the ink, so that all concave lines filled with ink, and then Kaiqu concave line outside the ink on the copperplate press machine printing, paper cuts and concave in-line ink absorption on paper to form raised lines, because lines are thickness, depth, density, coupled with on-line outside the Kaiqu more or less ink on the formation of more than one level, the tone changes in a complex picture. In addition, the method can also use fly ash, soft wax etching into the other results. Can be directly used without corrosion carved pin in the layout engraving, known as "dry moment."
