Corrosion method (medicine): The copper plate adopts the deep corrosion method to make the bronzing plate. There is a special powder-free corrosion machine and corrosive liquid (ferric chloride liquid + hydrochloric acid + anti-side corrosion agent) on the market. The corrosion depth is generally 0 ．5～0.6mm is better. Now some people use electrolytic etching machine to make hot stamping plate, and the effect is also good.

Production process: black and white manuscript design ~ black and white manuscript or film copy (flip) ~ gluing ~ printing ~ revision ~ corrosion hot stamping ~ embossing processing ~ full page

(Details) The combination of bronzing and embossing is to combine the yin and yang of the bronzing area pattern and the embossed part of the pattern into an organic whole film base. The plate is processed by a special process, and is exposed and corroded to make a bronzing, embossed and embossed plate. .The part that is required to be convex in the finished product, while the zinc plate is concave, and the part that is required to be concave in the finished product, is convex. Now the process is introduced as follows:

Hot stamping, embossing and embossing of the negative film: According to the design requirements, the photographer first pastes the yin and yang cross gauge lines on the drawn manuscript and then shoots it into a negative image① and then copies, develops, and fixes the negative image ① to obtain a positive image②, and then still Copy from the negative image ①, the exposure time is several times longer than the normal exposure time of the positive image ②. After developing and fixing, a positive image with a thicker outline is obtained, and then the positive image ③ is blurred with black ink. Fill in the outline, and after the positive image ③ is dry, use it to copy, and copy out the transparent negative image ④ with less exposure and more development. At this time, the positive image ② and the negative image ④ are combined, that is, the two films are combined. After the yin and yang cross lines are overlapped and combined, they are glued firmly with adhesive tape, and they are directly used for printing to corrode to make hot stamping and embossing plates. It is also possible to copy the combined film to obtain a well-defined positive image ⑤ Then the positive image ⑤ is exposed to corrosion to make a hot stamping, embossed embossed plate. From the exposed zinc plate image, it is required that the lines of the embossed hot stamping and the outer edge of the pattern have a thin solid line, which is a combination of hot stamping and embossed embossing It is very important to complete the process at one time. It is mainly used for cutting bronzing and non- bronzing parts. After the bumps, the part on the paper is concave, and the concave edge of the part is visually set off by the convex part.

Bronzing and embossing printing plate: Expose the pattern on the synthetic and shaped bronzing and embossing negative film to the plate, after washing, dyeing, and hardening. After high temperature baking at about 190°C, the layout is trimmed.

Corrosion of bronzing and embossing plate: ①Shallow corrosion, put the zinc plate after high temperature baking and trimming in a 6•Bc nitric acid solution, and use a brush for shallow corrosion treatment, and determine the embossing according to the thickness of the printing paper To determine the depth of shallow corrosion in order to achieve the pre-corrosion effect. Generally, the corrosion depth is about 0.1 mm and 0.2 mm. It can meet the hot stamping and embossing requirements of about 80-150 grams of paper. If the paper is more than 250 grams. , The depth of the embossing corrosion can be deeper. ② Partially fill and paint, after the shallow corrosion meets the requirements, take it out and rinse with water to dry, and then use anti-corrosion glue to fill in the lines and patterns that need to be bronzed and the anti-corrosion of the embossed parts Cover to protect the screen. ③Deep corrosion: Install the filled zinc plate in a powder-free corrosion machine. The construction work is carried out according to the normal corrosion time and requirements, and the corrosion depth of the edge is generally about 0.6-0.65 mm.
