Detailed operation of making hot stamping zinc plate for business card

Types of bronzing plates: silicone bronzing plate (silicon bronzing plate), zinc plate, copper plate

Corrosion method (potion): The red copper plate is made of hot stamping by deep corrosion. There are special powder-free corrosion machines and corrosion solutions (ferric chloride liquid + hydrochloric acid + anti-side corrosion agent) in the market. The corrosion depth is generally 0 .5 ~ 0.6mm is better. Now some people use electrolytic etching machine to make bronzing plate, and the effect is also good.

Production process: black and white draft design ~ black and white draft or film copy (flip) ~ gluing ~ printing ~ edition ~ corrosion bronzing plate ~ embossing plate processing ~ full page

(Details) The synthesis of bronzing and embossing is to combine the yin and yang of the bronzing area pattern and the embossing part pattern into an organic integral film base. The plate is processed by a special process, printed and corroded to obtain a bronzing and embossed plate. .The finished product requires the convex part, while the zinc plate is concave. The finished product requires the concave part, while the zinc plate is convex. Now the production process is introduced as follows:

Stamping and embossing negative film synthesis: according to the design requirements, the photographer first pastes the drawn manuscript with the yin and yang cross gauge lines and then takes a negative image ① and then copies, develops and fixes the negative image normally to obtain a positive image ②, and then still When copying 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 thicker outlines is obtained ③, and then the positive image ③ is pasted with black ink. Fill in the outline, wait for the positive image ③ to dry, use it to copy it, and copy the negative image ④ with a transparent outline in the method of less exposure and more development. After overlapping and splicing the yin and yang cross lines, stick them with adhesive tape, and use them directly for printing, corrode to make bronzing and embossing. You can also get a positive picture with a clear outline after the spliced film is copied to the yin and yang. Then corrode the positive image ⑤ to obtain a bronzing and embossing plate. From the image of the zinc plate, it is required that the bronzing protruding line and the outer edge of the pattern have a thin solid line, which is a combination of bronzing and embossing. It is very important to complete the process at one time. It is mainly used for the cutting of bronzing and non-bronzing parts, and at the same time, if there is a convex edge around the pattern, the thin solid line will be convex after corrosion. After the embossing, the part on the paper is concave, and visually, the concave edge of the part sets off the protruding part.

Bronzing, embossing and printing: The pattern on the synthetically shaped bronzing and embossing negative film is exposed to the zinc plate, after washing, dyeing and hardening. Then after high temperature baking at about 190 ℃ and layout trimming.

Corrosion of hot stamping and embossed plate: ① shallow corrosion, put the zinc plate that has been baked and trimmed at high temperature in a 6•Bc nitric acid solution, and perform shallow corrosion treatment with a brush, and determine the embossing according to the thickness of the printing paper To determine the depth of shallow corrosion in order to achieve the effect of pre-corrosion. The general corrosion depth is about 0.1 mm and 0.2 mm. It can meet the requirements of bronzing and embossing of about 80-150 grams of paper. If the paper is above 250 grams, bronzing , The depth of the embossed corrosion can be deeper. ② Local filling and coating, after the shallow corrosion meets the requirements, take it out and rinse it with clean water and dry, and then use anti-corrosion glue to fill the lines and patterns that need bronzing and embossing for anti-corrosion. Cover to protect the picture. ③Deep corrosion: put 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 edge corrosion depth is generally about 0.6-0.65 mm.
