1, Preparation work before printing
1. Raw material preparation: The raw materials used for tinplate printing are tinplate sheets and printing ink. Tin plate is usually made of tin plated iron sheet, which has good anti-corrosion performance.
2. Equipment preparation: including printing machines, die-cutting machines, hot stamping machines, etc. Printing machines are used to print patterns on tinplate sheets, die-cutting machines cut tinplate sheets into specified sizes, and hot stamping machines are used to heat stamp gold foil on patterns to increase their splendor.
3. Material organization: Classify and organize the tinplate sheets to ensure that there are no impurities or curled edges. Meanwhile, verify the size of the pattern to ensure compliance with the requirements.
2, Technical points in the printing process
1. Printing positioning: Place the tinplate on the printing machine for precise positioning to ensure the accuracy of the pattern position.
2. Printing color: Choose the appropriate color for printing according to the needs, usually monochrome, two-color, and multi-color printing.
3. Hot stamping treatment: For patterns that require hot stamping, it is necessary to perform the hot stamping operation immediately after printing. The hot stamping temperature and time need to be precisely controlled to ensure the hot stamping effect.
4. Quality inspection: After printing and hot stamping are completed, quality inspection is required, including the integrity of the pattern, hot stamping effect, etc., to ensure that the product is qualified.
3, Processing methods after printing
1. Packaging and storage: Classify and package the printed tinplate products, and store them in a dry and dust-free environment to prevent rusting and deformation.
2. Delivery and Shipping: According to customer needs, the printed tinplate products will be delivered and shipped.
