Last Updated ：2023/07/05
The aluminum sublimation sign blanks is a special panel produced by surface treatment of aluminum sheet, and then the designed color patterns and characters are printed on the conversion paper by inkjet printing, and reversed to the aluminum plate by heating, made of aluminum signs.
Production process of aluminum sublimation sign blanks:
Processing of base paper-printing protective layer-printing pattern layer-printing light-emitting layer-printing cover layer-printing adhesive layer-drying-packaging.
1. Protective layer. Use 300 mesh screen printing to print the transparent thermal transfer ink (if the ink viscosity is too large, you can use thinner to dilute to a suitable viscosity), the entire pattern is printed with transparent ink, mainly to protect the pattern layer, so that the pattern is resistant Grinding, washing, chemical resistance, and play a role in positioning the pattern. Use natural drying or low temperature drying.
2. Pattern layer. The pattern layer can be printed once with thermal transfer color ink. The screen mesh used is 300 mesh, and the viscosity can be adjusted with thinner according to the actual situation. The order of printing is mainly based on the color from dark to light. Pay attention to the accurate positioning, so as to avoid deviation when printing the light pattern again. Use natural drying or low temperature drying.
3. Light emitting layer. The luminescent material and the transparent thermal transfer ink are formulated into a luminous ink at a ratio of 1: 1, and the viscosity is adjusted with a thinner. Adopt 100-200 mesh screen printing, the number of printing is determined according to the luminous brightness. The luminous brightness is high, the number of printing is large, the luminous brightness is low, and the number of printing is small. Generally, two printings can meet the requirements. Use natural drying or low temperature drying.
4. Covering layer. Due to the use of luminescent materials to print the pattern, a white reflective layer must be printed after the pattern to increase the personalized effect. We use white thermal transfer ink to print the cover layer on the entire pattern with screen printing coated with a protective layer. Use natural drying or low temperature drying.
5. Adhesive layer. Finally, screen the hot-melt adhesive layer with 100-200 mesh screen to ensure that the entire pattern is covered. Mainly used to bond patterns and fabrics. Use natural drying or low temperature drying.
6. Finally, the packaging of aluminum signs. Pack the dried thermal transfer logo with packaging film and place it flat.
