Issues that should be noted in the design of thermal transfer products

1 Application of thermal transfer
Thermal transfer is widely used in daily necessities, cosmetics, toys, stationery, gifts, electrical appliances, food packaging, secondary injection molding, building materials and decoration industries. So what issues should be noted when designing thermal transfer products?

2 Thermal transfer product design printing artwork
Thermal transfer products should avoid multi-color overprinting in design. Because most of the printing materials used in gravure printing have large thermal elasticity, and they are deformed by heat during high-speed printing, making printing overprinting more difficult, so when designing patterns, try to avoid multi-color overprinting without affecting the design effect. In addition, the pattern should be simple and generous, and large-area color filling should be avoided. Whether the unit finished product patterns need to be connected with transparent or the same color is also a point that should be paid attention to in the design of thermal transfer products.

3. Selection of materials for thermal transfer product design
When designing a product, the packaging materials used must be consistent with the product market positioning. In the thermal transfer printing process, ink always occupies an important position, because after the thermal transfer is completed, only the ink is attached to the product. It not only determines the quality of the product, but also affects the printing speed. There are many thermal transfer inks on the market, and the classification is very complicated, but it has long been labeled as highly polluting. In recent years, the call for environmental protection in society has become louder and louder, and printing companies have attached more and more importance to the health of workers. New types of pollution-free and less-polluting inks have also been developed and applied more and more. Today, as the green environmental protection wave is rising, Guangdong Hongda Printing Industry has always used inks that can pass environmental protection tests, which has been unanimously praised by customers.

4. Resolution and color of thermal transfer product design
When choosing colors, it is necessary to consider the actual reproduction effect of printing, such as trying not to use colors in the purple series. The reason is that the purple color obtained by superimposing the cyan ink and magenta ink in the printing ink is generally "dirty", which is difficult to achieve the color displayed to customers on the computer monitor when designing the pattern or the color effect expected by customers, which is easy to cause quality accidents related to colors. If you really need to print the ideal purple color, it is recommended to use pink ink for overlay or spot color printing.

In the design of thermal transfer artwork, the resolution setting must be based on the requirements of the printing process. Generally, the printing screen line reaches 150 lines and the design resolution is 300dpi.

5 Thermal transfer product design layout plan
It is necessary to determine the transfer method according to the product and artwork before layout; and then determine the specifications and dimensions of the plate according to the order quantity of the product;
In summary, in order to achieve a successful leap from "work" to "product", prepress designers must deeply learn the relevant knowledge of printing technology, make good parameter selection and setting on the process issues discussed above, and skillfully apply them to specific product design, so as to successfully achieve the requirements of mass industrialized production of printing, and continuously guide and reduce production costs to create more value for customers.
