Matters Needing Attention in the Design of Heat Transfer Products

Heat transfer printing is widely used in textiles, daily necessities, cosmetics, toys, gifts, electrical appliances, food packaging, building materials decoration, and other industries. What should be paid attention to when designing heat transfer printing products?

Multi-color overprint should be avoided in the design of heat transfer products. Because most the substrate materials have great thermal flexibility, and in addition, they encounter thermal deformation during high-speed printing, which makes printing overprint more difficult. Therefore, when designing patterns, multi-color overprints should be avoided as far as possible without affecting the design effect. In addition, the design should be simple, and generous, and avoid large-area color filling. Whether the patterns of finished units need to be connected with transparent or the same color is also a place that should be paid attention to in the design of heat transfer products.

Selection of design materials for heat transfer products

During product design, the packaging materials used must be consistent with the product market positioning. In the heat transfer printing process, the ink always occupies an important position, because after the heat transfer is completed, the remaining ink is attached to the product, which not only determines the quality of the product but also affects the printing speed. There are many heat transfer inks in the market, and their classification is very complex, but they have been labeled as highly polluting for a long time. In recent years, the voice of environmental protection in society has become higher and higher, and printing enterprises have paid more and more attention to the health of workers. New types of ink without pollution and less pollution have also been developed and applied. Today, with the rising tide of green environmental protection, many businesses choose an ink that can pass the environmental protection test.

Design resolution and color of heat transfer products

When selecting a color, the actual reproduction effect of printing shall be taken into account, for example, the color in the purple system shall not be used as much as possible. The reason is that the purple color obtained after the superposition of cyan ink and magenta ink in the printing ink is generally “dirty”, which is difficult to achieve the color shown to the customer in the computer display or the color effect expected by the customer in the design pattern and is easy to cause quality accidents related to the color. If it is really necessary to print the ideal purple color, it is recommended to use peach ink for superposition or spot color printing.

In the design of heat transfer printing, the resolution must be set according to the requirements of the printing process. Generally, the printing screen line reaches 150 lines, and the design resolution is 300dpi.

Design and layout scheme of heat transfer products

It is necessary to determine the transfer method according to the products and drawings before typesetting; Then determine the specification and size of the version according to the order quantity of the product;

To sum up, in order to realize the successful leap from “work” to “product”, designers must deeply study the relevant knowledge of the printing process, select and set the parameters on the process issues discussed above, and skillfully apply them to specific product design, so as to successfully realize the requirements of printing batch industrial production, continuously guide and reduce production costs, and create more value for customers.
