Heat transfer printing is an energy-saving and emission-reducing printing technology, which is green and environment-friendly. It mainly solves the characteristics of long printing time and tedious process of traditional printing technology, especially provides an efficient and energy-saving printing scheme for fast printing, and realizes WYSIWYG. Thermal transfer printing mainly uses transfer film to print and process, computer typesetting good graphics, and thermal transfer printer can print the required patterns by heating the transfer film.
1. Characteristics of thermal transfer printing process
A product loss is small, added value is high, and process decoration is strong.
Thermal transfer technology can use a variety of different transfer materials to achieve different printing effects. The most important ones are adhesive film transfer and sublimation transfer.
B high hiding power and strong adhesion.
The transferred transfer paper of the adhesive film contains colloid, and then the colloid pattern is printed on the surface of the article by high temperature and high pressure. The printed colloidal pattern is very thin, breathable, non-sticky, non-cracking, wear-resistant and non-shedding.
C meets the green printing standard, saves energy and has no environmental pollution.
Fundamentally, it ensures bright colors, environmental protection, meets international standards such as Europe and America, high-quality equipment and advanced color management system, eliminates the unstable factors of color in digital printing, and minimizes the defective rate of products.
2. Heat transfer treatment and luminescence With the development of society and the progress of science and technology, personalized heat transfer printing, heat transfer processing and other technologies have gradually penetrated into people's lives. From clothing to daily necessities, household goods, art supplies, power industry of State Grid, and logo industry, it will change continuously with the progress of science and technology.
3. Problems needing attention in thermal transfer printing In the production process of thermal transfer film, it must be heated before printing. But the products produced by different technical masters are different. Thus, heat transfer film needs rich production experience and strict production requirements.
The following are some important considerations:
A. Temperature: Different product materials need different temperatures, because high thermal transfer temperature will damage the product itself, and low temperature will lead to poor printing quality.
B. heat transfer time. Time is very important, because heat transfer is carried out at high temperature. Time must be strictly controlled.
C. pressure, because the pressure in production is too small and the gap between fabric and printing paper is too large, it will lead to unclear transfer printing. When the pressure is too high, it will lead to deformation, rough hand feeling and other problems.
In short, it is required to strictly control the production process and master the technology in thermal transfer printing.
