The sublimation transfer printing process has the characteristics of low investment, no pollution, resource saving, outstanding printing effect, etc. It has a wide range of application fields and has developed rapidly in China. At present, the dye sublimation transfer printing process has been included in China's State Economic and Trade Commission's key industry cleaner production technology-oriented catalog (the first batch of No. 45), with very objective development prospects.
The development direction of the sublimation transfer in the future can be summarized as follows:
1. No version
At present, one of the main methods of sublimation transfer printing in gravure printing is that the products produced by this process have a natural transition in pattern and a strong three-dimensional effect. However, the plate making cycle is long and expensive, and it is not suitable for personalized production of small batches. With the digital development of printing technology, sublimation transfer is developing in the direction of digital plateless. Digital dye-sublimation inkjet printing technology uses dye-sublimation ink to print the pattern directly on the transfer paper through the printer. This technology does not need to make a printing plate. Personalized production of customized products.
2. Paperless
The most remarkable feature of paperless sublimation transfer printing is that the transfer substrate can be reused. The current sublimation transfer paper mainly uses a high-priced paper base as a base material, which is not only expensive, but also has inevitable wastewater discharge problems in the base paper copying and waste paper recycling processes. The paperless sublimation transfer printing undoubtedly solves the above problems and is a technical breakthrough for the future development of the sublimation transfer process.
3. Reuse
Thermal transfer paper with graphic information can only be transferred once. Once the graphic information is transferred to the substrate, it cannot be transferred again. Based on this, research on the technology that can perform multiple transfers to control thermal transfer The release of dye on paper makes quantitative dye transfer and achieves the purpose of multiple transfers, which has become the subject of many research institutions. The transfer printing can be efficiently used multiple times, which not only reduces the use of base paper, but also saves energy and protects the environment, and also reduces the cost of the thermal transfer process.
