Offset sublimation inkis a special ink used for offset printing, which is composed of sublimating dyes, resins, solvents and additives, etc. When printing, the ink is transferred to the surface of the substrate, and after heating, the sublimation dye can be directly changed from solid to gaseous, penetrating into specific materials such as polyester, and the dye is re-solidified after cooling, forming a pattern text with bright colors, firmness and good water resistance, friction resistance and light resistance, which is widely used in clothing and home textiles printing.
First, the working principle of offset sublimation ink
The working principle of offset sublimation inks is based on the phenomenon of sublimation. During printing, the offset press transfers the ink containing the sublimating dye to the surface of the substrate to form a graphic imprint. Subsequently, under the action of high temperature (usually 180°C-220°C) and a certain pressure, the sublimation dyes in the ink are directly sublimated from the solid state to the gaseous state, and these gaseous dye molecules have high activity and can quickly penetrate into the porous or affinity materials such as polyester fibers. When the temperature is reduced, the gaseous dye molecules re-condense into a solid state inside the substrate, and are closely combined with the substrate fibers and other substances, so that the graphics and texts are firmly "inlayed" on the substrate to achieve a printing effect with rich colors, high saturation and good durability.
Second, a wide range of application scenarios of offset sublimation ink
Offset sublimation inks are widely used in many industries and are suitable for a variety of scenarios, as follows:
(1) Garment industry
1. Sportswear
It can print personalized team logos, numbers and patterns, with bright colors and washable and friction resistant, and can withstand various tests in sports.
2. Fashion clothing
Meeting the needs of designers for unique patterns and colors, add fashion elements to clothing, and enhance the added value of products.
(2) Home textile industry
1. Bedding
It can print exquisite flowers, landscapes and other patterns on bed sheets, quilt covers and other products to create a comfortable and beautiful sleeping environment, and it is not easy to fade.
2. Curtains
Various styles of patterns can be printed to match different home decoration styles, with good lightfastness, not easy to change color due to sunlight.
(3) Advertising and publicity industry
1. Posters
It can present high-definition, full-color images and texts to attract people's attention and effectively convey advertising information.
2. Brochure
make the graphics and text of the brochure more vivid, improve the overall quality and visual effect, and enhance the publicity effect.
(4) Decorative materials industry
1. Decorative painting
Realistic works of art can be printed on the substrate of decorative paintings of various materials to meet people's personalized needs for home decoration.
2. Furniture surface
Wood grain, stone grain and other textures are printed on the surface of furniture to simulate the effect of natural materials, reduce costs and enrich product categories.
(5) Digital product industry
1. Mobile phone case
Customize a variety of personalized patterns for mobile phone cases to meet the personalized aesthetic needs of consumers, and the ink has strong adhesion and is not easy to fall off.
2. Tablet computer shell
It can be printed with brand logo, characteristic patterns, etc., to enhance the appearance and texture of the product and brand recognition.
Third, Offset sublimation ink development prospects and competitive advantages
1. Market demand-driven growth
At present, consumers' strong pursuit of personalized products has prompted the demand for customization in clothing, home textiles, digital products and other industries to rise rapidly. With the ability to meet the needs of small batches and multi-variety personalized printing, the market space will be further expanded. At the same time, its application field is gradually extending from the traditional clothing and home textile fields to emerging fields such as decorative materials and automotive interiors, opening up new market growth points for it.
2. Technological innovation leads change
In the context of increasing environmental awareness and regulatory requirements, offset sublimation inks will develop in a more environmentally friendly direction in the future, and develop products with low volatility, low toxicity and low VOCs emissions. At the same time, through the improvement of the formula and production process, its color reproduction, gloss, stability and other properties will be continuously improved, to achieve higher precision, more delicate printing effect, so as to meet the strict needs of the high-end printing market.
3. Industry synergy to promote development
The cooperation between offset printing sublimation ink enterprises and upstream and downstream enterprises such as raw material suppliers, printing equipment manufacturers, and printing enterprises will continue to deepen, and jointly devote themselves to the research and development of new products and new processes, so as to promote the coordinated development of the entire industrial chain. In addition, cooperation with cross-industry enterprises such as textiles, clothing, and home furnishings will also become a trend, and further expand the application field by developing more targeted products and solutions through in-depth understanding of end-user needs.
