Thermosetting ink characteristics and selection

Thermosetting ink, also known as plastic melt ink, plastic ink, resin ink, etc., mainly composed of plasticizers and resins, and additives and pigments. Because it has the property that it must be heated to cure, it does not plug the net during printing, and it can wet and wet continuous printing, greatly improving the production efficiency.

PLASTISOL is a new generation of textile printing ink. Due to its numerous advantages, it has largely replaced traditional printing materials in foreign countries. In addition to the use of glue and water slurry for processing under certain customer-specific requirements, most printing manufacturers already know and use PLASTISOL to process high-precision products.

In China, there are distributors of thermosetting inks several years ago, such as Guangzhou agent of LANCER company in Canada, WELFEX company in the United States, and KFG company in Italy all set up distributors in the mainland. At that time, domestic printing manufacturers had become accustomed to using glue and water slurry to process products, and the processing technology and equipment were backward. In addition, the agents only promoted ink during the promotion period, and they did not have matching equipment and color separation plate making technology. Therefore, it is impossible to meet the needs of customers for producing high-precision products from the configuration of production projects.

Recently, a company specializing in printing design and color separation printing in China, Shenzhen Colorful Square Printing Design Co., Ltd., has met the needs of customers for design and platemaking to a large extent. And because of the manual and automatic printing machine's improvement in precision, it also provides the conditions for the popularization of thermosetting ink in China. In order to make more users understand the use of urushiol inks and their characteristics, we will give a brief introduction here.

Table 1 is a comparison of three textile printing materials.

In use, the thermosetting ink must be infrared heating, the temperature in the 140 °C ~ 160 °C, the time is 40s (seconds) ~ 1.5min (minutes) to be fully cured, the dark white shirt on the surface to be dried, to increase Covering power.

The Italian company KFG recently introduced a high hiding power of plastisol ink with a more vivid color and less material. The high content of color paste allows the dots to stand up well and does not spread. With professional design, it can guarantee a fine photo effect and greatly reduce costs. At the same time, this kind of ink can be used for walk-in production, and it can be hot-baked in conjunction with the conveyor oven and the walk-in oven produced by the Shenzhen Hong Kong company, which can greatly improve the efficiency.

Thermosetting inks make the photo effects that were previously difficult to achieve on textile printing become a reality, and the clarity and reproducibility of the images cannot be achieved with other materials. Combining with the popular Titanic, World Cup and other graphic designs, you will find that not only the cost and efficiency have greatly improved, but also bring you greater benefits and market competitiveness, while your reputation is also excellent due to thermoset inks. The advantages and reliable product quality will be greatly improved. At the same time, relying on the continuous improvement of advanced technology and superior product quality of special effects, in the industry will get a good reputation.
