For most clothing screen printers, choosing white ink has become their habit. We generally have a preconceived idea about the ink we like. Large garment printing factories can use any kind of hot-melt ink on their automated Stenter. As long as the craftsmanship in small printing factories produces printers and the craftsmanship proofing printers in large printing factories only need to choose clothing hot melt ink. In this type of printer, the function of the ink is the simplest evaluation. Although you can use any ink today, the human factor in the screen printing process can expand the characteristics of the ink.
White ink
The white hot melt ink plays the most important role in the daily work of the manual printer operator. Among the printed clothing drawings, more than half of the drawings require white ink. The biggest challenge facing printers is to select the best ink based on printing needs. Almost every manufacturer of hot melt inks has hundreds of white ink formulations, and they are selling a dozen or more inks at all times. Even though some white hot melt inks are particularly useful, their composition is still very vague.
You need to have a general understanding of the existing products. Nowadays, there are four kinds of white inks used in craft printers that can meet different needs. They contain a basic cotton white, a white for 50/50 cotton/polyethylene T-shirts, a nylon white and a polyester white for 100% polyethylene fibers.
Cotton White:
The white hot melt ink used for cotton materials is the easiest to use. Cotton fiber has fewer restrictions on the ink function than other materials. The most attractive features of this material are: simple printability, outstanding opacity and outstanding reflectivity. There are many versions of this hot-melt ink in the market. The best method is to test as many as possible to find the one that is most suitable for you. The functions of all these products should be compared and similar.
Flat Screen Printer Anti-absorption White:
Anti-absorption white hot melt ink brings great challenges to both manufacturers and end users. This is the most widely used white ink in the market, and the competition in the market is also intense. Manufacturers of hot melt inks release a new anti-absorption white ink every 12 to 18 months. These manufacturers have been trying their best to improve the formula of white goods, hoping to win more proportions in the clothing silk screen market. The challenge of using anti-absorption hot-melt inks comes from everyone's functional requests for these products. These requests include: outstanding printability, quick drying, high gloss, good opacity, soft hand, strong durability, outstanding smoothness and post-gloss characteristics. Each feature requires the manufacturer to make a different formula, so you will find a variety of anti-absorption white inks on the market. You need to test different types of inks from different manufacturers to find the one that suits you best. Most of the anti-absorption white inks have their own specialties; we can't integrate all the functions mentioned above into one product.
