Dye sublimation
Dye sublimation
The main advantage of dye sublimation is that the ink is forced into the fibers of the fabric instead of staying on top of the fabric. This results in brighter, more vibrant colors, more resistant to weather, washing and environmental conditions. This also means that the material maintains its look and feel, which is important in some décor applications, such as cushions or curtains, and some logo uses, such as flags.
In addition, Mutoh European Marketing Manager Nick Decock said that dye inks are cheaper per liter than solvent or UV inks, and added: "I think if you have the quantity, then you can make a better business case for dyes. Mr. Bray pointed out , Some printing buyers specify water-based inks, in order to meet their environmental goals or avoid risky odors, sometimes printing is related to ultraviolet rays.
Until recently, the standard method of dye sublimation was to first print the ink on transfer paper, and then use a calender or heat press to sublimate the ink from the paper to the textile. This method is applicable to various polyester materials without any type of coating. It is particularly useful for stretchable materials, which are sometimes used for curved light boxes. Mr. Decock pointed out that this method can also be used to transfer images to objects such as cups or mobile phone cases. However, you need to consider a heat press between £20,000 and £60,000.
In recent years, the method of replacing the direct printing of textiles has been greatly improved. Stephen Woodall, sales manager for textile printer blending services, said that for soft signs, transfer dye sublimation is too long and too expensive, but direct dye sublimation is beginning to become more and more popular, mainly because of the lower cost per square meter. He said that direct printing usually requires a coated medium, but it will be a lightweight liquid coating to prevent the ink from bleeding or dripping, which will not affect the handling of the material. Most, but not all, these printers also include an infrared fixed unit, so no further processing is required.
