Why do we need to spray a pre-treatment liquid before the white background is printed on the T-shirt printing machine, and there is no need for light colors? First of all, there is no need for light colors because the colorful inks for proofing in light colors are all water-based. Part of the ink will penetrate into the clothes, so pre-processing is generally not required. The dark color is not the same. The white background is not as low in concentration as the colorful ink, and there are many titanium dioxide components in it. This substance has the same composition as the correction fluid sold in stationery stores, and serves as a concealment. But it is easy to plug, so there is usually a steel ball in the correction fluid. Shake it before use. The same is true. The pre-treatment liquid is equivalent to a sticker or the same curing agent, so that the white ink of the pure cotton digital direct-injection T-shirt printing machine and the surface of the dark clothes are tightly combined. So this process is also indispensable, even for hundreds of thousands of original pure cotton digital direct-injection T-shirt printing machines, this pre-treatment liquid is also a must. Therefore, in the printing process of dark clothes using a pure cotton digital direct-injection T-shirt printing machine, spray the pre-treatment liquid first, then make the white background, colorful again, and finally dry it.
