Application of water transfer printing ink and its printability

Water transfer printing inks are generally inks for water transfer labels. It is best to use the same brand of inks, additives, thinners, and glue in a batch to avoid chemical reactions. Water transfer printing inks are available everywhere at the supplier.

When printing, use 200-mesh screen to print white. If customers do not have special requirements, taboos will be added. Since the paper may have slight expansion and contraction, after adding white, the white color will become larger, and the back color will be difficult to cover the white background. , color registration is not allowed. For products with whitened colors, when using a manuscript to create a film, the white background should be as small as 0.5 to 1mm as much as usual. After adding white, just as with the background color without white, the overprint can be made accurately.

When printing the first color (white), first print a few angulations (crosshairs) to facilitate the second color overprint, and later need to completely seal off extra patterns such as the needle crosshair, leaving only the product Needed pattern. Why? Because the printed water transfer mark must be placed in the water when it is pasted on the object. The top film is separated from the bottom paper. After separation, the small crosshairs will fall into the water at the same time. The crosshair will follow. Water floats on the desired product and affects operations. After sealing off, there is no concern and it is convenient. After printing one color, in order to prevent dust from inhaling, we can use a large newspaper to enclose the circumference and the top, and sprinkle some clean water on the ground for a period of time to prevent personnel from moving around and drive the dust to fall on the printed product. In the drying process of each color, the only drying method is natural drying, which must not be assisted by fans, drying tunnels, dehumidifiers, etc. The printed paper will become irregularly stretched under the influence of external forces, waiting for you is the price of money.
