Water transfer standard ink is generally water transfer standard special ink, a batch of products had better use the same brand of ink, additives, diluents, glue, in order to avoid the chemical reaction. Water transfer printing ink, generally all over the supplier can buy.
When printing, first use the 200 mesh screen to print the white background. If the customer has no special requirements, it is forbidden to add white. Because the paper may have slight expansion and contraction, after adding white, the white background becomes larger, and the color behind it is difficult to cover the white background, resulting in incorrect color registration. For example, for products with white color, the white background should be as less as 0.5-1 mm as possible when making films from the original. After adding white, it is just the same as the background without white, so that the overprint can be accurate.
When printing the first color (white), first print a few angled lines (crosshairs) to facilitate the overprint of the second color, and then seal off all the redundant patterns such as the crosshairs at the needle position, leaving only the patterns needed by the product. What is the reason? Because the printed water transfer mark must be placed in water when it is attached to the object. The upper mask is separated from the bottom paper. After separation, the small cross line position is dropped into the water at the same time. The cross line will float along the water on the required product, which will affect the operation. After sealing off, there is no worry and convenience. After each color is printed, in order to prevent dust inhalation, we can use large newspapers to surround the environment and the top and sprinkle a little water on the ground at intervals, so as to prevent people from walking and drive dust fall on the printed products. In each color printing drying process, the only drying method is natural drying, must not use the fan, drying channel, dehumidifier to help to dry. Under the action of external force, the printed paper will become irregular expansion, waiting for you is the price of money.
