Water transfer mark ink is generally water transfer mark special ink, a batch of products best use the same brand of ink, additives, diluent, glue, to avoid a chemical reaction. Water transfer printing ink, like all suppliers, can buy.
When printing, first use 200 mesh screen printing white bottom, if the customer does not have special requirements, it is forbidden to add white. Because the paper may have a slight expansion, after adding white, the white bottom becomes larger, the color behind it is difficult to cover the white bottom, and the color is not allowed to be applied. If the product with white color is used to make a film with the original, the white bottom should be as low as 0.5-1mm less than the normal one. After adding white, it is just the same as the background color without white, so that the overprint can be accurate.
When printing the first color (white), first print out several angled lines (crosshairs), which is convenient for the second color overprint. All the remaining patterns such as needle position cross line shall be sealed off for the later ones, only the patterns required for the product shall be left. 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, there is no concern, convenience. After each color is printed, in order to prevent dust inhalation, we can use a large newspaper to surround the surrounding and above. Sprinkle a little water on the ground for a period of time to prevent people from moving around and drive dust to fly on the printed products. In the drying process of each color, the only drying method is natural drying, and it must not be helped by fans, drying channels, dehumidifiers, etc. Under the action of external force, the printed paper will become irregular expansion, waiting for you is the price of money.
