Before (1) silk screen printing ink, with cyclohexanone or other open water dilute and fully mixing, stirring evenly, let stand 20 minutes above used again, let the bubbles automatic overflow, otherwise, the bubble will be made by screen printing scraper scraping back and forth to print to the printing design, later bubbles burst, and prompted a pinhole printing design (blister), once appear this kind of situation, later it will be hard to make up for the defect.
(2) when the weather is dry printing, printing ink inside add slow dry agent in order to prevent plugging.In case of screen blocking happens, usable cotton dips in positive and negative swab cyclohexanone screen, to wipe through mesh before printing.Rainy day, inside the ink amount added to speed up the drying agent (or dry), otherwise the printing speed is too slow, lead to the low yield.
(3) more matching color printing, the printing order: the light - medium - dark.In a pattern, at the same time, there are scattered flowers and on-site printing, printing order: scattering flowers to the ground.When the first color surface drying, and then print of a color, and so on, until all the color printing.
(4) with fine lines or small dot pattern in design, should not be commonly added to speed up the printing ink dry agent, in this case, right amount add slow drying agent as well, as to add the exact proportion, should be depending on air dry wet at that time.
(5) after all the color printing, although visual or touch the surface of the ink was dry, but that's just the surface drying, printing design has not fully dry, therefore, when the winding, printing product can not be stacked high layer, so as to avoid printing surface is taken off layer after stress, only temporary stacking before shipment delivery, guarantee the quality of the products to the largest extent.
(6) different manufacturers, different varieties of ink is mixed with each other, especially the different varieties of ink must not mix use, for example: PVC ink can not be used with nylon inks, other varieties of ink.Why: mix after printing, it is difficult to found the problem at that time, in a few hours later, printing surface will gradually change color, design change, turbidity, cracking and even design.Of course, there are printing plant to reduce printing costs and risks in nylon PVC ink printing ink to add.Why bother?Province is also not a few money, one thousand out of the question, is too late to regret.
