Raise four points screen printing ink color accuracy to note: 1. Printing: screen printing inks in most cases, the British import of small presses, the mesh of this machine is on a flat version, by circular platen roller belt Indian film to move forward to complete the printing, printing machine is Rotary way, the mesh is in rotation on the circumference of the roller. There are large differences wire mesh these two numbers, angles, etc., which makes the same ink printed in two ways, there is not a small difference, sometimes the problem is not just the color of dark light, and hue, lightness, and this will bring very different results. Some small factories with a squeegee-like ink sticks to, even worse. With plate factory to the color proofer, the effect will be much better than the imported small presses, and the prices are about the same, which can be made into printing proofer same version, can be designed according to the needs of different levels, the depth of print pattern, which makes printing and printing the same basic, but an important factor affecting the hue - plates, but also with the same printing plant. Version 2. Depth: different printed pieces have different version of deep, screen printing ink on the printed piece version used deep understanding or estimates also affect the accuracy of toning. Obviously, if the screen printing ink to time by 45μm deep color when printing, but the client's version is much smaller than 45μm, printed on lighter colors, and vice versa, it will darken. Some people think that is the standard provided by the user to control the ink transfer printing ink and need not be considered deep, in fact, this is the view of a theory, in practice is not the case. From the theory that exactly two inks (such as a glass of ink is divided into two), either version of the deep and shallow (other things being equal) which are the same hue. But in the actual color, it is impossible to deploy draw exactly the same ink, so often there is such a phenomenon; sometimes printed version of the color of light is closer (up to customer requirements), but if the print version of deep color on much worse, so deep grasp of version is very important, customer version deep, how deep it must use to print on the color version. How to make mirror silver ink to get the best printing results? 1, we must first understand dilute water mirror ink, printing technology is the key, when the printing speed is slow, on the one hand, dilute the mirror ink will leak water shed stencil, on the other hand, the mirror ink easy to absorb moisture from the air, after printing The resulting mirror effect is not good, for at the time of printing, ink mirror and pour network version must be continuous fast printing, printing to complete successfully, that is, the printing side edge workpiece inspection at this rate, will give impact printing effects, For example plugging ink printing ink does not go anodized wholesalers, slagging and other groups on the screen. 2, printing ink mirror when temperature and humidity are very important, because the ink on the screen easy to do, so we can not screen in an air circulation, otherwise very easy plugging, when the air humidity, the mirror effect is poor, and therefore In screen printing, as far as possible to avoid the flow of air and moisture. 3, since the ink dilute water, you should choose a high mesh screen, not only that, more rigid squeegee hardness should be more than 80o. 4, mirror ink stir before use to make aluminum and resin to be sufficiently mixed to ensure specular effect, otherwise, it will affect the produce mirror effect. 5, screen tension slightly lower net from also transfer nearer, and appropriate pressure reducing scraping blade, otherwise the mirror effect will undermine the formation. 6, printing machinery, used the knife back to Mexico is not hard aluminum or stainless steel, but should use gum knife back to Mexico, to ensure that the printing of mirror ink coating uniformity, the mirror effect is the same. 7. Mirror mirror effect ink glass ink with the dry way the wholesaler, the mirror effect in terms of heating dried natural drying less good, and attention should be consistent with warming temperatures and drying time, otherwise the mirror performance and color saturation will be different.
