Choose a suitable white ink for screen printing machine

For most of the garment screen printing machine used, the choice of a white ink has become their habit. We usually like the ink on a prior idea. Large-scale garment factories printing presses in their use of automation arbitrary nature of a hot-melt ink. Only a small hand in the production of printing presses and large printing presses in the hand-proofing clothing only need to select hot-melt ink. In such printers, the ink most likely to evaluate the performance. Although you can now use any of the ink, but in the process of screen printing man-made factors are able to enlarge the characteristics of ink

White hot melt ink in the hand-press operator in a day's work played a most important role. Costume design in the printing, there is more than half of the design is the need for white ink. Printers are probably the biggest challenge is the need to choose the best according to the printing ink. Almost every manufacturer of hot melt ink has hundreds of white ink formula, and every moment they are in the sales of a dozen or more of the ink. Even some white hot-melt ink is a special purpose, and their composition is still very vague.

Curved screen printing techniques

Curved screen printing machine, although many ways, but in practical applications, often encountered in a simple curved surface printing, printed pieces of painted wood, but often give up because of conditions in order to close the economic opportunities lost. How can we solve this problem? After years of practical application, the use of live surface screen printing method, the printing of a large number of processing printed products, such as latex plastic barrels, clean buckets, basins, pots, cups, bowls, plates and other products. At the same time, the use of this method can be printed signs in the car on the word can also be profiled on the printing plane. Live the so-called surface screen printing, screen layout soon removed to directly close to the surface of the printing substrates.


Good first photographic facsimile editions of the text dealing with the dry patch, and then won by a good size cut. And in the screen at both ends with aluminum, such as wood chips or as a skeleton with tightly bonded with glue. Cement glue can also be used directly.
