How to choose mesh correctly in manual printing

By modifying the composition of the thermoset ink, it is possible to make the ink easier to use in manual printing production, but for manufacturers of manual printing thermoset ink, the best way is to adjust the mesh size to fit the ink. transmission. The viscous ink needs a larger mesh to flow smoothly, so the application of thick flowing ink between rough meshes is not suitable for printing with extremely precise lines and tiny details, such as 85-line screening. , unless there are screen printing workers or printers who are very proficient in professional knowledge and have considerable experience. Of course such work is achievable, but it's actually a different kind of creation. A simple rule is that to keep the proper amount of ink delivered to the substrate, the mesh openings must be uniform in size so that at least three drops of ink can be delivered to the substrate at the same time. The good news is that it is not necessary to measure the size of the ink particles by hand, because most ink manufacturers will do the measurement work in advance, and provide suitable mesh size parameters for the various ink products they produce in the detailed instructions. It is important to remember, however, that these recommendations are for automatic printers, and for manual printers, you have to switch to a coarser mesh.

Similarly, each mesh manufacturer will provide the corresponding theoretical ink volume (TIV) in the detailed specification for different combinations of mesh number and mesh diameter. This number will be the secret to the success of outstanding screen printers, and determines the key to perfect screen printing in just a simple mesh on the printing machine. An easy way to use the TIV value is to print a selected logo pattern with a specific type of thermoset ink on the screen that is expected to be most suitable, and then observe the change in the ink after curing in the dryer. If a 20% increase in ink is required to achieve the desired opacity, choose a TIV value that yields a 20% increase in ink. This operation is really so easy.

In addition, it is also necessary to pay attention to what preparations must be made to prepare the changed ink on a manual printing machine? In fact, as described above, the first step in the method of selecting the screen plate and TIV value reasonably is to realize the suitable ink. Precise delivery. Because this does not require any modification to the ink itself, there is no need for more labor costs in long-term operations, saving production time and cost consumption. So, this is the best way to adjust inks in garment printing.
