By studying the fundamentals of display screen mesh and fabric preparation, you may shortly improve the standard of your prints and prevent common display problems resembling pinholes, poor element, and poor ink protection. We will begin by explaining mesh counts, weaves, and thread diameter. Once we’ve got a primary understanding of the mesh itself, we can have a look at stretching and getting ready the display mesh for emulsion.
Polyester monofilament is your best option for textile display screen printing. Stainless steel, nylon, screen printing mesh and silk are additionally accessible but the polyester is the commonest for garment printing. Two different types of mesh weaves can be found. Plain weave is a simple one-over/one-under pattern much like a basket. This enables for a very sharp print if you end up display screen printing detailed designs. Twill weave is a two-over/two-under pattern. This doesn’t present the sharp element just like the plain weave nevertheless it does allow for screen printing mesh more ink to move through the mesh at greater mesh counts. Most applications are finest when printed with plain weave mesh.
Thread thickness is also very important. You might not notice it but many mesh counts that you just order are available in several thread sizes. For example, 305 mesh depend is out there in a thread thickness of 31, 34, and forty microns. The 305 mesh depend display with 31 micron thread diameter is ready to tension 21 to 24 N/cm. This is way much less tension than the forty micron thread (27 to 32 N/cm). You might want the tighter screens for high-end printing however you also must consider the change of ink deposit between the different screens. Even though they’re all 305 depend screens, they all have totally different theoretical ink deposits and different fabric thickness.
Mesh shade can be something to think about. Customers typically ask what the distinction is between white and dyed mesh. I all the time recommend white mesh for counts starting from 17 meshes/inch to 158 meshes/inch. Anything above 158 meshes/inch it will be important to make use of dyed mesh. White mesh has a tendency to refract light.

This causes undercutting of your stencil. You possibly can lose necessary detail. Yellow mesh reduces refraction because it reduces the travel of ultraviolet gentle. Dyed mesh will take a longer publicity time however it’s a small value to pay whenever you could possibly be losing wonderful strains and half-tones. Using proper mesh tensioning procedures will allow for optimum print control and performance. It is vital to understand that one definitive mesh tensioning level does not exist. Every mesh rely, each thread diameter, and each thread material may tension at totally different ranges.
The ultimate step is making ready your screen properly and persistently. This is just as important as selecting the best mesh rely for the job. Mesh pretreatment is the technique of cleaning and preparing the screen mesh floor to improve stencil adhesion and eradicate coating defects, coustic mesh with the final word purpose being optimum stencil efficiency and durability. It’s important to use an abrader/degreaser when you have got stretched new mesh materials or obtained new pre-stretched screens.
It will allow your liquid emulsion or capillary film to adhere to the display higher which prevents pinholes, fisheyes, uneven stencil thickness, air pockets, and stencil breakdown. Using household products akin to Comet or caustic degreasers isn’t advisable. The proper chemicals do not just clear the mesh floor, they put together the mesh for the stencil. If your display screen mesh just isn’t virgin, you only want to use a degreaser to deal with the surface. Older display mesh may require a haze remover when it becomes stained.
