The commercial or non-commercial screen printing machine users should know some special requirements to print high-quality images in screen printing artwork. The printing technology has reached the peak of the world printing. Let’s look at the things you must know.
In the screen printing process, the thing that is you need first is screen or mesh and it is the most vital element. Screens may be different types, colors, and resolutions. Whatever you print in your screen printing machine like caps, sweats, shirts, signs etc, you must print a high-quality image and good quality product. You must need to select a particular screen for particular products and it may be wooden, plastic, metal or aluminum. The Image might be close and one side must be the thin bar for t-shirt or cap printing.
In addition, you have to take out of the registration from the mesh while you are printing a minimum amount. Next, you have to drive the ink into the fabric properly. When seeing the color, you need to a second time printing. It is difficult to apply to the tight screen. The low tension screen is good to apply the ink. While printing is running, you have to clean the mesh periodically. The tension of one side will be lower and thinner than the other area of the screen. A lot of ink is gathered at the low tension button area of the image. For the high tension screens, you can follow some tips to create the high-quality image.
Screen Printing Tension
To print a cap on screen printing machine, tension is more important than t-shirt screen printing. It is because of the foam front caps which is quite different from t-shirt and other items. For any size of screen printing, the screens should be glued and stretched properly. Without removing the mesh, you can use an aluminum or retentional frame tightening the mesh.
You have to use a thin steel bar if the frame isn’t retentional and it would better than the wood or aluminum. When you start to attach the mesh, you can increase the tension towards the center. Sometime oil may have in the steel. How to remove the oil? You better can use material like alcohol or spirit to clean or fresh the steel. To use the ink properly on the surface of your artwork, the squeegee and the screen need to have sharpness like the blade of scissors.
The Squeegee for the cap is a little bit different from the t-shirt squeegee. The Squeegee blades should be 4 inches long for a cap screen printing press. Blade selection for cap screen printing is a key fact. 75-95-75 durometer blade is quite good for t-shirt screen printing. Whether the blade is made of aluminum or wood, you should have the changing option for the blade. If the blade of the cap
If the blade of the cap screen printing machine is is straight, the squeegee should be also straight. To cut the edge of the cap, the blades need to be sharp. If it is not sharp, the edge would not be round. After finishing printing, you need to clear the ink instantly. The blade will be hard if the ink remains in the blade. After washing the blade with the chemical or with the water, you need to store the squeegee without resetting the blade.
Screen LEVEL for Screen Printing Machine
The level of the textile screen printing press is consisting of two parts-the platens and the screen. If any movement happens between this two, the press creates the disqualified image. Screen printers should check the platen by stationary materials. They should make sure all the plates same and they need to tape the plates with paper. It would better to add a flash dryer with the press and it should be at a uniform off-contact distance. After that, you should also check the level of the screen of your press with a piece of glass (larger than the platen). To put the screen on the press, the glass should be set up against the screen and it should be flat. When the color arm comes or rest on the off-contact, the mesh needs to flush and it must be against the glass.

The platen needs to push down and the platen needs to be very strong as like as concrete. If it is not strong enough, color registration problem may occur. You should make the channel clamp a little bit moves which hold the screen laterally.
Sometimes printing press requires bearing for multicolor screen printing equipment. A printer must load the bearing to run the multicolor press properly. Bearings should be given pressure if the screen doesn’t rotate freely. A destructive thing can happen if spray adhesive and lint is used. Lubricants like WD-40 can be used for cleaning the bearing.
SPRINGS AND SEALS
For visual looking, springs are important. The coil all touched added with the spring. Remember, coil touching is vital. The spring will be too much large if it doesn’t touch the coil. Then you have no other way to replacement the spring. Heat tolerance is the another key fact for the spring manufacturer. The spring can be brittle if they are not proper heat treating and this can bring danger. To exposure, some
The spring can be brittle if they are not proper heat treating and this can bring danger. To exposure, some screen printing press users like to use air cylinders. The seals are used in that place where the rod enters. The air cylinders will not support the weight of the color arm or the screen and extra time seal wears. If somehow the seal gets worn, instantly you have to replace the air cylinder of your screen printing machine.
For the cap screen printing, platen size is a big problem. For the different type of t-shirt printing, you don’t need to use a full size and an adult platen. From many years, different types and sizes design have made from the foam fronts against the head. The platen would be perfect if you use flexible fonts on your screen printing press. After that, you have to take a pad like a mouse pad which will raise the screen high and will be the similar distance like off contact.
