Now, there are some techniques that can be used when painting a screen, one is to use both hands, which means you need to fix the screen in an upright position, or you can hold it with one hand and apply it with the other hand; Be sure to apply it with your hand. When coating, make sure the coating is even, as thick or thin areas can cause problems when the screen is exposed. If there is not enough lotion (thin position), your image will be exposed faster (overexposure), causing it to not be washed away. Thicker areas (too much lotion) do not quickly expose (underexposed), causing the image to decompose and wash away. Once the screen is finished, place it on the drying rack with the print side facing down to allow it to fully cure. Here are some tips for this stage; if you don't have a drying cabinet and only have a drying rack, apply a screen before going home to dry them overnight.

The 2&2 method is suitable for sports printing because it is applied twice on the printing surface and then twice on the side of the squeegee to produce a thicker stencil in the case of wetting. Rotate 180 degrees after each coating. This method requires longer drying times and exposure times. Finally, the 3&3 method produces the sharpest edges and the thickest template; starting with the 2 and 2 methods mentioned above, then applying a layer on the print side and drying.
