2) is preferably a vacuum state in order to ensure the sharpness of the halftone pattern and the sawtooth and biting teeth phenomenon, let halftone to ensure full contact of the backsheet and the photosensitive layer should be remembered that the exposure to dyeing mesh time longer.
3) in the use of the tunable light source (position adjustable), In order to ensure uniform and reduce the biting teeth phenomenon, the halftone exposure distance is preferably 1.5 times the diagonal of the pattern by the sun or the diagonal length of the halftone 1.5 degrees.

4) lack of exposure, often brought to the screen can not be reused or with trachoma and serrated. Flush, if the network version of the squeegee surface sticky and soft feel, indicating that the halftone underexposed, i.e. not enough light reaches the squeegee the surface of the photosensitive layer, so that the photosensitive layer can easily be washed away. Meanwhile, the underexposed, the photosensitive layer is softer or the photosensitive layer is washed away. The network version is not resistant to mechanical abrasion and solvent resistance.
5) Sometimes, the underexposed Screen also take remedial measures. : Gently rinse off the screen, will be washed away by the softer photosensitive layer, rub with White, and then drying the screen, and the last exposure.
Note, the squeegee side facing the light source.
