When making screen printing plates, the basic conditions for selecting light sources are as follows:
â‘ Light source intensity The light source used must have a certain intensity, and any type of original should be able to meet the needs of exposure in a short time.
â‘¡ Stability requirements The intensity of the light source used must be stable during the exposure process, and cannot be suddenly strong or weak.
â‘¢The illumination intensity of the light source used for the uniformity of the light source illumination on the original must be consistent. That is, the center and surrounding positions of the original must be under the same light intensity.
â‘£The light source used for high efficiency should be exposed in a short time, and the exposure effect can be achieved.
⑤Operation and maintenance are simple. The selected light source equipment should be easy to operate and easy to maintain.
