Ketu Tai Autotype Five Star Red film (FIVE STAR), FIVE STAR is the world's most popular film of the indirect, the use of simple, graphic precision, the mesh has excellent adhesion. 
 Usage: 
 This film required to access the yellow safety lamp, and cut the required size, immediately back into the box. Do not bend the film and the separation of its membrane and film base, leading to exposure of the damaged part of the poor. 
 Exposure 
 Cut film cut the size required, the negative membrane surface and the five-star red and soft pieces based on the Shai Banji surface contacts within the vacuum ultra-violet light exposure. Occurred in a different light intensity is different. Especially the carbon arc lights, so to determine the correct exposure time is very important. Exposure of the slide rule to help determine the exposure time. 
 Hardening 
 After the exposure, immediately the exposure light film all over 1.2% hydrogen peroxide immersion hardening liquid for 1 minute. Hardening solution must maintain the temperature of 19-21 ℃, hardening powder deployment of activated powder (100 g per package with 2 liters of water.) Such as the concentration of hydrogen peroxide is not a commercial 1.2%, 1.2% should be deployed into the solution. 
 Wash 
 Warm water with a 40-45 ℃ evenly sprayed on the exposed film, when the membrane is no longer a part of image, transparent mesh, to continue to at least 30-60 seconds, rinse significant (especially in the production of precise exposure when the film). After the photographic film and then developing a good water spray cooling. Cold water temperature not lower than 10 ℃, or when the film posted on the Web version, its adhesion will be reduced. 
 Post Net 
 Network box screen must be rough treatment and degreasing treatment, that to obtain optimal results, the photosensitive adhesive film cooling wire immediately posted online in the humid (moist film will be placed on shading, touch screen surface and membrane .) Absorbent paper on the film under a stack of newsprint on the screen frame and then the ink surface, roll back and forth with a squeeze, suck out all excess moisture. Note Do not roll too hard to prevent damage to the film on the membrane of Patterns (if not fully dry the water, the water flow on the film may cause a blocking network.) 
 Drying 
 Natural drying or drying with fans, must not dry baking heat, otherwise the film will curl and damage the edge. Image film dry, the surface of the film base image film is easily peeled. 
 Close up 
 Image film and the web space between the border must be closed with censorship pulp, dry delivery printing.
