(2) Exposure: the film within the film and the bottom plate is pressed against the plate, with exposed carbon lamp or a xenon lamp. Distance between the screen frame and the
light source is 50-60 cm, exposure time 2-6 minutes.
(3) Development: After exposure, the Philippine film on the plate, with warm water for 1-2 minutes omental infiltration, water spray nozzle with an aqueous to the
non-photosensitive portion (graphic section) copy, after the development of the Philippine film, until the shape is clear.
(4) paste film membrane: the film was exposed to the membrane surface attached to wire-line, on the back of people's with a rubber membrane plates or other straight, gently
scrape paste, the film is firmly in contact with the net, immediately placed in an oven at a temperature of bake 8-12 minutes under the conditions of 55 ± 2 degrees, after drying, the screen
frame is fixed to the plate bench proofing.
(6) to film methods: exposure, development process, when found defective version, the film can be immediately washed off with warm water to re-create. If the version has dried
or after a period of time to film production, the available industrial sodium hypochlorite and water each one, soak for 10-20 minutes. Or 5% aqueous sodium hydroxide heated halftone processing,
film can be removed.
C, between straight plate method: straight between direct and indirect method is the method of mixing the plate method, which differs from that of the indirect method, the
indirect method in the first film after the film do go down to the wire image posted online, and straight France is among the first film after the film posted online exposure wire manufacturing
an image.
