② proofing device. Shai Banji is a proofing device, Bike Flags For Sale the exposure apparatus of the photosensitive material. Mainly by the the parts of the box of glass the sun, underframe, vacuum pumps, lamps and lanterns, and and so on on composed of. Shai Banji of different points of the common of plant, large bezel below the rubber box at the top. The lights can be placed below or the side.
a simple drying rack. If there is no vacuum plate, can also be made easy proofing device. For example: the production of a triangular metal framework, coupled with the thick white glass (

Cold light source Shai Banji vacuum and air pressure set the device to ensure that the network version and the positive paste actual selection of the sensitive zone of the radiation source and the photosensitive material that matches the Designed for light exposure greatly increased speed (exposure time 1 to 2.5 minutes ). Reduce the radiation, the major improvement of operating conditions. Saving up to 85%, is the ideal proofing light source.
The vacuum plate, silk wind plate side installation of the glass box, Bike Flags For Sale the other side of the blanket box is installed, both with a special hinge connection at one end there are two frame fixed to the handle. Blanket around the set with a high degree of 10 ~
Proofing first coating emulsion Edition together with the positive bottom plate placed on the glass above cast a blanket, fastening the two boxes out of the air inside the vacuum, so close together (Figure 2 – 98). down to the glass surface perpendicular to the horizontal eliminated, exposure to a certain distance is the largest way. There facing the glass and chandelier-type light irradiated from the top of the glass face down on the irradiation of light from the bottom of the beam type; light along the mobile scanning various types of glass surface.
