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 (5mm), Bike Flags For Sale four weeks pad with rubber strips to protect the glass four sides of the triangular metal framework squeeze crack. The first soft camera at the bottom plate when the  down into the white glass, and then the complex has been coated with the photosensitive layer of the box, the box fill the foam block, add a tablet in the box, some heavy bottom plate pressure bright lights. Bike Flags For Sale Now made easy  down frame, some with a wooden box, inside the four weeks Post aluminum skin, fitted with fluorescent tubes. The top of the box put a thick glass,  down the bottom plate on the glass, coating and put on a good wire steel version, and then compacted in the above seal, to proofing.

The above-mentioned drying racks, proofing and only relatively simple graphics, fine graphics still need to vacuum printer.

(b) vacuum printer. Proofing and plates by fine lines or network, you must use with vacuum tightening device and light source consisting of a selection of special edition Shai Banji.

Shai Banji in two forms: one is horizontal Shai Banji, Bike Flags For Sale a vertical Shai Banji. Both plate, compact structure, glass sun boxes, vacuum pumps, light source in the same cabinets, easy to operate, suitable for small and medium-sized version of the proofing.

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 ~ 15mm, width of 20 ~ 30mm rubber band handle combination of a fixed two boxes, with the vertex close to the glass to block out incoming air, the air inside the vacuum pump after-out of version of membrane on the can be used with the negatives of the yang diagram completely dense co-. Proofing when positive bottom plate of silver emulsion membrane surface with the surface of the emulsion seal emulsion membrane surface of the positive bottom plate must be carefully defined.

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.
