Abstract: According to the present invention, there is provided a printed graphics inspection system and the inspection method thereof to inspect printed graphics including holograms. In the present invention improving the printing quality and reducing manpower cost are achieved by using of a plurality of sensors located in different angles to exclude zones not normally detectable on the graphics to be inspected, digitalizing the images inspected by such sensors, sending the digitalized images to a micro-processor, and using such micro-processor to analyze and process the images inspected and a set of corresponding templates to identify defects such as contamination, color deviation and the like.

Abstract: The present invention concerns a new, unconventional, mold-binding, water solidified polyurethane cast to be used in orthopedic departments for the correction of deformities, fixation of fractured limbs and joints, and mollification of affected parts, as well as the method of its preparation. The chief constituent, a polyurethane prepolymer, contains a stabilizer that can prolong appreciably the storage period of the cast material, maleic anhydride, and a mixed catalyst for control of hardening time, bis(2-morpholinoethoxy)ethane and anhydrous potassium carbonate.
