Sažetak
Electrophotography is one of the most complex printing techniques. Elektrophotographic machines apply 5 basic phases in their work and they are synchronized repeated. They are corona charging, photoconductor exposition, photoconductor developing, ink transfer and photoconductor cleaning. The basis of the whole process is the organic semiconductor (photoreceptor), on which the virtual printing form for each impression is formed by exposition. Organic semiconductor looses its electric conductivity by numerous expositions which result in weaker adherence of toner to photoconductor. Except the mechanical wearing this is the main cause of quality loss of the final impression. This work gives the answer on how extremely great number of IR laser expositions influence the photoreceptor, and how such oscillations appear on a print. The photoconductor analysis lasted for 7 weeks, in which 131806 imaging (prints) were made. For determining the reproduction quality the densitometric measuring method has been applied (based on reflection from the printed substrate) as well as the spectrophotometric measuring methods (based on defining the impression inking).
