Course which have preconditioned courses Chemigraphy
To enable students in engineering thinking and in acquiring knowledge in the filed of chemigraphy as a fundamental course, which is a theoretical introduction into making printing forms. Acquired knowledge is used in further education, and in better understanding of physical and chemical phenomena during the making of printing forms. Introduction to chemigraphy. Electricro-chemical processing of printing plates manufacturing - basic electrochemical processes in the preparation of printing plates, electrolysis, mechanism and structure of electrolytic coating, cooper plating, chrome plating, anodising aluminum. Surface phenomena - surface tension, wetting, adsorption. Copy layer processing - copy layers based on bichromate, copy layer based on diazo compounds, photopolymer copy layers. Metal etching - chemism, multiphase, single - and electrolytic etching. The mechanical properties of metals and alloys to produce offset plates - surface properties, metals for making monometallic and polymetallic offset platesa nd cliches. Basic concept of offset printing forms development - the chemical properties of printing plates, size of surface area, species adsorbed surfactants, the concentration of adsorbed substances, phenomenon of chemisorption. Active participation of teachers and students in classes with modern didactic devices, experimental laboratory work in small groups with the use of experimental techniques in selected areas of chemigraphy as the basis of the printing profession. In addition to lectures and experimental exercises are regularly held consultations.
