Learning outcomes
|
Students are acquaint with measurement of printing quality and some parameters of materials that are used for preparation of prints (measurement of conductivity and hardness of water and damping solutions, rheological properties of printing inks, lightfastness of printing inks etc.)
Student can measure parameters of printing quality with spectrophotometers (optical density, dot area, trapping, printing contrast etc.) and by CCD camera (optical density, dot area). Student can operate equipment for measurement of rheological properties of printing inks and knows parameters of studied materials that influence quality of prints. Student can prepare black and white photography.
