Learning outcomes
|
These laboratory tasks build mainly upon the Recording and reproduction technologies, Technology of offset and digital printing, Technology of flexography and gravure printing, Technology of print finishing. The objective of the course is to deepen the knowledge by their practical use (knowledge, methods and instruments).
Student can measure parameters of printing quality with spectrophotometers (optical density, tonal value, trapping, printing contrast etc.) and by optical miscroscopy (tonal value). Student can prepare colour and also black and white photography. Student can evaluate quality of adhesive binding and lamination. Students will deepen their colorimetric knowledge of colour measurement and its evaluation in chromaticity diagram CIExyY and CIELAB colour space.
