Course detail

Color Science and Technology

FCH-BC_CHBAcad. year: 2023/2024

The course is meant to deliver the attendees theoretical knowledge in the subject of color science and technology. These two complex and complementary subject fields include the theory of light and radiation, human response to light, interaction of radiation and matter, influence of chemical compostion of matter on its color and apperance, applied chemistry of colorants, basic principles of color reproduction, mathematical description and modelling of color etc. The course should explain the connection between the physico-chemical principles of material color and its technological application. A great deal of attention is paid to the desription and modelling of human visual system and objective color measuring.

Aims

The goal of this course is to give the students a detailed insight in the subject field of color science and technology. Thattendees should acquire the knowledge of terminology, understand the basic theoretical principles and abstract concepts, learn about typical related applications and major technologies. In this way they should acquire knowledge and skills necessary for their further study as well as professional carreer.
The improvement of theoretical knowledge, understanding and competences will be manifested in the following ways:
1) Course attendees will acquire complex knowledge of human visual system anatomical structures and biochemical principles. Further, they will also undestand the psychologic and psychophysical aspects of visual reception.
2) Course attendees will learn about historical and present approaches to color catalogization and organization.
3) Students will understand how the way a compound interacts with radiation determines its technological application (i.e., colorant, brightener, sensitizer, absorber, scattering/screening agents).
4) Students will become familiar with the essential color matching experiment and will adopt the related theory of color matching functions, tristimulus values and derived chrimnatic coordinates. Students will undestand the concept of colour difference, its various forms and significance for technology.
5) Attendeeds will learn the good laboratory praxis of spectroscopis and colorimetric measurements. They will understand the significance of measuring conditions (geometry, reflection, polarization, base support etc.)
6) Attendees will learn about the basic technology principles of colour reproduction and characterization of light sources.
