Principles of Colour and Appearance Measurement

Informationen zum Autor Dr. Asim Kumar Roy Choudhury is presently working as principal, KPS Institute of Polytechnic, Belmuri. He retired as Professor and HOD (Textile) from the Government College of Engineering and Textile Technology, Serampore (W.B.), India. He has over 30 years' experience in textile coloration and finishing in academia and industry, and has written numerous papers and several books on the subject, including the recently published two-volume work Principles of Colour and Appearance Measurement. Klappentext Understanding how consumers perceive colour, how colour can be measured and managed to match consumer expectations is both critical and complex. Written by one of the foremost authorities in the field, this major two-volume work addresses the key topics required to understand the issues and manage colour effectively. The first volume addresses how objects appear to viewers and how they perceive colour. It also reviews the major types of instrumentation used to measure colour. This book will be a valuable reference for a range of readers including designers, colour technologists, colour quality inspectors, product developers and anyone who uses colour in their work.

Klappentext

Understanding how consumers perceive colour, how colour can be measured and managed to match consumer expectations is both critical and complex. Written by one of the foremost authorities in the field, this major two-volume work addresses the key topics required to understand the issues and manage colour effectively. The first volume addresses how objects appear to viewers and how they perceive colour. It also reviews the major types of instrumentation used to measure colour. This book will be a valuable reference for a range of readers including designers, colour technologists, colour quality inspectors, product developers and anyone who uses colour in their work.

Zusammenfassung
"These volumes have earned their place on the well-equipped color science bookshelf, both for their up-to-dateness compared to the classics, and completeness of coverage across a wide range of topics." --AATCC Review
