Instructor: S. Kendall Scott and Allen Brown
The primary objective of this course is to provide a solid foundational understanding of visual and instrumental color assessment for industrial color production and control. This is an introductory course in which the student will gain a thorough appreciation for the three essential elements of color – light source, object, and observer – and how each of those impact visual and instrumental color assessment and control. This objective will be accomplished through a good mixture of presentations from industry experts and hands-on projects, while working in teams. The focus of the first day will be on visual assessment of color and the second day on instrumental assessment.
Who should attend?
The course is designed for personnel in industry who find themselves responsible for color in their daily work but have not had formal training in the fundamentals of visual and instrumental color evaluation. This includes technical lab and quality control technicians, supervisors, and managers, designers, color matchers, salespeople, and marketing specialists. Students will come from a variety of industries, making several different kinds of materials, such as coatings, plastics, and textiles, for automotive, aerospace, architecture, appliances, and other materials and devices.
