Description

This course is designed for all those working in the field of colour science but especially those working in the: paint, ink, plastics, textile, cosmetic and food industries. The course will have a strong practical emphasis, enabling delegates to:

  • Understand how to characterise the optical properties of the following materials:
    • Opaque: plastics, textiles and paints
    • Semi-transparent: printing inks and foodstuffs
    • Transparent: 4 colour inks
    • Optical filters and clear liquids.
  • Manage the preparation of calibration panels for use in colour match prediction databases.
  • Develop systematic improvement in the accuracy of match prediction databases

Practical exercises using viewing cabinets, colour measuring equipment and software provide the link between theoretical and practical aspects of colour, its control and characterisation in numerical terms.

Who Should Attend

This course will be beneficial for those who wish to build on the 'Colour Measurement and Colour Control' course or who are already familiar with colour measurement for quality control.
