Customers often see the paint quality and condition of the machine as indicators of overall care and maintenance. How challenging is colour matching with different paint application methods and the various house colours of manufacturers? Kehr: Colour matching between different paint application methods as well as the specific house colours of manufacturers is a great challenge. Especially with precise house colours, such as corporate identity colours according to RAL or Pantone, minimal deviations are critical as they could impair the brand image. Therefore, coordination requires highly precise measurement technologies, such as spectrophotometers, and close collaboration with specialised paint manufacturers.
