More challenges Changing material
technologies create further challenges for colour measurement and communi-
cation. Special effects, such as pearlescence or metallic effects, present a challenge
because colour differs depending on the viewing angle and lighting. The new, portable
The BYK-mac i measures multi-angle colour as well as sparkle and graininess
BYK-mac i spectrophotometer measures multi-angle colour as well as sparkle and graininess for total colour matching; it also detects and quantifi es fl uorescent light in the visible range, says Anita Fehr, product manager for colour at BYK-Gardner. The increasing use of more recycled material in
colour-critical applications has created new challenges in how to control colour when incorporating recycled

materials that have colour variability, notes Ken Phillips, market development manager at HunterLab. Business trends also affect colour-control operations. “Consolida- tion and reductions in workforce make today’s operator a multi-faceted employee with increased responsibilities in many areas of production, rather than an expert in any one area of the process. This makes keeping up with the necessary skills and knowledge diffi cult, especially in the area of colour management, which often times requires a bit of ‘black magic’ to be successful,” comments Phillips. He adds that this lack of expertise is further driving the need for automation as a means to reduce human error and improve consistency and reliability in the manufacturing process. “These automated solutions for colour QC and colour control are becoming more widely accepted due to improved performance, reduced system costs, reduced total costs of ownership and attractive ROIs,” he adds.
On-line colour measurement Tools for taking the next step to on-line colour measure- ment and control of the compounding process have made recent advances. These systems include the
