part harmony, while identifying colour issues before production begins by applying to a virtual replica that includes different surfaces, curves and edges. A spectral and texture data audit trail is established for formulation and production quality control to ensure consistency through the process. X-Rite believes that there are more opportunities
to be exploited to help plastics producers and processors to better understand how their process is affecting the colour and appearance of finished products, and to help brand owners improve how they specify and control. “Further expansion of Pantora software with the MA-T12 device, will include metrics to quantify the variance’s we visually perceive,” says Adby. “This removes the challenge of subjective visual assessment, which has always been difficult because it has been impossible to determine if variance was coming from colour, gloss, translucency and texture or a combination of these.”
Many plastics industry customers have found
that quality control (QC) through colour measure- ment is a convenient way to ensure that their production process is stable and within specifica- tions, according to Konica Minolta Sensing. As
such, the company says it is seeing continuous demand for both hardware and software solutions related to colour measurement in the plastic industry. And with colour tolerances becoming tighter, expectations towards the measurement devices are also increasing.
Consistent targets “Of course, a device must provide you with the same measurement value over time,” says Ewald Rath, Konica Minolta’s Technology Manager Colour & Appearance. “However, it must also provide the
