Using Colour Measurement Instruments For Natural Foods

Early colour measurement applications tackled both simple and complex objects Automotive and Decorative coatings soon benefitted from the invention of reliable Colour Measurement Devices and have by and large retained the same protocols for the last 60 years. Recent inventions in that sector enhance rather than reform older practices. On the complex side, Textile and […]

Why Wait !?

The Global Covid19 phenomenon has taken us all by surprise and the repercussions will become clear over the coming months.

SCE vs SCI – When to use which?

Specular reflection is the mirror-like reflection of light waves from a surface. In this process, each incident ray reflected at the same angle to the surface normal as the incident ray, but on the opposing side of the surface normal in the plane formed by the incident and reflected rays. The result is that an […]

How much Delta E* is visible?

Quality Control is all about numbers. As technology becomes more complex, tolerances become tighter and harder to manage   Old School methods would take the Mass of an object, say a 500 g block of butter, and set the tolerance to plus-minus 5 g. As long as a batch sample mass was between 495 to […]
