Harmony 2

You know it when you hear it. Musical harmony is the result of simultaneous notes or chords blending together to create a sound that is pleasing to the ear. The combination of different notes played or sung simultaneously creates harmonization. Musical groups such as The Doobie Brothers, Queen, and the Zac Brown Band perform harmonization with style and clarity.

Harmonic sound is enjoyable to hear.

Visual harmony is a different slant on the same idea. More…

Sample size and shape are important considerations when selecting a color or appearance instrument. Instruments typically have a fixed aperture size, and samples must cover the entire aperture in order to be measured accurately. More…

Every year or so, it comes time to send in your instrumentation to be calibrated per your quality control protocols.  You receive your instrument back along with a traceable certificate.  Or, you may even have a Field Service Engineer visit you on-site to calibrate and certify your instruments.  But, that certificate that you hold in your hand, that you file away, what does it mean for you?

Using the cloud-runner for Process Modification Verification Reply

Automotive OEMs are constantly looking for ways to make manufacturing more efficiently while producing a better vehicle. Use of the cloud-runner can provide valuable feedback when evaluating new paint processes and paint formulations for the presence of mottle or striping. More…

Quick and Inexpensive Color Measurement of Metal Surfaces Reply

Metallic surfaces can be difficult to quantify for color.   The color measurement varies dramatically with the angle that you view it. For this very reason BYK-Gardner developed the BYK mac i multi-angle color instrument. It measures the color and sparkle of the metal and other effect surfaces at 6 different angles and even quantifies how much sparkle there is on the surface.

However, this is just too much information for basic color quantification of bare metals, building materials or inexpensive household or automotive accessories. More…

The BYK-Gardner color-guide and spectro-guide contain many common and useful color indices. One can change the instrument to most of the widely used color systems: CIE, Lab (hunter), Spectrum, XYZ, Yxy, FMC2 and others. You can also change the instrument to a number of different indices to measure color difference, whiteness, yellowness, opacity and strength. But nowhere in these lists are any indications of the LRV of the color you are measuring. More…

A recent addition to the spectro-guide’s list of color indices is the Grey Scale. The Grey Scale is one of the most important tools to evaluate color shading and staining, and is widely used by the automotive industry to measure the fade of the fabric in a vehicle’s interior. It is based upon both ISO and AATCC specifications. More…
