Color Shift Differentiation

Challenge

A Fortune 500 consumer products company sought a device to automate the measurement of very small color shifts.

Solution

A VNIR camera-based scanning system was developed in conjunction with color conversion software. The dedicated software was able to identify the L,a,b values of every point in the image, calculate the exact color coordinates of dozens of predetermined areas and report those along with the color shift from a predetermined sample. With the ability to measure many small objects at the same time and calculate precise color coordinates and color shifts with arbitrary shape masks (the shapes of which could be saved and reused), the company increased the productivity of their laboratory staff and achieved more reproducible results for the expected small color shifts for its pre- and post-treatment sample sets.
