Principle of Detection Stable and Powerful Detection for Inline Use The E3MC detects colors by making use of the fact that the reflec- tion ratio of a primary color (i.e. red, green or blue) reflected by an Stable detection is assured with a threshold object varies with the chromatically of the object.

Discriminating Delicate Color Differences Color Chart The detection level indicators are lit according to the degree of conformity between registered and detected colors. Deli- cate color differences are discriminated by setting the thresh- old to a superior level. (Fine discrimination is expected.) Sensor errors that may be caused by minor tint differences or dirt retention are prevented by setting the threshold to a lower level.
