The color around letters is
detected as a mark.
Predetermined colors are
detected as marks.
Even similar colors are accurately determined using the R• G• B ratio.

Color mode
High precision mark color discrimination
The color mode on the LX-100 series utilizes all 3 R• G• B LEDs to determine the R• G• B ratio of the mark color. The built-in 12-bit A/D
converter enables high precision 1/4000-resolution judgments. The figure below is a graphic description of this process.

All 3 R • G• B LEDs light up and high precision mark color
discrimination occurs using the R • G • B reflective light
ratio. This function enables effective detection of films with
patterns around the area of the mark.
