Color Story: Examples of Color Tolerance

The tolerance range of colors can be expressed in terms of color difference values.

When the measured tristimulus values XYZ are converted to UCS (Uniform Color Space), they can be displayed in L*a*b* coordinates, allowing for the comparison of the magnitude of perceived color differences based on the distance between the coordinates of two colors. In other words, the acceptable range of colors can be expressed in terms of color difference values. We will introduce examples commonly used in JIS standards and various industrial sectors. 【Examples of Color Tolerances (Excerpt)】 ■ Non-evaluable area - The range of perceived color differences falls within the margin of error, even with specially calibrated color measurement instruments, making it indistinguishable by humans. ■ Identification boundary - The range of perceived color differences is within the reproducibility range of sufficiently calibrated color measurement instruments, where trained individuals can reliably identify the limits. *For more details, please refer to the PDF document or feel free to contact us.*

Color Story: Color Bias Determination Method

You can control the color while viewing the color deviation determination diagram.

The color deviation determination method is a convenient color management technique used when you want to quantitatively assess the deviation of the sample color from the reference value, the color difference between the previous lot and the current lot, and the direction and positional relationship of the sample color deviation relative to the target color. This method is similar to the display of an aircraft's automatic landing guidance system. 【Steps for the Color Deviation Determination Method】 1. Set the measuring instrument to the color deviation determination display. 2. Measure the target color. 3. Measure the sample color. 4. Determine the direction and amount of color deviation. 5. Summarize the results of the color deviation determination. *For more details, please refer to the PDF document or feel free to contact us.
