COLOR QUALITY CONTROL SYSTEMHEADLINE

This is a system for determing a color difference between a target color and a trial color, a color differece between lots and whether a product passes or not.

In today's color quality control,especially of Metallic and Pearlescent Color that color expression is sophisticated and diverse, not only the numerical value such as color differnce (DE) and Delta L*, a*, b* but also numerical value and graph managing sparkle and graininess are necessary.

CI-Navigator provides a variety of graphs including 3D-graph and trend graph of color numerical value and the image parameter. These graphs are useful for the color quality control of the color with complicated optical properties such as Metallic and Pearlescent Color. In addition, it is easy to compare and evaluate a trial color with a target color from various viewpoints by rotation of 3D-graph and changing it's scale.

**Delta L,a,b* Trend Graph**

olor numerical values such as DE and Delta L*, a*,

　b* are displayed as a list and are displayed by

a 3D-graph and/or a trendy graph, therefore it is

　possible to control precisely the quality of color.
Calculated colors which includes hue, lightness, chroma and feel are displayed in order therefore it

is easy to visually estimate them .

SL,SC,SH Parameter Simulation

Image Parameter Trend

Varietly of graphs of not only chromatic parameters but

also image parameters are

provided and it is possible to control color quality from

　various viewpoints.

Tolerance Setting

Pass/Fail decision is clear at a glance by setting tolerance in 3D-graph.
