Display of the La/Lb diagrams
The two graphs show the color gamuts in the L*a*b* color space viewed from the side, parallel to the lightness axis.
In the top graph, the color space is shown in the direction of the a* axis, that is from green to red, and in the bottom graph in the direction of the b* axis, i.e. from blue to yellow.
The color gradations, right and left, show the influence of the color lightness.
From the diagrams, you can assess the depth resolution of a printing process in the color space and its size and which colors can be displayed.
Display
To the right of the diagram, you can define various settings for viewing the color space:
•"Reference data", "Comparison data": You can select the color to show the data (dots and cobweb) of the reference and comparison data. The following colors are set by default:
·Reference data: Blue
·Comparison data: Red
•"Dots": Display with or without measuring points
The small dots that can be seen are the color values (locations) of all the patches measured in the test chart or control element.
•The green circles/ellipses mark the tolerance range in the process standard for each process color. This graph shows the size of the color space and the position of the process colors in relation to the tolerance range.
•"Cobweb": Only the outlines of the color gamuts are shown in the La or Lb diagram with this function.
•You can print the view as a log (see General Information about Printing).
