The closer the Delta E is to 0, the smaller is the difference between the colors. If the Delta E is higher then 2, the human eye recognizes the difference between two colors.
Delta E Finder is able to compare two kind of files:
.spc : Measured color with a spectrophotometer and with spectral data included
.spot : Color export from a color table or directly created with Lab values only.
In this tutorial, we are going to compare a Pantone sample from a printed swatch book with a value from a digital swatch book.
In this example we will use a PANTONE spot color table.To use this PANTONE spot color table you must have the licence to use it.
To import a color table, you just need to drag & drop the file into the left column.
You just need to write the PANTONE number into the "search" area then you have to drag & drop the displayed color from the color table to the left column.
The last step is to select the reference color and to drag & drop the color to compare into the Delta Finder area.
Delta E value will appear below
Printed PANTONE Swatch books are less accurate than a digital swatch book because a printed swatch book don't have absolutes colors. The measurement with a spectrophotometer is more accurate and is not disturbed by a visual comparaison in a wrong condition (a wrong illuminant e.g.)
