When you have measured a color with Spot Reader, may be do you need to convert you color into RGB, CMYK or Lab. Color finder do that and also display the Delta E values after the conversion to tell if the color is reproductible.
For example, you can use a paper profile to do the conversion, and if the Delta E is close 0, that’s means your color is reproductible. So, if your Delta E is more than 2, that’s means your color is not reproductible.

Or may be do you need to know what is the nearest color from a guide book like PANTONE, RAL or a custom guide book.
Color finder do that and you give the accuracy (Delta E) between the reading color and the closest color from your guide book.

1 ) How to use Color Finder to convert a color with an ICC profile 

Click on the third pictogram into the lower bar on the right

The Color Finder window will appear.

Now you can get a color from Spot Reader or load a .spc file from  your computer, with a click right into the lower bar.

Select files to load into Coloris.

For example, I’m selecting two icc profile (AdobeRGB1998 and Isocoated_v2) and two .spc files (2 previously measured Pantone color with Spot Reader).

And files will appear into the lower bar.

Now, drag and drop a color .spc from the lower bar to the upper right area (rectangle with an orange border) to select the color.

Then drag and drop an ICC profile from the lower bar to the Profile area (rectangle with a red border) to select the profile to convert into CMYK or RGB, depending on kind of profile.

Your color is automaticaly converting into CMYK or RGB, depending on it color space.

You get also Lab value after the convertion , and the delta E between the original Lab value and the Lab value after conversion, that will say if the color is reproductible or not into the color space used to convert the color.

In my example, I measured a PANTONE 106 C and I converted it with a CMYK profile (ISOcoated_v2_eci.icc) to know if this Pantone is reproductible into the CMYK space . In our case we can convert it into CMYK without color difference, because the delta E is close zéro.

An other example: you can use a paper profile to do the conversion, and if the Delta E is close 0, that’s means your color is reproductible. So, if your Delta E is more than 2, that’s means your color is more or less reproductible.

 

2 ) How to use Color Finder to Find a color into a guide book

First, you have to select your guide book with the green « Select a file » button.

Then select the .json file contening the guide book.

Now, drag and drop a color .spc from the lower bar to the upper right area (rectangle with an orange border) to select the color.

The closest color from the guide book will appear into the case « NEAREST SPOT » and the Delta E between the mesured Color and the color found will be displayed on the right.

This function can be usefull to know what is the closest color into a guide book like RAL or PANTONE.

But it can be also usefull to control color into a Quality control process.

Or you could created your own vinyl color guide book, to find the right color into sign application.
