Reproduction ratio of colors contained in a table

Here is how you can define the spot colors that you will be able to reproduce on your printing system.

Are your customers asking you if you are able to reproduce this or that PANTONE on your printer? 
Currently, it is difficult for you to answer them without performing tests that will waste time and material.
With Coraye, in just a few clicks, edit a report summarizing the list of colors that you can reproduce with certainty, to meet your customers' demands.

To obtain this report, you will need only two elements:

The color list appears with the benchmark Lab values and the Lab values you should get when you print.

You can set the tolerance value of Delta E, H or Ch.
That is, you can decide from which colorimetric precision step, the reproduced colors will be acceptable.
I recommend a Delta E = 2 The values of Delta E are expressed in Delta E 2000.

To display the list of colors that will fall outside the tolerances you have set for yourself, you can sort the results in descending order.

In the search bar, it is possible to filter colors.

By hovering over the colors in the list, you can bring up the Name, RGB or CMYK value, and Lab value of the color you will get when printing.

Please note that the RGB or CMYK values can only be used if the profile used is a conversion profile. and not a media profile.
