How to automate selection of Pantone HUE according to RGB color?

Question

Design

A corporate identity is being developed. Usually in RGB. Sometimes an additional task is to select pantones that are as similar as possible to the original colors. It is rare to find a good pair of source code. But it often turns out that a certain shade of a particular pantone is very well suited. However, Adobe packages, for example, automatically convert only to one or another pantone, ignoring its shades (fill percentage).
Is there a solution?
Super-task: automatic search not only for a suitable shade, but also for a mixture of pantones (for example, pantone A 100% + pantone B 65% = original color).

Answer 1

Pantones are not originally designed for printing with a raster or fills other than 100%. Their whole point is to print with the finished spot color.
If you really want to, then you can experiment, of course, but it will still be shamanism with an unpredictable result. And especially not algorithmic. Only the method of color proofs and errors. And even if you choose the right combination, it will only be valid for a specific printing house, process technology and paper. It is necessary to go to another printing house - the recipe can be thrown away.

Answer 2

RGB translate to nearest Pantone for example on this website . But it's kind of irrelevant.
In a good way, take Pantone fans and select those suitable in nature. Under different lighting - daylight, office energy-saving lamps, by candlelight. On different types of paper.
70% color printed on white glossy paper and matte yellowish paper looks different. Coated with varnish and uncoated - too.

Answer 3

First, RGB colors must be converted to CMYK colors through the appropriate color profiles (for example, sRGB in Coated FOGRA 39 or ISO Coated V2 ECI), because Pantone does not directly compare the RGB coordinates of schemes and pantone sets for printing. Then, through the Pantone Color Bridge, match the CMYK colors to specific pantones. However, with any method of matching colors, the output will only be solid pantone colors and not their combinations with a certain percentage, because pantone is already a spot color in essence.
