Hello

Could someone help us with this conversion?

We have artwork CMYK  +  Pantone (could be one or many).

Now we want to convert it to CMYK+ORANGE+VIOLET values.

I have theese values in csv.

each pantone, separate file -->number of pantone.csv

Conversion should work with % value of pantone too.

As said before, you cannot do that in Illustrator.

What kind of RIP software is processing the art files? Is it an app that came included with the printer? I would hope that is the case since orange and violet are unusual for additional, gamut-extending ink colors. Most six-color large format printers have light magenta and light cyan inks (in addition to the CMYK inks).

 

Either way, the RIP software chooses how to apply those added inks, especially when simulating Pantone spot color ink values. I can't just add additional light cyan and light magenta color channels to an Illustrator document. I have to use the Pantone swatches. The RIP software should have its own built-in Pantone color libraries and CMYKOV formulas for those spot colors.

These Indigo presses. with multiple inks can simulate many Pantone colors and use the additional inks to add to the CMYK  gamut. The rip does the conversion.

You cannot do that in  Illustrator, the rip does the conversion from RGB to CMYKOV

Do you have a printer with these inks?

If so, the conversion is done during printing.

Hi @grafik2_5837, just putting aside the question of converting to CMYKOV... can you even specify a color manually as CMYKOV in Illustrator? I did a quick google of "CMYKOV Adobe Illustrator" and nothing relevent appeared. Maybe you can't do it? Or need a third-party plug-in?

 

EDIT: you could create a spot color of "Orange" and "Violet", then add a second and third fill color (all overprinting), but you probably couldn't automate this via scripting because the scripting API only provides access to the single basic fill and stroke, not the extra ones.

 

It would be good to post a sample document (save as illustrator editable pdf to post here) showing (a) before conversion and (b) after conversion, so we know what exactly you want to achieve.
