I was wondering two things:
01_ How do mixed ink swatches work in real life (in offset printing)? Let's say I made a mixed ink swatch with 2 Pantone colors. Does the printer premix the 2 Pantone colors before printing, or does the 2 Pantone colors overprint on the press (depending of the pourcentages of each Pantone color)?
02_ Can I do a mixed ink swatch in Illustrator? If so, how?
Thank you so much! Have a nice day!
Mixed inks are easy to make, but difficult to proof without going on press and making a press proof. There's no way to accurately soft proof on screen because there are no color management profiles for Pantone tints and mixes, so you have to be careful that the design doesn't rely on accurate color.
