I need to assing my design a specific spot color with certain lab values with decimal places, but Illustrator rounds up the values as soon as I input them. Is there a quick fix, with Illustrator settings or how can I make it work?

    Does it make a visible difference? I suppose that a spot color is mixed by the printer according to the Lab values and that the values in Illustrator are only used for preview.

    I think there is a difference, in preview the color looks at least similar, but after printing client claim that the tone aint right. They game me lab exact values, for their spot color which it should ...seems that illustrator rounded those values, and the result aint what it shpuld be.

    Rounded, from what, to what? Every app is going to round to a certain number of decimals, and this won't necessarily match. That's just maths, nothing is broken. If the value actually changes, rather than being shown rounded or truncated to a fixed number of decimals, something may be wrong.
