Hi folks, I need a bit of help trying to convert a colour to CMYK. I don’t have the relevant Pantone to CMYK book so just went with switching the colour to CMYK in Illustrator. Have then output a proof and the colour (320) has come out really blue on two different printers whereas on screen it’s still the correct shade of Turquoise. Does anyone have a Pantone Book and can give me the correct reading? I’ve had a look on t’internets and am getting all kinds of different numbers back. Thanks in advance.
