I'm new at working in Illustrator and I'm using spot colors for screen printing (new at that too). I changed Pantone Black C into CMYK and then into a spot color. The CMYK is 0/14/39/98 not 90/80/80/100, the ratio that makes pure black in other jobs I've done for full color print. Am I doing the switch to spot color correctly to prepare the design for silk screening? Will it end up printing as Pantone Black C? And if I do the other colors the same way (changing to CMYK and then to spot) will they end up printing true to the solid/coated numbered colors in my Pantone book?
