Is there anything different I need to do to print PANTONE PLUS SERIES spot colors?
No! The PLUS SERIES colors are printed using the same 14 Basic Color inks as the PANTONE MATCHING SYSTEM. One new difference - and advantage - is that all the new solid colors are printed at a unifirm ink film thickness, which makes them easier to match on press. This saves time and money while ensuring color accuracy. Note: we did add 336 new colors in April 2012, and four additional base inks, bringing the total to 18 base inks. However, the basic printing process does not change.
