Ive used the correct pantone colours but when I compare my artwork with other materials it still looks a different colour shade. Why?
When printing in spot colours (pantone) there is only one ink pot used, whilst the CMYK process will use four coloured inks (Cyan, Magenta, Yellow and Black) because of this matching colour will not be exact. You will need also notice that printing on different paper stock can also affect the final output and even applying a machine seal will affect the final results.
