When printing digitally, any spot colors included in your job will be converted to the process, color equivalents (CMYK) used by the imaging device. As a result, these match colors may shift noticeably.
If you need to reproduce spot colors accurately, for example to print the colors of your company identity consistently, you can check whether the specified match colors have close enough process color equivalents by consulting the Pantone® Color Bridge swatchbook.
A strong advantage of digital workflows is that you can proof your job economically on the same machine that will be used to run it. This lets you judge any color shifts with no doubt about the results you can expect.
