PMS SPOT COLOR
Be careful to use the same spot color throughout the job. PMS123cv and PMS123cvu will not print out as the same color. You must be especially careful when placing eps graphics with embedded color, use the same PMS color to define other parts of your job.
Monitors vary widely in how they display colors. What you see on your monitor will vary from the final printed piece. Spot colors will match the PMS book but not necessarily your screen. On 4/color process, a final color proof is recommended.
