Spot colors can be manually fine-tuned to meet special requirements or to improve the visual match. The spot color tuning is performed by means of a visual chart which displays several variations of a selected spot color. After printing the chart, you can decide which patch fits best, select the patch and have the software adjust the spot color values automatically.
