You can use two methods to enhance spot tint colors. You can use the spot tint libraries that you created for selected spot color libraries. Alternately, you can provide information that the software can use to calculate the spot tint colors for the selected spot color libraries.

Requirements: Spot tint libraries must exist for the selected spot color libraries, if you are using spot tint library method.

Both methods let you choose whether to simulate the highlight bump or highlight minimum dot seen in flexographic printing. When printing white content with the Epson Stylus Pro WT7900 printer and white ink and using a CIE L*a*b* color library, select Calculate All Spot Tint Colors. For L*a*b* color libraries, do not select Use Spot Tint Library because the Opacity option is not yet supported.
