30What About White Opacity? Can Surface Screens Using Flat Top Dot Technology Improve Opacity With Solid Whites?
31PurposeGain an understanding of the optimum plate durometer, cushion tape and surface screening parameters to maximize white opacity readings at high press speeds.

35High Values Of Plate And Tape Contrast Ratio Function
36Values Ranked By Surface Screening Value These are the highest opacity readings found for each of the SS parameters. As you can see there is a high range of aprox 2%. The dark blue bar is the non SS patchContrast Ratio Function
37Second TestEvaluate opacity using lower anilox volume and Flat Top Dot surface screening parameters.Will there be a greater differences in opacity using lower anilox volumes?Will this reduce ink consumption while delivering acceptable opacity?

41Coating Weight and Opacity Contrast Ratio Function
42ConclusionsFlat Top Dot technology allows for a greater level of detail at the surface.Surface screening reduced pinholes and increased the opacity.Increasing the modulus of the cushion tape increased opacity.
43ConclusionsHigher opacity levels were achieved using surface screening allowing for the use of lower anilox volumes and potentially eliminating the need for a double bump.
