I have used colored dotted cell strokes with alternating colored fills in a table. Where the strokes are adjacent to or overlap the fills, I can see that the strokes actually have a white (paper-colored) "background". That is, between the dots I see white, instead of the fill color; it's as if there was the fill, on top of it a paper-colored stroke, and finally topmost, the colored dots.
Why is this? Can I change it -- if I want just dots on whatever the background happens to be?
The strokes and fills are tints of the same spot color.
Oh, it was "Paper"! Changing it to "None" fixed it. Thanks so much, Jongware! Somehow I have managed to ignore this setting.
