Right. I mentioned the screentone. They are notorious for moiré effects. In fact, in its heyday, Japanese manga artists would use the moiré patterns for dramatic effect. I don’t know how old you are, but when watching BW movies on an NTSC television, moiré effects occurred regularly because of the patterns on the clothes that the actors were wearing.
But I’d rather not see a rainbow dancing across my black-and-white manga. LOL I imagine the effect would be either pronounced or reduced depending on the screen size in relationship to the image being displayed. I’ll have to play with that rainbow toggle somebody mentioned above.
