Stripes appear on scan of publication
Cause: | Moiré effect from scan of publication at high resolution (print |
| screen lines highlighted by optical interference, producing |
| striped patterns). The appearance of this effect is dependent |
| upon particular combinations of screen line densities and |
| scanning resolutions |
Solution: | Rescan at different resolutions (See the CanoCraft |
| Guide electronic manual) |
