Scanned image is of poor quality
Is the original a second generation photo or picture?
Reprinted photographs, such as in newspapers or magazines, are
printed using tiny dots of ink that make an interpretation of the original
photograph; thus, the quality is dramatically decreased. Often, the ink
dots form unwanted patterns that, when scanned and reprinted or
displayed, can be detected. If the following suggestions do not
provide a solution, you may need to use a better-quality version of the
original.
●
Try to eliminate the patterns by reducing the scanned image size.
See “

settings through the printer properties (driver). See “
