The resolution of the scan is unnecessarily high (usually applied to scans with a 600DPI or higher). The screening dots are large and images tend to be very blurry.

Printing resolution varies with the quality of the item/publication, but it doesn't have fine details over 300DPI. Images should be scanned above 300DPI to prevent moiré, but then downscaled some time during the editing process.
