Descreen
The Descreen tool lets you remove moiré patterns in the scan 
process. Moirés occur when you scan a screened original (mostly 
reflective materials, such as pictures from a newspaper or 
magazine). These patterns appear to the naked eye like a series of 
grids of dots or as shown in the example below.
