Newspaper Scanning
When scanning a picture from a newspaper we have 2 problems:
1. The printing resolution of a standard newspaper is very low - 80 PPI.
2. Newspapers are printed in an "Offset" technology which means the picture is made of rather big and visible spots.
If you scan a picture from a newspaper without obeying very certain rules the final result will be bad.
In order to get a nice result from a newspaper scan, we recommend:
1. Always to scan at a resolution of 170 PPI if you have a option of 170. If you don't have it you can choose 150 or 200 PPI.
2. In most of the scanning softwares you'll be able to find an option called "Descreen". Activate this option, its purpose is to decrease the effect of the grid caused by the "Offset" printing.
If you can't find the "Descreen" option or if you used it and you can still see the grid, you'll be able to find in most graphic softwares a tool which will take care of this problem. Sometimes you'll be able to fine such a tool under "Moire Pattern Removal".
