Color
Advantages DrawbacksCan make some older documents easier to read
Color will make for a larger file size.
Can preserve the information of the original – for example a color graph will still be in color.
Color can be difficult or expensive for the user to print.
Color can make some low-contrast black and white documents more readable.
A color scan may appear to decrease the overall contrast of a black and white document making it more difficult to read.
