What does resolution mean when scanning?
The resolution setting in your scanning software, measured in dpi (dots per inch), controls the amount of detail captured in your scans. Increasing the resolution raises the amount of detail captured but comes with the following disadvantages: Larger file sizes.
Is higher resolution better for scanning?
The quick answer is that higher resolutions lead to better scans for reproducing your images. 600 DPI scans produce much larger files but help ensure every detail in your print is recorded in digital form. If you want files that are easier to work with, 300 DPI scans would be a better choice.
What does resolution dpi mean on a scanner?
dots per inch
DPI, or dots per inch, is a measure of the resolution of a printed document or digital scan. The higher the dot density, the higher the resolution of the print or scan. Typically, DPI is the measure of the number of dots that can be placed in a line across one inch, or 2.54 centimeters.
What resolution do scanners use?
Color images and documents are the most common scanned objects. Color photographs should be scanned at 600 DPI, however; scanning at a DPI of 1200 will ensure archival-quality photographs. Scanning above 1200 DPI is overkill and not necessary. When scanning for the web, color photos should be scanned at 300 DPI.
