Choosing a scanner depends on your specific needs. If you scan receipts or documents, the scanner in your all-in-one printer may be all you need. If you are a graphic artist or photographer, you may need a photo scanner. If you run an office, you may benefit from a document scanner.
How Color Depth Affects Image Quality ASAP
Scanner resolution and color depth are important factors to understand when considering a scanner purchase. Here’s a look at what these terms mean and how to assess your scanning needs to buy the right device.
In scanners, optical resolution refers to the amount of information the scanner can collect in each horizontal line. In other words, resolution is the amount of detail a scanner can capture. Resolution is measured in dots per inch (dpi). Higher dpi means higher resolution and higher quality images with more detail.
The typical optical resolution in multifunction printers with scanning capabilities is 300 dpi, which is more than enough for most people. The resolution of heavy-duty office document printers is often 600 dpi. Optical resolutions can be much higher in professional photo scanners, for example up to 6400 dpi.
