Best DPI for Colour or Greyscale Scanning

Best DPI for Colour or Greyscale Scanning

26/04/2024 Information 0

The best DPI (dots per inch) for color or greyscale scanning depends on the intended use of the scanned image. Here are some general guidelines:

  1. For web use: If you plan to use the scanned image on a website or social media platform, a resolution of 72-150 DPI is usually sufficient.
  2. For printing: If you plan to print the scanned image, you should use a resolution of 300-600 DPI to ensure a high-quality print.
  3. For archival purposes: If you plan to archive the scanned image for future use, you should use a resolution of at least 600 DPI, preferably 1200 DPI or higher. This will ensure that you have a high-quality digital copy that can be used for printing, sharing, and other purposes in the future.
  4. For text documents: If you’re scanning text documents, a resolution of 200-300 DPI is usually sufficient, as the focus is on the content rather than the image quality.

It’s important to note that higher DPI means a larger file size, so you’ll need to consider the storage capacity of your device or cloud storage before deciding on a resolution. Additionally, if you’re scanning a fragile or delicate item, such as an old photograph or artwork, it’s recommended to use a lower DPI to avoid damaging the original item.
