The two images were scanned at different resolutions, but there
isn't much difference in the printed result. This is because all
printers and presses have their own maximum resolution. It's also
because the final size is so small that anything over 150 ppi is really
unnecessary.
What is a scanner
A scanner is a device that captures an image and converts it into a
digital form that your computer can display, edit, store, and output.
The image may be a photograph, page of text, drawing or
illustration, or even a relatively flat, three-dimensional object such
as bolt or fabric. In practice, this means you can use your scanner
to do the following:
●
Incorporate artwork or photos into documents
●
Scan printed text into your word processor and eliminate
retyping
●
Scan faxed documents into a database or word processor
●
Add images to multimedia productions
●
Integrate visuals into presentations to make them
communicate more effectively.
With a basic understanding of how scanners work, the types of
scanners available, and what they are capable of doing, you can
improve the quality and efficiency of your work.
Type of scanners
Scanners can be classified into three general types:
●
Flatbed scanners, which are used to scan photographs or
prints. Flatbeds have a glass surface on which the materials to
be scanned are placed.
