One common practice is the use of barcode -recognition technology: Record the maintenance history. For the latter, the scanned result is a non-compressed RGB image, which can be transferred to a computer’s memory. Instead of using the scanner’s true optical resolution , the only meaningful parameter, manufacturers like to refer to the interpolated resolution , which is much higher thanks to software interpolation. The file size can be reduced for a given resolution by using “lossy” compression methods such as JPEG , at some cost in quality.
