What scanning resolution should we really use? The scanner can only scan each horizontal scan line at its optical resolution, like 600 dpi or 1200 dpi, however the scanner is rated. To achieve our desired final size, say 175 dpi, this image must be resampled, from say 1200 dpi

Fair Quality is based on 170dpi of image resolution, Good Quality is based on 260dpi of image resolution, Great Quality is based on 300dpi of image resolution.Larger printing may be possible by resampling an image. The charts below relate to prints scans. The first chart is for 300 DPI print scans.

I don’t think we’ve had a lot of cases when we had to go below or above. The 200dpi resolution provides sharp details for general reading or even printing. Colour photographs are often scanned at higher resolutions to capture their detail – typically from 600 to 1,200 dpi, with the higher resolution used for the best archival images. However, for web use or to save hard disk space, 200 dpi is the standard choice of most businesses for most colour images and colour documents. A typical flatbed scanner has a CCD element for each pixel, so for a desktop scanner claiming a horizontal optical resolution of 600dpi (dots per inch) – alternatively referred to as 600ppi (pixels per inch) – and a maximum document width of 8.5in there’ll be an array of 5,100 CCD elements in what’s known as the scan head. The scanner can only scan each horizontal scan line at its optical resolution, like 600 dpi or 1200 dpi, however the scanner is rated.

With the Perfection V600 Photo, in December 2009, Epson introduced a flat bed scanner with a transparency unit into the market replacing the previous model Epson Perfection V500 Photo. The scanner is of a successful and modern design that also looks good in a stylish office or at home.

You can compute the optimum scanning resolution with one of the following two formulas: minimum scanning resolution = lpi x 1.5 maximum scanning resolution = lpi x 2 In most cases you will find that the minimum scanning resolution produces quality images. 4800 x 6000. Conclusion: Computer and video related use is not as demanding as printing or archiving. We recommend you go with 2000 DPI film scans and 600 DPI print scans for computer and video related use.

The producers of the flat bed scanners that in former times worked with values between 300 and 600 dpi, declare today resolutions of more than 3000 dpi. Today, the filmscanners work with resolutions of 4000 dpi and more - in former times, those margins could only be handled by the huge drum scanners.

Consider the scanner to be adopted before determining the module size to be used. Scanning an A4 at 300 dpi on fast mode takes about 12 seconds. Scanning a 35mm negative at 4800 dpi takes approximately 65 seconds.
