102 DPI JPEG 300–600 K Web site About 400–600 pixels wide for a large image; 100–200 for a thumbnail image 72 DPI JPEG 20–200 K Printed in a book or art magazine Multiply intended print size by resolution; e.g. an image to be printed as 6” W x 4” H would be 1800 x 1200 pixels. 300 DPI EPS or TIFF 6–10 MB Printed on a laserwriter As explained in the article, DPI refers to the mouse’s sensitivity. The higher the DPI, the more sensitive the mouse is. Hence, a 1200 DPI mouse is twice as sensitive as a 600 DPI mouse. The DPI setting you use will depend on the type of game you are playing. FPS gamers would prefer a mouse with 600 DPI to an extremely sensitive mouse. 2. Select “Image” from the top menu bar and then select “Image Size” from the drop-down menu. 3. In the Image Size window, make sure that “Resample Image” is checked and set the 300dpi is good for sharing photos with family and friends. It also takes up less space and is easier to share cause the file size is smaller. If you scan a 4x6 at 300dpi you can make a enlargement no bigger than a 5x7. 600dpi you get more resolution, so the image will not pixelate The ideal pixel density (PPI) depends on the output format, output device, the intended use and artistic choice. For inkjet printers measured in dots per inch it is generally good practice to use half or less than the DPI to determine the PPI. For example, an image intended for a printer capable of 600 dpi could be created at 300 ppi. Interesting. The review of the Plustek 7600 at Filmscanner.info gave a measured resolution of 3250 dpi when scanning at an indicated 7200 dpi and 2600 dpi when scanning at an indicated 3600 dpi. And that's of a high contrast lab grade original. Expect less, particularly off-center for a typical cardboard mounted slide. For laser (so toner) presses, 1200 dpi printers will consume less: they pile fewer toner particles on top of each other, and they allow for a higher lineature in the AM screen. The latter allows for white space to fill up faster, helping to reach higher densities with less toner. For inkjet presses, the story is more complicated. KGSw.
