With Photoshop open, go to File > Open and select an image. 2. Go to Image > Image Size. 3. An Image Size dialog box will appear like the one pictured below. 4. Enter new pixel dimensions, document size, or resolution. The original image is at 300ppi. + if you are scanning film to edit and print, output size should match the print size you are printing with the dpi of the printer you are going to use. for example, our Lambda printers print at 200 dpi, scanning at a higher dpi is not necessary. + if you are scanning and cropping the image, consider scanning at a higher output size resolution: 600 dpi. Printing resolution: 300 dpi. Setting the Resolution in ScanGear (Scanner Driver) In ScanGear, you can specify the resolution with Output Resolution in Output Settings on the Advanced Mode tab. Example of Appropriate Resolution when Printing to Scale. The scanning resolution is automatically set so that the value set in DPI to PPI is, for the most part, 1:1. Difference between PPI and DPI is mainly the type of media they pertain to. The PPI determines the print size because you have a limited amount of pixels on your image – so a greater pixel density means that the print will have enough details and sharpness.
