![]() The higher the DPI, the better quality print. PPI=Pixels per square inch (same thing as DPI, just a different name) The human eye can see a lot more than 96 dpi! Studies indicate that we can see detail as much as 9,600 DPI (coincidence that it starts with 96). ![]() Many people don't accept that.Īs for file size, that will depend on the file format (GIF, JPG, PNG, etc) other binary format if it is a printable document (Word doc, PDF, bitmap, etc) Eventually you come to nderstand that what you need as an image file is determined by what you intend to do with it (display or print). What is the image's "DPI"? That is determined at print time, by your computer setup (software settngs, printer driver, printer settings, etc).Ħ00dpi means 600 dots (like pixels) per INCH, so it must be referring to printouts. "640x480 resolution" means 600 pixels wide, and 480 pixels high, ON THE SCREEN. So DPI has no importance for displayed images, only printed images. Simplest way I explain it is that INCHES only come into play when you are printing. Something to consider if you try to do math like if you have 800圆00 on a 15 inch monitor. Just to clarify, a "15 inch monitor" is roughly 15 inches on the diagonal (not across), and most monitors don't fill the entire area with image.
