Resolution for picture sizes dpi
A printer that has a resolution or DPI rating of 2400 can place 2400 individual dots of color within a one inch span on the page. What does 2400 dpi mean?ĭPI or “dots per inch” is a term that normally describes the resolution of a printer since printers produce colors by placing colored dots on a piece of paper. So a 10mm image is 118 px square at 300 dpi making 109 kb multiplying that by 10, the 100mm image is 1181 px square. If you scan a 2×3-inch photo at 1200 dpi, for example, it will become a 16×24-inch digital image without losing quality. If the original photo is small, scan at 600 dpi or higher. If you’ll want to more than double the size of the original photo, go even higher with the dpi. For example, 1200 X 1200 dpi will give you better resolution or copy/print quality than 600 X 600 dpi, thus giving you better copy/print quality and better half tones. Is 600 dpi or 1200 dpi better?īigger and Better Resolution The higher the dpi the better the resolution and the better copy/print quality. If the text is going to be reprinted, a DPI setting of 600 or better is ideal. The lowest DPI that is needed for the scanned text to display and print properly is 300 DPI.
