The main distinction between DPI and PPI is that the DPI is a physical ink-dot to be printed on paper, while the PPI is the number of square pixels in one inch of the image shown on a computer display. DPI reflects the characteristics of a physical printer, and PPI is the characteristics of a digital image.
How much DPI do I need to print a picture?
When printing images, different resolutions are used. Good results for printing yields 300 DPI, but it is better to apply 600 DPI. The DPI for the image to be printed is largely dependent on the printer (or plotter) on which it is printed.
How do I change the DPI of an image?
You can change the number to be 300 dpi or whatever you want it to say. To change it, UNCHECK the Resample Image box in the Adobe Image - Image Size box (so that it will not resample the pixels), and then when changing the Dpi number, the pixel count will not change (just the printed size in inches or mm will change).
What does DPI mean in photography?
Abbreviation DPI stands for “dots per inch”, and is related to the quality of your photo. In general, the higher the DPI of an image, the higher its quality. This is due to the fact that the resolution of the image is higher, and therefore the image has more details.
What is the difference between DPI and PPI in printing?
(Folk who use the metric system will prefer points and dots per centimeter.) The dpi term should be limited to print output on a laser printer or ink-jet printer; ppi is typically reserved to the dimensions of an image as it’s stored in a file or view on a screen.
