Difference Between DPI and PPI Design and Printing
There is often confusion over the term of the images and print resolution. You can often see the DPI and PPI was exchanged and was wondering what is the measurement of DPI and PPI difference.
Technically convert both counts. 300dpi = 300ppi, 72dpi = 72ppi, and more. The term itself means different things.PPI or “Pixels Per Inch”: refers to the digital device, usually a computer and display monitor, screen smartphone, image scanner, digital camera, etc. The PPI is the number of pixels per square inch in your image. PPI affects image size and print quality. If there are too few pixels per inch, the pixel will be larger creating more jagged-edged appearance. The more pixels per inch pixel becomes smaller and sharper and better images will look.DPI or “Dots Per Inch”: Specifies printing and the number of individual points scored in a span of 1 inch.
A printer with a maximum of 720 dpi can print up to 720 dots of ink per inch. A printer with a maximum of 1200 dpi can print up to 1200 dots of ink per inch. With just think you can see how the final printing quality is affected. A printed image in 300dpi compared to one printed 72dpi be sharper, clearer, better to have color, and better overall picture. Printed in low resolution images will look blurry and low quality. The higher the DPI the better. The printer can only print resolution of printed images. If the image 72ppi maximum dpi printer can print images are 72dpi. A picture can not be printed at 72ppi 300DPI.DPI = Output Resolution / Print Resolution ResolutionPPI = Input / ResolutionComputer screen images are generally optimized for viewing pictures of 72ppi. That is why the picture looks crisp 72ppi internet on a computer monitor, but printed poorly.
The We Know Home: Images with higher PPI printed in large DPI will look better than pictures with low PPI printed on low DPI Fig. printed on a small document that can be viewed up close such as brochures, posters, letterhead, business cards should be printed on high DPI, usually 300 dpi or higher. Images are printed on signs bigger is not often seen close up like billboards or banners may be printed in the lower DPI as 72dpi. From a distance our eyes can not distinguish the low quality of larger print signs.
