Photography Terms - The Difference Between DPI and PPI

DPI PPI and PPI are two essential terms used in graphic design photography, digital imaging, and. However, there are some who are unable to comprehend the distinction of DPI and PPI and are able to use the terms interchangeably. This can cause confusion and even costly delays on a crucial project. The reason is that even though the two terms are related, they’re different methods of determining what resolution an image has.

What is DPI?

Dots Per Inch, also known as DPI, is a printing term that is frequently used in conjunction with how the resolution is displayed by printers as well as different output equipment. DPI measures the number of dots that are projected or printed per inch of the medium involved. In the instance of an inkjet printer (also known as a laser printer), every image is comprised of a number of tiny dots of pigment, each with a variety of hues and colors.

Numerous color printers print high-quality images at 780 DPI or higher, but many experts believe that in the majority of cases, 1440 DPI is enough to get excellent quality photo printing, and in most cases, increasing it will only lead to using more ink, but not increase image quality. Print.

What is PPI?

PPI, also known as Pixels Per Inch, is a term used to describe the resolution of a digital image. It’s an indicator of the number of pixels within an inch of the image. Images of higher quality have higher PPI, and generally, good high-quality images and images range from 300 to 360 Pixels per Inch or higher. Web images with low resolution typically have around 72 PPI; however, good quality images maybe even more.

In addition to being a measure of the high quality of a picture, PPI also determines the size of the image’s output also. Changes in the image’s PPI will alter the quality of that image. For instance, if you reduce an image with a 300 PPI down to 150 PPI, it will increase the size of the output image but decrease its quality. Increasing the PPI to 600 will reduce the size of the image and improve your image’s quality.

Put together PPI together with DPI together.

Now that the distinction between DPI and PPI is now clear, Here’s an illustration that shows the way PPI and DPI are in sync:

Take an image of 3600 pixels by 3600 and has 360 PPI as the resolution and print with 1440 DPI. The printer uses four dots of ink vertically and vertically to print each pixel. This will result in an image of 10-inches by 10 inches.

If you boost the resolution of this image by 720 pixels, it will improve your image’s quality. Picture and the printer will produce an image that measures five inches wide by five inches, and each pixel is printed using the use of two ink dots vertically and vertically.

If you lower the image’s PPI down to 180 PPI, the final image will be 20 by 20 inches, every pixel being comprised of eight ink dots, horizontally and vertically. This results in a more prominent image but less image quality.

A Quick Review

In essence, the distinction in between DPI the difference between DPI and PPI refers to the fact that DPI means the resolution of an image as it is printed or displayed, and PPI pertains to the resolution of the source or input of the image. This knowledge can help save time, effort, and money and also the confusion that could be caused by confusing both terms.
