What is DPI in printing?

A group of dots/pixels creates an image we see physically printed substrate or through electronic media. DPI stands for the printing quality of the image and text content from the substrate designer’s or printmaker’s perspective. It is an international metric on behalf of recognizing print quality before printing. Higher dpi means better quality printing results and lower DPI count prints worse quality. DPI refers density of dots (Total Number of DOTS PER SQUARE INCH).

The standard benchmark of DPI

→ 300 DPI Images for Printing

→ 72 DPI for Web Pages

Let’s understand what is DPI in printing in details

While we are planning to buy a Digital Printer or planning to print a design on any stuff we must check the image quality used if printing a file printing that can engage our audience.

The relation between Image Print Size and Printing Machine Head has close relationship.

→ The metric of any Inkjet Digital Printer’s print quality is based on the print head having a maximum number of nozzle per inch, standard 300 DPI but EPSON high-quality digital printing has many inkjet printer series that can able to print on paper & fabric 600 DPI, 1440 DPI, and 2880 DPI

There are 2 terms in respect of image quality

  1. PPI (pixel per Inch)
  2. DPI (dot per inch)

Both terms go for the same purpose, Mostly we measure any electronic image in pixel size. for example, there is a picture having a size of in inch

2″x3″ How many pixels it should have for high-quality (300 DPI) printing image

Pixel might be 2*300×3*300=600 pixel x900 pixel while creating image foil for printing.

DPI on the print object?

300 DPI is the benchmark for high-quality print printing on paper and any other types of materials and 72 DPI benchmark for any file quality on electronic views.

A group of pixels made images, a higher number of pixels create a rich look and lower pixels lead to pixilated visually. The printing quality of any object is related to image quality and printer quality that can produce print quality.

Difference Between DPI and Pixels Per Inch

Both the terms are considered for quality perspective here we understand for the best quality printing.

300 DPI =1″x1″ square inch

300 Pixel=1″x1″

Suppose that there is a picture size 5″ Height x 6″ Wide, to create a best quality image for printing required total pixel size

5*300=1500 pixel

6*300=1800 pixel

Creating image required pixel size 1500×1800=27,00000 total pixel

1 Mega Pixel=1,00,000 pixel

=2700000/100000=2.7 Mega Pixel

If you want to make a high quality photo, go for camera quality at least 2.7 mega pixel that will produce best quality photo print. Produced image will have 300 DOT count per inch.


I (Suresh Kumar) have over 24 years of experience designing, printing, advertising, and printing technology space. During this period I have worked with lots of trusted printing machine brands. Experienced a variety of ink, print media, and post-press equipment .brand. I am fond of grabbing high technology and fast printing equipment even traditional and digital printing machines. Our continuous practice in offline print shops, online printing stores, the latest printing technologies, and learning curiosity made my in-depth knowledge of the printing industry.
