What is the DPI of an Image? In this modern world, there are many people who would like to click pictures or take selfies from their smartphone or DSLR camera. Most people prefer to capture images and get them printed for decoration purposes.
There are many companies who like to print a large banner and use it for promotional purposes. For printing large posters, it is really important that your image must have high DPI so that printing can be done in the most efficient manner. DPI is Dots per inch defines the clarity of the print. There are many ways to increase the DPI of the image.
What Is DPI?
DPI stands for “dots-per-inch,” and is a specification for printing and for setting the print resolution of an image.
A print is made from millions of tiny dots of ink. The DPI setting determines how many dots the printer drops onto every square inch of the image. You need to understand how DPI works because it controls the two most important things in printing:
- The quality of your print. In simple terms, a higher DPI means a higher quality print. Most good home printers can output at 300 dpi, and professional printers much higher.
- The size of your print. A pixel in a digital image is the equivalent to a dot in a print. So, if you print an 1800 pixel wide image at 300 dots-per-inch, the printed image will be six inches wide. Print the same image at 180 dpi and it will be 10 inches wide.
How DPI Affects Your Prints
Here’s an image to illustrate. Below are two lines that consist of the same 40 squares—the same size and same color. The squares are less tightly packed on the top line, equating to a lower DPI; and more tightly packed on the bottom line for a higher DPI.
The effect is clear. On the Lower DPI line the gradient is a lot less smooth. You can see clear edges against each of the squares. The line is also a lot longer.
On the Higher DPI line the gradient is much smoother. It’s almost seamless. The line is also a lot shorter.
This demonstrates the balancing act you often need to make when setting the print resolution: size versus quality. If you’re working with low res images then you’ll have to make a trade-off between the two.
Where possible, you should always save your work in as high a resolution as you can. Because Resizing your image to make it larger won’t improve the print quality.
What DPI Should You Use?
All this begs the question: What is the best DPI to print at? The standard rule is that you should aim for 300 dpi. This is great quality for photographs, and it’s questionable how much extra detail the human eye can even discern beyond that level.
But if your image is too small to print at 300 dpi, don’t worry. The intended viewing distance of the print plays a large role in what resolution you need. For images you’ll hold in your hands, like photos, leaflets, or magazines, 300 dpi or higher is the target, but 250 will do at a push.
With posters or pictures, you’re going to frame, you can get away with a lower resolution because you’ll mostly be looking at them from a few feet away. 200 dpi should be okay, or even a little lower. This also applies when you’re printing on different materials, like canvas.
And so on. The further away you intend to look at your image, the lower you can set the resolution. A billboard poster designed to be seen from across the street might be printed at as low as 20 dots per inch.
