What Is DPI & What Does Dots Per Inch Stand For?

PPI vs. DPI: what's the difference?

Dots Per Inch (DPI) is an abbreviation for dots per inch. It’s a phrase used to describe resolution, print quality, and picture quality.

In basic terms, a certain number of dots will be produced for every inch square of print. The higher the number of dots, the better the print quality (there are some exceptions).

In this blog, we’ll answer some frequently asked concerns concerning DPI and provide advice on how to acquire the greatest DPI when printing flyers or business cards.

What Does DPI Mean When It Comes To Printing?

When it comes to printing, the phrase 300dpi is frequently used. So, what does 300dpi mean? While you may theoretically print at any DPI, 300dpi is the recommended print resolution for a flyer or poster that will be viewed from a distance. Printing equipment generally has the power to print at over 1000dpi, but the advantage is modest if you get over 300dpi, and you’ll struggle to see a discernible change in the quality of your prints. Designing your print at 300dpi reduces file size, allowing us to load, set up, and transmit your files to print in less time.

If your print is intended to be viewed from afar, such as a banner on the side of a building, you can design it at 72dpi (25 percent of 300dpi). This is a printer’s technique because occasionally enormous banners with a file size of meters in length at 300dpi are too large to open in Adobe Illustrator. Reducing the print DPI to 72 (or 25%) reduces the file size by 25% while having no effect on the quality of your big format prints, which will be read at a distance anyhow.

What Is DPI (Dots Per Inch) Resolution?

When we talk about DPI resolution, we’re talking about a measurement of the amount of dots per inch, not merely an abbreviation for dots per inch. Simply put, the printing resolution of 300dpi refers to the number of dots per inch, or 300 dots per inch.

DPI stands for Dots Per Inch, and it refers to the number of dots generated by the printer (dot density). Resolution can also be utilized in other situations, such as the pixel resolution of your display. You may be familiar with the phrase Full HD, which refers to a pixel resolution of 1920×1080, which is a measurement of the number of pixels in height and breadth on your display.

We realize it’s confusing, but the DPI resolution in print always refers to the number of dots per inch.

As a general rule, raising your DPI will not improve the quality of your image. If you have an outdated image that is just 64 pixels by 120 pixels, for example, it will appear blocky. Setting this image to 300dpi won’t miraculously add details that weren’t there before; it simply means that the blocks will have 300 dots per square inch when printed.

DPI vs. PPI: What’s the Difference?

What is the difference between DPI and PPI resolution, we are frequently asked. This is a bit easier to answer because it simply relates to the difference between a physical and a digital resolution. DPI (dots per inch) is a measurement of the number of dots per inch generated by a physical printer in a given square inch, whereas PPI (pixels per inch) is a measurement of the number of pixels per inch square on a screen.

It’s best not to have these two terms mixed up; for example, you may have a DPI of 300 but a PPI of 90. Your prints may appear blockier on screen but smoother when printed in this case. To get as near to the DPI as feasible, it’s recommended practice to design on high-resolution displays.

PPI is a tough concept to grasp since you can have two displays with the same resolution of 1920×1080 pixels, but because PPI is a measurement of the amount of pixels per square inch, if one monitor is 24″ and the other is 40″, the PPIs will be 90 and 55, respectively. Essentially, the number of pixels on the screen is the same, but because one monitor is larger, the pixels are larger, and therefore there are less pixels in an inch square. This is not the case with DPI, since if you design to 300DPI, the printer will know to convert your file to 300 dots per inch of print, regardless of the pixel resolution. As we’ve already stated, this will not add any additional information that isn’t already present.

What Is The Difference Between Pixels And DPI (Dots Per Inch)?

To begin, pixels are digital and are only ever displayed on a monitor as a perfect square grid. Imagine a Greek mosaic; each square tile is a pixel, and the more pixels you have, the easier it is to add detail to a picture. DPI, or dots per inch, are microscopically small polka dots with space between them. They are less exact but appear softer and smoother.

Pixels are made up of RGB colors; if you’re not sure what RGB stands for, check out this blog post. In essence, each pixel may be a blend of red, green, and blue to appear as any color you desire.

Each individual dot can only be Cyan, Magenta, Yellow, or Black when there are dots per inch (CMYK). To form the color, all four colors are layered over each other in a mesh-like pattern of varying quantities on a tiny layer.

What DPI Is a High Resolution Image?

As a result, there are no print standards like there are for computer monitors or televisions. Industry-standard HD or 4K tags are not available on print machines. We are frequently asked what the normal dpi for printing is, therefore we try to provide an answer that is consistent across most printers.

In the printing business, 300dpi is regarded high resolution enough to produce great-looking prints from a distance of a few meters, while 72dpi is considered high resolution enough to produce great-looking prints from a distance of a few meters. So, if you’re wondering what is an acceptable DPI, the lowest is 72 and the highest is 300, since anything more is overkill.

Business cards, flyers, and tags should all be 300dpi, whereas posters and banners should be 72dpi.
