PPI and DPI are two critical concepts that should be understood to anyone working with pictures. Both of the terms effectively and efficiently reflect and define the clarity and resolution of an image. Nevertheless, people often use them interchangeably which is not acceptable at all. Also, many people are confused about choosing between dpi vs PPI for their projects. It is mandatory that you understand how each of them works and how to apply it in your project in order to produce optimized quality digital images and thus save your valuable time, effort and money. Lots of people don’t know the difference between dpi and PPI. In this article, you will get to know how to use both of them efficiently.
First, you need to know what is PPI and DPI respectively!
What is PPI?
PPI stands for pixels per inch and refers to density as well as the fixed numbers of pixels that a screen displays. When you zoom the image, you will witness the breakup of pixels into colored squares.
Furthermore, there are sub-pixels within pixels in the red, blue and green color which you cannot see as color processing efficiently blends them in a single hue. That is the reason PPI employs the RGB color model. It is used in digital photography, computer monitors and television screens.
Usage Of PPI
You use PPI when you work with digital images. Undoubtedly, an image with high PPI tends to have great quality and high pixel density. 300 PPI is considered as industry-standard quality. Also, keep in mind that increasing the PPI will increase the size of your file. Furthermore, a 72 PPI and a 3000 PPI image appear the same on your screens.
What is DPI?
Many people don’t know the meaning of DPI. It stands for dots per inch and refers to printer resolution level. Printers reproduce an image by spitting out small dots, and the number of dots per inch affects the quantity of detail and the overall print quality.
DPI uses the color model CMYK (cyan, magenta, yellow and key/black) to control the amount of red, green, and blue light that is reflected in the white paper. This is also known as the pattern of subtractive colors.
Usage Of DPI
You use DPI when your design needs to be printed physically. Keep in mind that each model, make and style of the printer has its own DPI settings. There is no set standard shape or dot size so higher DPI is not always the same as higher print quality. At 1200 DPI the dots of one manufacturer might look as good as the dots of another manufacturer do at 700 DPI.
What is the difference between dpi and PPI?
DPI tells about the amount of ink dots used on a printed image whereas PPI explains the resolution of pixels of a digital image. PPI is vastly used for screen display but also has the power to affect your design and the final result. On the other hand, DPI has no concern with digital and print.
No doubt PPI will empower you to get high-resolution images. And knowing how to navigate DPI will assist you to efficiently communicate with printing machines and professionals inside the printing industry. Unless you are a printer, your major focus might be on PPI. But it is crucial to apprehend the procedure of bodily printing in case your work requires it on an everyday basis.
In the end, even the fine design may be ruined by way of a poor photograph resolution. That’s why if you need crystal clear first-class in your designs, ensure you’re working with a professional designer.
