What is PPI?
PPI stands for “pixels per inch,” and it refers to the resolution of an image or display. PPI is a measure of the number of pixels that are contained within a one-inch square of an image or display. The higher the PPI, the more pixels are contained within a one-inch square, and the higher the resolution of the image or display.
In printing, PPI is an important consideration because it determines the sharpness and clarity of the printed image. Higher PPI values result in higher-resolution images, which are typically sharper and more detailed. Lower PPI values result in lower-resolution images, which may appear pixelated or blurry when printed.
To ensure that an image is of sufficient resolution for printing, it is important to check the PPI of the image before sending it to the printer. Most printers recommend a minimum PPI of 300 for high-quality printing, although this may vary depending on the specific printing process and the size of the printed image.
By understanding the concept of PPI and how it affects the resolution of printed images, you can ensure that your printed materials are of the highest quality.
