What is the significance of image DPI (dots per inch) in ensuring high-quality print output?

The significance of image DPI (dots per inch) in ensuring high-quality print output is that a higher DPI results in a greater level of detail and sharpness in the printed image. This is because a higher DPI means there are more dots of ink per inch, which allows for a more accurate representation of the original image. Therefore, a higher DPI is essential for achieving crisp and clear prints with fine details.
