DPI refers to the resolution of an image for what specific context?

1. Digital screens

2. Image editing

3. Printing

4. Graphic design

The correct answer is: Printing

DPI, or dots per inch, specifically refers to the resolution of an image in the context of printing. When preparing images for print, DPI is a critical factor that determines the quality and detail of the printed output. A higher DPI value indicates that more dots of ink are used per inch, leading to finer detail and higher resolution in the printed image. This is particularly important for ensuring that images look sharp and clear when printed, especially at larger sizes. In contrast, while visual display resolution on digital screens is often discussed in pixels per inch (PPI), it is distinct from DPI. Image editing and graphic design involve various processes that may include DPI considerations, but the term itself is usually used to address how an image will be rendered in printed format. Understanding DPI helps photographers and graphic designers ensure that their work maintains high quality when moving from a digital to a physical medium.
