👉 DPI, or Dots Per Inch, is a unit of measurement used to quantify the resolution of printed text and images. It represents the number of dots, which are tiny points of light or ink, that a printer can place in a linear inch of print. A higher DPI value means more dots per inch, resulting in finer detail and sharper images, which is crucial for high-quality printing, especially in professional settings like graphic design or publishing. Conversely, a lower DPI value produces coarser prints, often seen in lower-quality or smaller print formats. The relationship between DPI and perceived image quality is such that while higher DPI values generally enhance clarity, they also increase file size and may not always lead to noticeable improvements in print quality beyond a certain point, typically around 300 DPI for standard printing tasks.
