👉 DPI, or Dots Per Inch, is a measurement used to quantify the resolution of printed text and images. It represents the number of discrete dots of ink or light that are packed into a given area, typically measured in points per inch. In engineering, DPI is crucial for optimizing print quality, ensuring that text and graphics appear sharp and clear. Higher DPI values result in finer details and smoother gradients, making them ideal for high-resolution printing applications such as professional publishing, graphic design, and digital signage. Conversely, lower DPI values are suitable for lower-resolution printing needs where file size and print speed are prioritized. Engineers often balance DPI settings to achieve the desired visual quality while considering factors like printing medium, intended use, and file size constraints.
