DPI (Dots Per Inch)

DPI, or Dots Per Inch, is a measure of resolution for printed images. It describes how many individual ink dots a printer places within one linear inch of output. The higher the DPI, the finer the detail and the sharper the print. For professional print output, a resolution of 300 DPI at the final output size is the standard minimum. Images used at lower resolutions appear pixelated, blurry, or soft when printed. DPI is relevant to logo design primarily in the context of raster images — photographs, raster-based textures, or PNG/JPEG logo files. Vector logos, being mathematically defined rather than composed of pixels, are resolution-independent and can be output at any DPI without quality loss. This is one of the primary reasons why professional logos are always designed and delivered as vector files. When raster versions of logos are needed for specific print applications, they should be generated at the correct DPI for the intended output size.
