Regarding graphic design and images, a common feature of grunge bands was the use of "lo-fi" (low fidelity) and deliberately unconventional album covers, for example presenting intentionally murky or miscolored photography, collage or distressed lettering. Early grunge "lbum covers and concert flyers appeared Xeroxed not in allegiance to some DIY aesthetic" but because of "economic necessity", as "bands had so little money". This was already a common feature of punk rock design, but could be extended in the grunge period due to the increasing use of Macintosh computers for desktop publishing and digital image processing. The style was sometimes called 'grunge typography' when used outside music. A famous example of 'grunge'-style experimental design was "Ray Gun" magazine, art directed by David Carson.
