PNG images: Assorted Clipart Collection
The term "clipart" originated through the practice of physically cutting images from pre-existing printed works for use in other publishing projects. Before the advent of computers in desktop publishing, clip art was used through a process called paste up. Many clip art images of this era qualified as line art. In this process, the clip art images are cut out by hand, then attached via adhesives to a board representing a scale size of the finished, printed work. After the addition of text and art created through phototypesetting, the finished, camera-ready pages are called mechanicals. Since the 1990s, nearly all publishers have replaced the paste up process with desktop publishing.
