Pasteup refers to the process of creating a layout or design using images, graphics, and text. The concept of pasteup is opposite to the idea of digital design, where everything is created and edited on a computer. Instead of pasteup, the antonyms could be digital design, digital layout, digital art, or digital composition. These expressions describe designs made entirely on a computer, rather than by physical manipulation of images and text. Other antonyms for pasteup might include formatting, layout, composition, editing, or publishing. Whether digital or traditional, the goal of all these methods is to create visually appealing and effective designs that showcase the designer's skill and creativity.
