What does the term "bleed" refer to in printing?

The term "bleed" refers to the area of an image that extends beyond the trim edge. In printing, this is a crucial concept because it ensures that when the printed material is trimmed to the final size, there will be no unprinted edges that show, which can detract from the overall appearance of the printed product. By allowing colors, images, or backgrounds to extend beyond the intended final dimensions, printers can account for slight misalignments and variations during the cutting process. This practice maintains a professional look by ensuring the design flows seamlessly right to the edge of the paper.

In contrast, the other options address different aspects of printing or graphic design that do not relate to the concept of bleed. For instance, color intensity refers to how vivid or saturated an image appears; texture relates to the surface feel or visual representation of printed materials; and image resolution pertains to the detail and clarity of an image, usually quantified in dots per inch (DPI). Each of these is important in its own right but does not capture the specific meaning of "bleed" in the context of printing.
