To avoid the inherent limitations of the printing devices that we use (whether it be a press, digital press, copier, or printer), we need to print our jobs that extend to the edge of the page on a larger than necessary piece of paper and then trim the paper after the fact to produce the desired result. Now, I’m well aware that there are some desktop printer models on the market that allow you to print all the way to the edge of the paper, but by and large, you won’t come across these models very often. If you’ve ever designed a product with elements extending to the edge of the paper, you’ll know that when you print your project to a desktop printer, you end up with a white margin around the page because the desktop printer is incapable of printing to the edge of the paper. Even modern digital presses, as well as desktop printers, have this limitation. The same would happen if you printed to the edge of a piece of paper on a printing press: The ink would build up on the edge producing globs of ink on the paper. However, the end result would be similar to applying masking tape to the corner of a room before you paint: Often, the paint creeps under the masking tape, creating an undesirable look. A printing press is incapable of printing ink to the edge of a piece of paper. Why would you need to include bleed in your InDesign project? Let’s start with the fundamental problem. This is required solely because the physical printing process as a whole is not perfect and has inherent limitations. Bleed refers to a printing solution where elements on a page are designed to extend past the edge of a piece of paper. It is neither needed nor desired for output to any format other than print. What is Bleed?īleed is a term that comes into play only when you’re designing content intended for print output.
So when you mention the term bleed, it’s not uncommon to receive a glazed stare looking back at you. With all of these modern digital formats, we sometimes forget that InDesign is still used heavily for print output. InDesign is now a product that can produce content for many different output formats, including PDF, EPUB, HTML, XML, and even mobile apps. InDesign is a product that has evolved considerably since its inception more than two decades ago. We all had to start somewhere, so why not start right here?
