If you are using a printing press it is important that you have it properly aligned before printing your material. If your press is not properly aligned you will end up applying an uneven force to the object you are trying to print on. This will allow for your art to turn out fuzzy and obviously not looking even or straight on the surface you were printing. Plus, uneven alignment of a printing press can do damage to the press in the long run. It is best to keep your printing press aligned to avoid these potential problems.
