When it comes to printing, “set off” refers to the transfer of ink from the print plate to the blanket and then to the paper. This is a crucial step in the printing process, and it’s one that requires careful attention and a skilled hand.
The first thing that must be done is to “set” the image on the plate. This is done by using a light-sensitive coating, which is exposed to light in order to harden the image onto the plate. Once the image is set, the next step is to “off” the excess ink. This is done by using a damp cloth or sponge to remove the ink that isn’t part of the image.
The purpose of set off is to ensure that the print job turns out exactly as intended, with clean, sharp edges and no bleed-through. This method is often used for prints that require a very high degree of accuracy, such as business cards, labels, and other marketing materials.
After the ink is removed, the next step is to “set” the image on the paper. This is done by using a printing press, which transfers the ink from the plate to the paper. The final step is to “off” the excess ink from the paper. This is done by using a damp cloth or sponge to remove the ink that isn’t part of the image.
Set off is an important printing technique because it allows for a more efficient use of space on a page. When text is set off, it is indented from the left margin, which creates a white space on the page. This white space makes the page appear less cluttered and makes the text easier to read. Additionally, set off can be used to highlight important information or to create a visual break between sections of text.
