Offset printing

Offset printing is like making copies of a drawing or a picture. But instead of using a regular copy machine, we use a big printer that can print on lots of paper sheets very quickly.

Now, imagine you have a picture you want to print a thousand times. Before we start printing, we need to make a "master copy" of the picture. So, we take the original picture and use a special machine to transfer the image onto a metal plate. This plate has tiny bumps and grooves on it that can pick up ink.

Next, we put the plate onto the big printer and load a bunch of blank sheets of paper into it. When we turn on the printer, it rolls over the plate and picks up ink using the tiny bumps and grooves. Then, it rolls over the paper and presses the ink onto the paper to create a copy of the picture.

We repeat this process over and over again until we've printed as many copies as we need. Offset printing is used a lot for printing books, brochures, flyers, and posters because it's fast and produces high-quality prints.
