What is Printing?
What is printing?
It means reproducing words or images on paper, card, plastic, fabric, or another material. It can involve anything from making a single reproduction of a priceless painting to running off millions of copies of the latest Harry Potter. Why is it called printing? The word ultimately comes a Latin word, premĕre, which means to press; just about every type of it involves pressing one thing against another.
The three most common methods are called relief (or letterpress), gravure (or intaglio), and offset. All three involve transferring ink from a printing plate to whatever is being printed, but each one works in a slightly different way. First, we’ll compare the three methods with a quick overview and then we’ll look at each one in much more detail.
- Relief is the most familiar kind . If you’ve ever made a potato print or used an old-fashioned typewriter, you’ve used relief . The basic idea is that you make it reversed. Sticking-up (relief) version of whatever you want to print on the surface of the printing plate and simply cover it with ink.
- Gravure is the exact opposite of relief. Instead of making a raised area on the plate, . When you want to print from the plate, you coat it with ink so the ink fills up the places you’ve dug out.
- Offset printing also transfers ink from a printing plate onto paper. But instead of the plate pressing directly against the paper, there is an extra step involved.
