Printing is the process of producing text and images with ink on paper using a printing press. Printing jobs can be done using a printing press or printer which is available in various types and uses.
There are inkjets which are printing machines that use ink to print. It is mainly used for home or small office printing. The ink is fired through a jet which gives it the name inkjet printer. They can also be used for large businesses or for people in the printing business. Laser printing is another type commonly used for large business and commercial purposes. This type uses a laser and toner. The laser is used to scan the image and communicates with the toner which uses the toner to help create the image.
Offset printing is basically meant for commercial use. It spreads the ink on a metal plate with an etched image which is then transferred to a direct surface known as a rubber blanket. This is finally transmitted to the paper by pressing it against a direct surface. This leads to lower printing costs, better quality, and printing in bulk. Flexography printing machines are used for packaging materials and use plastic or rubber plates fed to the belt. This then goes to the impression cylinder which creates the image impression.
Flexography has versatility when it comes to what can be printed. Screen printing machines are popular with textiles and clothing. It creates a screen from a fabric usually silk, nylon or polyester. The stencil on the screen is stretched on the material with the image cut into it. Electrostatic printing presses are used to print large world maps and use paper that is coated with a layer of zinc oxide. This paper is filled with images and flows through a literal ink bath where the true ink is attracted to the paper.
