Offset printing is the most commonly adopted printing method that is used commercially almost all over the world since the 20th century. Offset printing is also referred to as offset lithography; this method is used to create a vast number of printing materials that are mostly utilized by businesses and companies of almost all kinds.
How to offset printing works
The procedure of offset lithography is quite simple; it’s all done under one principle “do not dissolve water and ink together.” The design you want to get printed is kept on a thin metal slate. The plate or slate is dampened with water and ink with the help of rollers on a specific press. Special oil-based ink is spread over the design, the water, and the empty area.
The area that is inked is then headed towards the rubber cylinder also called blanket, and then it straightaway goes to the paper. This procedure is called offset because the design does not reach from the plates to the paper and it transferred to the paper after undergoing through another surface.
Why offset printing is called 4-colored printing?
The offset printing process and the digital inkjet printer use the four types of inks only named, cyan, magenta, yellow, and black. This color sequence is also referred as CMYK. The inkjet printer uses the four colors at the same time to develop the image on the paper whereas when it comes to offsetting printing, all the four colors are used separately. Each color is applied to different plates. The spots of the four colors are displayed on the material separately but beautifully, and it seems like all the colors are merged. It makes our eyes believe that we are watching a full view of different colors in the same design. Due to the use of 4 primary colors by the printer, this printing method is also named as the four color printing process.
