Explanation

Planographic printing involves the process of printing from a flat surface. Lithography and offset printing are the process that involves planographic printing. It uses the concept of not mixing water with oil. Lithography is carried out using a stone or a metal plate. Originally, it used oil or fat. The word ”lithography” also refers to photo lithography. In the offset printing, the inked image is moved from a plate onto a rubber blanket and then back to the printing surface. Most of the modern day printing is done with the help of the offset printing process.
