In simple terms, litho printing involves transferring ink from a printing plate to a rubber blanket before it is finally printed onto the desired material, usually paper or cardstock The process gets its name from the fact that the ink is not directly applied to the printing surface but is offset onto the blanket first.
The litho printing process typically involves the following steps:
1 Prepress: This stage involves preparing the artwork for printing The design is transferred onto printing plates, usually made of aluminum, using photosensitive chemicals These plates are then mounted onto the printing press.
2 Printing: The printing press consists of a series of rollers that transfer the ink from the plate onto a rubber blanket The blanket then transfers the image onto the paper as it passes through the press The process can be repeated for different colors, as each color has its own plate.
3 Finishing: Once the printing is complete, the paper may go through additional processes such as cutting, folding, or binding, depending on the final product requirements.

Additionally, litho printing is compatible with a wide range of paper types and sizes, giving designers the flexibility to experiment with different materials.
