What does the process of offset lithography utilize to transfer images onto paper?

The correct answer involves the use of water rollers and grease-based inks in offset lithography. This printing process relies on the principle of repelling water and attracting ink. The print plate is treated so that the image area is oleophilic (ink-attracting) while the non-image area is hydrophilic (water-attracting). During the printing process, water is applied to the plate to keep the non-image areas damp and prevent ink from adhering to these parts. The grease-based ink is then applied, which only adheres to the image areas of the plate. This combination of water for the non-image areas and grease for the image areas allows for precise and clean printing on paper.

Offset lithography distinguishes itself due to its ability to produce high-quality images consistently and cost-effectively, making it a popular choice for large print runs. The materials used, such as the water rollers that keep the plate moist and the specific inks suited for this method, are crucial to achieving the desired print quality.
