What does a printing press do?

A printing press is a machine specifically designed to transfer ink onto a printing medium, such as paper, fabric, or other materials. This process is essential for creating prints, whether for books, posters, or other printed materials. The printing press operates by applying a controlled amount of ink to the surface of the medium, ensuring that the ink is distributed evenly. This capability is crucial for achieving high-quality prints that are consistent in color and clarity, making it a vital tool in the field of visual communications and multimedia design.

The other options relate to tasks that are not functions of a printing press. Creating digital designs is typically done using design software on a computer. Calculating print costs involves project management and budgeting processes, while storing design files is a function associated with file management systems or cloud storage, rather than the printing mechanism itself.
