Which characteristic defines monoprinting?

Monoprinting is distinguished by the creation of a single, unique print from a specific process. This method leverages the application of ink or paint onto a plate, which can be manipulated in various ways before being pressed onto paper, resulting in a distinct image that cannot be exactly reproduced. The essence of monoprinting lies in its ability to produce one-of-a-kind artworks, making each print a unique piece.

The other options describe characteristics associated with different printmaking techniques—such as relief printing, which can produce multiple identical prints, or processes that involve layering materials, which applies to other forms of printmaking like collagraphs or mixed media. Therefore, the defining trait of monoprinting as a technique is that it results in only one unique print, reinforcing the idea that each monoprint is an individual artistic statement.
