Often an artist will work on a composition to a certain point and then stop to print an impression of it to consider how it will look in its final appearance. Plates are composed in reverse making states an essential step in creating a final image. This single stage in the evolution of this image is called a state. Each time the composition is changed a new state of the print is created. These changes can range from the addition of a plate signature to drastic alterations in the composition. Today artist's may choose to edition a state before moving on with the composition.
