How an image is displayed on a monitor depends on a number of factors. For example, colours and contrasts depend on hardware and software as well as ambient lighting and subjective psychological factors. Therefore, the look of an image may differ from screen to screen. In the case of prints, how colour is reproduced depends on the printing technique, hardware settings, printing inks and the print substrate.
 
In any case, digital works of art also pose a rather fundamental question: What is actually an original? Is what I see as a digital image on a screen the artwork? Is it perhaps just the file containing all the parameters and ready for output to a monitor or a printer?
