The process reproduces images or text using only shades of gray, ranging from black to white. Instead of employing color inks, this technique relies solely on varying levels of black ink or toner to create different tones. A common example is photocopying a color document, which typically results in a monochromatic representation using various shades of gray.
This method is crucial for reducing printing costs, especially when color is unnecessary. It also offers advantages in situations where color fidelity is not essential, or when printing documents intended for archival purposes, as monochrome prints tend to be more stable over time. Historically, this technique predates widespread color printing, playing a significant role in early photography and document reproduction.
