Printers and CMYK

Your printer and monitor generate color quite differently. Your printer produces prints using a series of dots in three primary colors: cyan, magenta, and yellow. When equal amounts of these three colors are overlaid, the resulting color is black.

The printer can overlay two colors to produce a third color. For example, magenta and yellow produce red. Cyan and magenta produce blue. It overlays cyan and magenta to produce blue. To produce less saturated colors the printer “mixes” white by leaving some dots unprinted.

Mixing magenta with unprinted dots produces pink.

By overlaying two or more primaries, the printer generates a palette of eight colors. Although equal portions of the three primary colors form black, your printer includes a separate black toner cartridge to produce very dense black for images with a large amount of black text or black backgrounds. These four colors—cyan, magenta, yellow, and black—represent the color system known as CMYK.

Monitors and RGB

Your monitor projects color onto the screen. The three primary colors the monitor projects are red, green, and blue. When equal portions of these three colors are projected, they produce white. These three colors represent the color system known as RGB.

The surface of your monitor consists of thousands of phosphor dots. To produce red, the monitor projects red phosphors. To produce a less saturated hue or red (pink) the monitor turns on two out of three of the red phosphors. Printers add unprinted white dots to produce less saturated colors, while monitors turn on fewer phosphors.

Another important difference between your printer and monitor is the way each one translates light. Paper reflects light, while monitors emit light. Because of these different methods, printers have one range of colors and monitors have a different range of colors.

6250 specifications

The Xerox 6250 is a notable model in the history of photocopying technology, which emerged in the mid-1980s as a part of Xerox's line of high-performance copiers. Designed to meet the demands of small to medium-sized businesses, the Xerox 6250 was celebrated for its innovative features and robust capabilities, allowing it to stand out in an increasingly competitive market.

One of the main features of the Xerox 6250 is its ability to produce high-quality monochrome copies. The machine operates at a sharp resolution of 600 dots per inch (dpi), which ensures that text and images are reproduced with clarity and precision. It can handle a variety of paper sizes and types, including letter, legal, and even larger formats, making it suitable for diverse office needs.

A significant technological advancement featured in the Xerox 6250 is its electrostatic copying process. This technology enhances the overall efficiency and speed of copying, with the machine capable of producing up to 25 copies per minute. In addition, it includes an automatic document feeder (ADF), allowing users to load multiple-page documents for hassle-free copying, further streamlining workflow in busy office environments.

The Xerox 6250 also includes a user-friendly interface, featuring a simple control panel that facilitates easy operation. Users can easily select copy settings and make adjustments as needed, minimizing training time for new employees. Moreover, the device supports automatic duplexing, which enables users to produce double-sided copies efficiently, saving paper and reducing waste.

Another important characteristic of the Xerox 6250 is its reliability and durability. Built with robust components, this copier was designed to withstand the rigors of daily use, making it a trusted choice for many organizations. Maintenance is also straightforward, with easily accessible components that simplify servicing and replacement tasks.

With a compact footprint, the Xerox 6250 can seamlessly fit in various office settings, maximizing space without compromising functionality. Overall, the Xerox 6250 represents a significant step forward in copying technology, combining high-quality output, user-friendly design, and reliable performance, which has led to its lasting impact in the world of office equipment.
