Adjustments made to the monitor

If you have high quality monitor capable of finely controlling the amount of light allocated to each component of the RGB mix of colors, it is possible to adjust the colors appearing on the screen in such a way as to approximate the printed result. However, normal monitors allow only rough control of brightness and contrast, control which is applied indiscriminately to the entire screen and is not very effective for anything more than rough adjustment of the appearance of whole screen images. We recommend selection of a highly reliable monitor which suffers from as little deviation in the reproduction of colors as possible.

Some software applications allow you to adjust the Gamma value, a value which adjusts the contrast of a color. One rule of thumb holds that a monitor Gamma value of about 1.4 brings the colors displayed on a monitor into close agreement with the colors displayed on the printed page.

Adjustment of color from within software applications

When the software application allows adjustment of color, the appearance of colors on the monitor screen can be adjusted after comparison with printed results.

Normally, colors are adjusted according to the procedure outlined below. For further information about how to adjust colors, see the documentation accompanying your software application.

First, print out a color sample using the CMYK method, and adjust the colors appearing on the monitor screen as you compare them to the printed result. This process is called color calibration. By performing this calibration, it is possible to bring the colors displayed on the monitor screen and on the printed page into closer match.

If your software application uses a color palette to set color levels, it is possible to finely tune

zthe appearance of a particular color by adjusting the color palette.

If your software application permits you to adjust the colors over the entire screen through use of a color balance, you can make adjustments like washing out red colors or strengthening yellows over the entire screen at a single stroke.

BJC-50 specifications

The Canon BJC-50 is a portable bubble jet printer that made waves in the early 1990s for its compact design and high-quality output. Launched by Canon in 1995, it appealed to both home and business users who required mobility without compromising on performance. This printer offered a unique blend of features that set it apart from traditional desktop printers of its time.

One of the standout features of the BJC-50 is its lightweight and compact form factor, making it an ideal choice for users on the move. Weighing in at a mere 3.5 pounds, it easily fits into a travel bag, allowing professionals to print documents wherever they are. Its small footprint means it can be used in tight spaces, a significant advantage for home offices or small workstations.

The technology behind the BJC-50 is rooted in Canon's bubble jet printing technology. This involved heating ink to create tiny bubbles, which then forced droplets of ink onto the paper to create sharp text and vibrant images. This method delivered higher resolution printing compared to many pen and dot matrix printers at the time. The BJC-50 produced prints at a resolution of up to 600 x 600 dpi, resulting in clear and detailed documents.

Additionally, the Canon BJC-50 featured a flexible inkjet cartridge system. Users could choose between different cartridges optimized for text or photo printing. This adaptability allowed for a range of printing tasks, from basic black and white documents to full-color graphics. The printer also supported both standard and high-capacity cartridges, providing users with options depending on their printing volume.

Connectivity was another strong point of the BJC-50. It came equipped with a parallel port and offered optional infrared capabilities, which facilitated wireless printing from compatible devices. This feature was particularly novel in the 1990s, showcasing Canon's commitment to advancing user convenience and technology.

In terms of usability, the BJC-50 had an easy-to-use interface with straightforward control buttons. It featured a compact and accessible paper tray that could handle various media types and sizes, which made the transition between different printing tasks seamless and efficient.

All in all, the Canon BJC-50 was a pioneering portable printer that encapsulated the demands of its era, balancing size, technology, and functionality. While newer models have since taken the stage, the principles that guided the design and features of the BJC-50 continue to influence portable printing solutions today.
