Regular inks can print better than laser, but they are not comparable with BCH medical inks.  BCH medical ink is formulated to satisfy these requirements:

1. Optimized for film printing.  Although BCH's medical ink can be used on both paper and transparent film, we have optimized the ink for the balancing of color reproduction, tonal gradations, and uniform glossiness, and we have more precise control of dry time, spread, and retention.  Therefore, the ink will dry fast and be smear resistant.  Also, the ink will be suitable for long-term storage.  Furthermore, the ink is designed to reduce reflection and enhance transparency control for films.  

2. High resolution and high black-white contrast ratio.  Have you ever wondered why medical films are blue?  It is because inkjet and laser toner are naturally dark brownish/black, so adding a light blue will enhance the dark black and make it “crisp.”  BCH took this into consideration and added particular material to the black, which makes it darker than regular black.  Therefore, we expanded the range from the darkest black to a transparent color, giving a physician’s eye more range to explore intricate details.  Furthermore, we have specially formulated the ink to be used in photo mode printing, which can make the image three to four times sharper than regular ink.

3. Continuous gray.  Contrary to most people's beliefs, printing a black and white (grayscale) image is harder than printing in color.  To make something gray, we would mix equal amounts of cyan, magenta, and yellow.  To make a pure black, we would need all three inks (CMY) printing at the maximum capability.  However, this will result in too much ink on the paper and create problems.  Therefore, a printer will carry a premixed black color and use it just in this situation.  Now, what if we want to print 98% black?  Do we use black or CMY ink?  The printer will make a decision and use mostly black ink and a little bit of CMY.  During this process, the printer carefully calculates the best results for each print mode and paper type used while looking at various image factors including color reproduction, tonal gradations, black density, low graininess, glossiness, anti-bronzing, and anti-metamerism. Mixing ink is not easy, and the result often varies from paper to film.  In many prints, we can see the “banding” problem which is the inkjet transition from mixing colors.

One solution to this problem is to only use black and different shades of black inks.  Although some printers carry a gray ink cartridge to get around the hassle of mixing, BCH takes this idea to the next level.  For BCH's medical ink, we replaced all the colors (CMY LC LM) with specially formulated four to six shades of gray, so the printer is using a more precise color rather than making it on the fly.  Therefore, we are mixing different shades of pure blacks, which give the print a more natural and accurate representation of actual colors.  This way, it can separate subtle differences that may be missed by a regular inkjet or laser.

4. Minimize clogging.  In a fast-paced environment such as the medical field, the chance of clogging should be minimized to the lowest level.  BCH uses triple filtration technology and a nano-filter to make sure the ink won't clog up the printhead.  We also add the BCH wetter solution to prevent the clogging from happening.  We select high-grade dye ink because even if the printhead is clogged, the clog can be easily removed by a printer's built-in self-cleaning function.

5. Safe and environmentally friendly.  BCH ink is non-toxic, leaves no VOA residue, and is safe to be used in a medical environment.
