Competition inkjet printing speed

Although the advantage of jet printing in terms of color and price is prominent, it has not been able to satisfy the efficiency-conscious consumers at the print speed. Recently, Hewlett-Packard introduced the photosmart 8250 photo printer, which uses a new technology that can print a photo in 14 seconds. It can print 32 black-and-white documents per minute. The maximum speed for printing color documents is 31 ppm. "The world's fastest home photo printer." This achievement is completely comparable to the color sensation that now has an imaging technology.
Processor speed, memory speed and size, interface transmission speed, and number of nozzles are the main factors affecting printer speed. The number of inkjet nozzles has always been a secret weapon that merchants use to increase the printing speed of their products. Because HP uses an integrated cartridge, the disadvantage behind the 8250 high speed is that once the supplied cartridge is used up, the user needs to replace the expensive 6-color cartridge; in addition, Canon's new pixma ip2200 is also equipped with a new fine. Ink cartridges have increased the number of inkjet nozzles by 50% compared to the previous version. This means that the print range of each print head can be increased by half, thereby shortening the printing time. In just 55 seconds, it is possible to print high-quality endless 4R photos.
Compared with jet printing, the main advantage of color laser is the fast printing speed. It is believed that with the availability of these high-speed new products in the near future, inkjet printers will also quickly gain advantages in printing efficiency.
Although printing technology is refined, there are many brands that are currently sprayed, but the core technology is only in the hands of a few brands. Epson is the representative of piezoelectric inkjet technology. Because micro-voltage printing technology will affect the printing speed, Epson has developed a "smart drop-dropping" technology. The printer will dynamically control the size of ink droplets according to actual needs in the printing process. This resolves the conflict between print speed and print quality.
In the foregoing, we mentioned that Epson's color reproduction is better. In fact, this is mainly due to Epson's "natural color reproduction technology." This technology has broken through the previous product concept, according to the natural color gamut (srgb color gamut) and print color The corresponding relationship between the two domains, in the printing process to restore the original blue, green and other natural colors, so that the color details are more clear, richer levels, the printed photos are closer to the true color. In addition, the all-real digital video pimii technology that supports the direct connection of digital cameras also effectively solves the problem that the display cannot restore digital photo image data.
HP and Canon are the leading manufacturers of thermal bubble jet technology. The main disadvantage of this technology is that it is difficult to control the direction and size of ink particle jets. Through hard work, currently Canon's ultra-fine ink droplet technology can control the droplet size to 1 picoliter, while HP's fourth-generation Filipino pro technology has exceeded 1 picoliter. This human visual system can distinguish the lowest limit (Epson is 1.5 Slightly higher.
In the control of ink particle jets, Canon used four-fold color control technology, and HP used a rich-image layering technology. In addition, Canon's photo-realistic technology is similar to Epson's "natural color reproduction technology," and HP's intelligent color enhancement technology allows users to adjust print parameters without having to bother to easily obtain the best results on various print media. .
