Is There A Big Gaps Between Printing Effects of Inkjet Printer's Six Colors and Four Colors?

Is there a big gaps between printing effects of inkjet printer's six colors and four colors? The gap is still there, but it is getting smaller and smaller, and the most critical parameter is the droplet size.

 The 6-color ink was originally developed to solve the graininess. The limit perception ability of the human eye to the ink drop is about 0.8~0.9PL, and it is basically no ink point print below 2PL.


The first 6-color photo printer was EPSON Photo700. At that time, the technology was able to achieve 7PL ink droplets. The size of the ink droplets on the photo paper was very strong, so EPSON increased the graininess of the photo. Light cyan and light magenta, the ink concentration is about 30% of the normal concentration, so that the human eye can see the effect similar to 2PL ink drops. The 2PL ink drops, at the time, almost no ink point printing. Therefore, this has become the standard for Epson to divide Photo and C series.


In 2007, EPSON launched the photo printer Photo 20, which is just a 4-color inkjet printer, but since the minimum ink drop reached the 2PL standard, EPSON also classified it as the Photo series. Other models, whether it is the early COLOR/C series, or the mid-term ME series, or the current L series, even if some models can reach 5760*1440dpi, still can not be divided into the Photo series, the biggest reason is Ink drops ≥ 3PL. But in fact, those models of 3PL are not far from 2PL, so the effect of photo printing is already very good, at least the comprehensive image quality has surpassed the level of the first generation Photo700. Therefore, if the graininess of the photo is not particularly harsh, EPSON's four-color machine (3PL ink drops) is now enough for home photo printing.


Then, CANON, CANON just started the same way as EPSON, and increased the light color to reduce the graininess. But this situation ended in the era of IP4200. The reason is that the minimum ink droplets of the IP4200 have reached 1PL, and it is absolutely unnecessary to use light ink. Therefore, after this, Canon also divided all printers with a minimum ink drop of 1PL into photo grades.



Looking at HP again, HP also started the EPSON route. Until the launch of the 818 ink cartridge, this is HP's first ink cartridge that can use double ink drop technology. The smallest 1.5PL ink droplet also announced the end of HP's six-color printer. . Coupled with the shrinking market in the desktop printing industry, HP even cut off all of the Photosmart series of printers, all of which were handed over to the four-color machine.


Comprehensive status quo: The EPSON six-color machine has a minimum of 1.5PL ink drops, plus two light colors. In theory, the human eye can achieve the effect of 0.45PL, which is far less than the naked eye limit, so that the true ink-free output can be achieved. The effect is that only one of all branded wide format inkjet printers can do it. This is one of the reasons why photo printing prefers EPSON.



We have our own brand of printer, ORIC, and we also agent other brands abroad, such as EPSON, MIMAKI, ROLAND and MUTOH.

We mainly focus on researching and developing high-speed and high-resolution inkjet printers and control system, our printers and accessories have the honor to earn widespread acclaim by the firmly support of the top R&D team and our own technology. Major products are E series water-based printers, R series UV printer, O series flatbed printers etc.
