The EPSON nozzle technology reveals as an economical, effective color printout device, and inkjet printers have been familiar with many users. Especially with the development of digital imaging technology, the concept of making digital photos has gradually been accepted by the majority of home users, and there is a new world of implementing skills with printed color.
What is the reason for the inkjet printer to output a beautiful photo and picture? How is the difference between print quality between different models? Discussing these problems, it is necessary to talked from the core - nozzle of the inkjet printer, talked from the formation process of each ink droplet.
First of all, it is necessary to clarify a problem: printing accuracy is not the basic technical indicator of inkjet printers. During the development of the inkjet printer, printing accuracy has always been a technical indicator of users, and the manufacturer also focuses on this. Indeed, from 360DPI, 600DPI, 720DPI, 1200DPI, 1440DPI to the current 2880DPI now, and the continuous improvement of printing accuracy has leaving print quality. However, simple DPI numbers cannot explain the most fundamental issues of print quality. The DPI represents how many ink points can be printed within an inch, and if we don't consider the problem of mutual coincidence between the ink points, this description DPI number can be improved informably, and the print quality will not increase, even decreased. Therefore, to effectively improve the value of the DPI, there must be a sufficiently small ink point as a premise, that is, a sufficiently small ink droplet volume. Only when the ink droplets are small enough, the implementation of higher printing accuracy is true, and it is possible to play a role in improving the final print quality.
In addition, we know that inkjet printers are similar to the display device, the printing device is similar, and the multi-color color of the limited pigment is shown in the world, and this arrangement is not random, it is obtained by precision calculations. . Since it is calculated, there is definitely a hypothesis that all ink points can be arranged on paper (or other media) in accordance with certain rules, and the shape of each ink point is substantially consistent, and foreseeable. If the paper position of the ink droplets cannot be accurately controlled, or the formed ink is too irregular, or when the ink point is formed, some "satellite" ink droplets (some conventional bubble spraying) are splashing in the surrounding position. Ink printers often have such problems), then the calculation of high-precision level can only be tanded. On this basis, higher printing accuracy (DPI) does not really increase the final print quality.
Therefore, reduce the volume of ink droplets, accurately control the paper position and ink point shape, reduce the splash of ink droplets, and become an important footprint of the inkjet printer manufacturer in improving print quality. In this regard, EPSON is one of the most successful manufacturers.
EPSON uses a different microphic electric nozzle technology to control the piezoelectric device by electrical pulse signal, forming a corresponding size to the ink, so that the corresponding volume of ink droplets are ejected from the nozzle. Compared to the traditional thermal bubble nozzle technology, the control of the ink droplet volume is more accurate because of the control, the control of the ink droplet volume is more accurate. At present, many models of EPSON have several minor ink volumes have reached 4 microliters. The individual models have reached a record 3 micro-liter, which is also possible to have new products for their new 2 micro-lifting drops. roll out. It is these industry-leading indicators to ensure that EPSON products can realize real high-precision printing.
In terms of ink droplet control, the microstatic mode has some congenital special advantages. We know that due to the small droplet, the ink nozzle is very fine, more than the head. In such a subtle part, the surface tension of the ink liquid surface at the nozzle is very considerable, and the shape of the ink droplet is irregular, and the ink droplet splash is largely the tension of this liquid level. The conventional bubble nozzle is a local heating of the ink, which is bubble, bubble burst, and the ink is ejected from the nozzle. This approach is less than the above problem. The microgmatic mode is due to the * piezoelectric chip control, and the ink droplets can be pulled backwards, and then it is emitted out, just like the arrow of the string, the ink point of the ink is very round. This is definitely unable to achieve a bubble nozzle. According to * push and pull the two directions, the microstatic electric nozzle can achieve a unique liquid level control technology, minimizing the effects of liquid tension on the shape of the ink droplets, and does not form splash while also makes ink The drip jet is stable, and the paper position of the ink point is more accurate. It is because of these technical features, the ink point printed by the EPSON microstatic printhead is arranged in an orderly, shape unified, and there is no extra splashing ink point, so that the final print color is accurate, the level is delicate, and the performance is Strong.
Of course, there are other characteristics of microstatic ink jet technology, such as the ability to accurately achieve intelligent ink droplet transform, etc., this is no longer detailed.
Finally, it will be said that many people have a misunderstanding: the higher the number of nozzles in the printhead, the higher the print quality. In fact, the number of nozzles in the printhead is independent of printing accuracy and print quality. It is theoretically, even if there is only one nozzle, it can also achieve any high DPI value. The purpose of increasing the number of nozzles is to increase the printing speed. It must be pointed out that there are many factors affecting the printing speed: there will be different speeds, of course, there will be different speeds; different types of nozzle injection frequencies will be different; the difference in printing algorithm; whether to apply intelligent ink droplets conversion technology; paper feed speed, etc. Wait. In summary, the number of simple nozzles cannot be explained.
HP printer accumulates 20 experience and find colorful new way out
"This is the best era, and it is also a worst era." Dickens describes the ages at the time in "Double City". So far, HP printers have 20 years of history. For 20 years, the printer has developed into very mature IT products, all around us. So, what kind of printer products in HP eyes are in the age? Recently, HP convened a colorful business strategy conference for the theme "more wins and forthing and going to step by step", which announced that 2004 color business will enter the mainstream, and announce a complete set of color business strategies to actively promote color business. The popularity of users. HP relys in 20 years of experience in printing and imaging, and $ 1 billion in R & D fees worldwide, as well as 60 million US dollars in the Asia-Pacific region, will strive to help users break through the past, and let colorful colors integrate into their business. To make companies benefit from color business. 20 years of gestation strategy for 20 years, for a person, the spirit of the positive youth, the spirit of strong, and the vitality of the vibrant is characteristic of this stage. This is also true for HP printers. Michael Hoffmann, Senior Vice President, HP Asia Pacific and Japan Printing and Imaging Group, said: In 1984, HP launched a monochrome desktop laser printer, which was just 20 years; the HP colored laser printers debuted in 1994, so far, it has been in 10 years, developed to this day HP creates another miracle in the printer field. At the same time, the development of 20 years is a watershed in the HP printer. The user's demand for printouts has changed, and it is not a fact that the black and white steering color is already unexpected. To this end, at this time, HP launched a holistic strategy for colorful business. The entire strategy includes three parts, in addition, there is a combination with other vendors; in the inside, there are deep excavations of their own resources to meet the needs of different levels of consumers in color commerce. First, HP works with Apple, Adobe, Microsoft and QUARK to work together to provide a hardware and software colorful business solution from the office area to the professional field. Second, provide new color printing solutions. Such as HP is launched to the Asia Pacific market, the first price below $ 500 is less than $ 500, Color LaserJet 2550L, for SME users. Third, it is also the most important point, improve and improve print quality. HP will introduce new print paper, including laser print special media, whether it is printing office routine document, or a formal marketing material, HP can provide professional print quality and * sex. Michael Hoffmann said: "Hewlett-Packard will bring more comprehensive color experiences for all customers. The prices of printing and imaging equipment have gradually accepted by users, and the technology itself has become increasingly mature and can meet customers' demand in color business. "Color popular disorder no longer exists
Michael Hoffmann uses several keywords to describe the misunderstanding of the user's color business: "Too expensive, too complicated, too large, too slow." However, is the current state?
According to HP, the $ 7.1 billion color business printing market will increase in 20% per year, and in 2006, the global market will reach $ 10.2 billion. Chen Tachipous, Vice President, HP Asia-Pacific and Japan Printing and Image Group, and the vice president of the major, said: "Now, the enthusiasm of users is increasingly enthusiasm. Economy, easy to use, high image quality and high performance, is already satisfactory Easy important factors in color business experiences, HP products and their programs have completely have these factors. "The release of this color business strategy strategy makes the epitaxial of traditional color business concepts to expand: color business users are divided into four Class - SMEs, large enterprises, graphics image fields, and commercial printing, the user is all-round. Office staff will no longer happen, because using HP print solutions are not only fast, economical, and easy to use; for marketing and sales professionals, HP color printing solutions can help them make marketing materials, with more beautiful The professional data responds to customers faster; for art designers and publishers, through HP's equipment, technology and workflows will gain consistent color performance and professional image quality; while market staff will also follow HP on-demand Printing solutions have benefited a lot, making it a specific activity or short-term publicity material, making it possible to achieve real-time target marketing activities.
User needs are the core facing such complex user types, how does HP meet their needs one by one? To this end, Michael Hoffmann describes an equilateral triangle for the reporter: The center of the triangle is the user, and the three sides are composed of "high-tech, cost-effective, best customer experience". This is the HP face to personal and corporate consumers. The purpose of product and solutions. Specific to different groups, HP has also developed different strategies. For large and medium-sized enterprises, HP launched the slogan of "Demand More", that is, HP delivery to corporate users is more responsibility, greater flexibility and better rewards based on IT investment. For SMEs, HP launches the slogan of "get more", that is, HP provides stronger * sex, more service and support, more localized and priced more competitive. SMEs are relatively sensitive to prices. In addition to providing them with complete product lines, it is more important, stable cost-effective products in promotion, and is also one of the characteristics of color printing products in China. Family consumers, HP launched the slogan of "Enjoy More", enabling consumers to get a digital experience, feel complete solutions for HP's digital images and digital entertainment. HP strives to realize innovation to meet the needs of users and provide different products and solutions for different users. In order to achieve its own strategic objectives, HP has also developed special strategies and philosophy, striving to cultivate markets and promotion products with more effective means, and ultimately contributing to colorful business. The unbeaten equity triangle This is the best era, or a worst era? For HP printers, I want to find the answer. When everyone complains about the overall sluggish IT industry, have you seen companies such as HP printers grow in a year? When everyone is complaining that the profit of the IT industry has been inexperitative, have there been a great popularity of IT products and bringing convenience and enjoyment to consumers? When it is difficult to meet for the user's needs, if you realize that under the traction of user needs, the entire IT industry has a daily change in the day, and this change is so exciting? The Chinese have a customary language called "Square in the people, the work is in the sky", but the back is tight, it is "human custom day". If you can grasp the user needs, comply with the user needs, whether 20 years of HP printers, or a 40-year HP printer, or a longer year, will have a new life, glow, more attractive color. The whole interview process is the most impressive thing is the "equidistant triangle". I think, if a company implements the most thorough, most lastmost, fixed-energy time, and timely, time to time. The best and the worst is always relative. HP's combined HP Adobe is working with business users, HP and Adobe, in order to print Adobe's work, on the one hand, with Adobe's PDF document solution provides a color experience for business users, on the other hand, help the market with ICC standards Personally achieve color output. The cooperation between HP Apple HP and Apple has taken a long time to enhance support to the MAC platform in color printing and imaging, and establish a common standard for color printing and imaging. HP also provides solutions that support Mac OS X and Colorsync, as well as support for professionals and consumers in various market segments. HP Microsoft HP and Microsoft combine their respective color business expertise, providing internal print solutions for SMBs (SMB). HP customers will also get the CD of the business kits due to the purchase of some models of printers to help users make and print marketing documents.
HP QUARK In the field of color management and user-end solutions, QUARK and HP are working together to conduct a series of color business plans, including QUARK applications on HP printers, fully support HP professional color printing technology including CMYK Plus. In addition, HP's DesignJet series printers have become the first printer for QUARK certification.
