Can a color inkjet printer print photos? Thank you, and God bless you. Ordinary color inkjet printers can print photos with low requirements with special photographic paper. If the requirements are higher, you may use better photographic paper and high-resolution pictures.

Ink jet printers can be divided into two types according to the working mode of the print head. At present, inkjet printers can be divided into piezoelectric inkjet technology and thermal inkjet technology according to the working mode of print head.

Piezoelectric inkjet technology uses the principle that it will deform under the action of voltage. Piezoelectric ceramics expand and contract with different voltages, so that the ink in the nozzle can be sprayed on the interface. This technology is unique to Epson.

Thermal inkjet technology is that under the action of strong electric field, part of the ink in the nozzle pipeline vaporizes to form bubbles, and the ink is ejected to the interface by using the pressure of the bubbles.

Will the newly bought inkjet printer provide ink? What kind of inkjet printer is good? Thank you. All newly bought printers have random ink cartridges with ink in them. As for what is a good printer, it depends on your requirements and price. What suits you is the best, and you will get what you pay. At present, the brands of inkjet printers are Canon, Hewlett-Packard and Aipu, all of which are first-line brands. From the point of view of convenience and saving money, we can consider Epson's and modify the continuous supply. Gao Qiao Computer World 2C94 Red Square Technology. make arduous efforts

Printer, computer sales, home maintenance. The price is real. .

How often is it better to clean the nozzles of inkjet printers? Thank you, and God bless you. If you always buy original products, you don't have to pay attention to this function, and the substitutes are not so bad ... If they are equipped with continuous ink supply devices, it is best to clean them once a week.

Which 6-color inkjet printer is better? There is no specific good, printer, to put it bluntly, it is a penny for a penny; Epson is the person who uses it the most, and the quality of Epson itself is also good;

There are ordinary photo printing and commercial printers, which are more expensive, but the printing effect and printer quality are better; If the requirements are not high, buy ordinary photos to print, such as R330；;

What is the inkjet principle of inkjet printer? According to the working principle, inkjet printers can be divided into solid inkjet and liquid inkjet (the latter is more common now), and liquid inkjet can be divided into bubble inkjet (Canon and Hewlett-Packard) and liquid piezoelectric inkjet (Epson). Bubble jet technology is to heat the nozzle to make the ink generate bubbles and spray them on the printing medium. Similarly, HP's thermal inkjet technology uses thin film resistors to heat less than 0.5% of the ink in the inkjet area to form bubbles. This bubble expands at an extremely fast speed (less than 10 microsecond), forcing ink droplets to be ejected from the nozzle. The bubble continues to grow for a few microseconds and then disappears back into the resistor. When the bubble disappears, the ink in the nozzle retracts. Then the surface tension will generate suction, and the suction will attract new ink to replenish the inkjet area. Thermal induction inkjet technology is composed of such an integrated recycling technology scheme. In piezoelectric inkjet technology, ink is ejected from a nozzle similar to thermal induction inkjet technology, but ink droplets are formed by narrowing the area where ink is ejected. The contraction of the ejection region is controlled by applying voltage to one or more piezoelectric plates in the ejection region. Because the ink is prone to chemical changes at high temperature and its properties are unstable, the authenticity of the printed color will be affected to some extent; On the other hand, because the ink is ejected by bubbles, it is difficult to grasp the directionality and volume of ink particles, and the edges of printed lines are easy to be uneven, which affects the printing quality to some extent. These are its shortcomings. Micro-piezoelectric print head technology uses the characteristics of crystal discharge under pressure to stably eject ink at room temperature. Strong ink drop control ability, easy to achieve 1440dpi high-precision printing quality. In addition, when using micro-piezoelectric inkjet, the ink will not change chemically due to heating, so the requirements for ink are greatly reduced. At present, liquid inkjet printers produced by Epson, Hewlett-Packard and Canon represent the mainstream products in the market.

At present, there are three common printers on the market: needle printers, inkjet printers and laser printers. The stylus printer has passed its glorious period and gradually entered dusk; Although the price of laser printers is declining, there is still a certain gap compared with mainstream color inkjet. If color is used, the price will be much higher. In this way, it is not surprising that inkjet printers have recently become popular for half the sky.

Ink-jet printer is developed after needle printer, which adopts non-impact working mode. The outstanding advantages are small size, simple and convenient operation, low printing noise, and the use of special paper can also print pictures comparable to photos. After several years of tempering, the technology of inkjet printer has made great progress. Back in 1995, a color inkjet printer cost about 4,000 yuan, and the beauty printed could be as rough as Wang Er's pockmarked skin. Up to now, the color inkjet printer with a price of 1000 yuan is enough to meet all the needs of ordinary families. Even users who have a high demand for image quality like photographers can find ideal products in color inkjet printers with a price of more than 2,000 to 3,000 yuan.

At present, inkjet printers can be divided into piezoelectric inkjet technology and thermal inkjet technology according to the working mode of print head. According to the material characteristics of inkjet, it can be divided into water-based materials, solid ink and liquid ink printers. Let's explain it separately.

Piezoelectric inkjet technology is to place many small piezoelectric ceramics near the nozzle of the inkjet printer, and apply voltage to them in time by using the principle that they will deform under the action of voltage. The piezoelectric ceramics expand and contract, so that the ink in the nozzle is ejected and a pattern is formed on the surface of the output medium.

The cost of inkjet print head made by piezoelectric inkjet technology is relatively high, so in order to reduce the use cost of users, the print head and ink box are generally made into separate structures, and it is not necessary to replace the print head when replacing ink. This technology was originally created by Epson, because the structure of the print head is reasonable, and the size and usage of ink droplets can be effectively adjusted by controlling the voltage, so as to obtain higher printing accuracy and printing effect. It has a strong ability to control ink drops and is easy to print with high precision. Now the ultra-high resolution of 1440dpi is maintained by Epson. Of course, it also has shortcomings. Assuming that the nozzle is blocked during use, the cost of dredging or replacing it is relatively high and it is not easy to operate. Maybe the whole printer will be scrapped. At present, the products using piezoelectric inkjet technology are mainly inkjet printers of Epson company.

Thermal inkjet technology is to let ink pass through a tiny nozzle. Under the action of strong electric field, some ink in the nozzle pipeline will vaporize to form bubbles, and the ink at the nozzle will be sprayed onto the surface of the output medium to form patterns or characters. So this kind of inkjet printer is sometimes called bubble printer. The nozzle manufactured by this technology has mature technology and low cost, but the electrode in the nozzle is always affected by electrolysis and corrosion, which will have a lot of influence on the service life. Therefore, the print head using this technology is usually manufactured together with the ink cartridge, and the print head is updated while replacing the ink cartridge. In this way, users don't have to worry too much about nozzle blockage. At the same time, in order to reduce the use cost, we can often see the situation of injecting ink cartridges (filling ink). After the print head finishes printing ink, fill the special ink immediately. As long as the method is proper, you can save a lot of consumables.

The disadvantage of thermal inkjet technology is that the ink will be heated during use, and the ink is prone to chemical changes at high temperature and its properties are unstable, so the authenticity of the printed color will be affected to some extent. On the other hand, because ink is ejected through bubbles, the directionality and volume of ink particles are difficult to grasp, and the edges of printed lines are easy to be uneven, which affects the printing quality to some extent, so the printing effect of most products is not as good as that of piezoelectric technology products.

There are many products using thermal inkjet technology, mainly used by Canon, Hewlett-Packard and other companies.

Solid-state inkjet printer is Tektronix's patented technology. The phase change ink it uses is solid at room temperature. When working, the wax-like pigment block is heated and melted into liquid, and then it works according to the above-mentioned inkjet method. The advantage of this printer is that the pigment has good water resistance, and there is no problem that the print head is blocked due to the drying of ink. However, at present, the production cost of printers using solid ink is relatively high, and there are few products.

Inkjet printer is divided into two parts: mechanical part and circuit part. We mainly look at the mechanical parts, which usually include ink cartridges and nozzles, cleaning parts, font machines, paper feeding mechanisms and sensors. There are two types of ink cartridges and nozzles, one is a two-in-one structure, and the other is a split structure. These two methods have their own advantages. Cleaning system is the maintenance device of nozzle. Word carriage machinery is used to realize printing position positioning. Provide paper conveying function to the letter organization, and it must be well coordinated with the letter conveying machinery to complete the printing of the whole page. The sensor is specially designed to check the working conditions of various parts of the printer.

In order to facilitate everyone to have a more comprehensive understanding of inkjet printers, we have summarized the main performance indicators reflecting the performance differences below for your reference when purchasing.

L, resolution

DPI is an important standard to measure printing quality in the industry. It itself shows the number of dots that an inkjet printer can print in an inch. When printing in monochrome, the higher the dpi value, the better the printing effect. When printing in color, the situation is more complicated. Generally, printing quality is affected by dpi value and color coordination ability. Because the black-and-white printing resolution and color printing resolution of general color inkjet printers may be different, you must pay attention to what kind of resolution the merchant tells you when buying, and whether it is the highest resolution. Generally, you should choose an inkjet printer with at least 360DPI.

2, color coordination ability

For users who use color inkjet printers, the color harmony ability of printers is a very important indicator. When traditional inkjet printers print color photos, if they encounter transition colors, they will choose a close combination of three basic colors for printing. Even if black is added, this combination can't exceed 16, and the color scale performance is not satisfactory.

In order to solve this problem, early inkjet printers used the method of adjusting the density of spray points to represent the color scale. However, for the products with a color resolution of only about 300dpi at that time, the result of adjusting the density is that the transition color effect is very poor and there will be many spots. At present, color inkjet printers, on the one hand, make the printed dots finer by increasing the printing density (resolution), thus making the picture more delicate; On the other hand, they all improved their own technology in color harmony, such as increasing the number of colors, changing the size of ink droplets, and reducing the basic color density of ink cartridges. Among them, increasing the number of colors is the most effective at present. Usually, five-color ink cartridges are used, and the original black ink cartridges form so-called six-color printing. The number of tones obtained by this arrangement and combination is improved many times at once, and the effect is obviously improved.

The principle of changing the size of ejected ink droplets is to eject ink droplets with standard size in places with high color density and eject small ink droplets in places with low color density during printing, which also realizes more color levels. Reducing the color density of ink cartridges is actually to form more color levels by repeated inkjet in places with high color density.

3. Impression speed

The printing speed of an inkjet printer is generally calculated by the number of pages printed per minute (ppm). However, because the print volume of each page is not exactly the same, this figure will definitely not be accurate, just an average figure. For home printers, because the printing volume is generally not too large, it is not necessary to pay special attention to the printing speed when purchasing.

4. Print driver

Print driver is a very important but often neglected link. Many advanced printing technologies are closely related to supporting printing technology. Please be sure to use the original driver from the manufacturer and pay attention to the update at any time.

5. Print format

Ordinary inkjet printers have A4 and A3 printing formats. Ordinary home users can use A4 format.

Why is the color printed by the six-color inkjet printer lighter than that displayed by the computer? Thank you, and God bless you. Because there is mutual adaptability among printer, ink and printing medium, the most common method now is to match ICC curve with all connected factors in the printing process. Ask those who sell printers or ink. They all know curves.

What are the inkjet technologies of inkjet printers?

There are two main technologies used by inkjet printers: continuous inkjet technology and random inkjet technology. Both early inkjet printers and current large format inkjet printers use continuous inkjet technology, while current popular inkjet printers generally use random inkjet technology. The continuous inkjet technology is represented by the charge modulation type, and the ink in the random inkjet system is only ejected when printing is needed, so it is also called the on-demand type.

Continuous inkjet

Continuous inkjet technology is represented by charge modulation type. The principle of this kind of ink-jet printing is to apply a fixed pressure to the ink in the nozzle by using a piezoelectric driving device to make it spray continuously. When recording, the vibration signal of the oscillator is used to excite the jet to generate ink drops, and the size and spacing of the ink drops are controlled. The printing information from the character generator and analog modulator controls the charge on the telegram to form charged and uncharged ink drops, and then deflects the electrode to change the flying direction of the ink drops, so that the ink drops that need to be printed fly to the paper, resulting in character/graphic records. Ink drops that do not participate in recording are recovered by the catheter. For deflection electrodes, some systems use two pairs of deflection electrodes perpendicular to each other to deflect the printing position of ink drops in two dimensions; Some systems use multidimensional control for deflection electrodes, that is, multidimensional deflection type.

This continuous circulation inkjet system can produce high-speed ink droplets, so the printing speed is high, and ordinary paper can also be used. Different printing media can obtain high-quality printing effect, and it is easy to realize color printing. However, compared with the random type, the structure of this inkjet printer is more complicated: the ink needs a pressurizing device, and the terminal needs a recycling device to recycle, and does not participate in recording. The working mode is not efficient and accurate. Inkjet printers using this technology are rare.

Random inkjet

In a random inkjet system, ink is ejected only when printing is needed, so it is also called inkjet on demand. Compared with continuous type, it has the advantages of simple structure, low cost and high reliability. However, due to the influence of ejection inertia, the ejection speed of ink drops is low. In this random inkjet system, in order to make up for this shortcoming, many random inkjet printers use multi-nozzle to improve the printing speed. Random inkjet technology mainly includes two categories: micro-piezoelectric type and thermal bubble type:

Hot bubble inkjet technology

Inkjet printers usually use hot bubble inkjet technology. By heating, expanding and compressing the ink in a short time, the ink is sprayed on the printing paper to form ink dots, which increases the stability of ink droplet color and realizes high-speed and high-quality printing. Because the consistency of droplet shape and concentration will have a great impact on image quality except droplet size, and the direction and shape of droplets generated at high temperature are not easy to control, so high-precision droplet control is very important. The principle of thermal bubble inkjet printing is to put ink into a very tiny capillary and quickly heat the ink to the boiling point through a tiny heating pad. In this way, a very tiny steam bubble is generated, and the expansion of the steam bubble ejects a drop of ink to the top of the capillary. When the heating is stopped, the ink cools, which leads to the condensation and contraction of steam, thus stopping the ink flow until the steam is generated and ink droplets are generated next time.
