There are a large number of computer inkjet printers on the market, such as HP, Epson, Canon, Roland, Mimaki, Mutoh, DGI, Infinity, Scitex, Nur, Vutek, and domestic large-scale inkjet printers. In addition to the width and speed, the characteristics of the ink are also highly devious. So how many types of ink can be sprayed? How to choose ink with different models? What is good ink? Do you not use other inks other than the original ink? Does the inkjet agent have the right to prevent customers from switching to other inks instead of providing maintenance services? Why can the ink price be so different? Is the ink safe? Let us talk about it here.
Type of ink
When it comes to the type of inkjet ink, it should start with the structure of the ink head. In fact, the ink head can be divided into two types: thermal head and piezoelectric (Piezo head). Peizo also has high precision and low precision. For example, EPSON nozzles are highly accurate, while Xaar and Spectra nozzles. Belong to low precision, the former is mostly used for water (Water Base) Dye and Pigment inks, the latter are mostly Solvent base Pigment inks. But recently there has also been a new ECO Ink that is actually an environmentally lightweight version of Solvent Ink, commonly known as Mild Solvent or Light Solvent. It can be mainly used on Epson's high-quality nozzles. The quality of inkjet images can be compared with water machines. It can also be used as uncoated materials. It can also prevent UV rays. It is suitable for outdoor display. It is the darling of a new generation of inkjet paintings. Generally Solvent and water-based expensive. Others include Dye Sublimation inks, which can be used to transfer inkjet images to different products, such as T-shirts, porcelain cups, coasters, ceramic tiles, curtains, etc., through endless creativity. UV Curable ink is also a new force that cannot be underestimated, but due to the huge investment in machinery and ink, it is not yet a climate.
Ink selection
The ink selection is determined by the characteristics of the nozzle and the needs of the customer. Generally, the ink of the inkjet machine is Dye or Pigment of Water Base. The particles of the water-based Dye ink are relatively fine, and the quality is easy to control. The chances should not be too great. Therefore, there is also a large supply and choice in the market. Customers only need to pay attention to the color matching and whether it is easy to fade. However, Pigment's particles are relatively large. If there are problems in the production process and quality control, the chances of the plug are large, the chances of painting are unstable, the quality and color of the spray are not as good as ideal, and many customers are deterred. Ink needs to be coated with coating materials, and the production cost is high.
Unknown impurities were found in inferior inks, causing plugging.
Most of the large outdoor paintings on the market are sprayed with solvent ink. The machine width ranges from 1.8m to 5m, and the solvent has strong characteristics. It can penetrate into uncoated adhesive tape and real-time stickers. The ink has good adhesion, is not easy to wear, has low cost, and can be placed outdoors for 2-3 years, which is the first choice for mass production. Microsolvent ink is a lightweight version of strong solvent ink. It has a weak ability to penetrate into the non-coating layer. However, it is generally applicable to both rubber canvas and real-time stickers. Although it can not be like solvent ink, more materials can be selected, but the inkjet quality is better. It is comparable to water-based inkjet printers. In fact, the ink head is matched with the water-based Piezo (piezoelectric) sprayer. The only difference is that the ink supply system needs to have the characteristics of anti-solvent and rot, otherwise there will be ink leakage and plugging.
Oily inks are similar in smell and appearance to the solvent. Generally, laymen think that oily inks require coated materials, so the range of materials that can be used is relatively narrow. Most of the oiliness on the market is Dye Base ink, which is weak in anti-UV function, so it is not popular.
The characteristics of UV Curable are similar to those of water. The chance of the plug is very small, but the ink needs to be exposed to UV light to dry the material, although no special coating material is needed, but the color It is filthy and expensive, and it is not yet very popular. Dye Sublimation is an alternative to ink. It can transfer inkjet images to clothes and small products through heat transfer. It has great potential for development, and there is no special modification of the machine. , can be used.
How to evaluate ink quality
In addition to the ink, the quality and stability of the ink will directly affect the performance of the inkjet machine. But how do you assess whether the ink is right for your machine? First of all, the ink head of the inkjet printer is the most important and expensive part. If the quality of the ink causes frequent plugging, it should be stopped immediately to avoid damage to the nozzle.
Different nozzles must be fitted with the appropriate ink, otherwise the structure may be damaged.
The reason for the general ink plug is mostly due to the fact that in order to save costs during manufacturing, the filter is not delivered to meet the required requirements, resulting in excessive particles; or in the packaging process, there is no qualified dustproof measures. So that the dust impurities in the air are mixed into the ink. These causes can affect the ink supply system of the printer and cause a plug. Secondly, of course, we must pay attention to the color of the ink, the adhesion to different materials and the ability to prevent UV.
When you find the right ink, there is another place to pay attention to, especially the general Asian and domestic suppliers; the first two batches of ink will be better, the following may be less stable, so the reputation and equipment of the ink manufacturer It should also be considered. Because the production of ink is not only accurate, but also the production environment and quality inspection are particularly important.
As far as I know, many Asian countries, especially domestic ink producers, only control the production costs. They often want to attract buyers with low-cost money, cut corners, use low-cost pigments and industrial solvents, regardless of the safety of inks. Quality inspection, production of some low-cost ink. Although the ink on the surface is the same as normal, after testing, it is not difficult to find some chemicals that are extremely harmful to the human body, such as 2-Ethoxyethyl Acetate (ethylene glycol) and Cyclohexanone (cyclohexanone). The ink is easy to stick to the uncoated material, and the price is low, which is a very effective solvent, so it will be used in large quantities. However, because these substances are too toxic, Europe has minimized its use. For example, its large manufacturer BASF has also completely stopped producing this chemical. Some medical cases have shown that inhalation of these chemicals can cause miscarriage in pregnant women and serious damage to male fertility. Working in these environments for a long time, in addition to causing great damage to the respiratory tract and cardiopulmonary function, can also lead to cancer. In fact, most of the inks produced in Europe use the human body's acceptable Latic Acid as the basic agent. Although the production cost and technology are high, the damage to the human body can be minimized, and the international standard should be chosen carefully, so as to avoid saving. Money, lost health.
Ink safety
As mentioned above, ink is more expensive. In addition to the production cost, whether the manufacturer has strict calibration of the ink and whether the test equipment is perfect will affect the stability and quality of the ink. In general, major European manufacturers can provide a Material Safety Data Sheet (MSDS), which not only analyzes the composition of ink, but also displays safety standards. There must be a “Risk Phrase” crisis index. Indicate the extent to which the ink affects the human body and what to pay attention to. However, if the MS is found to have the 2-Ethoxyethyl Acetate mentioned above, its "Risk Phrase" is R60-61, which shows that the toxicity is very strong: R60 - long-term inhalation of pregnant women will cause miscarriage and R61 - affect male reproductive function.
This information is especially important to users because it tells you whether the inks you choose will affect the safety of individuals, employees, and even your family. So before you choose ink, you must understand their ingredients before making a choice. Especially in the environment of Hong Kong, the general office ventilation system may not be able to cope with these highly toxic solvent inks, which may lead to more serious consequences.
In addition, some MSDSs issued in Asia and China have recently been found to have a large distance from the actual ink composition in order to enter the European market. Therefore, when verifying MSDS data, you must be careful to verify, otherwise it may be difficult to escape poison. In fact, the MSDS of the major European manufacturers is credible because their monitoring system is perfect, the legislation is clear, and it is absolutely unambiguous. Moreover, the verification process is rigorous and the test equipment is perfect. Although the price is higher than that of Asia and China, the quality and stability are worth the money.
Ink and maintenance
Due to fierce market competition, users have chosen alternative inks because there will be a large distance from the original ink price. If it is suitable, in addition to cost savings, it is basically the same as the original. However, many manufacturers of spray machines refuse to perform maintenance duties on the grounds that they do not use original ink to damage the machine. Users are worried that they will lose the right to maintain the machine. Even some suppliers want users to use their own alternative inks to take up the responsibility of maintenance, otherwise the accessories will not be sold to users. In fact, if this kind of thing happens in other European countries, it will go to court soon.
It is understandable that the manufacturer is not responsible for the repair when the ink passes through the nozzle and the ink supply portion. However, other places such as motorcycles, paper exits, and electronic parts, where no ink passes, should be maintained. In fact, suppliers cannot refuse to provide certain maintenance services on the grounds of substitute ink. Recently, the new model of inkjet printers are equipped with an ink-protection recording device. When used up, be sure to insert a box of original ink or enter the password provided on the original ink to resume the nozzle. Nothing wrong, this kind of protection is for the manufacturer to ensure that the user chooses the original ink, but for the user, they have no optional rights.
To make an analogy, I bought a brand new car. Is it necessary to use the gasoline specified by the manufacturer before it can be maintained? Even if you use the gasoline they supply, can you drive the car? In this way, if the supplier can not provide gasoline, then the new car is not finished? By the same token, buying a new machine, maintenance is a promise, but also a responsibility, can not refuse to perform because they did not use their products, this barbaric behavior, it is worth the user to ponder.
Recently, I have received news that European manufacturers have requested that major inkjet printer manufacturers, when manufacturing new models, can no longer limit the use of other inks by "Microchip" or any form, and will be fully open before 2006. This also proves that the selection of alternative inks is not a crime. It should not be punished without maintenance. From another point of view, in order to retain customers, suppliers should take the positive attitude of the original ink and the substitute ink as much as possible to provide better and faster service, so that customers can understand the original benefits, instead of refusing to maintain or Set the level to force the customer to obey. In fact, in the mindset of the user, as long as the price of ink is reasonable, the quality is stable, and what is the difference between which company picks up the goods?
In a nutshell, there are many types of inks, quality and price will be mixed, as long as you choose properly, you can improve your competitiveness and reduce a lot of trouble. But the most important thing is that your own health, don't be greedy for a while, and sacrifice the most precious things.
