After years of development, China has become an inkjet printing consumables recycling industry, and the brand is compatible with the consumables industry. The large scale of development and production in the Pearl River Delta region and the Yangtze River Delta Region has a certain influence in the world.
Although the output is very large, after the market tests the actual technical tests, the technical parameters of most of the products are still unsatisfactory, and there is a big gap between the products of the original manufacturers. The most critical parameters: the acid-base stability at room temperature; the storage time at room temperature; the effect of storage chemicals at room temperature on the color curve of the ink dye monomer; the bacterial product of the ink during normal storage; The maximum standby time; the effect of high saturation ink on the print head; the effect of the color change curve on the output quality of the same lot of ink within a certain time limit; the harmful volatiles of the synthetic ink;
Change in pH at room temperature is a core hard indicator. In the past, the original factory ink was stored at room temperature for 3 years. Now that most users in China use compatible inks, the quality of the ink is not good, and the ink storage index is set at 1 year. The chemical stability of most ink cartridges has been measured for less than one year. Some brands of ink cartridges that are very loud in advertisements have not reached ink for half a year, and their pH has dropped from 7.8 to about 3-4. They cannot be used. Because China's advertising users blindly pursue the low price of ink, which led to the low price and low quality of all ink. The result of the low price and low quality is that the manufacturer does not have surplus profits to carry out the technical improvement of the product series. Including foreign original manufacturers have reduced the quality standards for products entering our country. It can now be seen that the standard for the positioning of original consumables on the market has been reduced to one year, such a time limit. This situation hurts himself.
Some brand inks performed well when they were first used, but soon after, there were products or deposits in the continuous ink supply pipeline. One problem is that bacteria have arrived, and the other is the high salt content of dyes. In particular, some inks are blindly pursuing high color saturation, and the proportion of dyes is too large to cause supersaturated precipitation. The problem with most inks is that the technicians only understand chemistry, do not understand the mistakes made by the relevant physical and physics and chemistry disciplines, and the acidity of ph is constantly being acidified. Bacterial products are examples and the basic formula of ink is not perfect. Many problems.
Although the original manufacturer of each batch of ink can not do the same color error, but after all, with the naked eye can not see it. Compatible ink production cannot have original conditions and it is impossible to get the same type of dye. However, as long as it has its own production formula and strict process, color balance is very easy to do. To be exactly the same with the original manufacturer ink color, it is impossible, because the original manufacturer's ink dye is a professional development, special supply, compatible supplies manufacturers can not buy in the market. As far as I know, the compatible inks that are currently on the market, and the dyes used by various manufacturers are various. The use of imported salt-free dyes with better quality is expensive, but the light fastness is generally not good. Some manufacturers use imported low-salt dyes in order to lower prices. The price of this type of dye is not much lower than that without salt, but the light fastness can be better than that without salt, but if the amount is not well controlled during use, it will cause serious dye aggregation and sedimentation in the ink, blocking the inking pipeline. . Other manufacturers use domestic dyes, which have obvious price advantages and require good formula control. The main problems are poor stability, high salt content, prone to crystallization, and damage to the spray head.
After our experiments, the above situations are not absolute, and the salt-free and low-salt dyes and related shaded dyes can be cross-matched and complementary to each other, and high quality inks can be made.
Here I would like to mention the relevant indicators of harmful volatiles. Although RoSH detection specifications for ink chemicals are stipulated, it is a static test for the presence of hazardous substances in the ink chemical composition. However, inkjet inks are used under dynamic conditions. When they are static, the chemical substances of the ink can pass the detection as long as they contain no harmful substances. However, in the dynamic state, when the ink ink dots fly out and the organic matter volatilizes, there is no over-determined indicator of whether the gas swirling in the air will harm people. There is a lot of ink in the country, which produces a strong odor in use. I have done experiments. Although there is no acute toxicity to people, this kind of gas causes allergic constitution people to induce allergens. The other is the possibility of prolonged stimulation of the respiratory system by the user's respiratory system. Some inks have no taste at rest, but after printing, the odors produced on the coating with inkjet paper cannot be dispersed for a long time. The printed picture, if hung indoors, may have adverse effects on the indoor air.
At present, domestic users have begun to increase the quality requirements of consumables, especially with the improvement of living standards, there are a large number of hobby photographers to join, and promote product development in this industry. The ink used for the image output is not the resolution level of the 4 colors in the past. Requires ink to work synchronously with more than 6 colors at high speed and high frequency to display accurately. Compatible inks are also required to be easily adjustable in the color management mode. Color reproduction requires little error. In the 8-bit color output management required for the image output, the 16-level grayscale performance of each color can be seen with the naked eye. The photos printed by the ink in the past cannot have the quality of the photos currently output due to the difference in the matching of ink colors.
At present, we see the domestic ink, whether it is produced in the Yangtze River Delta or the Pearl River Delta region, its main formula structure is the result of physical and chemical testing of the original ink. Here I want to re-explain (originally published in the printing supplies industry internal publications have expressed opinions), ink-jet printing inks, not using a few chemical and physical testing equipment, a simple analysis, you can get a perfect chemical structure formula and technology. The core of inkjet inkjet printing equipment is a chemical and physical process complex ink. It is not a common ink in a constant sense, but a product produced by a comprehensive high-tech application control.
We displayed through the exchange of domestic and international conferences and took out our image ink of the “Pirago†brand in Xi’an. The most important core of this is the ability to use the HP nozzle for long life in HP thermal inkjet printing. This technical indicator is to compare the original factory with its ink, it is not necessarily better than this ink. This is where we are most confident now. This is also the result of comparing the use of ink with the original ink in actual use by users of the HP130 inkjet printer.
Xi'an Pigeon Ink also performed well in the long-range panorama. The general ink prints a few meters or less than a few meters will appear missing line breaks, pull the road appear in the output of the fatal flaws, and Perige ink can be perfect output full width 610mm frame eight meters long, the longest output 15 meters. On the HPZ2100 inkjet printer, a 1.07-meter long picture is output, which can be 8-12 meters at a time, and the picture is flawless. There is no comparable compatible ink in the image-level output. Now we use our ink for large studio users and large advertising users (hp:130/5000/5500/Z2100). We don't need to replace the nozzles in one year, which will greatly save the cost.
In the domestic conversion of the desktop machine with the supply system for the consumer, using our ink for the HP desktop integrated ink cartridges for conversion, the original can not use a few times the ink cartridge, now after using our ink, in two or three years does not need to replace the ink cartridges , And there are few faults.
All these prove that the ink quality has the greatest impact on the print head. If you want to use a good inkjet printer, you must have good ink. To produce a good photo, you need a good level of ink. To reduce costs, the most fundamental condition is also the need for a good ink. Compatible ink consumables, like other industrial products, require a strict quality standard system and strict production technology conditions. As long as there is a strict technical standard system support, the quality of compatible products will be greatly improved.
