Only by seizing the commanding heights of science and technology can we expand the space for printing and consumption of non-polar flexible packaging printing media; only by occupying a beachhead in the market economy can we emphasize repeatedly that time is money and quality is life; only based on high-quality, low-value printing inks, Only by grasping the opportunity to occupy the beachhead of the market economy, can we use the latest market information feedback to capture the latest scientific and technological achievements at home and abroad for my own use.

Testing method

1. Check the balance of ink and ink, and measure the pH of the ink with an acid meter. If the imbalance, use acetic acid or alkali for mediation. This article outlines.

2. Whether the humidity and humidity of the military environment is controlled between 60±5% and 22±3°C.

3. Check if the original fountain solution is in contact with the lithographic plate. Do not touch as much as possible.

4. Check whether the link material is light, transparent, and the purity of the cyan agent.

5, inspection of light-setting time, whether it is instantaneous drying, as long as the activity is good, can be appropriately extended drying time a monochrome is generally 15KW, four-color general is 64KW to declare and lamp life.

6. Check the UV blocking property to see if it has abrasion resistance.

7, test adhesion. 1 circle the law; 2 with the needle on the ink film on the x-shaped, and then affixed with adhesive tape on the nick, and pull, 0-10% off as qualified, otherwise, otherwise.

8, check the photo-solid speed; 1 non-sticky (such as pressurization may be dirty); 2 thumb turbulence no stick (about 5KG down pressure), with the finger on the ink film for rotational turbulence to the ink film No breakage, visible curing through; 3 no scratch curing, including the use of nails to fight the ink film is not broken, visible curing completely.

9, test the color, fineness, fluidity, coloring, sticky and lithographic ink the same.

10. The test impact strength is the same as that of printed iron.

Explanation: Through experiments, trials, tests, and analysis, it is believed that the recipes of 6# and 7# are feasible. Because the materials in the 6# formula are all market prices, and the UV ink domestic market is about 220,000 yuan, and the gross profit is almost 1000%. Subtract material consumption and utilities, and the profit can reach 500%.

If you add live LJJ·TM additives by commercial ink, you can save about 5% cost per kilogram of ink. After adding tons of additives, you can save more than 1,000 yuan per ton of ink.

Secondly, in commercially available UV inks, the use of compounding technology, in view of the long-term point of view, eliminates the need for direct back brushing of PVC electrostatic film, and makes up for the insufficiency of existing UV inks using lithographic printing on non-polar materials. With the nano-Zhu ink chemical technology as a major hot spot in the industry.

Still doubtful and difficult

1. The balance control of ink and ink can expand the scope of control in the use of acidity timing to facilitate control in the offset printing process.

2. Control of Storage Period Whether a light scattering agent is added in a small amount before printing or ink printing, the printing is insufficient to increase the use period and reduce the waste of resources.

3. Control of Photon Decomposition In addition to adding the LJJTMTM method, whether to promote or improve the new ink-making method without photoinitiator is widely used.

4, the hue of UV ink positioning a country can formulate a unified UV ink colorant quality standards, especially the purity index. If you can solve the problem of poor tone and printers to use a fully automatic color matching system instrument, you can achieve the standard and shorten the production cycle.

5, the high cost of UV inks. Whether high prices can be reduced from the formula and process to the general offset ink price, while improving from the hydrogen bond, tension, free energy and other aspects, to improve the attachment fastness, simplify the process and reduce the ozone odor, thereby reducing environmental pollution and increase the print bit.

6, non-absorbing UV offset non-polar materials, how to increase from the current 5-8 thousand in India / h, to 30,000 in India / h, while allowing the text is not dissolved in the solvent, aluminum metal PS version costs, the use of The replacement of new, thinner, high-efficiency polymers becomes a reality.

7, how to easily remove UV ink printing ink film, easy recycling, regeneration and reuse.

8, the rigid problem of printing color sequence, how can be like other ink, the color sequence can be freely controlled, no irritating to the skin, as well as reducing the number of printing plate, ink guide, transfer roller.

The advent of non-absorbable UV offset non-polar inks, in order to dominate the trend, requires the packaging and printing industry in China to establish a crisis awareness of the national brand, in the development of inheritance, innovation in the inheritance, in order to compete in the spirit of the moment, With joint exploration and hard work, the spring sunshine will not be far off.
