Application of UV Printing Ink on Film (4)
2024-04-01 01:06:21
When we formed a film (image) from the web graphic surface, we discovered that the presence of LJJTM enabled the molecules of the ink to be activated, and its printing film was significantly thinner than the ink of the same application, bright, smooth, uniform, anti-sticking, continuous The ink film not only increases the adhesion, but also greatly shortens the working hours, which is unmatched by other inks. In addition, in order to improve the low cost and high quality of non-absorbing UV offset polar materials, in addition to considering the printability and application range of UV inks, for example, the presence of oxygen in the air can also cure the light solid inks. There is a suppression effect, which leads to a decrease in surface dryness.
The role of additives in addition to the above mentioned, can also reduce the acidity, increase the softening point, reduce the conjugated double bond, grip high resistance to oxygen, make it difficult to adhere to the powder, low-temperature flow slow, promote packaging and printing graphics and presentation A variety of colors, low temperature stability, to meet the requirements of packaging and printing, with cheap, high-quality UV ink brand, participate in international market competition, to meet the challenges of the 21st century nano-ink technology era.
Fourth, test methods and conclusions 1. Check the balance of ink and water, use PH meter to measure the PH building separately, if the imbalance can use acetic acid or alkali for mediation. This article outlines.
2. Check whether the humidity and humidity of the military environment are controlled between 60±5% and 22±3°C.
3. Check that the original fountain solution is in contact with the lithographic plate, as far as possible without contact.
4. Check whether the binder is light, transparent, and the purity of the cyan agent.
5. Check the photo-setting time, whether it is instantaneously dry, as long as the activity is good, can appropriately extend the drying time of a monochrome is generally 15KW, four-color is generally 64KW to declare and lamp life.
6. Check the UV blocking property to see if it has abrasion resistance.
7 test adhesion, 1 circle method; 2 with the needle on the ink film marked × shape, and then affixed with an adhesive tape on the score, and pull, 0-10% off as qualified, otherwise, otherwise.
8. Check the speed of photo-setting; 1 No stickiness (if possible pressurization may cause dirtiness); 2 Thumb turbulence without sticking (downward pressure of about 5KG), use the finger to make a rotary motion on the ink film to 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, and stickiness the same as the lithographic ink.
10. Check the impact strength is the same as the printing of 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.
V. DISCUSSION AND DIFFICULTY DISCUSSION 1. The balance control of ink and ink can expand the scope of control in the use of acid timing to facilitate control in the offset printing process.
2. Control of Storage Period Whether or not a photo-spraying agent is added in a small amount before printing or ink-making, the printing is insufficient to increase the use period and reduce the waste of resources. (To be continued)
