Packaging label printing 'ink' affect the quality of the product how to do?

In the process of packaging label printing, surface printing ink of problems easily, largely affect the quality of printed matter, and even delay the delivery date. Here, professional manufacturer of flexible packaging packaging from tension, dry ink, ink and material matching three aspects to summarize and list of common ink ink reasons and improving methods. One, the influence of tension on the ink and the solution for printing surface corona treatment to thin film materials, to achieve remarkable ink wetting, dyne value generally demand more than 38 mm/m, less than 36 mm/m a brief drop ink problems; Together, the material of dyne value will fade over time, off the ink printing problems. The problem is the essence of tension. Solution: 1, the function with online corona satellite rotary press, online corona processing to enhance the surface membrane materials can be; 2, choose intermittent printing presses to render coating surface treatment, to enhance surface printing adhesion; 3, when the dyne value appear fade, when printing with corona processing demand, but the size of the dyne value cannot fully represent the adhesion between the oil and the surface material, general dyne value fade cycle for 3 months - 6 months, it is recommended to minimize inventory material stored for a long time. 5, it is recommended to use higher type of ink adhesion, recommend to the ink supplier. Second, the ink is monotonous and the effect of tension on the ink and the solution in printing process, ink drying and tension can also cause a drop of ink. Specific include: printing ink layer too thick the drab incomplete; UV lamp energy shortage of lamp aging, lamp aging reflectors, lead to the UV lamp drab inadequate curing, ink layer drying; Excessive and dry ink, resulting in material deformation, resulting in ink layer fall off. Solution: 1, choose deep thin printing ink, is commonly known as the decrease of ink, such as the color ink, can match the deep, in some less formal printing ink, arrived in the sample effect, increasing the UV lamp output power, printing speed, increase the UV lamp irradiation time, arrived in monotone function. This plan is applicable to old intermittent perhaps satellite rotary machine and UV lamp processing plan. 2, check to see if the UV lamp aging and clean reflectors. Domestic UV lamp use full 500 - commonly Lamp life spans 1000-1000 hours, imports 2500 hours, the condition of concrete can be refer to practice using. Suggest YinChang every half a year or so a UV lamp cleaning operations, ensure the normal use. 3, drop the UV lamp power output, specific operation for the general YinChang templates, color sequence before several groups of color mostly corporate emblem may be small, the required lighting co. , LTD. , can open worth UV light, according to dry, no senior excessive exposure to the sun, because of the thin film materials absorb heat energy is limited, excessive exposure would amount to a membrane type winding deformation and brittle materials, printing ink adhesion drop etc, can follow after the first low grade senior applying principles UV lamp. Three ink, ink and material matching is opposite the influence and solution, after all, ink and material matching degree will inevitably trigger off the ink. Using the ink molecules, for example, tension is too large, cannot be in substrates materials constitute uniform ink layer surface; Or use across the shelf life of the ink type or low-quality homebred brand inks, would constitute a printing ink. Treatment plan: 1, can switch to match the printability of printing ink, such as membrane class special inks and fast and light fastness printing ink; 2, in view of the overdue ink, it will be subject to conditions in printing before you do inspection, maybe some brief text printing maybe small corporate emblem images, and some products are lower level; 3, printing large field image and full version of the network cable, good recommendations apply brand, high adhesion function of ink.
