To deal with the Barcode Sticker Label printing ink, then teach you three essential skills

To deal with the Barcode Sticker Label printing "ink", then teach you three essential skills!

The influence of tension on inking and the solution

For the printing surface of corona treated film materials, to achieve good ink wetting, the dyne value usually needs more than 38mm/m, lower than 36mm/m is prone to ink loss problem; At the same time, the dyne value of this material will gradually fade over time, resulting in ink loss. The essence of this problem is one of tension.

Solution:

1. Improve the surface energy of membrane materials by on-line corona processing using the satellite rotary machine with on-line corona function;

2. Intermittent printing machine can be used for surface primer coating to improve the adhesion of surface printing;

3, when the dyne value appears to fade, the printing needs to be treated with corona, but the size of the dyne value can not fully represent the oil.

4, adhesion between the surface material, the general dyne value of the fade cycle of 3 months to 6 months, so it is recommended to reduce the long-term storage of raw materials inventory.

5, recommend the use of higher adhesion ink, ink suppliers are recommended to consult.

Ink drying and tension on the impact of ink and solutions

In the Barcode Sticker Label printing process, ink drying and tension can also cause ink loss. Specifically divided into: printing ink layer is too thick resulting in incomplete drying; UV lamp energy is insufficient lamp aging, lamp reflective cover aging, resulting in UV lamp drying curing is not sufficient, the ink layer is not dry; Excessive drying ink, resulting in material deformation, the formation of ink layer off.

Solution:

1, the use of deep ink thin printing, is commonly known as reducing the amount of ink, such as spot color ground ink, can match the depth of some, in the formal printing ink is small, to achieve the effect of proofs, at the same time increase the output power of UV lamp, reduce the printing speed, increase the UV lamp irradiation time, to achieve the drying effect. This solution is suitable for old intermittent or satellite rotating machines and old UV lamp solutions.

2, check whether the UV lamp is aging, and clean the reflective cover. Usually domestic UV lamp life of 500-1000 hours or so, imported lamp life of 1000-2500 hours or so, specific can refer to the actual use of the situation. It is recommended that printing plants clean UV lamps every half a year or so to ensure normal use.

3, to reduce the UV lamp power output, specific operation for the general YinChang templates, former sets of color series color mostly corporate emblem or the fine print, the required lighting co., LTD., can open worth UV light, according to dry, not excessive exposure to the sun, because of the thin film material to absorb heat energy is limited, excessive exposure can cause crimped brittle membrane materials, printing ink adhesion slower, Can follow the first low grade after high-grade UV lamp use principle.

Ink and material matching on the impact of inking and solutions

Finally, the matching degree of ink and material will also cause inking to a certain extent. For example, the use of ink molecular tension is too large, can not form a uniform ink layer on the substrate material surface; Or use more than the shelf life of ink models or inferior domestic brand ink, will cause printing ink.

Solution:

1, can be switched to match the Barcode Sticker Label printing material ink, such as film special ink and light fastness and light fastness ink;

2, for expired ink, it is necessary to do printing test before printing, or printing some simple words or small logo pattern, and some low-end products;

3, printing a large area of field and full screen network line pattern, recommend the use of good brand, high adhesion performance ink.
