Adaptive And Hot Stamping Foil Stamping To Improve The Quality - Hot Stamping, Hot Stamping Foil -

Adaptive refers to the so-called hot stamping foil stamping model selection and speed

, temperature, pressure and other factors matched. Equipment and other hardware in the fixed case, the right adaptive control to improve the stamping stamping the most important means of quality. Following on from the practice reflected in the number of quality problems for an analysis in order to facilitate scientific adaptive control gilt.

1, stamping or hot stamping is not false

The surface characteristics of the printed, foil of the nature of the stamping pressure, temperature, and a variety of factors.

Printed surface Dusting Withdrawal of viscosity or surface containing too much, like the light syrup Additive This will prevent the adsorption of foil and paper. The solution: surface to powder processing or Print Process solution. Direct impact on the improper selection of hot stamping foil fastness. Tipping area should be based on the size of stamping material properties are taken into account what type of foil used. Is mainly made of anodized aluminum Shanghai Shen Yong Gilt Limited production of the Peacock brand, import hot stamping foil mainly Germany Kurtz's PM and LK series, Japan's A, K, H Series, South Korea KOLON the SP series. According to our practice and testing, matching foil can refer to the following main categories: ordinary hot stamping foil products have 88? L type, KURZ the PM-type; tobacco, cosmetics, color the edges of printed matter (including the Indian gold, silver and India ) of hot stamping foil 88? 2; , cosmetics Package The foil stamping and other fine handwriting 88? 3,88? 4, PM288, etc.; apply to OPP or PET lamination of paper and paperboard with UV inks, hot stamping foil coating products have 88 worksheets? 4 type, K Series, LK series, and the SP series. Not correctly grasp the hot stamping equipment and stamping press time and temperature match between the impact stamping fastness and clarity of graphic profile. As the equipment was different stamping materials, hot pressing time, stamping temperature are not the same. For example, high-speed rotary speed of the fast line contact imprint, stamping temperature higher than the round would flatten or flatten. In general, rotary hot stamping temperature of 190 ~ 220 , round flattened about 130 ~ 150 , flatten to about 100 ~ 120 . Of course, the hot pressing time, temperature and production efficiency stamping a great extent constrained by the foil transfer performance.

2, anti-La After the Pull is hot stamping foil to the printing ink or printing documents Varnish And so, away. This is mainly due to the surface of printing ink was dry on the surface of UV such as India or post-processed properly, causing the surface of printing ink, UV oil combined with the paper surface caused by unsound. Solution: When printing products drying after tipping. Also you can use foil, lower separation, heat metastatic excellent foil.

3, after the foil stamping paste version and color paste version, mainly due to poor production of stamping edition, anodized aluminum foil installation may relax or go foil the incorrect result. After stamping foil stamping color is mainly caused by high temperature. In addition, foil stamping fight wrinkles too easily lead to stack color unevenness and discoloration, reduce the temperature by an appropriate solution. For the circle Pressing Machine Type can be sent to foil Department install a fan to keep pulling foil floating Ting, avoid touching hot stamping foil stamping before the version and burned.

4, technology arrangements wrong, damaged foil surface gloss, graphic profile send virtual. Film processing requires tipping, people often worry that easily wipe off the first gold foil stamping and then coating it easy to create:

film (especially matt film) will destroy the luster of the surface of anodized aluminum, not coated with water-soluble glue, otherwise it will create black anodized aluminum surface, and very likely to stick in the Graphic Edge powder made virtual phenomenon caused .

After stamping and depression because of pressure, together with glue easily penetrate the surface of anodized aluminum, easy to cause bronzing Department OPP and paper separation affect product quality. The correct process is to be coated first and then tipping, selection and matching foil OPP.
