Improved UV-curable imitation metal etching ink features

Imitation metal etching ink is a kind of single component UV light curing ink, commonly known as "smoothing ink", because its printed products have obvious etching effect, ink film is full, three-dimensional sense is strong, so that the packaged products are full of high-grade, It has been widely used in the color printing industry for cigarette labels, wine labels, cosmetics, and health products. Compared to traditional solvent inks, it has the following advantages:

1. Printed products are exquisite and three-dimensional fullness;
2. No solvent, high solid content, less environmental pollution;
3. Fast curing, energy-saving space, high production efficiency;
4. Ink film is resistant to friction, solvent and heat.

However, with the continuous development of the packaging and printing industry, this common type of imitation metal etching ink has been unable to meet the requirements of product packaging in some aspects, there are some problems that need to be solved, such as:

1. It has strong irritation to human skin, and after contact with the skin, it produces allergies and other symptoms. The printing worker is vulnerable to injury.

2. It has an unpleasant odor and pollutes the working environment of the printing shop. The odor remaining on the printed matter will affect the quality of the packaged product, and it is not suitable for the printing of articles such as cigarettes, tea leaves and the like that are highly odor absorbent.

3. In the case of printed products that require post-processing such as embossing, die-cutting, etc., the ink layer is explosive and has insufficient fastness. At present, some improved imitation metal etching inks have been successfully developed and put into the market to meet the needs of customers, and are welcomed by packaging and printing plants.

The types and characteristics of improved products:

1. Odorless and environmentally friendly (SY-DH, SY-GH, SY-WH) does not contain any ingredients with unpleasant odor. The printing process and printed products are odorless, and there is no pollution to the printing shop environment. It is extremely suitable for packaging and printing of taboo products such as cigarettes, tea, health products, and cosmetics.

2. The non-stimulating and safe type (SY-DA, SY-GA, SY-WA) does not cause any irritation to the human skin, avoiding allergies or burns caused by the operator's careless contact with the skin, and ensuring the safety of the operator.

3. High adhesion scratch resistance type (SY-DT, SY-GT, SY-WT) has excellent adhesion fastness and surface hardness to paper substrates, especially general-purpose gold and silver cardboard, and print products are scratch-resistant Scratch resistance is good.

4. Highly flexible and impact resistant (SY-DP, SY-GP, SY-WP) Ink layer cured ink film has excellent flexibility, can pass through convex, die-cut and other impact of the back The machining process eliminates the need for a special layout for avoiding the molded part, and also solves the problem of printing of a molded part pattern that cannot be specially designed.

Improved product use features:

For the above-mentioned improved varieties, the products provided by the ink factory are common products for various printing factories, and they can also provide special specifications for products upon request from customers. These products can be used under the same conditions as the ordinary type of metal etching inks, ie screen printing, printing, and curing conditions are all unique. Under normal circumstances, the product can be used directly, but if the weather temperature or humidity changes greatly, the necessary viscosity or dry speed adjustment should be made before printing. If adjustment is required, special thinners provided by the ink factory must be used in combination with the corresponding brands. Otherwise, it will affect the use of this improved product and the printing effect.
