What are the differences in the effects of different printing methods on copperplate paper adhesive labels?

There are significant differences in the effects of different printing methods on copperplate paper adhesive labels. The following is a detailed analysis of the effects of several common printing methods:

1. Ink printing (such as inkjet, laser, offset printing)

Effect: Ink printing can present high color reproduction and delicate printing effects, suitable for complex patterns and high-quality printing needs.

Application: Commonly used in fields that require exquisite printing, such as product labels, cosmetic packaging, food labels, etc.

Attention: When using ink printing, copperplate paper adhesive labels are prone to moisture and scratches if not coated with film. Therefore, it is recommended to apply film to enhance durability and waterproofing. Meanwhile, specialized printing equipment is required.

2. Thermal printing

Principle: Color development can be achieved by heating with a thermal printer without the need for ink.

Effect: The printing speed is fast, but it is prone to fading when exposed to light or heat for a long time. For example, receipts may become blurry after six months.

Application: Suitable for short-term use scenarios such as express waybills, supermarket receipts, medical labels, etc.

Environmental friendliness: Some thermal paper contains bisphenol A (BPA) and should be selected as BPA free and environmentally friendly; Meanwhile, thermal paper is not recyclable.

3. Hot stamping/silver stamping process

Principle: By using the principle of hot press transfer, the aluminum layer in the electroplated aluminum is transferred to the surface of the substrate, forming a special metallic effect.

Effect: Not only can it increase the surface decoration of adhesive labels, but it can also improve the anti-counterfeiting performance of products.

Application: Usually used for logos, labels, trademarks, etc., to enhance the added value of products.

Cost: The process is complex and the cost is high.

4. Die cutting and indentation process

Die cutting: Using a die cutting blade for die cutting, the shape of the printed product is no longer limited to straight or right angles, helping to shape the product.

Indentation: Pressing marks or leaving grooves for bending on adhesive paper to facilitate the use of adhesive.

Effect and application: Both of these processes can make self-adhesive labels more exquisite in appearance and better meet various usage needs, such as irregular labels, foldable labels, etc.

In summary, different printing methods have their own characteristics in the effect of copperplate paper adhesive labels, and the appropriate printing method should be selected according to specific needs and scenarios.
