Printing process of stickers: art of color, control of details

introduction

Stickers, as a widely used item in advertising, decoration, signage and other fields, have a direct impact on the quality and visual effect of the product through their printing process. This article will take you to a detailed understanding of the printing process of stickers, explore the art of color and the control of details.

1、 Raw materials for sticker printing

1. Substrate
There are various types of substrates for stickers, including paper, plastic, film, etc. The choice of suitable substrate depends on the usage environment and application scenario of the sticker.

2. Ink
Ink is a key material for sticker printing, and its performance directly affects the printing effect and the durability of stickers. Common inks include water-based ink, solvent ink, ultraviolet ink, etc.

3. Printing adhesive
Printing adhesive is used for bonding stickers, requiring good adhesion and durability.

2、 The process flow of sticker printing

1. Pre press design
Designers design stickers based on customer needs, including patterns, text, colors, etc. After the design is completed, perform color separation processing to determine the printing color.

2. Printing
According to the design requirements, choose the appropriate printing process, which commonly includes the following:

-Screen printing: suitable for large-scale production, suitable for printing complex patterns and spot colors.
-Offset printing: suitable for printing large amounts of text and simple patterns, with low cost.
-Flexographic printing: suitable for medium and small batch production, with high printing quality and suitable for a variety of substrates.
-Digital printing: suitable for small batches, personalized customization, fast printing speed, and low cost.

3. Post processing
-Adhesive: Adhere the printed stickers to the printing adhesive to ensure the adhesive strength of the stickers.
-Cutting: Cut the stickers according to design requirements to ensure accurate size.
-Surface treatment: If necessary, special treatment can be applied to the surface of the sticker, such as lamination, sanding, etc.

3、 The key technology of sticker printing

1. Color separation and color matching
Color separation is the process of dividing design patterns into printed colors, while color matching ensures that each color pattern is accurately aligned in the same position.

2. Ink blending
According to the substrate and printing requirements, mix the appropriate ink to ensure the printing effect.

3. Printing pressure and speed
The printing pressure and speed directly affect the printing quality and efficiency, and need to be adjusted according to the actual situation.

4. Surface treatment technology
Surface treatment techniques such as lamination and sanding can enhance the durability and aesthetics of stickers.

4、 Conclusion

The printing process of stickers is a skill that combines color art and detail control. From the selection of raw materials to printing and post-processing, every step is crucial. With the continuous advancement of printing technology, the printing process of stickers will become more exquisite, bringing more high-quality and personalized products to the market.
