Which printing method is suitable for BOPP color synthetic paper?

For BOPP color synthetic paper, the suitable printing method mainly depends on the required printing effect, environmental requirements and cost considerations. The following are some common printing methods and their applicability analysis:

1. Gravure printing

Applicability: Gravure printing is one of the most commonly used printing methods for BOPP films, because it can produce a thicker ink layer, a bright color, and can be inprinted to protect the ink layer. For BOPP color synthetic paper, intaglio printing can also provide good printing results, especially for those applications that require high color saturation and detail.

Advantages: bright color, thick ink layer, lasting printing effect.

Disadvantages: gravure printing has relatively large environmental pollution, and the use of ink and solvents may cause harm to the human body and the environment. In addition, the investment and maintenance costs of gravure printing equipment are also relatively high.

2. Flexographic printing

Suitability: Flexographic printing is an environmentally friendly printing method, suitable for printing a variety of materials. For BOPP color synthetic paper, flexographic printing can provide good printing quality while meeting environmental requirements. With the continuous progress of flexographic printing technology, its printing effect is also improving, and it is getting closer to the effect of intaglio printing.

Advantages: Environmental protection, light printing pressure, little damage to the material, relatively low cost.

Disadvantages: Compared with intaglio printing, flexo printing may have a slightly inferior printing effect in some aspects, especially in color saturation and detail expression.

3. Offset printing (lithography)

Applicability: Offset printing is a kind of lithographic printing, suitable for prints with high color quality requirements. For BOPP color synthetic paper, if the print has high requirements for color reproduction and fineness, offset printing is a good choice. However, it should be noted that offset printing has higher requirements for the surface smoothness of the substrate.

Advantages: high color reproduction, high printing accuracy, suitable for mass printing.

Disadvantages: High requirements for the surface smoothness of the substrate may require pretreatment; The cost is relatively high (especially in plate making).

4. Screen printing

Applicability: Screen printing is suitable for printing of various irregular shapes and special materials. For special effects printing on BOPP color synthetic paper (such as local glazing, gilding, etc.), screen printing may be a suitable choice. However, it should be noted that the printing speed of screen printing is relatively slow, and it is not suitable for mass printing.

Advantages: Unique printing effect, suitable for special materials and shapes.

Disadvantages: slow printing speed, not suitable for mass printing; Costs may vary depending on plate and ink.

5. Digital printing

Applicability: Digital printing is a flexible and efficient way of printing, suitable for small batch, personalized printing needs. For short printing on BOPP color synthetic paper or personalized custom prints, digital printing may be a good option.

Advantages: Flexible and efficient, no plate making, instant error correction, variable printing.

Disadvantages: relatively high cost (especially for mass prints); In some aspects may not be able to completely replace the traditional printing effect.

In summary, the choice of printing method for BOPP color synthetic paper should be decided according to the specific printing needs, environmental requirements and cost considerations. In most cases, intaglio printing and flexographic printing are the more common choices; For special effects printing or small batch personalized printing needs, you can consider screen printing or digital printing.
