How does the thickness of BOPP synthetic label paper affect the printing effect?

The thickness of BOPP (Biaxially Oriented Polypropylene) synthetic label paper has a significant impact on the printing effect. The following is a detailed analysis of the relationship between the thickness of BOPP synthetic label paper and printing effect:

1、 The Influence of Thickness on Printing Quality

Ink absorption and diffusion:

Thin BOPP synthetic label paper has relatively strong ink absorption and diffusion capabilities. This means that during the printing process, ink can more easily penetrate into the interior of the paper, potentially producing brighter and fuller color effects. However, thin paper can also cause excessive ink diffusion, resulting in blurry images or unclear text.

Thicker BOPP synthetic label paper has relatively weaker ink absorption and diffusion capabilities. This may lead to a decrease in the adhesion of ink on the surface of the paper, thereby affecting the clarity and color saturation of printing. But thick paper can also provide better load-bearing capacity and durability, reducing damage to printed content caused by friction or scratching.

Printing resolution:

The thickness of the paper can affect the contact pressure of the print head and the accuracy of ink ejection. Thinner paper may be more susceptible to the pressure of the print head during the printing process, resulting in uneven contact between the print head and the paper, thereby affecting the printing resolution.

Thicker paper can better withstand the pressure of the print head and reduce printing problems caused by uneven pressure. This helps maintain the stability and consistency of printing resolution.

2、 The specific performance of thickness on printing effect

Color Brightness: As mentioned above, thinner BOPP synthetic label paper may produce a more vibrant color effect, but it may also result in colors that are too heavy or blurry. Thicker paper may produce relatively lighter color effects, but the color saturation is more stable.

Clarity and Detail: Thicker BOPP synthetic label paper can better maintain clarity and detail performance during the printing process, as thick paper can better withstand the pressure of the print head and the jet force of ink. Thinner paper may cause blurring or loss of details during the printing process.

Durability: Thicker BOPP synthetic label paper typically has better durability and wear resistance. This means that when used outdoors or in harsh environments, thick paper can better maintain the integrity and readability of printed content. Thinner paper may be more susceptible to wear and tear or damage.

3、 Choose Suggestions

When choosing the thickness of BOPP synthetic label paper, consideration should be given to specific application scenarios and requirements. For example, in applications that require high clarity, vivid colors, and detailed expression, thicker paper can be chosen; In applications that require fast printing, low cost, or portability, thinner paper can be chosen. Meanwhile, attention should also be paid to the influence of factors such as paper material, coating, and adhesive on the printing effect.

In summary, the thickness of BOPP synthetic label paper has a significant impact on the printing effect. When choosing paper thickness, factors such as application scenarios, print quality, durability, and cost should be comprehensively considered to achieve the best printing effect and cost-effectiveness.
