In the realm of sticker printing, the term "white layer" refers to the application of a layer of white ink at the printing position before the actual content is printed onto the sticker. This strategic approach enhances visibility and addresses specific challenges associated with different materials.
Purpose of a White Layer:
The primary objective of incorporating a white layer is to optimize the visibility of printed content, especially when dealing with transparent materials. While content is typically clear on white surfaces, issues arise when transparent stickers are applied to dark-colored glass or plastic bottles. Directly printing on transparent material can result in a darker and less visible appearance of the content, negatively impacting the overall presentation of the product.
Imagine your product on a supermarket shelf – if the label content isn't clear, potential customers may lose patience in deciphering essential information about your product. In essence, the white layer serves to make printed content more noticeable. When customizing self-adhesive labels, it's crucial to specify the addition of a white layer. However, if you choose a white material for your label, the use of a white layer may not be necessary.
Instances Requiring a White Layer:
Apart from addressing visibility concerns on transparent materials against dark backgrounds, there are specific situations where a white layer is indispensable. Laser stickers, known for their waterproof, oil-resistant, and durable plastic material with a natural rainbow effect, may require a white layer. This is particularly relevant when wanting specific parts of the sticker to display without the laser effect, ensuring a customized appearance.
Similarly, adhesive silver BOPP (biaxially oriented polypropylene) material stickers, composed of a waterproof, oil-resistant, and durable plastic material that naturally exhibits a silver metallic effect, may require a white coating. The choice to include a white layer depends on whether you seek optimal visibility for the printed part or if a distinct metallic effect is the desired outcome.
In summary, the utilization of white layers in sticker printing is a strategic choice to enhance visibility and address specific challenges associated with different materials. Whether dealing with transparent materials, laser stickers, or adhesive silver BOPP, understanding the role of white layers ensures optimal customization and a visually appealing final product.
