After printing, various post-processing steps are required to achieve the final eyeshadow palette packaging product we commonly see. These steps are collectively known as post-printing processes. Today, we’ll introduce some common post-printing techniques.

1. Varnishing

Varnishing and oiling are often mentioned together, but they are different processes. Varnishing involves applying a colorless, transparent coating (or spraying, printing) on the printed surface. After leveling, drying, polishing, and curing, a thin, even, transparent, glossy layer forms on the surface, enhancing smoothness and protecting printed images and text. This process includes several types such as coating varnishing, UV varnishing, and pearlescent varnishing.

2. Laminating

Also known as “over-lamination,” “plastic coating,” or “film lamination,” this process uses a laminating machine to cover the surface of the printed material with a transparent plastic film (0.012-0.02mm thick). This creates a composite product combining paper and plastic. Common laminating techniques include gloss laminating, matte laminating, UV gloss laminating, and PET laminating. This technique is widely used for book covers, brochures, cartons, paper boxes, stickers, and manuals.

3. Hot Stamping

Hot stamping involves heating a metal die and applying foil to print gold or silver text or patterns on the printed material, giving it a metallic texture and effect. With advancements in printing technology, there are now techniques like 3D hot stamping, also known as embossed hot stamping, which adds depth and texture to the design.

4. Embossing

Embossing, also known as debossing or embossing, uses pressure to create raised or recessed designs on the printed material. The process involves etching a metal plate to form a raised and a recessed plate that press together to create the design. There are two types: the more affordable standard etched plate and the more expensive laser-engraved plate.

5. Flocking and Glittering

To make the product look more high-end, some designs include flocking or glittering. Flocking involves applying a layer of glue on the surface and then adding flock material (tiny fibers) or glitter powder for a luxurious finish.

Conclusion

Understanding these post-printing processes is crucial for creating high-quality, visually appealing eyeshadow palette packaging. Each technique offers unique benefits and can significantly enhance the final product’s look and feel, helping it stand out in a competitive market.
