- Film covering
As the name suggests, it is to add a layer of protective film to the printing paper, which can be waterproof, protect the printing effect, and reduce damage to the material. Especially in custom jewelry box packaging with high printing requirements, it is more commonly used. Generally, lamination is only applied on coated paper, and only by laminating on coated paper can it be tightly adhered to the paper. If laminating on non coated paper, many fine bubbles will be generated, and the coated film will be easily peeled off.
- OveroilOil coating is mainly used to protect the printing effect. Both coated and uncoated paper can be oil coated. By applying a layer of oil on the surface paper, the printed color will not fade so easily, and the cost of oil coating will be cheaper than that of lamination. For coated paper, it is usually necessary to protect the printing effect, and for lower price situations, oil coating will be chosen; Or products that are not suitable for laminating, such as folding, brochure pages, envelopes, etc., may choose to use oil to protect the printing effect; There is also non coated paper that cannot be glued, so oil can only be chosen to protect the printing effect. Usually, when custom jewelry box paper packaging with white cow, we use oil protection to ensure good printing effect and prevent color fading.
- Spot UVThe process of UV printing, also known as silk screen printing, can be performed on any paper. However, if the texture is deep, the UV effect may be slightly lacking. Additionally, UV presents a bright surface effect, so UV treatment is generally not added on top of photoresist. Custom jewelry paper box packaging will highlight important parts, such as brand logos.
- Hot foil stamping: Golden/Silver
Hot stamping process: Similar to UV technology, it is to highlight the uniqueness of the brand when custom jewelry paper packaging box. Make an electric plate (also known as a mold), which is carved according to the customer's requirements. After heating the electric plate, the gold material (which can have many different colors collectively referred to as gold material) is pressed onto the paper. High temperature and high pressure can make the gold material hot stamping on the paper according to the shape we need, Or on other fabrics (such as fabric, leather, PVC, etc.), the hot stamping materials used for each different material are different and cannot be mixed.
The process of embossing/embossing is similar to that of hot stamping, in that both require the preparation of an electrical board and the application of high pressure to press the desired pattern onto the surface of the paper, creating a raised or recessed pattern. Convex/concave stimulation does not require heating or metal support. This sudden change is more difficult than UV and hot stamping to highlight the logo part of the custom jewelry packaging box, because whether it is convex or concave, in addition to visual impact, there are also layers in the hand feel, which will leave a particularly deep impression on people.
