Professional Custom Stickers Printing Manufacturer Since 2005
As a printing factory that has been dedicated to printing for 20 years, we have encountered many customers who want customized labels with unique texture but do not know what kind of process to choose. The hot stamping process has already been explained to everyone. You can find our previous news articles. Today, I will introduce to you what UV raised printing is and its applications.
Overview of V-convex oil printing
UV relief printing is a special printing technology that combines UV curing technology with the characteristics of relief printing. It can create a raised effect on the surface of printed materials, increasing their three-dimensional and tactile feel. This technology is widely used in packaging, labeling, decoration and other fields, especially in situations where brand image needs to be highlighted and product added value needs to be enhanced.
Characteristics of UV convex oil printing
Strong stereoscopic effect: UV convex oil printing can form a significant convex effect on the surface of printed materials, making the printed pattern have a strong sense of three dimensionality and three-dimensional effect.
High glossiness: UV cured ink has high glossiness, and the cured ink layer is not only bright, but also wear-resistant and durable, improving the texture and durability of printed products.
Environmental friendliness: UV curable ink is a solvent-free ink that does not undergo natural evaporation, avoiding the emission of harmful volatile substances and meeting modern environmental requirements.
Application of UV Convex Oil Printing
UV convex oil printing is widely used in the production of various printed materials due to its unique visual and tactile effects, including but not limited to:
Packaging: such as food packaging, cosmetics packaging, etc., can enhance the beauty and anti-counterfeiting function of packaging through UV convex oil printing.
Label: In label printing, UV convex oil printing can improve the recognition and grade of the label.
Decorations: such as greeting cards, invitations, etc., UV embossed printing can make these items more exquisite and high-end.
The process flow of UV convex oil printing
Printing: UV ink is used for printing, usually using screen printing to ensure that the ink can evenly cover the surface of the substrate.
Curing: After printing is completed, the ink is instantly cured by a UV curing machine. The ultraviolet rays emitted by the UV curing machine will quickly solidify the ink, forming a hard ink layer.
Post processing: Depending on the needs, some post-processing steps may also be performed, such as grinding, polishing, etc., to further enhance the texture of the printed material.
Precautions
When performing UV convex oil printing, the following aspects should be noted:
The selection of substrates: Different substrates have different absorption and adhesion to UV ink, and choosing the appropriate substrate is crucial.
Ink blending: Depending on specific printing requirements, it may be necessary to properly blend UV ink to achieve the desired printing effect.
Equipment maintenance: Regular inspection and maintenance of the UV curing machine to ensure its normal operation is crucial for ensuring printing quality.
In summary, UV relief printing is an advanced printing technology that combines UV curing technology and relief printing characteristics. It can bring unique three-dimensional effects and high glossiness to printed products, and is widely used in various fields. In practical operation, attention should be paid to the selection of substrates, ink blending, and equipment maintenance to ensure printing quality. In short, the varnish process is like the finishing touch in the printing industry, whether it is to enhance the brand image level or to enhance product attractiveness, it can be easily mastered.
