Double Layer UV Plate
A double layer UV plate is a type of plate or sheet material that is designed to protect against ultraviolet (UV) radiation. It consists of two layers of material that work together to block and absorb UV rays.The outer layer of the plate is typically made of a UV-resistant material, such as polycarbonate or acrylic. This layer is transparent and allows visible light to pass through while blocking UV rays. The inner layer is usually made of a UV-absorbing material, such as a special coating or additive. This layer absorbs the UV radiation that manages to pass through the outer layer, further reducing its transmission.

Offset Printing Press
The double-layer UV plate is compatible with offset presses commonly used in the printing industry. They can be installed on these presses to produce high-volume prints with consistent quality.
Quality Control And Proofing
In the pre-press stage, double-layer UV boards can be used for quality control and proofing. They enable printers to preview and approve final prints before mass production.
Limited Edition Prints
For limited edition prints or fine art reproductions, double-layer UV plates enable the production of high-quality, numbered and signed prints that collectors and art lovers expect.
Grassroots Level
This is the bottom layer of the board and provides a solid foundation. It is usually made of durable materials such as aluminum or polyester.
Sensitization Layer
The sensitizing layer is applied on top of the base layer. It is sensitive to ultraviolet (UV) light and plays a vital role in the platemaking process.
Cross-linked Layer
This layer is exposed to UV light during the platemaking process. UV light causes the chemicals in this layer to cross-link, creating a hardened or cross-linked surface.
Image Layer
The image layer contains the information that will be transferred to the printing substrate. It is created by exposing a printing plate to a digital or analog image source.
Coating
Coatings can be applied to protect the surface of the board and increase its durability. This layer also enhances ink adhesion and printing performance.
Backing layer
Some double layer UV panels may have a backing layer attached to the other side of the base layer. The backing layer provides additional support and stability to the board.
Resist layer
A resist layer is sometimes included to protect non-image areas from exposure to UV rays. This helps to clearly distinguish between image and non-image areas on the plate.
The material used for double-layer UV plates typically consists of a thin metal substrate, usually aluminum or steel, covered with a layer of photoactive resin. The photoactive resin is formulated to respond to ultraviolet (UV) radiation, which is used to cure and harden the resin during the plate-making process.The choice of substrate material can affect the properties of the double-layer UV plate, such as its durability, flexibility, and heat resistance. Aluminum is commonly used as it provides a lightweight yet rigid base for the plate. Steel substrates are chosen for their durability and ability to withstand higher temperatures, making them suitable for applications that require heat resistance, such as printing on corrugated cardboard.The photoactive resin layer is typically composed of acrylic or polyester resins that contain photoinitiators. These photoinitiators absorb UV radiation and trigger a chemical reaction within the resin, causing it to cure and harden. The resin layer may also include other additives to improve its adhesion to the substrate, scratch resistance, and ink receptivity.
Cleaning
Clean the plate thoroughly with a suitable cleaning solution before and after each use. Remove any ink, debris or dirt that may have accumulated on the surface. Use a soft cloth or lint-free rag to avoid scratching the plate.
Handle With Care
Handle the board with care to prevent damage. Avoid dropping or hitting the board as this may cause cracks or deformation. When handling boards, wear clean gloves to prevent fingerprints or oil from coming into contact with the surface.
Storage
Store the board in a clean, dry, dust-free environment. Keep them in their original packaging or use protective covers to protect them from scratches and exposure to moisture or contaminants.
Avoid Overexposure To Light
Although UV printing plates are designed to be exposed to ultraviolet light during the printing process, prolonged or overexposure to other forms of light may cause performance degradation. When not in use, keep the board away from direct sunlight or strong light sources.
Regular Inspection
Check the board regularly for any signs of damage, such as scratches, cracks or chips. Address any issues promptly to prevent further damage and ensure optimal print quality.
Follow Manufacturer's Instructions
Different manufacturers may have specific maintenance recommendations for their double-layer UV panels. Refer to the manufacturer's guidelines and instructions for proper cleaning, storage and handling procedures.
Calibration And Calibration Verification
If your printing device requires calibration, be sure to follow the calibration procedure regularly. Additionally, verify calibration regularly to ensure accurate print results.
The top layer of the double-layer UV plate is exposed to UV light through a negative film or digital file. The light causes the coating to harden or crosslink, creating a raised image on the plate. The non-exposed areas are then washed away, leaving a relief image on the plate. The plate is then mounted on an offset press and ink is applied to the raised image, which is transferred to the substrate during the printing process.
How to Choose the Double Layer UV Plate Correctly
Compatibility: Make sure the double-layer UV board is compatible with your press and ink system. Check the manufacturer's specifications and recommendations to ensure seamless integration.
Print Quality: Look for a board that offers high resolution and fine detail reproduction. The quality of images and text on your printouts is critical, so choose a plate that delivers sharp, clear prints.
Durability: Double-layer UV plates should be durable enough to withstand the printing process, including multiple impressions and exposure to inks and chemicals. Sturdy printing plates allow for longer printing times and fewer changes.
Ink Adhesion: Good ink adhesion is critical to producing consistent and vibrant prints. Choose plates with excellent ink retention and transfer capabilities to ensure printed images with crisp edges and vibrant colors.
Exposure Time: Consider the exposure time required for the plate. Shorter exposure times increase productivity and reduce production costs. However, it is important to find a balance between speed and print quality.
Manufacturer's Reputation: Research and choose a reputable manufacturer with a track record of producing high-quality double-layer UV panels. Read reviews and seek advice from industry professionals to make an informed decision.
Cost: While quality is important, the cost of the boards should also be considered. Compare prices from different suppliers to find a balance between quality and affordability. However, keep in mind that cheaper options may sacrifice some features or durability.
Technical Support: Technical support from the manufacturer is crucial. If you encounter any problems or have questions during plate installation or printing, look for a company that offers excellent customer service and technical assistance.
Sample Testing: Request samples from various manufacturers and conduct print tests to evaluate plate performance. This hands-on approach will allow you to see actual print results and make more informed choices.
Customization Options: If you have specific requirements, such as a special coating or finish, look for a manufacturer that offers custom options to meet your unique printing needs.
