In the world of flexographic printing, the quality of the plates is crucial to producing precise, consistent, and high-quality print results. At Pinmark Block, a leading flexo platemaking house with decades of expertise, we ensure that every plate we produce meets the highest standards. Whether it's for flexible packaging, labels, or corrugated printing, our flexo plate making process is designed to deliver superior print quality and optimize efficiency on press.
Here, we will walk you through the detailed steps involved in creating a flexo plate, demonstrating how our method ensures high-quality flexo plates that enhance print performance.
1. Imaging the Plate or Film
The flexo plate making process begins with the imaging of the photopolymer plate or film. At Pinmark Block, we use high-resolution laser imagers to transfer the digital file directly onto the surface of the plate. This precision laser technology ensures that even the finest details are captured, leading to sharp, accurate printing.
During this stage, the laser engraves the image onto the photopolymer material, preparing the surface for exposure. The precision and resolution of this step are critical in determining the overall print quality, especially for intricate designs or high-definition prints.
Key Takeaway: Accurate imaging is essential to ensuring that your flexo plate can reproduce the smallest details, leading to better print clarity and registration.
2. UV Light Exposure
Once the imaging process is complete, the plate undergoes UV exposure. This step hardens the imaged areas of the plate, which will later become the raised surfaces used for printing.
At Pinmark Block, we use advanced UV exposure units that precisely control the amount of light applied. By doing so, we ensure that the raised areas are perfectly formed, providing a strong and durable printing surface.
This step not only defines the print areas but also enhances the plate's durability, which is crucial for maintaining print consistency across long runs.
Key Takeaway: Proper UV exposure leads to a strong plate structure, ensuring longer plate life and consistent print quality.
3. Plate Washing
After exposure, the plate is washed to remove the unexposed areas, revealing the relief image. This is a critical step in the flexo plate making process as it directly affects the plate’s performance on press.
Using specially formulated solvents and automated washout systems, we at Pinmark Block carefully remove the unexposed polymer without affecting the fine details of the image. The result is a well-defined relief structure that ensures crisp, clear impressions on a variety of substrates.
Key Takeaway: The precision washing process defines the relief depth, which impacts the ink transfer and overall print quality.
4. Drying the Plate
Once the plate has been washed, it needs to be dried to remove any residual solvent. The drying process ensures that the plate reaches its optimal hardness while retaining flexibility for the printing press.
At Pinmark Block, we use efficient drying systems that thoroughly remove solvents from the plate, minimizing any risk of distortion or shrinkage. This is important for ensuring that the plate maintains its dimensional accuracy during printing.
Key Takeaway: Proper drying is essential to prevent plate shrinkage and ensure dimensional stability, resulting in consistent print performance.
5. Post-Exposure: UVA and UVC Curing
The final step in the flexo plate making process is post-exposure, where the plate is exposed to UVA and UVC light. This process ensures that the plate is fully cured and hardened, removing any tackiness from the surface and making it ready for high-quality flexo printing.
By using both UVA and UVC light at Pinmark Block, we guarantee that the plate will withstand the rigors of high-speed printing, while maintaining excellent ink transfer properties. This step also ensures that the plate is fully durable and ready to deliver consistent, high-quality print results over extended runs.
Key Takeaway: Post-exposure is the final step to ensure the plate's hardness and durability, guaranteeing a high-quality flexo plate that can handle demanding print jobs.
