In the modern print shop, composite sleeves are essential for their lightweight properties and versatility. However, to ensure they deliver the precision required for high-quality labels and packaging, specific handling protocols must be followed. At Rotometal, we believe that the life of a tool is determined long before it hits the press.
Because sleeves are lightweight, they are often handled less carefully than heavy steel cylinders. This is a mistake. Gentle handling is crucial to maintain performance. Always use protective gloves and appropriate grips, and never subject a sleeve to striking or dropping, which can compromise the internal structure.
Post-print cleaning is vital, but the wrong chemicals are a "silent killer" for composites. We recommend a mixture of ethyl alcohol and ethyl acetate. The critical detail? Ensure the ethyl acetate concentration does not exceed 20% to avoid damaging the composite surface.
Dimensional stability is the backbone of print registration. To prevent deformation, sleeves must be stored:
Horizontally: On racks providing support along the entire length.
At Room Temperature: Ideally between 18-25°C.
In Controlled Humidity: Between 40-60% to prevent material degradation.
Precision fitting is mandatory for optimal print quality. This requires regular calibration of mounting systems and careful monitoring of clamping pressure. Excessive pressure can lead to surface damage, negatively affecting both durability and performance.
By following these manufacturer-backed guidelines, you ensure that your Rotometal tooling remains a reliable asset for years to come.
