Precision laser engraving of ceramic-coated anilox rollers
Precision Anilox Roller Engraving
Anilox roller engraving is a critical component of the flexographic printing process, directly controlling the volume and uniformity of ink transferred to the printing plate. At Unidots, we provide precision laser engraving services for ceramic-coated anilox rollers, utilizing advanced Hexa and H.I.T. (High Ink Transfer) cell geometries to optimize ink delivery for each specific application.
Our engraving services cover a wide range of cell counts and volumes, from high-volume cells for solid coverage to ultra-fine cells for process color and HD printing. We work closely with our clients to specify the optimal anilox configuration based on their press type, substrate, ink system, and desired print quality, ensuring maximum performance and consistency across every print run.
Engraving Process Stages
Application Analysis
Reviewing the client's printing requirements including press type, substrate, ink system, and target print quality to determine the optimal cell geometry, count, and volume specifications.
Ceramic Coating
Applying a high-quality ceramic coating to the roller surface via plasma spray technology, creating a durable base layer that ensures long roller life and consistent engraving quality.
Laser Engraving
Using high-precision laser technology to engrave the specified cell pattern into the ceramic coating, with exact control over cell depth, opening, and wall thickness for optimal ink transfer.
Quality Inspection
Comprehensive inspection using precision measurement instruments to verify cell count, volume, depth, and surface quality, ensuring all specifications are met before delivery.
Delivery & Documentation
Delivering the finished roller with complete documentation including engraving specifications, measurement reports, and recommended handling and maintenance guidelines.
