Drupa Soft Gravure Thin Sleeve Technology

1. Sleeve type high mesh ceramic anilox roller

Sleeve type anilox roller structure and ultra-high energy laser engraving technology not only ensure the quality of high-precision anilox roller, but also enable rapid replacement of anilox roller.

Sleeve type anilox roller processing technology: base roller surface spraying alloy - high temperature plasma spraying ceramic powder - diamond grinding, polishing - high energy laser engraving network - fine polishing.

The ceramic anilox roller processed by YAG laser engraving technology has a smooth mesh wall, neat network wall, high smoothness, accurate ink transmission, and low scraper loss. Not only the service life of the ceramic anilox roller is long, but also the length of the printing plate can be extended. Service life.

A high-power, high-precision YAG laser engraving machine can sculpt an 1600 lpi anilox roll, and an anilox roller carved by a carbon dioxide laser engraving machine can reach up to 1000 lpi.

2. Thin sleeve flexo plate

Features of the new flexo plate: The sleeve circumference and diameter of the plate cylinder can be changed while the mandrel size is unchanged (the mandrel is not replaced). Thin-sleeve flexographic technology: First, the photosensitive resin flexo is mounted on a thin sleeve, and then imaged and rinsed. It is not necessary to form the flexographic plate and then mount it on a circular plate cylinder to avoid image distortion. .

For example, the Flexpress16 new 8-color satellite flexographic press developed by Fischer & Krecke uses a thin-walled sleeve technology, which has a low manufacturing cost and can maintain good warp accuracy during printing.

Sleeve plate cylinder structure features: Use different thickness of the sleeve, you can change the plate printing length, can shorten the preparation time, speed up the replacement of the print.

3. Sleeve type gravure impression cylinder

The main advantages of sleeve-type impression cylinders: rapid replacement of rollers; reduced material waste.

The Heliostar 2000 gravure press, produced by W&H, uses sleeve technology with a prominent gravure cylinder to provide the printer with maximum flexibility and commercial efficiency. (Text / Xu Wencai)
