ALE flexo and letterpress engraving systems use single or multiple high powered CO2 lasers or Fibre lasers to directly engrave sleeves or plates in a single step. ALE Direct laser engraving technology for flexo eliminates the costly outlay for multiple processing stages and equipment commonly associated with more conventional sleeve/plate making technologies. Direct laser engraving workflow involves few stages when compared to conventional photopolymer techniques.

ALE Hybrid Flexo systems combine CO2 laser technology with Fibre laser technology, (black materials only), to give high speed engraving with exceptional quality.

ALE machine control software, (MCS), and ALE image manipulation software, (IMS), feature soft proofing, step and repeat functions, image overlay, dot and shoulder profiling, below surface dot production and many other functions all features of ALE flexo systems.

Our flexo and letterpress engraving systems use tiff data, a common output format available from most industry RIP products. For engraving sleeves the ALE system can engrave seamless halftones for those continuous print applications. ALE supply a RIP for customers without extensive graphic departments.

Commonly used for engraving flexographic sleeves/plates, letterpress plates, many of our systems are used for special ruling rollers or decorative wallpaper rollers as well as tile printing rollers.

In addition to direct engraving our Hybrid Flexo system supplied with fibre laser technology can be used to image digital photopolymer plates, (mask ablation).


            Engrave flexo sleeves or plates, letterpress plates, decorative wallpaper rolls, tile printing rolls using ALE flexo engraving systems.
