ALE introduces the ‘Harmony 2’ engraving technology with high bandwidth pulsing capabilities combined with increased pulse energy options for processing a wider range of materials
ALE introduces its new Pronto 4 Laser Platform a revolutionary world’s first. This new laser technology is targeted at the graphical engraving market for the printing and embossing industries. Productivity will be vastly improved with 4 lasers capable of engraving simultaneously into a single focusing lens. This means all lasers end up at the same position and focus on the roller being engraved.
A simple way to think about the laser engraving of a ceramic Anilox roller is that a focused laser beam is pulsed synchronously to a roller rotating near to the focus point of the laser. The combination of the number of laser pulses around the roller, with the distance that each column of pulses are apart along the axis of the roller defines the number of Anilox cells in a given area. The position of Anilox cells from column to column facilitates the angle of the Anilox cell structure, 30, 45, 60 degrees etc. The underlying principle of a roller moving past a stationary focus laser beam is found all round the world on modern and old laser engraving machines alike
