The HVP engraving allows customers to combine good solids and tonal areas on one plate. It does this by combining high line counts and high volume through its unique cell design. This is different from conventional 60° engravings that are only capable of offering either a high volume or a high line count but not both. It does this without compromising the crucial release characteristics of the anilox.

Increased line counts and a larger number of cells per sq/cm mean that there is improvement in ink lay and ink release. The better ink release also extends anilox life.

Having a reliable combination anilox enables customers to print fine vignettes and intermediate area without large deposits of ink bridging and filling in, allowing customers to reduce the size of their inventory.

High Volume Process – Combination Engraving (Solid and Tone)

  • High line count, high volume engraving offering numerous benefits.
  • Combines solids and tonal print on one plate not possible with conventional 60° engravings.
  • Increased print latitude for one anilox, helping reduce anilox inventories.
  • Improved solids, reducing pin-holing and improving lay.
  • Greater release characteristics helping keep print cleaner on the run Increased lifespan on wear against conventional 60° engraving.
  • Increased cleaning characteristics.

The HVP is a highly versatile engraving and took eighteen months of research and development to perfect. Our laser technicians have designed strict tolerances to work to in order to maintain the crucial release characteristics necessary to provide such excellent solids whilst maintaining high line counts. Sandon Global have specific Standard Operating Procedures concentrating on the crucial tri-axial ratios that our laser technicians and finishing operatives work to in order to produce this cell format consistently each time.

Fig.2 The tri-axial ratios that our staff work to in order to produce consistent engravings. Due to these tri-axial ratios our HVP engraving is capable of producing solid print that is far in advance of conventional 60° engravings. The improved release characteristics of the HVP engraving evacuate more ink from their cells, which helps eliminate pin-holing issues and reduces ink starvation, maintaining good optical density at up to 600 m/pm.

Sandon believe the HVP is the best combination anilox in the industry. And we back Sandon.
