DSA Inkjet – Drop Shape Analyzer

Analyzing jetted drops for precision printing

The all-important cooperation between the ink and the print head control creates high quality inkjet printing. The DSA Inkjet Drop Shape Analyzer supports you in reaching this goal. The instrument incorporates an innovative Drop Watching system for analyzing the jet stream of ink droplets produced by the print head. Drop formation and analysis are exactly synchronized by triggering drop generation.

  • Optimizing printing parameters and print heads in inkjet printing
  • Ink development
  • Precision improvement in 3D printing
