Halo Effect / Haloing

Ink dot or image extends beyond the intended print area reducing print quality.

Halo Effect / Haloing


  • Pressure from the plate cylinder to substrate is too high
  • LPI Anilox is too high
  • Doctor Blade tip too thick
  • Doctor blade is worn out


  • Reduce pressure between printing plate and substrate
  • Choose a lower LPI Anilox roll
  • Use a thinner doctor blade tip
  • use a longer lasting doctor blade (PowerPrint, CeraPrint, CeraFlex XT, DuroBlade)
