 TopSpot E-Vision Software

 SpotCheckTM feature

  The new SpotCheckTM feature delivers live camera images from
  the actual printing position. Shape and position of the spots can
  be detected immediately after dispensing before the liquids
  evaporate.

  For optimization of the printing buffers and evaporation conditions
  the spots can be observed until completely vanished.

  Pictures can be stored from every print to document the production

  process and to ensure 100% quality.
 

 DropCheckTM feature

  With the integrated DropCheckTM function stroboscopic images
  of the droplets can be taken in flight. These pictures provide
  important information on the quality of the print head¡®s surface
  coating and the printing parameters.

  The choice of proper printing parameters for unknown solutions is
  largely facilitated by this feature!
