Inkjet print system
Head boards
Special board : dropwatching
Printhead temperature
Temperature monitoring
Integrated thermistor
Additionnal temp.sensor
Heater regulation
Piezo driver
Head supply from 24V (step-up)
Waveform shape monitoring
Monitor differences from no load to full load
Single interface : fluid and electrical
Makes the printhead plug and play
Monitor fluid (pressure + temperature)
Must be easy to clean
Assembly before mounting in the machine
Cools head electronics
Protect from splash/dust
Intelligent fluid connector from CPC
Dripless
Monitoring state (disconnect/connect)
Cooling
Water cooling
Daisy-chainable
Mechanical
Dust- and ink- proof
Cover with simple interface
Matches printhead width and thickness
Print manager board
Inputs
Print go
Encoder input
Filtering
Data buffer
Power supplies
Dropwatching
Interfaces
Ethernet
Special features
Waveforms
Multiple waveform sets
At least 4 different waveform set saved in printhead board
Each set = all grey levels
Switchable on the fly while printing
Partially reconfigurable waveforms (very fast update)
Real time position compensation
Angle
For sheet to sheet printer
Cross-print direction
R2R and S2S
Use larger image area in memory and center image
Sub-drop generation
Self-sensing piezo
Automatic compensation when failling
Fully Variable Data
Design everything for the head max. data rate
Architecture
Scalable
Board synchronisation
Encoders, print go
Delay free (ethercat like?)
Simple interfaces
