A code that smudges on a cold bottle or blurs at production speed is usually a technology choice, not a printer fault. A continuous inkjet printer runs a steady ink stream and steers only the droplets it needs, so small characters stay legible at line speeds that many other coders cannot hold.
Why a Continuous Stream Matters
Most inkjet coders form a droplet when told to. A CIJ machine never stops: ink leaves the nozzle continuously, an electric field deflects the droplets that should print and sends the rest into the gutter, while the head stays fixed and product runs beneath it. That is why the class is rated in hundreds of metres per minute rather than tens.
The same mechanism sets its upkeep. Because ink always circulates, a CIJ unit carries a solvent and make-up loop to hold viscosity, plus a pump and a filter. That is the honest trade: more consumable management, fewer dried-nozzle stoppages. The droplet physics are those described in the public reference on inkjet printing.
Where It Earns Its Place
Bottled and canned product is the classic case: codes land on a curved, often wet or chilled surface, the line does not slow for changeovers, and the lot must survive condensation and handling to the shelf. Cable and wire is the second case, small characters on a narrow jacket with a metre mark that stays readable after the reel is wound.
Neither case suits a slow bench job. Where output is modest and products change hourly, a simpler coder costs less to own. CIJ pays when the line is long and repetitive.
Choosing a Continuous Inkjet Printer: Five Specs
| Spec | What to set | What it decides |
|---|---|---|
| Line speed rating | Rated to 400 m/min on the SHICAI small character unit | Whether codes stay placed as the conveyor accelerates |
| Ink and surface pairing | Matched to glass, PET, metal, cable jacket or shrink sleeve | Whether the mark survives condensation, handling and paste |
| Character content | Multilingual characters, variable QR codes, barcodes, dates, serial numbers | Whether one frame covers retail, logistics and traceability codes |
| Consumable duty cycle | Ink, solvent and make-up loop plus filter service interval | How many hours between stops, and what those stops cost |
| Integration ports | USB, RS232 and TCP/IP network interface | Whether the machine takes data from the line or from an operator |
How the CIJ Line Is Built
Within a continuous inkjet printer range, this small character line is the frame most often specified for beverage, canning and cable work, and SHICAI builds it in house alongside its thermal, piezo and large character coding lines. Units ship factory-direct with the ink system matched at order stage, documentation travels with the machine, and the quality system behind the build is available for buyer review ISO 9001 quality management.
The Unit Behind This Class
Small character inkjet printer
The standard small character CIJ frame: continuous-stream printing with multilingual character and variable-data output, wired for line integration.
- Prints up to 400 m/min
- Prints multilingual characters, variable QR codes, barcodes, dates and serial numbers
- USB/RS232/TCP/IP Network Interface connectivity
Questions on CIJ
- Why does a continuous stream print at higher line speeds?
- The ink is already moving, so the machine does not wait for a droplet to form. It steers droplets into the gutter between marks, which lets the head stay put while product runs past beneath it.
- What does CIJ cost to run compared with a cartridge coder?
- More on consumables and less on stops. A CIJ unit carries ink, solvent and make-up fluid plus a pump and a filter, and it trades that for a print path that recirculates instead of drying off.
- Can one CIJ machine mark bottles, cans and cable?
- The same frame covers all three when the ink is matched to each surface and the head is mounted at the right stand-off, which is why the substrate list matters more than the model name on a quotation.
