The StarFire SG1024 printhead may be considered for selected pigment ink applications when the specific head variant and ink formulation are compatible. Pigment inks contain solid color particles dispersed in a liquid carrier. Depending on their formulation, resin content, viscosity, and storage conditions, these inks may settle, dry, or accumulate in parts of the ink delivery system.
If deposits build up around filters, ink channels, or nozzles, jetting consistency can decline. Selecting a suitable printhead and maintaining a stable ink supply are therefore important for reliable industrial printing.
How StarFire SG1024 Features Help
Internal Ink Circulation
Selected SG1024 configurations use Fujifilm Dimatix REDIJET® ink circulation technology. Circulation helps keep compatible ink moving through designated internal passages, reducing stagnation and helping manage bubbles and sedimentation risks.
However, circulation does not eliminate pigment settling or prevent every type of blockage. Ink formulation, filtration, circulation rate, and operating conditions remain important.
Variable Droplet Control
The SG1024 family includes variants with different native and maximum droplet sizes. Variable droplet technology can support different coverage and image-detail requirements, depending on the specific model and waveform.
For pigment printing, the goal is to balance fine details with sufficient ink coverage. The correct settings depend on the substrate, ink characteristics, and desired finish.
Repairable Construction
Certain SG1024 designs feature replaceable or serviceable components, including the nozzle plate assembly. This can make targeted maintenance possible in supported configurations rather than automatically requiring replacement of the entire printhead.
Repairability depends on the exact model, the type of damage, and the availability of authorized service and replacement parts.
Confirming Pigment Ink Compatibility
Before using pigment ink, check the following:
● Exact printhead model: Confirm the SG1024 suffix and intended ink chemistry.
● Ink viscosity: Ensure the ink falls within the specified operating range.
● Particle stability: Confirm that pigment particles remain well dispersed and are compatible with the ink channels and filters.
● Waveform and temperature: Use settings validated for the chosen ink.
● Ink delivery system: Check filtration, circulation, degassing, and material compatibility.
Fujifilm lists different SG1024 variants for different fluids and applications. A specification for one variant should not be assumed to apply to the entire SG1024 family.
Suitable Applications
Depending on the head variant and ink formulation, pigment inkjet systems may be used for textile printing, graphics, or other industrial applications. The substrate, pretreatment, ink fixation, and post-processing requirements must be evaluated as part of the complete printing system.
Conclusion
The StarFire SG1024’s circulation technology, droplet control, and serviceable design can be valuable in compatible pigment ink systems. Reliable performance depends on choosing the correct variant and validating the ink, waveform, filtration, and maintenance process before production.
