Frequently Asked Questions
What is the difference between the Galaxy PH 256/30 and the Galaxy JA 256/30?
Both are Fujifilm Dimatix Spectra Galaxy printhead platforms with the same core jetting specs: 256 nozzles, 254 µm nozzle spacing, 36 µm nozzle diameter, 28 pl calibrated drop, 25–30 pl adjustable range, 20 kHz firing frequency, up to 90°C operating temperature, and compatibility with organic solvents, UV-curable, and aqueous inks. The critical difference is electronics integration. The PH (Printhead) includes complete on-board signal processing and drive electronics — it is a self-contained unit that plugs directly into printer systems designed for the PH interface. The JA (Jetting Assembly) is the bare piezoelectric jetting module without any on-board electronics — it requires an external drive board and is the variant used in VUTEk PressVu, HP Scitex FB6100, Inca Eagle, NUR Tempo, and many other wide-format platforms. Installing the wrong variant in a printer will result in electrical incompatibility and jetting failure.
What does "all jets can be fired simultaneously or individually" mean in practice?
The Galaxy PH 256/30's serial-to-parallel converter architecture allows each of the 256 nozzles to be addressed independently — firing any combination of nozzles simultaneously or in any sequence. This independent addressability is what enables full image data to be converted from serial data input into parallel firing commands in real time. It is the foundation of the head's grayscale and variable-dot capability, and allows the printer's RIP to achieve precise dot placement at up to 900 dpi without waveform conflicts between adjacent channels.
Is the Galaxy PH 256/30 suitable for UV inks at high temperatures?
Yes — the Galaxy PH 256/30 AAA is rated for operating temperatures up to 90°C and is compatible with UV-curable inks alongside organic solvents and aqueous fluids. The elevated operating temperature range is important for UV ink applications because UV inks typically require heating to reach the 10–14 cP viscosity range needed for stable jetting. The top-mounted fluid interface and multiple mounting configurations allow integration into heated ink delivery systems. Always verify that your UV ink formulation falls within the head's ink compatibility parameters before deployment.
Do you ship the Spectra Galaxy PH 256/30 AAA to Latin America?
Yes — same day shipping from our Doral, Miami FL warehouse before 2PM EST. Our Miami location is ideal for Latin American wide-format UV and solvent production shops using freight forwarders in the Doral area.
