Frequently Asked Questions
Why does the VUTEk PressVu UV 200/600 use different Galaxy heads for colour vs white channels?
The VUTEk PressVu UV 200/600 uses the Galaxy JA 256/30 AAA (30 pl calibrated) for its CMYK colour channels, where a smaller drop produces finer colour accuracy and smoother gradations. The white ink channel uses this Galaxy JA 256/50 AAA (50 pl calibrated) because white ink requires a larger drop volume for sufficient opacity and coverage — you need more ink per dot to produce a truly opaque white layer. Using the wrong head for either channel will result in incorrect opacity (white), poor colour accuracy and gradation (colour), or outright head incompatibility. Always confirm your channel position before ordering.
What is the VUTEk metallic base — and why is it not included?
On VUTEk PressVu UV printers, the Galaxy JA 256/50 printhead mounts into a proprietary metallic base bracket (VUTEk part number AA92037 ASM refers to the complete head-and-base assembly). When ordering a replacement head, the metallic base from your existing failed head is typically reusable — it is a mechanical mounting component that does not wear out with the head. The Galaxy JA 256/50 AAA ships as the printhead only. To build the complete VUTEk-compatible assembly, you need a Jetpack build service (PPHVU13771) and a JIG alignment tool (PMEDI8100). Contact our team to confirm which accessories you need for your specific VUTEk model before ordering.
How does the Galaxy JA 256/50 AAA differ from the Galaxy JA 256/80 AAA?
Both are 256-nozzle, 254 micron spacing, 20 kHz, 450–600 dpi Spectra Galaxy heads with the same 4 × 64 piezoelectric slice architecture and top-mounted interfaces. The key difference is drop size: the JA 256/50 has a 50 pl calibrated drop (45–55 pl adjustable range) and reaches 600 dpi maximum resolution, while the JA 256/80 has an 80 pl calibrated drop (75–85 pl range) and is limited to 450 dpi. The 50 pl head is for colour channels requiring finer image quality; the 80 pl head is for white ink channels requiring higher ink coverage and opacity. On the Agfa Anapurna XL², these two heads serve different channel positions and are not interchangeable.
Do you ship the Spectra Galaxy JA 256/50 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 VUTEk PressVu, Agfa Anapurna, and UV wide-format production shops using freight forwarders in the Doral area.
