SEMITI INK-1 vs Chemours Ti-Pure R-931

SEMITI INK-1 matches Ti-Pure R-931 as an easy-dispersion ink-grade rutile for offset, flexo, gravure, and UV inks.

Ti-Pure R-931 is the global reference ink-grade rutile — engineered for fast bead-mill dispersion, anti-screen-blinding behavior, and tight color spec for high-volume ink production. SEMITI INK-1 is the direct functional alternative.

Common questions

Can SEMITI INK-1 substitute Ti-Pure R-931 directly in flexo and gravure white ink?+
Yes for general-purpose ink. Test on your bead mill: measure dispersion time to Hegman 7 and 24-hr anilox roll behavior at 220 mesh. First-time pass rate is typically 95% for general-purpose commercial printing ink. Both share matched particle size D50 of 0.25 μm ± 0.02.
How much cheaper is SEMITI INK-1 vs Ti-Pure R-931?+
Ti-Pure R-931 lands in Asia at USD 3.60–4.00/kg; SEMITI INK-1 at USD 2.40–2.80/kg — approximately 35% lower. For high-volume white ink producers, this cost difference directly improves margin on a price-sensitive commodity product.
When should I keep using Ti-Pure R-931 instead of switching to SEMITI INK-1?+
Keep R-931 when your application is premium specialty ink — security ink, banknote ink, or pharmaceutical packaging — where R-931 is named in the specification. For standard commercial offset, flexo, gravure, and UV white ink production, SEMITI INK-1 is the right economic substitute.
