InkTek RO Mixing Flo Blue Plastisol Ink – Custom Color Creations

Why is my fluorescent blue not as bright as expected?

Fluorescent blues are naturally less intense than fluorescent yellows and pinks, and they depend heavily on a bright white underneath. Print over a flashed white underbase on anything but a white garment.

Does it glow under blacklight?

Fluorescent pigments react strongly to UV light, so fluorescent blue prints typically stand out under blacklight. Test on your actual garment and underbase for the effect you want.

Will RO work with the formulas I already have?

The RO system is matched shade-for-shade to the industry’s most widely used 18-color low-cure mixing system, with the same 18-color structure, so weight-based formulas built on that structure carry across. Mix your most-used formulas first and pull drawdowns alongside your current ink before converting production. We can help — send us your formulas.

What temperature does RO cure at?

280°F across the entire ink film, held at or above temperature for 5–10 seconds. It is a low-cure plastisol, so it can run on the same design as standard 320°F inks — just cure to the higher requirement. Verify cure with a donut probe rather than a surface reading.

Can I print it straight from the can?

Yes. Every RO color is a finished, press-ready ink balanced for viscosity. Print it as-is, or weigh it into a formula with other RO colors.

What mesh counts work best?

110–305 threads per inch, at 25–35 N/cm² tension. Lower counts lay more ink for opacity; higher counts hold detail. Unsure what mesh is on your screens? Use a mesh count determiner.

Can I print it on polyester?

Yes, with care. The system performs best on 100% cotton. On polyester and blends, print over a low-bleed white or bleed blocker to control dye migration, and do not overshoot time at temperature.

What about stretchy fabrics?

For lycra, spandex and performance stretch, add a stretch additive or print over a stretch underbase. See our additives and special effects.

How should I mix colors accurately?

By weight on a scale — zero the container, add each component to its target weight, and mix thoroughly. Weight is far more repeatable than volume. For larger batches, an ink mixer saves time and gives a more consistent blend.

Which size should I buy?

Buy a quart to sample and pull drawdowns, then move to gallons or 5-gallons for production. Switching the whole ink room? The RO mixing system kit gets you all 18 colors at once.
