Why printing white twice isn't a waste — it's what lets you achieve gradients and depth a single pass can't. I cover the whole process in a video, with all the technical parameters.

White ink doesn't cover on black.

It's not the ink's fault.

After 45 years in the shop, I can tell you that with certainty.

→ Insufficient deposit — white ink carries titanium dioxide (TiO₂), the heaviest pigment there is. The mesh theoretical volume must be sized for that pigment load, not for a process colour.

→ Wrong rheology — water-based white is thixotropic: if it's cold or under-stirred, the squeegee can't shear it enough to flow properly. The result is a broken film — not an off-contact issue.

→ Squeegee not calibrated — a blade harder than 70 Shore A or an aggressive angle scrapes the ink off instead of depositing it. Before changing your mesh, check your squeegee geometry and hardness.
Off-contact and double stroke are still useful variables — but they are compensations, not root causes. If the first three are wrong, no double pass will save you.

I made a full video on white ink technique — double stroke, mesh selection, ink setup.

Water-based inks cost more.
I know.

But the math doesn't add up if you only look at the price per kilo.

Lower disposal costs. Less ventilation. Softer hand feel = fewer rejects. Premium positioning for the finished product.

And -50% carbon footprint vs traditional plastisol.

I put it all in a new free infographic - data, direct comparisons, certifications.

Ink bleeding at the edges?

Before changing your ink, stop for a second.
Bleeding is almost never the ink's fault. It's about how the ink behaves during printing — and that behaviour has a precise name: rheology.
Viscosity too low → ink drains through the mesh by gravity between strokes.�Print speed too high → shear rate increases, viscosity drops, the dot spreads.�Snap-off poorly calibrated → ink doesn't have time to "solidify" before the mesh releases.

Not magic. Physics.

If you use Virus® Inks, you already know that results depend on the process — not just the ink.

Mesh tension, halftone geometry, defect diagnosis: these are the variables that determine whether your ink performs as it was designed to.

We've put together the three most technical ebooks in the BQ eLearning collection in one bundle. For professionals who want to control every variable in the process.

Launch price: $49.90 until June 8th.

If your water-based inks aren't performing as expected, check your mesh tension before changing the formulation.

At 15 N/cm, off-contact sits at 4-5 mm and image distortion reaches 1.8 mm/m. These conditions make it impossible for any ink — no matter how well formulated — to deliver consistent results.

At 32 N/cm, off-contact drops to 1-2 mm. Distortion falls to 0.1%. The ink can finally do what it was designed to do.

We wrote down the protocol. Free sheet — because good ink deserves a properly tensioned screen.

If you use water-based inks, you already know: the difference between excellent and average is in the details you control before printing.

The Error Library is one of those details.

A simple but powerful tool: every defect documented, every cause analysed, every solution recorded with the technical parameters that made it work. Mesh tension, off-contact, curing temperature.

Beppe Quaglia wrote down how to build one. Template, 12-month roadmap, golden rules.

Free sheet, no strings attached.
