Ink adhesion problems on a narrow web press cost you time, material, and customer confidence. QC Electronics narrow web corona treaters drop directly into any flexographic press—no modifications required—delivering consistent surface energy for reliable ink adhesion on labels, tags, and flexible packaging.
Get a Quote → Talk to an EngineerNarrow web flexographic presses run a wide variety of substrates (film facestock, paper, synthetics, metallized materials) often changing between jobs multiple times per shift. Each substrate arrives with a different surface energy level, and that level may have decayed significantly since it was treated at the extrusion line.
When surface energy is too low, ink won’t wet out properly. You get poor color density, pinholing, adhesion failures on tape test, and inconsistent print quality across the web. On narrow web presses running at high speeds in tight spaces, there’s no room for a second chance—the ink either sticks or it doesn’t.
The challenge is compounded by the shift toward water-based and UV-curable inks in the label industry. Both have higher surface tension than solvent-based inks, requiring higher substrate surface energy for reliable wet-out. Without in-line corona treatment, you’re relying entirely on pre-treatment levels that may or may not be adequate by the time the film reaches your press.
QC narrow web corona treaters are designed to integrate directly into your existing press—no modifications, no mechanical changes, no downtime for installation. Compact, high-power treatment positioned immediately before the print station ensures every substrate has the surface energy your ink demands, regardless of what arrived on the roll.
Even when your label stock arrives with acceptable dyne levels, an in-line corona treater acts as a safety net. Dyne levels don’t tell the whole story—additives, surface contamination, and storage conditions all affect adhesion in ways a dyne pen can’t measure.
Industry experts report that freshly treated material provides better adhesion than aged material at the same measured dyne level. A corona treater on your press ensures every job starts with a fresh, clean, fully activated surface, eliminating the guesswork that comes with relying on pre-treatment alone.
Purpose-built for the space constraints and production demands of narrow web flexographic presses. Every system is configured to your press, substrate mix, and ink chemistry.
Compact, high-power treater that drops directly into any flexographic press. No modifications required. Treats any conductive or nonconductive substrate up to 60 mil thickness.
Automatic watt density control ramps proportionally with line speed critical for narrow web presses that frequently change speed. Touchscreen with recipe storage for fast job changeovers.
Every substrate gets freshly treated immediately before the print station — eliminating adhesion failures caused by decayed pre-treatment or inconsistent incoming dyne levels.
Proper surface energy ensures ink wets out evenly across the web. Sharper images, richer color density, and consistent coverage — even on difficult substrates like metallized films.
Stop rejecting jobs because of adhesion problems. Stop re-running orders. Stop troubleshooting ink issues that trace back to surface energy. The treater handles it before the ink ever touches the substrate.
Take on jobs with substrates you couldn’t reliably print before. In-line treatment gives you the confidence to quote a wider range of materials — expanding your capabilities and your revenue.
We gather details about your substrate, ink type, line speed, treat width, and production environment.
Ship us your substrate. We run it through our treaters and measure dyne levels to determine optimal treatment parameters.
