UV-active stamping ink EUROLITE 51108003 Transparent Red 250 ml – UV-reactive stamp ink, solvent-based

EUROLITE UV-active stamping ink Transparent Red, 250 ml, is a solvent-based ink formulated for use with rubber and polymer stamps. The transparent red shade appears nearly invisible in normal lighting and fluoresces under UV light, enabling discreet marking and easy detection during inspections. Supplied ready-to-use in a 250 ml bottle, the ink offers consistent flow for clear, legible imprints on paper, cardboard and many packaging surfaces.

Advantages

The solvent-based composition ensures rapid drying and strong adhesion on porous substrates while maintaining transparency under visible light. Under UV illumination the ink exhibits bright fluorescence in red tones, facilitating quick identification without altering the visible appearance of marked items. Packaged in a 250 ml bottle, the ink is convenient for repeated use and provides uniform saturation for reliable stamp impressions.

Suitable for

• Document marking and validation where covert UV visibility is required
• Packaging checks and inventory control with invisible day‑to‑day appearance
• Event access control using wristbands or tickets marked for UV inspection
• Security checks and anti-counterfeiting measures on paper and board

Key specifications

• Color appearance: transparent red in visible light, fluorescent red under UV
• Volume: 250 ml ready-to-use bottle
• Base: solvent-based formulation
• Compatible stamp types: rubber and polymer stamps
• Drying behavior: fast drying on porous substrates
• Suitable substrates: paper, cardboard and many coated packaging surfaces (test before use)

How to use

Shake the bottle gently before use to ensure uniform pigment distribution. Apply a moderate amount of ink to the stamp pad or directly to the stamp surface, testing on scrap material to confirm imprint quality and drying time. Press the stamp firmly and evenly onto the intended substrate. Allow the imprint to dry fully before stacking or packaging to avoid smudging. Clean stamps and pads with a solvent-compatible cleaning agent recommended for solvent-based inks.

Usage recommendations

Store the ink in a cool, dry place away from direct sunlight and heat sources. Use in well-ventilated areas and follow safety instructions for solvent-based products. Test compatibility on a small area of non-critical material prior to full application to confirm adhesion and appearance.
