Videojet Solvents and Make-Up Fluids: Matching Ink Codes Correctly
Introduction Videojet printers are widely used in industries such as beverage, food, cosmetics, electronics, and pharmaceuticals. While most users focus on ink selection, choosing the correct make-up fluid and solvent is equally critical to maintaining performance and printer longevity. This guide explains how to identify and match Videojet ink codes with their corresponding make-up fluids and cleaning solvents, helping you reduce downtime and maintain consistent print quality. 1. What Are Make-Up Fluids and Why Are They Important? Make-up fluid (also known as thinner or solvent) is used in CIJ systems to: Compensate for solvent evaporation Maintain ink viscosity and conductivity Enable proper droplet formation in the printhead Reduce the risk of nozzle clogging Each ink formula has a specific solvent base (MEK, ethanol, acetone, etc.), and using the wrong make-up can destabilize the ink system. 2. Common Videojet Ink and Make-Up Pairings Ink Code Ink Base Recommended Make-Up Application V420 / V423 MEK M513 General-purpose coding on plastic, glass, PET V705 (Soft Pigment) MEK M355 White codes on black cable and pipe V411 Ethanol M409 Food and pharma packaging, low odor requirement V393 UV-Readable M512 Security marking, invisible ink V480 Acetone M517 High-speed printing on film or foil 3. Why Ink-Make-Up Matching Is Critical Mismatching the make-up fluid and ink can lead to: Ink instability (clumping, viscosity shift) Faulty drop formation and poor code quality Frequent nozzle blockages Unnecessary wear on printhead and filters Videojet printers use a SmartCartridge™ system to minimize these risks, but **manual refills or third-party inks
