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

1. Why Ink Troubleshooting Is Crucial in Industrial Printing In high-speed production environments, print defects can lead to: Product rejection Packaging recalls Regulatory non-compliance Equipment downtime Increased operational costs Early detection and proper resolution of ink issues ensure consistent performance, lower maintenance costs, and better customer satisfaction. 2. Common Inkjet Printing Problems and Symptoms Issue Visual Symptom Fading Weak or disappearing text Smudging Ink wipes off easily or doesn’t dry Nozzle Blockage Missing dots, distorted characters Ink Spread Blurred or enlarged print area Ink Not Ejecting Printer not printing anything 3. Fading Prints: Causes and Solutions Cause Solution Ink is expired or poorly stored Replace ink; check date and storage conditions Incorrect ink for substrate Use ink with better adhesion for that surface Substrate contamination (oil, dust) Clean substrate before printing Ink layer too thin Increase font boldness or use pigment ink Tip: Use pigmented ink for higher opacity and UV resistance. 4. Ink Smudging or Slow Drying Cause Solution Ink drying too slowly Switch to faster-dry ink (e.g., MEK-based) High humidity or cold environment Adjust ambient conditions or drying process Printing on non-absorbent film Use solvent-based or specialized film ink Over-inked characters Reduce font size or drop volume Tip: Use acetone-based or fast-dry MEK ink on flexible films or foils. 5. Nozzle Blockage or Ink Not Ejecting Cause Solution Dried ink in nozzle Clean with compatible cleaning fluid Pigment settling in the ink Shake ink, agitate tank, or replace filter Printer not flushed after shutdown Perform automated or manual

1. What Are Pigments in Inkjet Printing? Pigments are tiny solid particles suspended in ink that give it color and opacity. Unlike dyes, which dissolve into the ink fluid, pigments remain as particles — making them more resistant to fading, heat, and chemical exposure. Common Pigments: Titanium Dioxide (White) Carbon Black Chromate Compounds (Yellow/Red) Metallics (Aluminum flakes, mica-based) Pigments are essential for high-contrast coding, especially on dark surfaces or when long-term readability is required. 2. Pigment Ink vs. Dye Ink: What’s the Difference? Feature Pigment Ink Dye Ink Solubility Insoluble particles suspended in fluid Fully dissolved in solvent Color Intensity High opacity, slightly duller tones Brighter, more transparent Durability Highly resistant to light, water, heat Can fade or run over time Substrate Coverage Excellent on dark/non-porous materials Limited unless used on light backgrounds Clogging Risk Higher (requires circulation system) Lower maintenance 3. When Should You Use Pigmented Ink? ✅ Dark surfaces (black or red plastic, rubber, or metal)✅ High-contrast readability is essential (e.g., white/yellow on cable)✅ Outdoor or harsh environments (heat, sunlight, moisture)✅ Security or branding marks requiring permanence✅ Compliance coding where contrast is legally required 4. Common Pigmented Ink Colors and Their Uses Color Pigment Base Typical Application White Titanium Dioxide (TiO₂) Black cables, rubber, plastic containers Yellow Diarylide or Bismuth compounds Red cables, color-coded pipes Black Carbon Black General high-contrast, UV-resistant Red Iron Oxide or Chromate Wires, packaging branding Silver/Gold Metallic flakes Decorative codes, branding, security 5. Printer Compatibility and Ink Circulation Requirements Pigmented inks are heavier and

1. Why Ink Shelf Life Matters in Industrial Printing Expired or improperly stored ink can cause: Print defects (smudging, fading, clogging) Nozzle blockages and downtime Increased cleaning and maintenance costs Waste of expensive consumables Compliance risks in regulated industries Proper storage helps you maintain print quality, minimize waste, and protect your equipment investment. 2. Typical Shelf Life by Ink Type Ink Type Average Shelf Life Notes CIJ Dye-Based (MEK) 12–18 months Stable if stored sealed and upright Pigmented Inks 6–12 months Require mixing/shaking; prone to settling TIJ Cartridge Ink 9–12 months Shorter if cartridge is opened DOD High Viscosity 12–24 months Oil- or resin-based, stable in sealed drums UV Inks 6–9 months Light-sensitive; store in opaque containers Solvents (Make-Up) 12–24 months Flammable; proper sealing is essential Always refer to the manufacturer’s label and MSDS for specific expiry dates. 3. How to Read Expiry Dates on Ink Bottles Most ink bottles are labeled with: Manufacture Date (MFG) – When ink was produced Expiration Date (EXP) – Last recommended use date Batch/Lot Number – Useful for tracking quality and recalls Tip: Use a “First-In, First-Out” (FIFO) system to manage inventory rotation. 4. Ideal Storage Conditions for Ink and Solvents Storage Parameter Recommended Setting Temperature 10°C to 30°C (50°F to 86°F) Humidity <70% RH (avoid excessive moisture) Light Store in a dark, shaded area Position Store upright, especially for cartridges Container Seal Keep tightly sealed when not in use Avoid: Freezing temperatures (causes pigment separation or gelling) Direct sunlight (UV can degrade ink
