Key Responsibilities and Required Skills for Ink Technician

🎯 Role Definition

An Ink Technician is a hands-on manufacturing and lab professional responsible for formulating, mixing, testing, and maintaining inks and coatings to meet customer color, performance, and regulatory specifications. This role combines chemistry, print technology and process troubleshooting: you will work with color measurement tools (spectrophotometers), viscosity and rheology instruments, press operators, suppliers and quality systems (ISO/GMP) to ensure consistent, printable and compliant ink batches for high-volume production. Ideal candidates have practical experience with ink formulation, pressroom color matching, solvent handling, and strong documentation practices.

Core Responsibilities

Primary Functions

Formulate and prepare ink batches according to written recipes and production specifications, measuring and dispensing pigments, resins, solvents and additives precisely to achieve target color, viscosity and drying profiles.
Perform color matching and color correction using spectrophotometers, densitometers and color management software (Pantone, Lab* targets), documenting delta E and making iterative adjustments to achieve customer-approved matches.
Measure and control ink viscosity, rheology and density using Brookfield viscometers, Zahn cups and density meters; adjust formulations for consistent printability on flexo, gravure, offset and digital presses.
Conduct laboratory tests for ink properties including drying time, rub resistance, adhesion, gloss, opacity, pH, conductivity and stability under accelerated aging conditions; interpret results and recommend corrective actions.
Troubleshoot pressroom ink issues in real time—such as poor transfer, mottling, set-off, wash-up, and smearing—by analyzing press parameters, substrate interactions and ink formulation variables, then implementing fixes to reduce downtime.
Maintain accurate batch records, material traceability, quality control logs and production documentation in compliance with ISO, GMP and customer-specific quality systems, ensuring full audit readiness.
Operate and maintain lab and mixing equipment including high-speed dispersers, bead mills, homogenizers, mills and mixers; perform routine equipment cleaning, calibration and minor repairs.
Manage ink inventory, monitor raw material lot changes, perform cycle counts, and coordinate with purchasing to ensure supply of pigments, resins and solvents while minimizing waste and cost.
Implement solvent recovery, VOC control and waste-reduction practices, and ensure proper labeling, storage and disposal of hazardous materials in accordance with MSDS, local regulations and company EHS programs.
Support scale-up from lab batches to production runs by validating formulations at pilot scale and communicating adjustments required for full-scale manufacturing.
Prepare and maintain material safety data sheets (MSDS) and safety documentation for new formulations; train press operators and production staff on safe handling, spill response and PPE requirements.
Collaborate with customers, account managers and technical service teams to develop custom ink solutions, perform press trials, and document approvals and change controls for new or updated products.
Run and evaluate print trials, compare printed samples against customer standards, and produce technical reports recommending formula tweaks, press settings or substrate changes to meet specifications.
Validate raw material substitutions and alternate suppliers by running compatibility and performance checks to ensure consistent color, rheology and print performance.
Participate in continuous improvement initiatives (Lean, Six Sigma) to optimize mixing times, reduce scrap, standardize recipes and improve yield across ink production processes.
Maintain calibration and certification records for laboratory instruments; schedule vendor service and calibrations to preserve measurement accuracy for color and viscosity instrumentation.
Investigate customer complaints and nonconformances related to ink performance, root-cause analyze production or formulation failures, and implement corrective and preventive actions (CAPA).
Train and mentor junior technicians, press operators and new hires on formulation basics, color matching techniques, safe material handling, and standard operating procedures (SOPs).
Support new product development projects by documenting experimental formulations, test plans, sample distribution, and providing feedback to R&D and commercial teams.
Ensure manufacturing readiness by preparing pre-production samples, generating production worksheets, and coordinating with scheduling and maintenance teams to meet delivery timelines.
Monitor regulatory changes and coordinate with compliance teams for VOC limits, food-contact certifications, and other regulatory requirements relevant to ink compositions and intended end-uses.
Maintain an organized, clean and safe lab and mixing area to reduce cross-contamination risks and ensure reproducible, high-quality ink production.

Secondary Functions

Support production planning by estimating ink batch times and material needs to align with press schedules and minimize changeover.
Maintain ongoing communication with suppliers to expedite raw material availability and qualify new pigments and additives.
Participate in cross-functional problem solving with quality, production, maintenance and R&D to resolve recurring printability or stability issues.
Assist with ISO/GMP documentation updates and internal audits related to ink formulation and production processes.
Provide technical content for SDS updates, product data sheets and training materials for both internal teams and customers.
