Core Responsibilities

Primary Functions

Prepare, weigh and accurately dispense raw materials for ink batches following standard operating procedures and batch records, ensuring precise formulation and chemical stoichiometry for consistent printing performance, color strength and adhesion.
Execute ink formulation and production runs for water-based, solvent-based and UV-curable ink systems, including dispersion, milling, letdown and let-up stages, and verify that each step meets specified time, temperature and shear requirements.
Perform in-line and off-line quality checks on wet and dried inks, including viscosity (Brookfield/Cup & Bob), pH, solids content, tack, drying speed, gloss, and film appearance; document results and initiate corrective actions when specifications are not met.
Conduct color matching using spectrophotometers, visual matching standards, and Pantone/CMYK references; adjust pigment load, undertone and opacity to achieve target Delta E and customer color tolerances.
Operate and maintain mills, high-shear dispersers, mixers, homogenizers and filtration equipment; perform routine setup, troubleshooting, and minor mechanical adjustments to maintain process reliability and product quality.
Lead scale-up activities from lab formulations to pilot and full-scale production, validating process parameters, transfer protocols and raw material substitutions to ensure reproducibility and manufacturability.
Monitor and control rheology and flow properties by selecting and dosing rheology modifiers, thickeners, surfactants and solvents to achieve targeted printing performance across flexographic, gravure, screen and digital printing presses.
Implement and document corrective actions and root cause analyses for out-of-specification batches, coordinate rework plans, and update batch records and SOPs to prevent recurrence and improve first-pass yield.
Maintain accurate production documentation including batch logs, raw material usage reports, QC test sheets, changeover checklists and lot traceability records to meet internal and external audit requirements.
Conduct stability and aging studies on ink batches, recording changes in viscosity, gloss, color and sedimentation over time and recommending formulation adjustments or preservation strategies as needed.
Ensure compliance with health, safety and environmental regulations by following OSHA guidelines, MSDS/SDS procedures, proper use of PPE, safe handling and storage of flammable/volatile materials, and appropriate waste disposal practices.
Communicate proactively with R&D, quality assurance, procurement and production planners to coordinate raw material availability, schedule production runs, and align formulation changes with inventory control.
Optimize manufacturing processes through continuous improvement initiatives—lean manufacturing, 5S, kaizen events, and statistical process control (SPC)—to reduce waste, lower scrap rates and improve throughput.
Train and mentor junior production operators on correct weighing, mixing, sampling, and QC test procedures, promoting best practices for product consistency and workplace safety.
Perform routine maintenance checks and schedule preventative maintenance with the maintenance team for mixers, grinders, pumps and filtration systems to minimize downtime and extend equipment life.
Evaluate and qualify new raw materials, pigments, resins and additives by conducting lab trials and pilot runs, documenting performance impacts on color, stability, adhesion and printability.
Support customer-specific customization requests by developing bespoke formulations, preparing small-scale samples, and providing technical documentation and performance data to sales and technical service teams.
Maintain inventory control of critical raw materials and pigments, flagging shortages, managing lot rotation, and assisting procurement with vendor evaluations when supply quality impacts production targets.
Participate in cross-functional troubleshooting for printing defects (e.g., set-off, ink transfer, mottling) by analyzing process variables, recommending formulation or press-setting modifications, and validating corrective measures on press.
Adhere to quality management systems such as ISO 9001 and Good Manufacturing Practices (GMP) where applicable, participate in internal and external audits and implement audit findings.
Prepare safety and regulatory documentation including ingredient declarations, GHS labeling, SDS updates and product safety data to support global regulatory compliance and customer requirements.
Collaborate with the R&D team on pigment selection, dispersant strategies and binder optimization to improve opacity, rub resistance, lightfastness and adhesion for specified substrates (paper, film, foil, textiles).
Monitor energy usage and solvent recovery systems, recommending process or equipment changes to reduce VOC emissions and improve environmental sustainability and cost efficiency.

Secondary Functions

Support pilot testing and small-batch production for new product launches, providing hands-on feedback to R&D and product managers during market validation.
Assist quality and regulatory teams in preparing technical dossiers and customer specification sheets, including test methods and acceptance criteria for custom ink blends.
Maintain calibration and validation schedules for critical test instruments (spectrophotometer, viscometer, pH meter) and coordinate calibration services with external vendors when needed.
Participate in cross-training initiatives across shifts to build manufacturing resilience and ensure consistent production knowledge across teams.
Help evaluate and implement new manufacturing technologies, digital batching systems and formulation management tools to increase traceability and reduce human error.
Provide technical support to customers and field service teams on troubleshooting print-related issues, offering recommendations for ink adjustments or press optimizations.
Prepare and review change control documentation for formulation or process changes, ensuring appropriate approvals and communication to production, QA and sales stakeholders.
Support sustainability initiatives by evaluating bio-based solvents, low-VOC formulations and recycled-content pigments for feasibility in current production lines.
