Core Responsibilities

Primary Functions

Prepare and accurately weigh raw pigments, resins, solvents, additives, and concentrates using established recipes and batch sheets to produce printing inks that meet specification and production schedules.
Perform precise color matching using spectrophotometers, densitometers, and visual assessment under standardized lighting to ensure each lot meets customer color tolerances and industry standards.
Adjust formulations for hue, tint strength, gloss, and opacity by incrementally adding pigments and additives, documenting all changes to maintain reproducible batch records and color libraries.
Operate, monitor, and maintain mixing, dispersion, bead milling, three-roll mill, and high-shear homogenizing equipment to achieve required particle size, dispersion quality, and rheology for each ink type.
Test and measure viscosity, pH, density, tack, gloss, and drying time using viscometers, pH meters, and drying units; interpret test results and apply corrective actions to bring product into specification.
Execute small-scale lab trials to refine color recipes and process parameters prior to scale-up to production, documenting trial protocols, observations, and outcomes in technical reports.
Maintain detailed batch production records, work orders, and quality documentation in paper logs or electronic systems (ERP/MRP), ensuring traceability for each production run and compliance with internal policies.
Conduct stability, shelf-life, and performance testing (rub resistance, adhesion, wet rub, lightfastness) to verify long-term product performance and advise on product improvements.
Implement and follow Standard Operating Procedures (SOPs), Good Manufacturing Practices (GMP), and ISO-compliant processes to ensure consistent, safe, and quality-driven ink production.
Troubleshoot and resolve process, formulation, or equipment discrepancies by analyzing root causes, implementing corrective actions, and communicating findings to production and quality teams.
Monitor and control environmental parameters (temperature, humidity) during mixing and storage to prevent formulation variability and ensure consistent curing and drying characteristics.
Prepare customer samples and prototypes, annotate technical specifications and color metrics, and work directly with customers or technical service teams to finalize approvals prior to commercial runs.
Manage inventory of pigments, resins, solvents, and additives, initiate reorder requests, rotate stock according to FIFO, and coordinate with purchasing to avoid production delays.
Ensure all materials are labeled correctly, including hazard communication and MSDS/ SDS availability; handle, store, and dispose of hazardous materials in accordance with local and federal regulations.
Calibrate and maintain laboratory and production instruments (spectrophotometer, viscometer, pH meters, scales) on scheduled intervals and record calibration data for audit readiness.
Support scale-up activities by translating lab-scale formulations into production-scale recipes, modifying process times, shear rates, and dispersant levels to maintain color and physical properties.
Participate in continuous improvement initiatives such as 5S, Lean manufacturing, and Six Sigma projects to increase throughput, reduce waste, and improve batch-to-batch consistency.
Train and mentor junior blending staff and production operators on safe chemical handling, proper measuring techniques, equipment operation, and quality checkpoints to build bench strength in the blending team.
Review customer complaints and non-conforming material reports related to color or performance, perform root cause analysis, and execute corrective/preventive actions (CAPA) to prevent recurrence.
Coordinate with regulatory and environmental teams to ensure VOC emissions, waste streams, and chemical reporting (EPA, local regs) remain within compliance limits and documentation is maintained.
Label, package, and stage finished ink products for shipment, coordinating with shipping and logistics to ensure correct product delivery and accompanying technical documentation.
Maintain clean and organized laboratory and production areas, ensuring containment of spills, immediate cleanup, and documentation of any incidents to preserve safety and product integrity.
Provide technical input into new product development projects, collaborating with R&D, marketing, and sales to convert customer needs into manufacturable formulations.
Record and communicate daily production yields, scrap rates, and downtime events to production planning and management to support capacity planning and performance metrics.

Secondary Functions

Assist in maintaining and updating the company’s color libraries, databases, and digital recipe systems used by production and customer service teams.
Support cross-functional projects such as equipment upgrades, ERP implementations, and product line transitions by providing formulation and production expertise.
Participate in internal and external audits, provide process documentation, and implement audit findings to strengthen quality systems.
Generate technical summaries and production reports for management, highlighting trends, recurring issues, and opportunities for formulation or process optimization.
Coordinate with maintenance to plan preventive maintenance on blending and dispersion equipment to minimize unexpected downtime and maintain consistent production quality.
Serve as a subject matter expert during customer visits, plant tours, and sales demonstrations to explain blending processes, quality controls, and product capabilities.
Monitor industry trends in pigment technology, resin systems, and regulatory changes to recommend innovation or reformulation opportunities.
Support training initiatives and create or update SOPs, safety guidelines, and work instructions for new processes or materials.
Participate in sample exchanges and competitive benchmarking to ensure product quality remains aligned with market expectations and customer requirements.
Support ad-hoc technical requests from sales or customer service to provide quick-turn samples, color tolerancing advice, and technical clarifications.
