Core Responsibilities

Primary Functions

Lead development and optimization of new and improved ink formulations (water-based, solvent-based, UV-curable, plastisol, and UV LED) to meet customer performance specifications, cost targets, and environmental requirements.
Perform precise color matching using spectrophotometers and color management systems; produce CIE Lab* targets and iterate blends to achieve repeatable matches across substrates and print technologies.
Conduct lab-scale and pilot-scale production of inks, including pigment dispersion, milling, mixing, filtering and deaeration, ensuring batch-to-batch consistency and scalable process parameters.
Troubleshoot printing defects (mottle, set-off, flocculation, streaking, rub resistance, blocking) by diagnosing root causes (formulation, press settings, substrate, environmental conditions) and implementing corrective actions.
Define and control rheology (viscosity, thixotropy, yield stress) and surface tension properties for specific print processes by adjusting rheology modifiers, solvents, resin content and pigment grind.
Develop and maintain ink stability protocols, performing accelerated aging, freeze/thaw, and shelf-life testing; recommend packaging, storage and handling best practices to maximize product life.
Perform particle size analysis, grind gauge assessment and dispersion quality checks to ensure pigment wetting and uniformity for optical clarity, opacity and gloss control.
Conduct substrate compatibility testing and adhesion trials across paper, film, foil, corrugated, textiles, and specialty substrates to ensure ink performance and adhesion under targeted end-use conditions.
Implement and execute lab and production trials on customer sites or internal pilot presses; collect printability data, adjust formulations in situ, and provide technical support to production crews.
Maintain regulatory and product stewardship responsibilities, ensuring inks comply with relevant regulations (REACH, TSCA, Prop 65, RoHS, FDA indirect food contact guidance where applicable) and prepare Safety Data Sheets (SDS).
Collaborate with procurement and suppliers to evaluate pigments, resins, additives and dispersants; conduct vendor trials and qualify raw material sources based on quality, cost and sustainability criteria.
Generate technical documentation including batch records, standard operating procedures (SOPs), formulation records, QC test protocols and product data sheets for manufacturing and customer handoff.
Apply statistical methods, DOE (Design of Experiments) and process control tools to optimize formulations and manufacturing parameters while minimizing waste and improving yields.
Support scale-up from laboratory to pilot to full production runs, defining process parameters (mixing speeds, pass counts, mill energy) and controlling critical-to-quality variables to ensure consistent product transfer.
Provide technical training and mentorship to production, laboratory and customer service teams on ink handling, color matching, and problem-solving techniques.
Evaluate environmental and sustainability opportunities for ink portfolios (low-VOC, bio-based solvents, recyclable/resin choices) and partner with sustainability initiatives to reduce environmental footprint.
Author technical reports and present formulation rationales and trial outcomes to internal stakeholders and external customers, translating complex technical data into actionable recommendations.
Monitor key performance metrics (first-pass color accuracy, print waste, press downtime related to ink issues) and implement continuous improvement projects to reduce costs and improve on-press performance.
Ensure laboratory and pilot production compliance with quality systems (ISO, GMP or customer-specific QMS) and participate in internal and supplier audits as required.
Provide customer-facing technical support and root-cause analysis during warranty or quality disputes; offer remedial actions, corrective formulations, and mitigation plans.
Manage inventory of lab chemicals, pigments and bench stocks with attention to hazardous material handling, labeling and regulatory storage requirements.

Secondary Functions

Support business development by providing technical input for proposals, samples and proofs-of-concept to prospective customers and brand owners.
Perform ad-hoc analytical testing (FTIR, GC, HPLC, gloss meters, rub tests) or coordinate with external labs for advanced analysis when needed.
Contribute to cross-functional R&D roadmaps, aligning ink development timelines with product launches and packaging innovation initiatives.
Participate in continuous improvement initiatives such as 5S, Kaizen events and production waste reduction projects related to inks and pigments.
Serve as a subject-matter expert (SME) in safety committee meetings for handling solvents and reactive chemistries.
Mentor junior chemists and lab staff in good laboratory practices, documentation standards and safe operation of milling/dispersing equipment.
