Core Responsibilities

Primary Functions

Set up, calibrate, and operate printing presses (flexographic, rotary screen, gravure, offset) to meet production schedules, ensuring accurate plate/cylinder installation, web tensioning, and registration control for consistent print quality.
Prepare, mix and adjust inks by following formulas and batch records, accurately measuring pigments, solvents, binders, and additives to achieve target color and viscosity specifications.
Perform precise color matching using spectrophotometers, colorimeters, density meters, and production proofing methods to meet customer color standards (Pantone/Lab values) and maintain color consistency across runs.
Monitor ink viscosity, tack, pH, and other chemical properties during production, making real-time adjustments to maintain printability, dot gain control, and adhesion on various substrates (film, paper, foil).
Conduct press start-up and shut-down procedures, including purging ink systems, cleaning anilox rolls, doctor blades, screens, and squeegees to prevent contamination and ensure product quality.
Execute routine and preventative maintenance on ink delivery systems, pumps, dampening systems, heaters, chillers, and associated press components, logging maintenance actions and coordinating repairs with maintenance teams.
Troubleshoot press defects such as streaks, ghosting, set-off, mottling, color shift, banding, and registration errors by diagnosing root causes and implementing corrective actions to minimize downtime and waste.
Load and change printing plates, cylinders, sleeves, and doctor blade holders, ensuring correct orientation, tensioning and securing to manufacturer and SOP specifications for repeatable production runs.
Verify substrate compatibility, perform substrate tests (adhesion, rub resistance, ink transfer), and select appropriate primer and coating options to ensure finished product durability and performance.
Maintain accurate production documentation including batch ink records, production logs, run tickets, lot traceability, ink lot numbers, and quality control checklists for regulatory compliance and customer audits.
Conduct inline and end-of-run quality inspections, measuring color density, dot gain, gloss, registration, and print dimensions; isolate and reject defective material and document non-conformances.
Manage ink inventory and supplies, reorder stock, rotate chemical lots, label containers with SDS compliance, and ensure availability of pigments, solvents, additives, and coatings to support continuous production.
Follow environmental, health and safety protocols for handling, storing, transporting, and disposing of inks, solvents and hazardous waste, including proper use of personal protective equipment (PPE) and adherence to MSDS/SDS guidance.
Optimize press run parameters—speed, anilox selection, impression, drying/curing settings (IR/UV/Hot Air)—to maximize throughput while maintaining print quality and minimizing substrate waste.
Provide hands-on training and mentoring to junior pressroom staff and helpers on ink mixing, basic color theory, press operation, and safe handling of chemical materials to build team competence.
Collaborate with prepress, production planning, and quality assurance to interpret customer specifications, proof approvals, and change requests, ensuring deliverables meet contract and artwork requirements.
Conduct root cause analysis for recurring print issues and participate in continuous improvement initiatives (5S, Kaizen, SPC) to reduce waste, improve OEE, and standardize best practices across shifts.
Operate and maintain curing systems (UV LED, mercury vapor) and drying ovens, adjusting dwell time and lamp intensity for optimal ink cure, adhesion, and scratch resistance on different materials.
Perform emergency response actions for spills, leaks, and equipment malfunctions, following containment procedures and notifying supervisors, safety, and environmental teams as required.
Execute color correction and final color proof sign-off processes for customer approvals, making controlled recipe adjustments and documenting approvals for production runs.
Support packaging, slitting, rewinding, and finishing operations by ensuring print quality is maintained through subsequent converting processes and communicating defects to finishing teams.
Participate in shift handovers by delivering comprehensive run reports, unresolved issues, and corrective actions to incoming operators to maintain continuity and reduce repeat defects.
Maintain clean and organized pressroom workspaces, complying with 5S standards and improving accessibility to tools, spare parts, and cleaning supplies.
Ensure compliance with company quality systems (ISO, G7, customer-specific standards) by following documented procedures, completing required records, and cooperating with internal and external audits.

Secondary Functions

Assist production planners with scheduling input and run-time estimates based on ink changeover and setup complexity to improve throughput planning.
Support product development and R&D teams during trials by sampling new ink formulations, substrates, and process settings and documenting results.
Help maintain and update standard operating procedures (SOPs) and ink recipes in the manufacturing knowledge base for reproducible results across shifts.
Participate in safety committees and continuous improvement teams to propose process improvements, waste reduction ideas, and ergonomics enhancements in the pressroom.
Provide technical input to procurement around preferred ink brands, supplier performance, and alternative raw materials to mitigate supply risks.
Support quality assurance by providing on-demand samples for laboratory testing, assisting with corrective action investigations, and implementing approved changes.
