Printing and Coating Touch Everything You Buy
Pick up any product in a grocery store, a pharmacy, or a hardware store. The label on the bottle, the graphics on the cereal box, the metallic finish on a cosmetics package, the anti-counterfeiting hologram on a pharmaceutical blister pack -- every one of those visual elements was produced on an automated printing or coating line. The global printing industry generates over $420 billion annually, while industrial coatings (automotive, aerospace, architectural, protective, packaging) add another $180 billion. Combined, printing and coating automation represents a $600 billion sector that employs hundreds of thousands of skilled tradespeople who maintain the presses, coaters, dryers, and inspection systems that produce the surfaces we interact with every day. Despite its massive economic footprint, printing and coating automation flies under the radar of most career counselors -- which is exactly why the experienced professionals who run these systems command premium compensation.
The printing industry is in the middle of a technological shift that is creating acute demand for automation-savvy professionals. Traditional analog printing processes -- offset lithography, flexography, gravure, screen printing -- are being augmented and in some cases replaced by digital inkjet and electrophotographic systems that require fundamentally different skill sets. A press operator who spent 20 years mastering the color management, registration control, and mechanical adjustment of a flexographic press may not have the electrical, software, and networking skills needed to maintain a digital inkjet press from HP Indigo, Heidelberg, Koenig & Bauer, or Bobst. The industry needs professionals who can bridge both worlds -- understanding the physics of ink transfer, drying, and adhesion while also programming servo drives, vision systems, and network-connected production management systems.
Web Press Automation: Flexography and Gravure
Web printing -- continuous roll-to-roll printing at speeds up to 3,000 feet per minute -- is the backbone of packaging, label, and publication production. Flexographic printing uses flexible photopolymer plates mounted on impression cylinders to transfer ink to substrates ranging from paper and corrugated board to polyethylene film and aluminum foil. Modern flexographic presses from BOBST, Windmoller & Holscher, PCMC, Mark Andy, and Nilpeter are highly automated machines with servo-driven impression, register, and tension control. Registration -- maintaining alignment between multiple print colors to within 0.1 mm at full speed -- requires closed-loop servo systems using web inspection cameras from BST eltromat, AVT (Advanced Vision Technology), and ISRA VISION that detect print-to-print and print-to-cut registration errors and feed corrections to the drive system in real time.
Gravure printing uses engraved copper cylinders to carry ink in etched cells, producing the highest quality reproduction for long-run packaging, decorative laminates, and publication printing. Gravure presses from Bobst, Cerutti (now Bobst), and Windmoller & Holscher operate at speeds up to 2,500 feet per minute with doctor blade systems that meter ink from the engraved cells with micron-level precision. Electrostatic assist (ESA) systems improve ink transfer to porous substrates. Cylinder handling automation -- loading, mounting, and positioning engraved cylinders weighing hundreds of pounds -- uses robotic systems and automated storage systems to minimize changeover time. Press operators transitioning to automation roles need to understand not just the printing process but the servo drives (Siemens, Bosch Rexroth, Rockwell), the HMI/SCADA systems (Siemens WinCC, Rockwell FactoryTalk), and the web inspection platforms that make modern presses function.
Coating and Converting Automation
Industrial coating lines apply functional and decorative coatings to substrates ranging from steel coils (automotive body panels, appliance surfaces, building products) to glass (architectural, automotive, solar panels), plastic film (barrier coatings for food packaging), and wood products (furniture, flooring, cabinetry). Automotive coating lines are among the most complex automation installations in manufacturing -- a single automotive paint shop contains 30 to 50 robots applying primer, basecoat, and clearcoat in environmentally controlled booths, with ovens, wash stations, and inspection systems coordinated by plant-wide PLC and MES systems. FANUC, ABB, Duerr, and Eisenmann supply robotic painting systems. Nordson, Graco, and Carlisle Fluid Technologies supply pumping, mixing, and applicator equipment for precision coating delivery.
UV and electron beam (EB) curing systems instantly cure coatings, adhesives, and inks using ultraviolet light or electron beams rather than thermal drying. UV/EB curing eliminates solvent emissions, reduces energy consumption by 80 percent compared to thermal drying, and enables production speeds that thermal processes cannot match. Heraeus, IST METZ, GEW, and Prime UV supply UV curing systems, while PCT Ebeam and COMET supply EB curing equipment. The automation professionals who integrate curing systems with coating application must understand photochemistry, lamp/emitter power management, dose measurement, and the safety interlocks required for UV and EB radiation sources.
Web tension control is the common automation thread across all printing and coating operations. Maintaining consistent tension throughout the web path -- from unwind through processing to rewind -- requires load cells, dancers, PID control algorithms, and coordinated drive systems. Dover Flexo Electronics, Montalvo, and Re Controlli supply tension measurement and control systems. Converting operations (slitting, die cutting, laminating, folding, gluing) downstream of printing and coating use motion control systems from Rockwell, Siemens, and Beckhoff to synchronize multiple operations on the same web.
Salary Ranges and Major Employers
Press automation technicians maintaining electrical and control systems on printing presses earn $55,000 to $85,000. Press automation engineers programming servo systems, vision, and registration earn $75,000 to $110,000. Coating line engineers in automotive or specialty coatings earn $80,000 to $120,000. Web inspection systems engineers earn $70,000 to $105,000. Production engineering managers overseeing print and coating operations earn $95,000 to $140,000. Digital press service engineers from OEMs earn $70,000 to $110,000 with travel. Contract rates through Automate America range from $50 to $80 per hour for press maintenance and $70 to $115 per hour for controls engineering and commissioning.
Major packaging printers include WestRock, Graphic Packaging, Sonoco, Berry Global, Amcor, and Sealed Air. Label converters include CCL Industries, Multi-Color (now CLONDALKIN), Fort Dearborn, and Avery Dennison. Automotive coating operations exist at every vehicle assembly plant -- Ford, GM, Stellantis, Toyota, Honda, Tesla, BMW, Mercedes, Hyundai-Kia. Coil coating operations run at steel mills and independent coaters like AkzoNobel, PPG, Sherwin-Williams, and Axalta. Press manufacturers including BOBST, Heidelberg, Koenig & Bauer, PCMC, Mark Andy, and HP Indigo employ field service engineers. Geographic concentrations follow consumer products manufacturing -- the Midwest (packaging for food, beverage, consumer goods), the Southeast (automotive paint shops), and metro areas nationwide (commercial and label printing).
Training and Getting Started
The Flexographic Technical Association (FTA) offers certification programs and educational resources. The FIRST (Flexographic Image Reproduction Specifications and Tolerances) program establishes print quality standards used industry-wide. Clemson University's Sonoco Institute of Packaging Design and Graphics operates a research flexo press and offers courses in print process engineering. Cal Poly San Luis Obispo, Rochester Institute of Technology (RIT), and the University of Wisconsin-Stout offer graphic communications programs that cover both traditional and digital printing technology. TAPPI (Technical Association of the Pulp and Paper Industry) offers courses in coating and converting technology. Equipment-specific training from Siemens (for servo systems), Rockwell Automation (for PLC and drive systems), and BST eltromat (for web inspection) provides the controls engineering skills that complement press and coating process knowledge. Apprenticeships through the Graphic Communications Conference (GCC-IBT) union provide structured training paths in pressrooms.
