Flexographic printing (often called flexo printing) is the dominant printing process for labels and packaging. From supermarket food pouches and beverage cartons to corrugated boxes and shrink sleeves, flexography combines high‑speed production with versatility and increasingly high print quality. As the packaging industry embraces sustainability and digital transformation, the flexo landscape in 2026 is evolving rapidly. This guide dives deep into what flexo printing is, how it works, where it excels, and how modern technologies such as extended gamut printing, HD Flexo plates, UV‑LED curing, AI‑driven automation and hybrid digital presses are shaping its future.
As a company specialized in flexographic prepress automation, AV Flexologic offers unique insights into flexo printing. AV Flexologic introduced the first automated plate mounting system more than 20 years ago and continues to lead the industry with innovations such as the SAMM 3.0 automatic mounter, the FAMM 3.0 fully automatic mounter, the RoboCELL suite for robotic sleeve handling and taping, and the EXACT automated laser cutting & engraving system. These solutions combine vision‑based alignment, motorized plate application and AI‑driven image recognition to deliver micron‑level precision and repeatable workflows. Throughout this article, we will highlight how these technologies enable the core flexo processes explained below.
History and evolution of flexographic printing
Flexography traces its origins to the late 19th century. The first rotary printing press using rubber relief plates was patented in 1890, and early machines employed aniline dyes, giving rise to the term aniline printing. As the process evolved, manufacturers introduced anilox rollers to meter ink precisely and flexible photopolymer plates that could wrap around cylinders. To distance the process from toxic aniline inks, the industry adopted the name flexography in 1952. Today flexo printing uses advanced photopolymer plates, ceramic‑coated anilox rolls, water‑based or UV‑curable inks and automated presses that can print, die‑cut, fold and glue in a single pass.
How flexographic printing works
Flexography is a direct rotary printing process. Flexible relief plates mounted on cylinders transfer ink directly onto a substrate under light pressure (“kiss printing”).
The process involves several key components:
Anilox roller – a steel or aluminium cylinder coated with ceramic and engraved with thousands of microscopic cells. Ink fills these cells and a doctor blade wipes excess ink, leaving a precise volume in each cell. Cell geometry (line count, volume and engraving angle) determines ink transfer and print density.
Inking system – ink is pumped either through a two‑roller system or an enclosed chamber that feeds the anilox roll.
Photopolymer plate – made via analog or digital computer‑to‑plate (CTP) processes. Digital CTP uses laser ablation to remove a black mask, exposing the plate’s relief image and providing higher precision and shorter preparation times than analog film methods. Plates are mounted onto cylinders using adhesive tape.
Plate cylinder and impression cylinder – the flexible plate on the plate cylinder transfers ink to the substrate as it rotates against the impression cylinder.
Substrate transport and drying – the material (paper, film, foil, etc.) unwinds from a roll, passes through each color station, is dried or cured (via hot air, IR, UV or electron beam) and rewinds. Modern presses integrate web guiding, tension control, inspection, die‑cutting and finishing.
Accurate plate mounting is the foundation of high‑quality flexo printing: misaligned plates can cause registration errors, color shifts and waste. Our automatic mounters address this challenge by using vision‑based alignment and motorized plate application to achieve micron‑level precision while reducing operator involvement. Automation shortens make‑ready times from around 10 minutes per sleeve to under 2 minutes, reduces waste and enables repeatable workflows. These innovations demonstrate how our equipment enhances the core printing process described above.
The process is modular: each color station contains its own anilox, inking system, plate and impression cylinder, allowing multi‑color prints.
Flexographic press configurations
Inline presses – each color station is arranged horizontally. They are versatile for multiple processes (printing, varnishing, die‑cutting) and common in narrow‑web label production.
Stack presses – color decks are stacked vertically. They handle a wide range of substrates and thicknesses and are common for paper or film packaging.
Central impression (CI) presses – multiple plate cylinders surround a central impression cylinder. CI presses offer superior registration, making them ideal for high‑speed flexible packaging and films.
Corrugated (post‑print) presses – built for printing directly onto corrugated board; they accommodate thick substrates and integrate die‑cutting.
Flexo inks and substrates
Water‑based inks – favoured for paper and corrugated board because they are low‑VOC and align with environmental regulations. Studies report that water‑based inks can reduce carbon footprint by 30–40 % compared with solvent‑based inks and achieve comparable print quality. Stable viscosity delivers 20–30 % higher performance and extends plate life.
Solvent‑based inks – used when printing on films and foils requiring strong adhesion. They dry quickly but generate VOC emissions.
UV‑curable inks – cure instantly under ultraviolet light. UV‑LED curing can reduce energy consumption by 70 % compared with mercury lamps and eliminates VOC emissions; it also enables printing on heat‑sensitive films and delivers vibrant colours and crisp details.
Electron‑beam (EB) inks – cured by electron beams, offering low migration and eliminating photoinitiators.
Because flexo uses flexible plates and low‑pressure printing, it prints on both porous (paper, tissue, corrugated board) and non‑porous substrates (polyethylene, polypropylene, PET, PVC films, aluminium foils, laminates, adhesive labels and fabrics). This substrate versatility underpins its dominance in flexible packaging, labels, shrink sleeves, cartons, corrugated boxes and specialty applications.
Step‑by‑step flexographic printing workflow
Plate making – digital artwork is separated into colour channels and output to photopolymer plates via CTP. Plates are washed, dried and finished, then mounted onto plate cylinders with adhesive tape.
Ink metering – ink is pumped from the ink pan or chamber to the anilox roller. The doctor blade removes excess ink so each cell holds a precise volume.
Ink transfer – the rotating anilox roll transfers ink to the raised areas of the plate. Only the raised image receives ink, ensuring clean edges.
Printing – as the substrate passes between the plate and impression cylinders, the inked plate lightly “kisses” the substrate, transferring the image.
Drying/curing – printed material moves through a dryer (hot air, IR) or UV/EB curing unit. UV‑LED curing eliminates VOCs and reduces energy consumption.
Converting and finishing – inline processes such as varnishing, cold‑foil stamping, lamination, die‑cutting, folding and gluing can be integrated. Finally, the material rewinds for further converting or shipping.
Advantages and disadvantages of flexographic printing
Advantages
High speed and efficiency – continuous roll‑to‑roll printing with quick drying achieves production speeds exceeding 200–300 m/min. Modern CI presses deliver high registration accuracy and minimal waste.
Versatility of substrates – prints on paper, film, foil, label stock, tissue, corrugated board and more.
Cost‑effective for long runs – durable photopolymer plates and efficient ink transfer make flexography economical for high‑volume packaging and labels. Reusable plates reduce per‑unit cost for repeat jobs.
Wide range of inks – water‑based, solvent‑based, UV‑curable and EB inks enable printing on diverse materials and support regulatory compliance. UV‑LED curing reduces energy consumption and VOCs.
Integration of in‑line processes – printing, die‑cutting, varnishing and gluing can occur in a single pass, reducing handling and lead time.
Improving print quality – high‑definition plates, anilox engravings and digital prepress have elevated flexo quality to rival offset and gravure printing. HD Flexo technology with Flat‑Top‑Dot plates yields exceptional detail and smooth gradients; new plate materials reduce flute marks on corrugated board.
Disadvantages
Setup time – changing plates and ink requires preparation. Although automation reduces make‑ready times, flexo still involves longer setup than digital printing, making it less economical for very short runs.
Fine detail limitations – while high‑definition plates have narrowed the gap, gravure and digital printing can still achieve finer details and photographic quality on certain substrates.
Initial investment – presses, anilox rollers and plate making equipment require significant capital expenditure. Smaller converters may face challenges due to raw material price volatility and higher per‑unit costs.
