Gravure Ink: What It Is, Types, Formulation & How Gravure Printing Works (2026)
Last Updated:Last updated: September 25, 2026.
Quick answer: Gravure ink is a thin, fast-drying liquid ink made for gravure (rotogravure) printing, where the image is engraved as tiny cells into a metal cylinder. The low viscosity lets the ink flood those cells, a steel doctor blade wipes the surface clean, and the ink left in the cells transfers straight onto film, foil, paper or board. Gravure inks are solvent-based, water-based, or (less often) energy-curable, and are built from pigment, resin binder, solvent and additives.
Gravure is the process behind most of the printed snack bags, candy wrappers, labels, wallpaper and laminate flooring you see every day. The ink is what makes it work at speeds of well over 1,000 feet per minute. This guide answers the most common questions about gravure ink in 2026: what it's made of, the main types, how viscosity and filtration are controlled on press, who makes it, and how it compares with flexo and offset inks.
What Is Gravure Ink?
Gravure ink is a low-viscosity liquid ink designed for intaglio cylinder printing. Unlike the paste inks used in offset lithography, gravure ink is almost as thin as water so it can fill microscopic engraved cells and release cleanly in a fraction of a second. It must then dry almost instantly, before the web reaches the next print unit, which is why most gravure inks rely on fast-evaporating solvents and powerful dryers between stations.
How Does Gravure Printing Work?
Gravure is an intaglio process: the image sits below the surface of the printing cylinder rather than on top of it. A typical rotogravure unit works like this:
- Engraved cylinder. A steel or aluminum base is copper-plated, electronically or laser engraved with millions of tiny cells, then chrome-plated for wear resistance. Deeper or larger cells hold more ink and print darker tones.
- Inking. The cylinder rotates through an ink pan (or is fed by an enclosed ink chamber) and every cell fills with ink.
- Doctor blade. A thin flexible steel blade scrapes excess ink off the non-image surface, leaving ink only in the cells.
- Impression. A rubber-covered impression roller presses the substrate against the cylinder, and ink transfers directly from the cells to the web.
- Drying. Hot-air dryers after each unit evaporate the solvent or water so the next color can print without smearing. Solvent-laden exhaust is usually sent to solvent recovery or an oxidizer.
A press has one unit per color, commonly 8 to 10 units for packaging, plus stations for whites, metallics, varnishes or coatings.
What Are the Main Types of Gravure Ink?
| Type | Carrier | Typical uses | Pros | Trade-offs |
|---|---|---|---|---|
| Solvent-based | Ethyl acetate, alcohols (ethanol, n-propanol), ketones; toluene in older publication work | Flexible packaging, publication, labels, shrink sleeves | Very fast drying, excellent adhesion to plastic films, top print quality at high speed | VOC emissions require recovery or incineration; flammable |
| Water-based | Water with small amounts of alcohol/amines | Paper and board packaging, gift wrap, wallcoverings, some films | Low VOC, safer handling, easier compliance | Slower drying, more dryer energy, harder to run at top speeds and on non-porous films |
| Energy-curable (UV/EB) | Monomers and oligomers cured by UV light or electron beam | Specialty packaging, décor, high-resistance coatings | Near-zero VOC, instant cure, high rub and chemical resistance | Higher ink and equipment cost; low-migration formulations needed for food packaging |
Within those families, inks are further specified by application: surface-print inks (printed on the outside of a package) versus lamination inks (reverse-printed and sealed between film layers), heat-resistant and retort-resistant inks, and low-migration inks for food contact packaging.
What Is Gravure Ink Made Of? (Formulation)
Every gravure ink has four building blocks:
- Colorant (about 5–20%). Organic or inorganic pigments that provide color. Metallic inks use aluminum or bronze flakes; whites use titanium dioxide.
- Binder/resin (about 10–25%). Forms the dried ink film and determines adhesion, gloss and resistance. Common gravure resins include nitrocellulose, polyurethane, polyamide, vinyl, acrylic and rosin-modified resins, chosen to match the substrate.
- Solvent or water (about 50–75%). Carries the pigment and resin into the cells, then evaporates. The solvent blend is tuned for drying speed.
- Additives (a few percent). Waxes for slip and scuff resistance, plasticizers for flexibility, adhesion promoters, defoamers, and dispersants that keep pigment evenly suspended.
Formulators balance these to hit a target viscosity, drying speed, color strength and adhesion for a specific press, cylinder engraving and substrate.
How Is Gravure Ink Manufactured?
Ink makers first pre-mix pigment with resin and solvent, then grind the mix in a bead mill so pigment particles are finely and evenly dispersed. This concentrated base is let down with more resin, solvent and additives, tested for color, strength and viscosity, filtered, and shipped either as press-ready ink or as concentrates and varnish that the printer blends on site. Many converters now run in-house ink kitchens with color-matching software to mix spot colors and reuse returned ink.
What Viscosity Should Gravure Ink Be?
Gravure press inks typically run at roughly 15 to 30 seconds on a Zahn #2 or Shell #2 efflux cup, far thinner than flexo or offset inks. The exact target depends on the cylinder engraving, press speed and substrate. Ink is delivered thicker and "cut" with solvent at the press.
What Is a Gravure Ink Control System?
Because solvent evaporates constantly from the ink pan, viscosity drifts upward during a run and color shifts with it. A gravure ink control (viscosity control) system measures viscosity continuously with an in-line sensor and automatically meters in solvent to hold it at the setpoint. Many systems also control ink temperature, and circulate ink through enclosed chambers to cut evaporation. The payoff is consistent color from the first roll to the last and lower solvent use.
Why Do Gravure Presses Use Ink Filters?
Gravure ink filters remove dried ink skins, pigment agglomerates, paper dust and metal particles from the circulating ink. Those contaminants can lodge under the doctor blade and cause streaks ("doctor blade lines"), score the chrome cylinder surface, or plug engraved cells. Presses typically use bag, cartridge or magnetic filters in the ink return line, sized to the ink and cell dimensions.
What Is Gravure Printing Used For?
- Flexible packaging: snack and candy bags, coffee pouches, pet food, frozen food, lidding films
- Labels and shrink sleeves: beverage and personal-care labels
- Folding cartons: cigarette and premium cartons
- Décor ("product gravure"): wallpaper, laminate flooring, furniture laminates, paneling, gift wrap
- Publication: long-run magazines, catalogs and inserts (a shrinking share as print volumes fall)
- Security and specialty: stamps, banknote features, heat-transfer papers for textiles
Gravure vs. Flexo vs. Offset: Which Ink and Process Is Best?
| Gravure | Flexography | Offset lithography | |
|---|---|---|---|
| Image carrier | Engraved metal cylinder (image recessed) | Flexible photopolymer plate (image raised) | Flat aluminum plate (image and non-image on the same level) |
| Ink | Very thin liquid | Thin liquid | Thick paste |
| Up-front cost | Highest (cylinders cost hundreds to thousands of dollars each) | Moderate | Low (plates are inexpensive) |
| Best for | Very long runs, consistent premium color, films | Short to long packaging runs, labels, corrugated | Commercial print, books, cartons on paper and board |
| Durability of image carrier | Millions of impressions | Hundreds of thousands | Tens to hundreds of thousands |
Gravure wins on consistency and image quality over very long runs; flexo has taken share in packaging because plates are cheaper and faster to make; offset dominates on paper where runs are shorter.
Who Makes Gravure Ink?
The major global gravure ink manufacturers include Sun Chemical (part of DIC), Siegwerk, Flint Group, Toyo Ink, Sakata INX and hubergroup, alongside many regional and specialty suppliers. Large converters often buy concentrates from these makers and blend final colors in-house.
What Are the Gravure Ink Trends in 2026?
- Toluene-free and lower-VOC inks: packaging gravure has largely moved to ester/alcohol solvent systems, and water-based gravure keeps gaining ground on paper.
- Low-migration and food-safety compliance: brand owners require inks that meet food-contact guidance such as the Swiss Ordinance and EuPIA guidelines.
- Recyclability: mono-material packaging and de-inkable or wash-off inks are being developed to support recycling rules such as the EU Packaging and Packaging Waste Regulation.
- Energy savings: better dryers, solvent recovery and electron-beam curing reduce energy and emissions per square meter printed.
Gravure Ink FAQs
Is gravure ink the same as flexo ink?
No. Both are thin liquid inks, but gravure ink is usually even thinner and formulated to release from engraved cells under a doctor blade, while flexo ink is transferred by an anilox roll to a raised plate. They are not interchangeable without reformulation.
Why does gravure ink dry so fast?
It uses volatile solvents (or water) that evaporate quickly, and every print unit is followed by a high-velocity hot-air dryer, so the ink is dry before the next color is applied.
Is gravure ink toxic?
Solvent-based gravure inks are flammable and release VOCs, so presses use ventilation, solvent recovery and oxidizers, and operators need proper handling procedures. Inks for food packaging are formulated as low-migration systems and printed on the non-food side or sealed within laminate layers.
Can you use gravure ink in an inkjet or desktop printer?
No. Gravure ink is designed for industrial cylinder presses and would clog an inkjet printhead instantly. Desktop printers need cartridges made for that specific model. If you're looking for ink for a home or office printer, see our find ink by printer directory.
Why is gravure printing expensive to start?
Each color needs its own engraved, chrome-plated cylinder, and gravure presses are large custom machines. That cost is spread across very long runs, which is why gravure is chosen for high-volume jobs.
How long does a gravure cylinder last?
A chrome-plated gravure cylinder can print millions of impressions, and can be re-chromed or re-engraved when it wears, which is a major reason gravure is economical for repeat, high-volume work.
