What they are
Textured coatings are speciality varnishes or UV coatings containing particles or additives that create a physical texture on the printed surface, visible and tangible under the fingertip. Unlike embossing (which mechanically deforms the substrate) or soft-touch lamination (which adds a film), textured coatings are applied as a liquid coating and cure to their textured state in place.
Types of textured coatings
| Texture type | How it is created | Tactile feel | Applications |
|---|---|---|---|
| Sand / grit texture | Fine silica or mineral particles mixed into UV varnish. Applied by screen printing or coating unit. | Rough, granular, like fine sandpaper | Premium packaging, masculine fragrance brands, industrial tools packaging |
| Velvet / suede texture | Fine polymer microspheres in UV coating base. Applied by coating unit. | Extremely soft, velvety, similar to soft-touch lamination but applied as a coating rather than a film | Luxury cosmetics, premium perfume packaging, high-end book covers |
| Linen / fabric texture | Linen pattern embossed into the wet UV coating as it cures, or a coating with woven texture particles | Textile-like, parallel raised ridges | Premium stationery, corporate gifts, premium food packaging |
| Leather grain texture | Leather pattern embossed into UV coating | Fine irregular grain, leathery | Premium stationery, luxury packaging, corporate gifts |
| Crinkle / wrinkle texture | UV coating applied thickly then cured rapidly, creating contraction wrinkle pattern | Irregular crinkled surface | Industrial and automotive packaging, tool packaging |
Application methods
Screen printing unit: The textured coating is applied through a screen with an open mesh across the entire area to be coated. The screen deposits a thick, even layer of coating that retains the texture particles. Best for spot textured coating on specific design areas.
Coating unit (inline or offline): A roller-based coating unit applies the textured coating across the entire sheet or in specific zones. More consistent for large areas. Less suited to very small spot applications.
Combining textured coating with other finishing
Textured coatings are most effective when combined with contrasting finishing in adjacent areas. The classic combination: velvet or sand texture in the background, with a foil-stamped logo or title element on top, the contrast between rough texture and mirror-bright foil is a premium finishing signature used extensively in luxury cosmetics and fragrance packaging.
Textured coatings are available from premium finishing facilities in Mumbai, Delhi, and Bengaluru. The luxury cosmetics and personal care segment (premium ayurvedic brands, domestic luxury fragrances, premium haircare packaging) and the corporate gifting sector are the primary users in India. Sand texture coating is particularly popular for masculine-positioned brands (whisky, men's grooming) where the rough texture signals robustness.
How cold foil differs from hot foil
Hot foil stamping uses a heated metal die pressed against foil under high pressure, the heat activates the foil adhesive and transfers the metallic layer to the substrate. Cold foil uses a UV-curable adhesive instead: the adhesive is printed onto the substrate by an offset printing unit, the foil roll is pressed against the adhesive-coated area, and the adhesive is immediately cured by UV light, bonding the foil without any heat. The foil adheres only where the adhesive was printed.
- Applied inline on press, no separate foil stamping run
- Fine halftone and gradient foil possible (adhesive can be screened)
- No die cost, adhesive plate is a standard offset plate
- Lower setup cost for short runs
- Very fine detail achievable
- Brighter, more intense foil finish
- Works on a wider range of substrates
- More reliable adhesion on rough or textured substrates
- More economical for large foil areas at high volume
- Embossing can be combined in the same hit
Cold foil and overprinting
One significant capability of cold foil is that CMYK colours can be overprinted on top of the applied foil in subsequent printing units, creating coloured metallic effects (red foil, blue foil, two-tone metallic) that would require multiple hot foil dies to achieve by the conventional method. The foil base reflects the overprinted CMYK colours, producing rich tonal metallic results.
Design considerations
- The foil adhesive plate is made as a standard offset plate, any printable design can be foiled, including photographic halftones
- Minimum feature size is finer than hot foil, 0.3mm lines are achievable in cold foil vs 0.5mm in hot foil
- Cold foil requires a UV-equipped press with an inline foil unit, not all presses have this capability
- The foil finish is slightly less bright than hot foil, for maximum brilliance, hot foil remains the standard
Cold foil equipment is available at larger commercial and packaging printers in Mumbai and Delhi who have invested in UV-equipped offset presses with inline cold foil units. It is used primarily for premium FMCG packaging, label printing, and cosmetics packaging where foil gradient effects or combined foil-and-process-colour results are required. Cold foil is less universally available than hot foil stamping in India, confirm capability with your press room before specifying.
What digital cutting is
Digital die cutting uses a computer-controlled cutting head, either a sharp blade, router bit, or laser, that follows a digital path file to cut, crease, perforate, or score any shape without a physical cutting die. The cutting path is defined in the design file and sent directly to the cutter. Every job can have a different shape with zero additional setup cost beyond programming time.
The two market-leading systems are Zünd (Swiss) and Kongsberg (Norwegian). Both are large-format flatbed cutting tables that process sheets up to approximately 3.2m × 2m and handle substrates from 60 GSM paper through to 25mm acrylic, foam board, corrugated, fabric, and leather.
Digital cutting vs conventional die cutting
| Factor | Digital cutting (Zünd/Kongsberg) | Conventional die cutting |
|---|---|---|
| Tooling cost | Zero, cutting path is a digital file | ₹3,000–25,000+ per cutting die depending on complexity |
| Setup time | Minutes, load file and run | Days for die manufacture, then make-ready |
| Minimum quantity | 1 piece | 200–500 pieces to amortise die cost |
| Speed at high volume | Slower than press die cutting | Faster, 3,000–10,000+ pieces per hour |
| Shape accuracy | ±0.1–0.3mm | ±0.3–0.5mm (die wear over run) |
| Design changes | Instant, change digital file | New die required, cost and lead time |
| Substrate range | Very wide, paper to 25mm rigid boards | Limited to the material the die is designed for |
What digital cutting enables that conventional die cutting cannot
- Personalised shapes: Every piece in a run can have a different shape, name cards cut to individual profile shapes, packaging with variable cutouts
- Prototyping: Produce one sample of a packaging structure before committing to die tooling investment, changes cost nothing except time
- Short run intricate shapes: Complex carton structures, exhibition display components, and point-of-sale displays that would not be economical with conventional dies at short quantities
- Laser cutting on digital cutters: Some Zünd and Kongsberg systems have laser cutting heads that can cut very intricate patterns (jali-style decorative cuts) without mechanical tool contact, eliminating compression on delicate materials
Zünd and Kongsberg digital cutters are available at commercial print and packaging facilities in Mumbai, Delhi, Bengaluru, and Hyderabad. They are used for premium packaging prototyping and short-run production, point-of-sale display manufacture, exhibition display components, architectural model making, and personalised stationery and gifts. The prototyping application is particularly valuable, Indian packaging designers can now produce physical carton and display samples within hours rather than waiting days for conventional die manufacture.
What Braille printing is in the context of packaging
Braille is the tactile writing system used by visually impaired people, a grid of raised dots representing letters, numbers, and punctuation. On pharmaceutical and healthcare packaging, Braille embossing identifies the product name for visually impaired patients, enabling them to distinguish between medicines independently.
Regulatory requirements
European Union: The EU Directive 2004/27/EC (as part of the EU Pharmaceutical Directive) has required Braille on all prescription medicine packaging since 2010. The product name must be in Braille on the outer packaging. This is mandatory for all medicines sold in EU markets, not optional.
India: Braille on pharmaceutical packaging is not currently mandatory in India under CDSCO (Central Drugs Standard Control Organisation) regulations. However, Indian pharmaceutical companies exporting to EU markets must include Braille on EU-destined packaging. Several Indian companies voluntarily include Braille on domestic packaging as part of accessibility commitments.
Technical specifications for pharmaceutical Braille
EU guidance specifies precise dimensional requirements for pharmaceutical Braille:
| Parameter | Specification |
|---|---|
| Dot height (above surface) | Minimum 0.2mm, recommended 0.4mm |
| Dot base diameter | 1.5mm (±0.1mm) |
| Dot-to-dot spacing (within cell) | 2.5mm centre to centre |
| Cell-to-cell spacing (horizontal) | 6.0mm centre to centre |
| Line-to-line spacing | 10.0mm centre to centre |
How Braille is applied to pharmaceutical cartons
Embossing (most common): A Braille embossing die presses raised dots into the carton board. The die contains the pattern of pins corresponding to the Braille text. Applied inline on the packaging production line or offline. Requires a minimum board thickness (typically 300 GSM or above) to hold the embossed dots without the board cracking or collapsing under folding.
UV inkjet Braille (emerging): UV inkjet printing can deposit thick UV-curable ink in dot patterns that cure to form raised Braille dots. No embossing die required, the pattern is digital. Height is controlled by the number of ink layers deposited. Increasingly used for short-run and export-variant packaging where creating embossing dies for small quantities is not economical.
Braille is not a simple letter-for-letter transcription. Pharmaceutical Braille uses Grade 1 Braille (uncontracted, every letter spelled out) for maximum clarity and safety. Always use a qualified Braille translator or a validated pharmaceutical Braille translation service to produce the Braille text file. Never generate Braille content from an unvalidated online converter for pharmaceutical use, a transcription error could cause a patient to misidentify their medication.
India's pharmaceutical export sector, supplying EU and US markets, has driven adoption of Braille embossing in Indian carton manufacturing. Packaging converters in Hyderabad, Ahmedabad, and Mumbai who supply the export pharma sector have invested in Braille embossing tooling and validation processes. The domestic Indian market does not currently mandate Braille, but with India being the world's pharmacy and serving regulated markets that do mandate it, the capability is widely established in the export-oriented segment.
What shrink wrapping is in a finishing context
Shrink wrapping (also called shrink film overwrapping or cellophane wrapping) is a finishing process where a loose product, a book, a box set, a set of greeting cards, a bundle of brochures, is enclosed in a clear plastic film that is then heat-shrunk to form a tight, transparent outer package. This is distinct from shrink sleeve labels (which decorate containers), shrink wrapping is about enclosing a finished product for protection, tamper evidence, and retail presentation.
How it works
The product is placed in a pre-formed shrink film bag or wrapped in film on an L-bar sealer (which cuts and seals the film around the product simultaneously). The wrapped product then passes through a heat tunnel at approximately 120–180°C depending on the film type. The heat causes the film to shrink uniformly around the product, conforming tightly to its shape and sealing the package.
Film types for shrink wrapping
| Film | Clarity | Shrink rate | Applications |
|---|---|---|---|
| POF (Polyolefin) | Excellent, crystal clear | 40–60% | Books, stationery, gift sets, food products, preferred for most commercial shrink wrapping |
| PVC (Polyvinyl chloride) | Good | 40–60% | Economy applications, shrinks well but releases chlorine compounds during heat tunnel (ventilation required) |
| Polyethylene (PE) | Moderate (slightly hazy) | 15–30% | Bundle packaging, pallet overwrap, industrial |
Applications in print finishing
- Books: Shrink-wrapped books at the point of sale protect against handling damage and signal an "as new" condition. Common for coffee table books, photography books, and gift editions.
- Stationery and card sets: Greeting card sets, notecards, and premium stationery packs are shrink-wrapped to keep components together and prevent pilferage at retail.
- Calendars: Most printed calendars are delivered shrink-wrapped for retail display and protection during distribution.
- DVD/Blu-ray style packaging: Multi-component boxes, annual report boxes, and gift sets are shrink-wrapped to present the complete package as a unit.
- Bundle packaging: Multiple identical printed items bundled together for trade distribution, shrink wrapping replaces rubber bands or box packaging at lower cost.
Shrink wrapping is a standard capability at most commercial finishing houses in India. Calendar manufacturers in Sivakasi, Mumbai, and Delhi routinely shrink-wrap finished calendars before distribution. Book publishers use shrink wrapping for gift editions and export copies. POF film is the standard for commercial print finishing applications; PVC is used for economy bulk packaging. Automated L-bar sealers and heat tunnels are available at medium and large finishing facilities nationally.
When to Specify Each Specialty Finish
| Application | Finishing choice | Why |
|---|---|---|
| Premium perfume or cosmetics carton | Velvet coating + spot foil | Tactile luxury signal, velvet background with foil logo creates premium contrast |
| Metallic foil on detailed design with gradients | Cold foil (inline) | Only process that can produce foil halftone, hot foil cannot reproduce gradient foil areas |
| Packaging prototype before die investment | Digital cutting (Zünd) | Zero tooling cost, same-day sample, validate structure before committing to die |
| Pharmaceutical carton for EU export | Braille embossing | EU Directive 2004/27/EC mandatory requirement |
| Book or calendar retail packaging | POF shrink wrap | Protection, tamper evidence, clean retail presentation |
| Short-run intricate carton structure | Digital cutting | Die would cost more than the entire print run, digital cutting makes short run viable |
| Sand texture on spirits or men's grooming packaging | Sand/grit textured coating | Tactile surface communicates robustness and premium positioning for masculine brands |
| Personalised stationery with individual shapes | Digital cutting with variable data | Each piece can be a different shape, impossible with conventional dies |
