Introduction

Packaging printing is where design meets manufacturing. A beautiful pack design only becomes real when it is printed accurately on the right material, cut and folded precisely, and delivered ready to fill. Unlike a brochure, a carton or label must also survive filling lines, transport, storage and handling, carry legal information, scan at checkouts and protect the product inside.

For brand owners, understanding the basics of label and carton printing makes it easier to choose the right materials and processes, avoid costly mistakes and get packaging that looks good and works well. This article explains what brand owners should know, drawing on Dsigngo Group’s in-house packaging design and print experience.

Why packaging print quality matters

Packaging is often the deciding factor at the shelf. In research by Ipsos for the Paper and Packaging Board, 72% of consumers said packaging design plays a significant role in their purchase decisions. Poorly printed packaging, with dull colours, misaligned graphics, scuffed surfaces or illegible text, undermines a brand, while consistent, high-quality packaging builds trust.

Packaging print errors are also expensive. Thousands of cartons or labels may need to be scrapped, filling lines may stop and products may miss launch dates or retail deadlines.

Folding cartons

Folding cartons are printed paperboard boxes used for products such as tea, cereals, cosmetics, medicines, confectionery, electronics and gifts.

Board types

Common cartonboard grades include:

• Folding boxboard (FBB), with good stiffness and a bright printing surface, widely used for food and consumer goods.
• Solid bleached board (SBB or SBS), made from bleached virgin fibre, with an excellent surface for premium printing.
• Recycled boards, such as white-lined chipboard, which use recycled fibre and are cost-effective for many products.
• Kraft boards, with a natural brown appearance suited to rustic or eco-focused brands.

The right board depends on the product’s weight, the printing quality needed, food-contact requirements, the brand’s look and budget. Board thickness and weight must suit the carton’s size and the stresses it will face.

How cartons are made

1. Artwork is placed on the dieline, the flat technical drawing of the carton.
2. Sheets are printed, usually by offset for medium and long runs.
3. Coatings, varnishes or lamination are applied as needed.
4. Special finishes, such as foil or embossing, are added.
5. Cartons are die-cut and creased using a cutting die made for that design.
6. Waste board is stripped away.
7. Cartons are folded and glued, where required, and packed flat for delivery.

Carton design considerations

• The dieline must fit the product with suitable tolerances.
• Board grain direction affects folding and strength.
• Text and key graphics must be kept clear of folds, glue areas and cut edges.
• Glue areas must be free of ink or varnish so the glue holds.
• Cartons must run on the customer’s packing equipment, whether manual or automatic.

Labels

Labels are used on bottles, jars, cans, pouches, tubes, boxes and many other containers.

Label types

• Self-adhesive (pressure-sensitive) labels, supplied on rolls for hand or machine application. These are the most common type for many products.
• Wet-glue paper labels, often used on glass bottles and cans at high speeds.
• Sleeves, including shrink sleeves that wrap around the container.
• In-mould labels, which become part of moulded plastic containers.

Label materials

• Paper labels: cost-effective and printable, with coated, uncoated and textured options.
• Film labels such as polypropylene (PP) and polyethylene (PE): durable, water-resistant and suitable for products used in wet or cold conditions.
• Metallised and clear materials for special effects.

The adhesive must also suit the container material, surface, temperature and conditions, such as refrigeration or humidity.

Printing methods for labels

Labels may be printed by different processes:

• Flexographic printing, widely used for roll labels and flexible packaging.
• Offset printing, used for sheet labels and wet-glue labels with high image quality.
• Digital printing, ideal for short runs, many variants and personalisation.

The right method depends on quantity, number of designs, materials and quality requirements.

Food-safe printing

For food packaging, inks, varnishes and adhesives must be suitable for their use. Low-migration inks and coatings are designed to minimise the risk of components transferring into food. Requirements vary by market, and buyers often ask for declarations of compliance from packaging suppliers. Packaging for the European Union must also consider the Packaging and Packaging Waste Regulation, which generally applies from 12 August 2026 and introduces restrictions on certain substances in food-contact packaging.

Barcodes on packaging

Retail barcodes must scan reliably. Good practice includes:

• Using valid GS1 barcode numbers.
• Printing barcodes at the correct size with clear quiet zones.
• Using dark bars on a light background.
• Placing barcodes on flat surfaces, away from folds and seams.
• Orienting bars in the printing direction where possible to reduce distortion.
• Verifying printed barcodes against GS1 requirements. GS1 sets an overall grade of at least 1.5 (grade C) on the ISO/IEC 15416 scale as the minimum for retail.

Regulatory information

Packaging must carry the information required by law in each market, such as product name, ingredients, allergens, net quantity, dates, storage instructions, manufacturer details and country of origin. Sri Lanka’s Food (Labelling and Advertising) Regulations 2022 replaced the 2005 regulations, and UAE labels must be in Arabic, or Arabic and English. Our article on packaging quality control explains labelling checks in detail.

Finishing options for packaging

Finishing adds both protection and shelf appeal:

• Varnishes protect printed surfaces and can add gloss or matt effects.
• Lamination adds strength and a premium feel.
• Spot UV highlights logos and images.
• Foil stamping adds metallic accents.
• Embossing and debossing create texture.
• Windows show the product inside.

Every finish must be compatible with the board, gluing and the product’s recyclability goals. Our article on print finishing explains each option in more detail.

Colour consistency across materials

Brands often use several packaging materials in one range: board cartons, paper labels, film labels, pouches and tins. The same brand colour can look different on each, because materials absorb and reflect ink differently and may be printed by different processes.

To keep colours consistent:

• Define brand colours for each material in the brand guidelines.
• Use spot colours for critical brand colours where practical.
• Approve colour proofs on, or simulated for, each actual material.
• Compare printed samples side by side under standard lighting.
• Keep approved samples as references for future reprints.

Perfect matching across every material is not always possible, but careful management keeps differences small and the range looking like one family.

Batch codes, dates and variable information

Most packaging needs information that changes with each batch, such as production dates, expiry dates and batch codes. This is usually added during packing using inkjet, laser or thermal coding equipment.

Packaging design must:

• Leave a clear, uncoated or suitable area for coding.
• Place it where it is easy to read and not hidden by folds or closures.
• Allow for the coding equipment’s size and position on the packing line.

Testing coding on printed samples prevents smudged or unreadable dates.

Working with packing lines

Cartons and labels must run smoothly on the customer’s packing equipment. Problems such as cartons that do not open cleanly, glue that fails, labels that wrinkle or misalign, or packs that jam can stop production.

Before large runs:

• Share machine specifications with the packaging printer.
• Test samples on the actual equipment.
• Check carton board stiffness, crease quality and glue strength.
• Check label roll direction, core size and roll diameter for automatic applicators.

Shipping cases and secondary packaging

Products travel in shipping cases, usually corrugated boxes, that protect them and carry information for warehouses and retailers. Good shipping cases:

• Are strong enough for stacking during storage and transport.
• Fit products snugly to prevent movement.
• Carry clear shipping marks, product codes, quantities and handling symbols.
• Fit standard pallets efficiently.
• Can be shelf-ready, opening to display products directly on store shelves where retailers require it.

Protecting against counterfeits

Successful brands, especially in cosmetics, medicines and premium foods, can be targets for counterfeiters. Packaging features that help protect products include tamper-evident seals, unique serial or QR codes that customers can verify, special inks and holographic foils. Choosing features depends on the risk level and budget.

Proofs and samples

Before production, brand owners should approve:

• A PDF proof of the artwork on the dieline, checking text, barcodes and regulatory information.
• A colour-accurate proof for brand colours and product images, prepared for the chosen material.
• A physical sample or mock-up, made up into a carton or applied to a container.

For new cartons, a structural sample, often a plain, cut and creased prototype, checks fit before printing. Approvals should be recorded in writing for every element.

Flexible packaging and pouches

Many products, such as spices, snacks, coffee and powders, use flexible pouches and bags rather than cartons. Flexible packaging is usually printed on film by flexographic or gravure printing, then laminated with other layers to create barriers against moisture, oxygen and light, and finally converted into pouches with features such as zips, tear notches and hang holes.

Brand owners should consider:

• The barrier the product needs for its shelf life.
• Whether a mono-material structure can be used to improve recyclability.
• Minimum order quantities, which are often higher for printed films.
• How the pouch will look on shelf, standing or hanging.
• Space for batch coding after filling.

Our packaging team designs artwork for flexible packaging and works with specialist converters for printing and pouch making.

Designing for the shelf and for e-commerce

Packaging must perform in two very different environments. On the retail shelf, it needs strong brand blocking, clear product names and benefits visible from a distance. Online, it appears as a small image, so the brand and product must be recognisable at thumbnail size. When designing printed packaging, we review both views to make sure the design works wherever customers find the product.

Quantities and costs

Packaging print costs include one-off items, such as plates and cutting dies, and running costs, such as board, ink and machine time. Larger quantities usually reduce the unit cost. However, ordering too many cartons or labels risks waste if designs, regulations or recipes change.

Ways to manage cost include:

• Standardising carton sizes across a range where possible.
• Printing several designs together on one sheet.
• Using digital printing for small runs and new products.
• Planning reorders before stock runs out to avoid rush charges.

Quality checks during packaging production

Packaging production includes checks at each stage:

• Board and material inspection on arrival, checking grade, thickness and surface.
• Colour checks on the first printed sheets against the approved proof.
• Regular checks during the run for colour, registration and defects.
• Inspection of die-cutting accuracy, crease quality and stripping.
• Glue strength and alignment checks on folded and glued cartons.
• Barcode verification on samples from the run.
• Counting and packing checks before delivery.

Recording these checks creates a quality history that helps resolve any issue quickly and supports consistent reprints.

Storing packaging correctly

Printed packaging should be stored in clean, dry conditions, away from direct sunlight and extreme heat. Humidity can cause board to curl or lose strength, and labels can be affected by heat. Cartons should be stored flat in their original packing until needed, and stock should be used in the order it arrived.

Lead times

Packaging lead times include artwork, proofing, cutting die production, board supply, printing, finishing, die-cutting, gluing and delivery. New cartons with special finishes take longer than reprints of existing designs. Planning ahead avoids delays that can hold up product launches.

Because most board and label materials used in Sri Lanka are imported, availability can also affect timing. Sharing forecasts with the packaging printer allows materials to be ordered in advance, protecting launch dates and regular reorders.

An illustrative example

Here is an illustrative example. It does not describe a specific client.

A tea brand is launching a premium range of six blends in folding cartons, with matching labels for tins.

• Board. Folding boxboard is chosen for its bright surface and stiffness.
• Structure. A structural sample confirms that each carton fits 50 tea bags snugly.
• Printing. All six designs are printed together on one sheet by offset, with a brand spot colour.
• Finishing. Soft-touch lamination and gold foil create a premium look, while glue areas are kept clear.
• Labels. Film labels for the tins resist humidity in kitchen storage.
• Barcodes and labels. Each blend’s barcode is verified, and all regulatory text is checked for Sri Lanka and the UAE.
• Delivery. Cartons are die-cut, glued and delivered flat, ready for packing.

Common mistakes

• Designing artwork without the final dieline.
• Placing text or barcodes across folds.
• Choosing board too thin for the product’s weight.
• Varnish or foil on glue areas.
• Labels with adhesive unsuited to the container or conditions.
• Skipping physical samples.
• Ordering large quantities before regulatory text is final.
• Forgetting space for batch codes and expiry dates.
• Approving colour on a screen instead of on a printed proof of the actual material.
• Not testing new cartons or labels on the packing line before full production.

A packaging print checklist

1. Is the artwork placed on the final, approved dieline?
2. Is the board or label material right for the product and conditions?
3. Are inks and coatings suitable for food contact, where relevant?
4. Are text and barcodes clear of folds, seams and glue areas?
5. Have barcodes been verified?
6. Is all regulatory information correct for each market?
7. Is there space for batch codes and dates?
8. Has a physical sample been approved and tested on the packing line?
9. Are shipping cases specified and marked correctly?
10. Are quantities realistic, with reorders planned?

Frequently asked questions

What is a dieline?

A dieline is the flat technical drawing of a carton or label, showing cut lines, folds, glue areas and bleed. Artwork must be designed on the correct dieline.

Can you print small quantities of cartons?

Yes. Digital printing and short-run methods make small quantities practical for test markets and new products.

Do you supply both cartons and labels?

Dsigngo Group designs and prints packaging, labels and product boxes as part of its packaging design and print services.

Who makes the cutting die for our carton?

Cutting dies are made by specialist die makers from the approved dieline. The cost is usually charged once and the die can be reused for reprints, so it is worth agreeing who owns it and where it is stored.

How do we make our packaging more sustainable?

Options include recyclable boards, fewer layers, simpler finishes and right-sized cartons. Our blog article on sustainable manufacturing explains practical steps.

Conclusion

Printing labels and folding cartons combines design, materials science and precision manufacturing.
