Label printing is the process of printing text, images, barcodes and colors onto a label material that is later attached to a product, package or surface.
A label looks simple, but many choices sit behind it: the printing method, the material, the adhesive, the finish and the shape. Choose well and the label stays sharp, sticks where it should and looks right on the shelf. Choose badly and it peels, smudges or fades.
This guide explains what label printing is, the 5 main printing methods, the common materials and formats, and where each is used. It ends with an artwork checklist and a look at why labels are a strong product to sell online.

What Is Label Printing?
Most labels you see are pressure-sensitive labels. They are made of three layers:
- Face material: the printed layer, such as paper or plastic film.
- Adhesive: the sticky layer that bonds the label to a surface.
- Liner: the backing sheet that you peel the label from.
Label printing puts the design on the face material, then cuts the label to shape. The finished labels are supplied on a roll or on flat sheets. Some labels use other methods, such as glue-applied paper labels on bottles or shrink sleeves, but pressure-sensitive labels are the everyday standard.
Labels do more than decorate. They identify a product, carry a barcode, list ingredients or safety information, show a brand and sometimes prove that a package has not been opened.
5 Types of Label Printing Methods
The method you pick affects cost, speed, quality and how many labels you can make economically. These are the five you will meet most often.
1. Digital Printing
Digital label printing prints straight from a file, using inkjet or toner technology, with no printing plates. That makes it quick to set up and a good fit for short runs, many versions of one design and fast turnarounds.
Best for: small and medium runs, seasonal products, test batches and labels with many variations.
Watch out for: the cost per label may not drop as much on very large runs, so compare it with flexo at higher volumes.
2. Flexographic Printing
Flexo uses flexible plates and fast rotary presses. It is the long-standing workhorse of label printing and suits long runs of the same design, because the plates cost money up front but each label becomes cheap once the press is running.
Best for: large volumes, repeat orders of one design and consistent color across big runs.
Watch out for: plate and setup costs make short runs less attractive.
3. Thermal Transfer Printing
Thermal transfer uses heat to melt a ribbon onto the label surface. It produces durable, smudge-resistant text and barcodes. You often see it in warehouses, asset tags and product identification.
Best for: barcodes, serial numbers and labels that must last.
Watch out for: it is mostly used for one or two colors and data, not full-color artwork.
4. Direct Thermal Printing
Direct thermal needs no ink or ribbon. Heat darkens a special coated paper. It is the method behind many shipping labels and receipts.
Best for: short-life labels such as shipping labels.
Watch out for: the print can fade with heat, light and time, so it is a poor choice for labels that must last.
5. Screen Printing
Screen printing pushes ink through a mesh stencil, building up a thick, vivid layer. It is used for specialty labels and for marks that need strong opacity or durability.
Best for: specialty and industrial labels that need bold, durable color.
Watch out for: setup is slower and costlier than digital for small jobs.
Labels can also be finished with extras such as foil, embossing or varnish. For a deeper look at how presses and methods compare, Labels and Labeling covers label printing technology across the trade.
Label Materials, Adhesives and Finishes
The right material depends on where the label will live. Will it face water, cold, oil, sun or rough handling?
Common face materials:
- Paper: economical and easy to print. Good for dry goods, boxes and indoor use. Coated paper gives sharper color, while uncoated and kraft paper give a natural look.
- Polypropylene film: a flexible plastic that resists water and tears. Popular for beverages, cosmetics and bottles you squeeze.
- Polyethylene film: soft and flexible, suited to squeezable containers.
- Polyester film: strong, heat-resistant and durable, used for industrial and outdoor labels.
- Vinyl: tough and weather-resistant, a common choice for stickers and outdoor signs.
Adhesives:
- Permanent: bonds firmly and is meant to stay.
- Removable: peels off cleanly, useful for pricing and temporary labels.
- Freezer grade: made to stick at low temperatures.
Finishes: varnish adds shine or a matte look, lamination adds protection against scuffs and moisture, and foil or embossing adds a premium feel.
Label Formats and Shapes
Labels come in several formats, and the format changes how you apply them.
- Roll labels: wound on a core, ready for hand dispensers or automatic applicators. Best for production lines and high volumes.
- Sheet labels: flat sheets that can be printed on desktop printers or ordered ready-made. Handy for small batches.
- Die-cut labels: cut to a custom shape, such as circles, ovals or irregular outlines, to match the product.
- Wraparound labels: wrap around a container, covering a bottle or can from side to side.
- Shrink sleeves: a plastic sleeve that shrinks to the shape of a container for full coverage.
A custom shape can set your product apart, but it needs a cutting die, so check the setup cost for short runs.
Label Printing Applications by Industry
Label printing is used wherever a product needs to be identified or branded. Typical uses include:
- Food and beverage: product names, ingredients, nutrition panels and branding on jars, bottles and packs.
- Cosmetics and personal care: premium finishes and water-resistant materials for bottles and tubes.
- Health and pharmacy: clear, accurate information and tamper-evident seals.
- Industrial and chemical: durable labels for warnings, handling instructions and identification.
- Logistics and warehousing: shipping labels, barcodes and tracking tags.
- Retail: price labels, shelf labels and branded stickers.
- Promotional and events: stickers, badges and giveaways that carry a brand.
Food, drink, cosmetic, medicine and chemical labels often have legal requirements that differ by country, so check the rules for your product and market before you finalize a design.
How to Choose a Label Printing Method?
Use this table as a starting point for label printing decisions.
| Method | Best run length | Strengths | Limits |
|---|---|---|---|
| Digital | Short to medium | Fast setup, many versions | Cost per label may stay higher on big runs |
| Flexographic | Long | Low cost per label at volume | Plate and setup costs |
| Thermal transfer | Any | Durable barcodes and text | Mostly one or two colors |
| Direct thermal | Any | No ink or ribbon | Fades over time |
| Screen | Short to medium | Bold, durable color | Slower setup |
Ask three questions:
- How many labels do you need? Short runs favor digital. Long runs favor flexo.
- How long must the label last? Long life points to film materials and thermal transfer, not direct thermal.
- How much variety do you need? Many designs or versions favor digital printing.
How to Order Labels: Artwork and Proof Checklist?
Good label printing starts with good files. Before you send artwork, check these points:
- Size and shape: confirm the exact label dimensions and the die line for custom shapes.
- Bleed and safe area: extend the background past the cut line and keep text inside the safe area.
- Resolution and format: use high-resolution or vector artwork, and ask your printer which file type it needs.
- Color mode: ask whether the printer wants CMYK or specific spot colors, and expect slight color shifts between screen and print.
- Barcode quality: keep barcodes dark on a light background, with enough empty space around them, and test that they scan.
- Proof: always review a proof, and order a sample if the label must meet strict standards.
Why Label Printing Suits Online Ordering?
Labels are a repeat-order product. A brand that needs 5,000 jar labels this month will need them again, often with the same artwork and a small change. That makes label printing a strong fit for online ordering, because the sizes, materials and pricing can be set up once and reordered in minutes.
For a print shop, that means fewer emails and fewer quote requests. For the customer, it means placing an order at any hour and reusing approved artwork. It is also the kind of recurring work that a corporate storefront is built to handle, where a business client logs in to an approved catalog and orders at agreed prices.
