What is a decal?

According to the New Oxford Dictionary, a decal is "a design prepared on special paper for transfer onto another surface".

In the adhesive industry, a decal is defined by where it goes and how it performs, not by the design alone. Decals are made for a specific surface or environment, such as windows, walls, vehicles, doors, floors or signage. Placement, precision and durability matter, because a decal has to perform in real outdoor or commercial conditions. Decals can work as both decoration and functional graphics.

Printed decals

Printed decals are full-colour graphics that you apply in one piece, much like a large sticker: peel, position, apply. Typical examples:

• Single large shapes

• Graphics for windows, vehicles, doors, walls, floors or signage

• Large printed designs applied like an oversized sticker

Transfer decals

A decal is applied with transfer film when the design can't be lifted and applied as one piece, for example:

• Several cut pieces that must stay aligned

• Detailed lettering

• Spaced or separate shapes

• Delicate or thin design elements

The transfer film lifts all pieces and keeps them aligned while you apply them, and you remove it afterwards. Transfer is an application method, not a separate product type.

In short

• Stickers: peel and apply anywhere

• Decals: place, align and apply on a specific surface, often with a tool such as a squeegee

Most decals go on like large stickers. Only multi-piece designs need transfer film.

• Shopfront windows and commercial signage

• Vehicle branding, fleet graphics and business logos

• Wall decoration, murals and interior branding

• Floor graphics, directional and informational signs

• Equipment labelling and industrial use

• Exhibitions and trade show displays

Decals are used indoors and outdoors wherever placement, environment and durability matter. See Wall Stickers, Floor Stickers and Window stickers.

Printed decals have the same basic layers as stickers, but with materials, finishes and adhesives built for larger surfaces, outdoor exposure and long-term use.

1. Finish (top layer)

The finish protects the print and affects durability and texture.

• Glossy or matte laminate, both with UV protection

• 0.3 mm laminate for extra protection

• Anti-slip (sandy) laminate for floor decals

• Uncoated, for example wall decals for indoor use

2. Design (colour layer)

The printed artwork, in CMYK. White ink is used on transparent, metallic and speciality materials.

3. Material (base film)

The base film decides durability, flexibility and resistance to the environment. Our decals are printed on PVC (vinyl), which is more rigid and durable outdoors than the PET used for many stickers. PVC comes as calendered vinyl for standard use and cast vinyl for premium long-term use. Wall decals use a flexible polyester fabric.

The right material depends on:

• Indoor or outdoor use

• Surface type: smooth, textured or curved

• How long the decal should last

• How flexible it needs to be

4. Adhesive

The pressure-sensitive adhesive is chosen for the surface and conditions.

• Permanent: the standard for decals

• Hi-tack: for rough, textured or difficult surfaces

• Low-tack (removable): for temporary walls, events and short-term installations

The adhesive often decides how well a decal performs outdoors or on unusual surfaces. Read more in How do the adhesives differ?

5. Backing liner

A paper or film layer that covers the adhesive until you apply the decal. It keeps the decal flat and stable during transport and installation.

Decals can be made in two ways, depending on the design. Both are decals, but they behave differently and suit different graphics.

Printed decals

Full-colour artwork printed as one piece on vinyl. They only need transfer film if the design has several separate cut shapes.

Strengths

• Any colour, gradient, photo or detailed artwork

• Textures, shadows, patterns and multi-colour graphics

• Work well on smooth surfaces such as windows, doors, walls and vehicles

• High outdoor durability when laminated

Limitations

• The whole printed shape is one solid piece

• Elements can't be separated without cutting them apart

• Very large panels can be more complex to install

Use printed decals for

• Full-colour graphics, illustrations, photos and multi-colour logos

• Interior decoration such as wall decals and murals

• Floor decals with anti-slip laminate

Cut vinyl decals (Vinyl Transfer)

Made from solid-colour vinyl, with no printed ink: the colour is the vinyl itself. Each piece is cut separately and the excess vinyl is removed, so cut vinyl decals always need transfer film. Our version is Vinyl Transfer.

Strengths

• Very sharp edges

• Very durable outdoors without laminate, especially cast vinyl

• Great for lettering, logos, symbols and simple shapes

• No background: only the vinyl shapes remain

• Available in many vinyl colours

Limitations

• Each shape is separate and needs transfer film

• Not suitable for gradients, photos or complex artwork

• Multi-colour designs need several layers

Use cut vinyl decals for

• Shopfront lettering and opening hours on windows and doors

• Vehicle logos and fleet branding

• Signage icons, simple branding and single-colour symbols

• Long-term outdoor use

Read more in What are vinyl transfers?

• Printed decals: full colour (CMYK), handle photos, gradients and detailed illustrations. One solid piece, highly durable when laminated. Transfer film only for multi-piece designs. Best for large graphics, murals and branding

• Cut vinyl decals: solid-colour vinyl, one colour per layer, no background. Very durable, especially cast vinyl. Always applied with transfer film. Best for signage, logos and clean text
