Picture the size

How big is A5, really?

A4 is the familiar office sheet. A5 is half that size, A6 is half again, and A3 is twice the area of A4.

01 / The surface

Silk, gloss or uncoated?

The finish changes how light catches the paper and how the print feels in your hand.

Bond / uncoated

No glossy coating. A natural, matt surface that is usually the easiest choice for writing on.

Think: familiar 80 GSM office paper. Heavier uncoated stocks feel more substantial.
Choose for: forms, letterheads, notes and writable handouts.

Silk

Smooth with a subtle satin sheen. A versatile balance between a natural matt look and a glossy shine.

Think: polished promotional print without a highly reflective surface.
Choose for: business flyers, service lists, brochures and cards.

Gloss

A shiny coated surface that catches the light. A good match for photography and colourful designs.

Think: vivid, image-led promotions.
Choose for: event flyers, product promotions and photo-rich leaflets. Less suited to handwriting.

Pulp

An uncoated option with a natural character. Consider it for understated cards, tags and invitations. Pulp does not automatically mean recycled.

Recycled

Describes the fibre source, not one fixed texture or thickness. Choose a product explicitly labelled recycled and check its stated finish.

Kraft

A brown stock for a warm, rustic look. Its colour becomes part of your design, so colours will look different from printing on white paper.

Gloss paper is not gloss lamination. Paper coating is part of the stock. Lamination is a separate film added after printing. Only the options shown on your product are available.

02 / The substance

What does GSM actually mean?

GSM means grams per square metre: the weight of a sheet measuring one square metre. Within the same paper family, a higher GSM usually feels more substantial. It is not an exact measure of thickness.

80–100 GSM

Everyday & flexible

80 GSM bond is the familiar office-paper reference. A practical starting point for forms, notes and everyday correspondence.

120–130 GSM

Lightweight promotion

Consider 130 GSM silk or gloss for leaflet drops, event handouts and larger campaigns where you want to keep each piece light.

150–170 GSM

A substantial handout

170 GSM is a useful step up for a salon price list, a service leaflet or a flyer you hand to someone in person.

200–250 GSM

More presence

Try 250 GSM for a premium promotional handout, an event programme cover or a short promotional menu with a firmer feel.

300–350 GSM

Card-like & sturdy

A starting point for postcards, invitations, heavier covers and substantial flyers. Choose the right product for folds and finishing.

400 GSM

A confident card

A sturdy choice for business cards and heavyweight promotional pieces that need to make an impression in the hand.

Choosing between 130, 170 and 250? Pick 130 for a lightweight campaign, 170 for a more substantial everyday handout, or 250 when the piece should feel worth keeping. These are starting points, not rules. Size, stock and finish all affect the feel.

What if the stock says “mic” instead of GSM?

Microns measure thickness. For example, 380 mic means 0.38mm thick; it does not mean 380 GSM. Papers with the same GSM can have different thicknesses because their fibres, density and coatings differ.

Is heavier paper always better?

No. Light stock is easier to distribute in volume and keeps a booklet manageable. Heavy stock adds substance to a card or cover. For folded print, select a folded product so the paper and finishing suit the job; do not assume a thick flat flyer will fold neatly at home.

03 / The finishing touch

Lamination, without the confusion.

A thin film is bonded to the printed surface, adding a different look and feel and helping protect it during handling. It can be applied to one or both sides where the product offers it.

Matt

Low sheen and a smooth feel. Consider it for understated business cards and restrained designs.

Gloss

A reflective shine. Consider it when bold colour and photography lead the design.

Velvet / soft-touch

A soft, tactile, low-sheen finish. Consider it for premium cards and invitations that people will hold.

Illustrative matt, gloss and velvet lamination comparison

Print lamination

The film is trimmed flush with the paper. No clear plastic border. This is what the lamination choices on our print products mean.

Pouch encapsulation

The familiar office-laminator result: plastic surrounds the sheet with a sealed border beyond its edges. A different process, not what those product options provide.

Diagrams are illustrative. Lamination does not make paper waterproof: moisture can reach the trimmed edges. For writing or stamping, choose a suitable uncoated, unlaminated surface. Ask us first if your print needs frequent wiping or outdoor use.

Beyond paper

The right board for your big idea.

A wedding welcome, a shop display or a sign that stays outside. Choose the material for where it will go and how long you need it.

Illustrative cut edge: hollow channels

Correx

Lightweight corrugated polypropylene with a fluted core. A practical, economical choice for temporary signs, with weather-resistant plastic rather than paper.

Great for: event directions, property boards, construction notices and short-term promotions.

Shop Correx signs →

Illustrative cut edge: continuous foamed core

Foamed PVC / Foamex

A smooth, lightweight rigid plastic board that gives artwork a clean finish. It has a foamed PVC core, not the hollow flutes of Correx or the paper faces of foamboard.

Great for: wedding welcome signs, seating plans, exhibition panels, menus and retail displays.

Shop Foamex boards →

Illustrative cut edge: metal skins, polymer core

Aluminium composite / Dibond

Thin aluminium skins around a polymer core create a stiff, durable board with a smooth surface. A strong choice for longer-term signage indoors or outdoors.

Great for: business signs, directional panels, property signage and lasting outdoor displays.

Thickness is measured in millimetres, not GSM. The same thickness can behave differently across materials. Larger boards need suitable support, and outdoor signs need secure fixing for their location. The diagrams show construction, not actual scale.
