Short answer: For most industrial brochures, a heavier cover stock (commonly in the 250 to 350 GSM range) paired with lighter inner pages (commonly 130 to 170 GSM) gives a document that feels solid without becoming bulky or expensive to post. Matt or silk coated paper suits technical content because it reduces glare on tables and drawings, while gloss works best for photo-led pages. Finishes such as matt lamination, soft-touch and spot UV should protect the brochure and highlight a few key elements, not decorate every page.
Paper and finish decisions are often left until the files are ready for print, but they shape how a buyer experiences your brochure the moment they pick it up. This guide explains the main choices in plain language so manufacturers, engineering firms and industrial suppliers can brief their designer and printer with confidence. It works alongside our industrial brochure design guide, which covers structure and content.
What GSM means and why it matters
GSM stands for grams per square metre. It measures the weight of the paper, which roughly tracks how thick and stiff it feels in the hand. Higher GSM means a heavier, sturdier sheet. Weight alone does not tell the whole story, because two papers of the same GSM can differ in thickness (often called caliper or bulk) depending on how they are made.
For an industrial brochure, GSM affects three practical things:
- Perception: a flimsy cover can undercut the message that your products are robust and well engineered.
- Durability: brochures handed out at exhibitions, carried to site meetings or left on a purchase manager’s desk need to survive handling.
- Weight and cost: heavier stock raises paper, printing and courier costs, which matters when you are posting catalogues to distributors or overseas buyers.
Typical paper weights for industrial brochures
Every printer stocks slightly different papers, so always ask for samples. As a general starting point, these are the ranges designers and printers commonly work with:
- Cover of a multi-page brochure or catalogue: around 250 to 350 GSM. This gives a firm cover that protects the inner pages.
- Inner pages: around 130 to 170 GSM. Heavy enough to avoid show-through of images and dark backgrounds, light enough to keep thicker catalogues manageable.
- Single-sheet leaflets and product flyers: often around 170 to 250 GSM, depending on whether they are folded.
- Bi-fold and tri-fold brochures: mid-range weights fold more cleanly. Heavier stock usually needs creasing before folding to avoid cracking along the fold.
- Large technical catalogues: lighter inner pages help keep a thick perfect-bound or wire-bound catalogue from becoming heavy, which is useful for export shipments.
The right answer depends on page count, binding method and how the brochure will be used, so treat these as conversation starters with your printer rather than fixed rules.
Coated vs uncoated paper
Coated paper has a surface layer that keeps ink sitting on top of the sheet, giving sharper images and richer colour. It comes in three common surfaces:
- Gloss: high shine and strong colour. Good for product photography and image-led pages, but glare can make dense tables and small text harder to read under exhibition or factory lighting.
- Matt: no shine, very readable. A safe default for technical brochures with specification tables, drawings and certificates.
- Silk (also called satin): a middle ground with a soft sheen. It keeps images vivid while remaining comfortable to read, which is why it is popular for corporate brochures and company profiles.
Uncoated paper has a natural, slightly textured feel and is easy to write on. It suits letterheads, notepads and some premium or sustainability-focused pieces, but images look softer because ink absorbs into the fibres. For most industrial product brochures, coated stock is the more practical choice.
Lamination and special finishes explained
Finishes are applied after printing to protect the sheet or draw attention to specific elements. Use them with purpose.
Matt lamination
A thin film that gives a smooth, non-reflective surface and protects against scuffs, moisture and fingerprints. It is a sensible choice for covers that will be handled repeatedly at trade shows or on site.
Gloss lamination
Adds shine and makes colours pop. It suits image-heavy covers but shows fingerprints more easily.
Soft-touch (velvet) lamination
Gives a velvety, premium feel. It works well for corporate brochures and company profiles aimed at senior decision makers, though it can mark more easily than standard matt film.
Spot UV
A clear, glossy coating applied only to selected areas, such as a logo, product image or headline. On a matt laminated cover it creates a subtle contrast that catches the light. Keep it to one or two focal points so it stays effective.
Embossing, debossing and foil
Embossing raises an element, debossing presses it in, and foil stamping adds a metallic layer. These suit milestone brochures, anniversary books and premium corporate kits more than everyday product leaflets, and they need extra lead time.
Matching paper to how the brochure is used
- Exhibition handouts: choose durable but not overly heavy stock, since visitors carry many brochures. Matt laminated covers resist wear.
- Sales meeting leave-behinds: a slightly heavier cover and silk inner pages create a quality impression on the desk.
- Technical catalogues used on the shop floor: prioritise readability and durability. Matt inner pages and a laminated cover work well, and wire binding lets the catalogue lie flat.
- Export mailers and distributor kits: balance quality with shipping weight. Ask your printer for a dummy so you can weigh it before committing to a full run.
- Brochures that will also be shared as PDFs: design for both. Our article on digital vs printed catalogues explains how to plan one master file for both uses.
Practical checklist before you approve print
- Ask the printer for physical paper samples and, for larger runs, a blank dummy with the actual binding.
- Confirm the binding method (saddle stitch, perfect binding or wire-o), since it affects how many pages and which weights are feasible.
- Check that the design includes bleed and safe margins as the printer specifies.
- Make sure dark solid backgrounds and large images are printed on a stock heavy enough to avoid show-through.
- Request a hard proof for colour-critical items such as brand colours and product finishes.
- Agree on finishes in writing, including where spot UV or foil will be applied, with a separate mask file if required.
- Plan lead time: special finishes and lamination add extra production days.
Frequently asked questions
What GSM paper is best for an industrial brochure?
A common combination is a cover around 250 to 350 GSM with inner pages around 130 to 170 GSM. The best choice depends on page count, binding and how the brochure will be used, so confirm with physical samples from your printer.
Is matt or gloss better for a technical brochure?
Matt or silk is usually better for technical brochures because it reduces glare on tables, drawings and small text. Gloss suits pages led by product photography.
Should a brochure cover be laminated?
For brochures that will be handled often, such as exhibition handouts or catalogues used on site, lamination protects the cover from scuffs and moisture. Matt lamination is a practical, professional default.
What is spot UV used for on a brochure?
Spot UV adds a clear gloss coating to selected areas, such as a logo or product image, to create contrast and draw the eye. It works best when used sparingly on one or two focal points.
Can one design work for both print and PDF?
Yes. Many brands create a print-ready master file and export a lighter, screen-optimised PDF for email and WhatsApp sharing. Plan colour, links and file size for both from the start.
