For low-cost, portable stands, rollable PVC wins on price and ease of transport. For durability across repeat events, rigid Foamex delivers a flatter, tougher finish. For a premium, seamless look, tension fabric or SEG systems beat both. Watch install complexity and van space before you commit, and these can be produced in-house by print suppliers.
TL;DR:
- Rollable PVC is ideal for frequent movers due to its light weight, portability, and affordability, but it requires careful handling to avoid creases.
- Rigid Foamex offers a flat, durable finish suitable for multiple shows, with heavier transport requirements but excellent longevity.
- Tension fabric or SEG systems provide seamless, premium-looking walls that photograph well, though they come at a higher initial cost and installation complexity.
- Panelled Foamex is easier to repair and swap out between events, making it better for short-term or repair-prone applications, while seamless fabric is more impactful for brand image.
- Material choice should align with the exhibitor’s schedule and reuse plans, with PVC best for short-term touring, Foamex for annual reuse, and fabric systems for high-end, flagship displays.

Shell scheme graphics options: material types compared
Every shell scheme graphics decision starts with substrate, and the three main options behave very differently once they leave the print bed. Rollable PVC, rigid Foamex, and tension fabric (often called TFS or SEG) each suit a distinct exhibitor profile, and picking wrong usually shows up as a creased panel or a cracked corner on the morning of the show.
Rollable PVC is the choice for exhibitors who move between venues often. It rolls into a tube for transport, resists light flexing without cracking, and one person can carry and fit it without help. The trade-off is handling care: fold it and you’ll see a permanent crease line under exhibition lighting, and it needs flat storage between uses.
Rigid Foamex, or foam PVC, is widely recommended at 3mm to 5mm thickness for a dead-flat, durable panel that survives repeated handling. It needs van space rather than a courier tube, and it’s heavier to carry, but it holds its shape event after event.
Tension fabric systems stretch a printed fabric skin across a frame, hiding joins and producing a genuinely seamless wall that photographs well. Fabric is lighter than Foamex, machine washable, and gives a premium feel that many exhibitors reserve for flagship stands.
- Rollable PVC: lightest, cheapest, best for solo installers and multi-venue tours
- Rigid Foamex: flattest finish, best durability, needs van transport
- Tension fabric/SEG: seamless, washable, premium perception, moderate weight
Pro Tip: Keep a spare rolled PVC panel flat in a plan chest between shows rather than re-rolling it tightly. Tight re-rolling is the single biggest cause of visible crease lines at the next event.
Seamless versus panelled shell scheme designs: which fits your stand?
Deciding between a continuous printed wall and a panelled layout with visible uprights comes down to budget, repairability, and how the stand will be photographed. Both are legitimate custom shell scheme designs, but they’re achieved in different ways.
- Magnetic over-the-pole kits and shell-clad clips attach individual Foamex or PVC panels to the shell’s aluminium uprights, often with a small offset of around 25mm to visually mask the pole rather than hide it entirely.
- Tension fabric systems (SEG) use a channel edge sewn into the fabric that slots into an aluminium frame, pulling the graphic taut across the whole bay so the uprights disappear behind the frame rather than the print.
- Weigh the trade-offs before you choose: panelled systems are cheaper to replace panel-by-panel if one gets damaged, while a seamless fabric wall costs more upfront but delivers stronger visual impact and cleaner photography for brand-led exhibits.
If your priority is repair cost and quick panel swaps between events, panelled wins. If the stand needs to look like a bespoke build on a shell scheme budget, seamless is the better route, and it’s the approach we’d generally recommend when brand impact matters more than unit cost.
What size are shell scheme panels and how do you measure them?
Shell scheme graphics sizes follow a fairly consistent industry pattern, but tolerances vary by organiser, so measuring on-site (or from a confirmed manual) beats guessing from memory. Bays are typically built in 1 metre wide sections, with wall panel heights commonly around 2.4 metres, because organisers usually supply Octanorm or Sodem-style aluminium framing built to those grid dimensions.
Measure across the uprights themselves, not just the visible infill gap, and factor in any offset needed for shell-clad clips before finalising your template.
- Confirm bay width and height against the organiser’s floor plan before artwork starts
- Add bleed (typically 5 to 10mm per edge) and keep a safe area clear of text near panel joins
- Check colour profile (CMYK, not RGB) and resolution (150 to 300 dpi at final size)
- Request a scaled PDF proof and, for multi-panel walls, a printed mock-up before the full run
Cross-checking the organiser’s own technical manual remains the safest habit, since grid tolerances genuinely differ between venues and event organisers.
How do you mount shell scheme graphics on-site?
Attachment method matters as much as material choice, because the wrong fixing either fails to hold or damages the shell scheme frame you’ll return at the end of the show.
- Velcro (hook-and-loop) tape is the most common fixing for PVC and Foamex panels. Apply strips in a grid pattern rather than just the edges, and replace tape that’s lost tack after three or four events.
- Magnetic strips work well on Foamex against steel-backed infill panels, but check the shell provider’s substrate first: some infill is aluminium composite, which won’t hold a magnet.
- Shell-clad clips and over-the-pole adapters clip directly onto the upright, letting panels sit slightly forward to disguise the pole line without needing adhesive at all.
- Build a small on-site toolkit before you travel: a 5 metre steel tape, a spirit level, a craft knife, spare high-tack adhesive tape, spare Velcro strips and a roll of magnetic tape covers most last-minute fixes.
Pro Tip: Pack one spare panel corner repair kit even for a single-day show. A lifted corner in hour one looks worse than a blank wall.
Do you need lightboxes or illuminated finishes on a shell scheme?
Lightboxes and illuminated finishes change how a stand reads from across the aisle, but they add technical planning that a flat printed panel doesn’t need. Backlit lightboxes and edge-lit frames both need a mains power run to the bay, confirmed with the organiser in advance, plus enough depth in the frame for ventilation so the LEDs don’t overheat behind the graphic.
Finish choice matters more than exhibitors often expect: matte laminates cut glare for visitors photographing the stand under exhibition lighting, while gloss suits bold colour blocks viewed from a distance.
- Aluminium SEG frames give a clean seamless edge with no visible fixings
- Routed elements and standoffs add depth but increase weight and install time
- Illuminated panels typically add 20 to 30 minutes to a standard install
- Anti-glare laminate is worth the small cost premium on any panel near overhead spotlights
Every accessory you add increases transport volume and setup time, so weigh visual impact against how much install time your slot actually allows.
What does a shell scheme graphics package actually cost?
Budgeting for exhibition display graphics works better as a lifecycle question than a single purchase price. Rollable PVC sits at the lowest cost tier, rigid Foamex in the middle, and seamless fabric or SEG systems at the top, though seamless systems can deliver a finish close to a bespoke build at a fraction of a full custom stand’s cost.
Transport shapes the real cost too, not just the print itself.
- PVC rolls into a tube and often travels by courier; Foamex needs flat van space or a hard case
- Fabric packs into a bag lighter than the equivalent Foamex panel, cutting freight weight
- Replace Velcro tape and wash fabric panels between shows rather than reprinting from scratch
- Hire makes sense for a single one-off event; buying suits anyone attending three or more shows a year
Good exhibition stand storage between events protects your investment more than any single material choice.
What file specs do exhibition graphics need before print?
Pre-press mistakes cause more reprints than material failure ever does, so treat the artwork stage as seriously as the material choice itself. Supply print-ready PDFs at full scale, CMYK colour, and 150 to 300 dpi resolution, since RGB files shift colour badly on large format printers.
Bleed and safe area aren’t optional extras. Build in bleed on every edge that meets a join or a pole, and keep critical text or logos clear of any offset needed for shell-clad clips.
- Use the supplier’s own template file, not a generic dieline pulled from another job
- Request a soft proof first, then a PDF sign-off, and ask for a physical proof on any run over a few panels
- Double-check panel numbering matches the install order, especially on multi-bay walls
- Confirm bleed and safe area against the confirmed bay measurements, not an assumed standard
Pro Tip: Always ask for a scaled PDF proof at 1:10, printed on paper. It catches sizing errors a screen preview never will.
How A3m approaches shell scheme graphics production
Shell scheme and exhibition graphics typically follow a workflow of confirmed template, proof sign-off, press checks, then delivery timed to the show date. In-house manufacturing can help ensure colour and finish checks occur under one roof rather than across multiple subcontractors, which helps maintain a tight turnaround when show dates are fixed.
Ask any supplier three things before you commit: whether they’ll dry-fit a sample panel against your actual bay dimensions, how the finished graphics pack for return and reuse, and whether PVC-free or recyclable substrates are available for your run. A3m offers sustainable print options across its large format range, alongside full modular exhibition build services for stands that need more than graphics panels alone.
Which shell scheme graphics suit different exhibition goals?
The right shell scheme graphics options often come down to what the stand is actually for, not just what looks best in isolation. A trade show veteran running the same regional circuit twelve times a year has a very different brief to a brand launching one flagship appearance at a national exhibition.
Consider a supplier running a five-city product tour across a single quarter. Rollable PVC panels make sense here: one person can pack, transport, and fit the graphics between venues without hiring extra install labour, and light creasing on a short-lived campaign matters less than it would on a permanent asset.
Compare that with a manufacturer attending the same three annual trade shows for years. Rigid Foamex earns its higher unit cost through repeated use, since the flat, durable panel survives storage and handling far better than a rolled substrate subjected to the same cycle a dozen times.
A luxury or hospitality brand debuting at a flagship show sits in a third category entirely. Here, seamless tension fabric or SEG framing tends to justify its cost premium: the continuous printed wall reads as a bespoke build rather than a rented shell, which matters when first impressions on the show floor directly shape how visitors judge the brand behind the stand.
None of these choices is universally “best.” Matching material to the actual exhibition calendar, not the biggest budget available, produces the stronger long-term outcome in each case.
Author perspective: quick decision rules for common briefs
Match the material to your calendar, not your budget ceiling. Touring several venues a year? Choose rollable PVC. Reusing the same stand annually? Choose Foamex. Launching a flagship brand moment? Choose seamless fabric. Where possible, ask about PVC-free alternatives; sustainability shouldn’t be an afterthought once the graphics are already specified.

FAQ
What is a shell scheme for exhibitions?
A shell scheme is a standard modular booth structure that organisers provide, typically aluminium framing with infill panels, which exhibitors then brand with their own graphics and accessories.
How much does a shell scheme booth with graphics cost?
Costs vary by material and bay size, since rollable PVC sits at the lowest tier, rigid Foamex in the middle, and seamless fabric systems highest. A3m’s exhibition and print pricing is available on request via A3m.
What are the main types of exhibition graphics?
The core types are rollable PVC, rigid Foamex (foam PVC), and tension fabric or SEG systems, each suited to different levels of portability, durability, and finish quality.
What are the different types of exhibition stands?
Beyond shell scheme, exhibitors can choose space-only builds or fully modular stands; shell scheme remains the most common entry point because organisers supply the base structure and exhibitors only need to brand it.
Should I choose seamless or panelled graphics for my stand?
Choose seamless tension fabric when brand impact and photography matter most; choose panelled Foamex or PVC when budget, repairability, and quick panel swaps matter more than a fully continuous wall.
