Sunboard – forex, foam PVC, call it what your supplier calls it – is the volume king of Indian signage, and the first media every flatbed owner prints daily. It is cheap, flat, dust-friendly and everywhere. This guide covers what to print on it, direct flatbed printing versus the old vinyl-paste method, and the rates that keep a signage shop busy all month. All figures are estimates (est.).
Sunboard Products and Rates (est.)
| Product | Board Grade | Sell Rate (est.) |
|---|---|---|
| Shop front / indoor boards | 3-5 mm | Rs 90-150 per sqft |
| Exhibition and event panels | 3-5 mm | Rs 100-180 per sqft |
| Photo mounting boards | 3-5 mm white | Rs 120-200 per sqft |
| Standee / human cutouts | 5 mm, router cut | Rs 150-300 per sqft |
| Danglers and POS displays | 2-3 mm | Rs 100-200 per sqft |
| Outdoor short-term boards | 5 mm + lamination | Rs 130-220 per sqft |
Direct Flatbed Print vs Vinyl Pasting: The Honest Comparison
Direct UV print on sunboard costs more ink-side – Rs 55-80 per sqft all-in (est.) against Rs 30-45 for a pasted eco solvent print (est.) – and for a commodity 50-board local job, pasting still wins on pure cost. Direct print wins where finish and speed matter: no bubbles, no peeling edges, no pasting labor, one-pass delivery and sharper small text. Premium retail, exhibitions and corporate work now specify direct print, and a flatbed shop quoting Rs 90-150 (est.) on those jobs keeps both margin and the customer.
Prep and Handling on the Bed
Three habits keep sunboard prints clean. Dust wipe every sheet – board vendors ship sheets straight off dusty godown floors. Lay sheets flat in storage; bowed 5 mm board is the top cause of head strikes in this segment. And run the vacuum bed on every job, because sunboard is light enough to shift under the carriage. These three save more heads than any maintenance schedule.
Which Grade to Stock
3 mm runs the volume – shop boards, danglers, exhibition panels – at Rs 25-40 per sqft cost (est.). 5 mm covers photo mounting, cutouts and premium boards at Rs 40-60 per sqft (est.). White prints cleanest colors; grey and black boards need a white underbase and are priced like specialty work. Reject wavy lots at the godown itself – no printer fixes a banana board.
Sunboard economics at real scale appear in the Rs 28 lakh signage plant case study (Kolkata) and the Rs 42 lakh UV signage unit case study (Chennai) – both run direct-print board work as the daily bread line.
Our Verdict
Sunboard will not make you rich on one job and it will never let the machine sit idle – that is exactly why it anchors every flatbed shop: volume pays fixed costs while acrylic and glass pay margins. Quote direct print for finish-led buyers, keep the pasting economics honest for commodity work, and handle sheets flat and wiped. Machine options live in our UV flatbed printer price guide and UV flatbed printer category.
FAQs – Sunboard UV Printing Guide: Rates and Uses 2026
What is the rate of sunboard printing per square foot?
Direct UV printing on sunboard sells at Rs 90-150 per sqft for shop boards, Rs 100-180 for exhibition panels and Rs 150-300 for router-cut standees (est.). All-in production cost sits near Rs 55-80 per sqft (est.).
Is direct UV printing better than vinyl pasting on sunboard?
For finish and speed, yes – no bubbles, no peeling, sharper text, one-pass delivery. For pure cost on commodity bulk boards, vinyl pasting stays cheaper at Rs 30-45 per sqft (est.). Premium retail and exhibition buyers now mostly specify direct print.
Which thickness of sunboard is used for printing?
3 mm handles shop boards, danglers and exhibitions; 5 mm covers photo mounting, cutouts and premium boards. Both print flat on a vacuum bed. Thicker 8-10 mm board exists for furniture-grade uses but is rarely printed.
How long does a printed sunboard last outdoors?
Direct UV print with lamination survives 1-2 years outdoors (est.) and 3-5 years indoors. The board itself fades and embrittles before the ink, which is why ACP is the correct upgrade for permanent outdoor boards.
Why do sunboard prints get pinholes and how to avoid them?
Pinholes come from dust and static on godown-stored sheets. One lint-free IPA wipe before printing removes both, takes twenty seconds per sheet, and saves the reprint. It is the cheapest quality step in the whole shop.
