We are about ten kilometres from the sea. Salt air, monsoon humidity and afternoon sun are three problems that a printer inland does not have to think about, and they cause most of the frames that come back to us.
What humidity actually does
MDF swells. It is compressed wood fibre and it absorbs moisture out of the air. It absorbs unevenly, faster at the exposed back than the laminated front, and that differential is what bows a frame. Once bowed it does not come back.
Glass traps condensation. A glass-fronted frame on a wall that shares a surface with a bathroom or an outside face will collect moisture between the glass and the print. That is what causes the fogging and the tide-mark stains people bring in.
Mount board yellows. Acidic mount board reacts with atmospheric moisture and browns from the edges inward. On a ten-year-old frame it is usually the first visible failure.
Acrylic does none of this. It is non-porous, there is no glass and no mount board, and the ink is UV-cured into the surface. It is the reason we push acrylic here more than a printer in Hyderabad would.
Five things that genuinely help
- Choose the wall before the frame. A wall shared with a bathroom, kitchen or outside face stays damp. Move the frame two metres and you solve more than any material choice will.
- Leave an air gap. Frames pressed flat against a wall trap moisture behind them. The standoff bolts on acrylic frames create a gap by design; for MDF, two small felt pads at the bottom corners do the same job.
- Keep it out of direct afternoon sun. Every print fades eventually. UV-cured ink on acrylic lasts far longer than photo paper, but nothing survives years of direct western sun.
- Do not use glass cleaner on acrylic. Ammonia and spirit haze the surface permanently and it cannot be polished out. A dry or slightly damp soft cloth is all it needs.
- Get a second copy of anything irreplaceable. The cheapest insurance we sell is a ₹10 photographic print of a photo you cannot replace, kept in an envelope in a cupboard.
What to choose for where
| Where | Recommended | Avoid |
|---|---|---|
| Hall, interior wall | Anything, MDF is fine | , |
| Wall shared with bathroom | Acrylic | MDF, canvas, glass |
| Facing afternoon sun | Acrylic, matte | Gloss photo paper |
| Open verandah | Acrylic only | Everything else |
| Puja room | Acrylic, smoke wipes off | Canvas, textured mount |
| Shop, near open shutter | Acrylic, 5mm | MDF, canvas |
Storing prints you are not framing
Flat, not rolled, in an envelope, inside a cupboard rather than a trunk. Do not stack loose prints face to face in humidity, the emulsion can stick, and separating them takes the image with it. A sheet of plain paper between each is enough to prevent it.
Old photographs
If you have prints from the 1970s, 80s or 90s in a cupboard, scan them now rather than later. Colour dyes from that era shift steadily toward magenta and the process does not stop. We scan and restore from ₹500 per photograph, and a photograph scanned today can be reprinted forever.
Bring the original print, not a phone photograph of it. A phone picture keeps every fault and adds glare and lens distortion on top.
