How long can I keep my DS printouts?

[davidmfranks]

I usually gang up designs, say 4-up on A4 for coasters (old habits die hard). Ands end up with one or two that aren't sublimated.
Is there any limit of how long any unused extra prints are still, errr, "sublimatable"?

Obviously I'll keep them dry and out of sunlight. It seems so wasteful to leave acres of space on the paper, but has anyone tried subbing older prints?

I have no problems keeping prints. Humidity is the biggest problem in the British climate. The coating on the dye sub paper will absorb moisture which will effect the print. Let the print dry completely and then store in a ziplock bag or airtight box with a handful of absorbant sachets thrown in, away from heat and sunlight. (the same goes for opened boxes of blank paper).

That's really useful. Many thanks, pw66
