Print coating against humidity

[mminegis]

I have this rather specific (and daunting) task to:

maintain the print quality for around 6 months;
in a rain forest/99% humiditiy environment/costa rica;
on a photo rag paper (hahnemuhle).

What is the most effective coating spray available on market for the above purpose? Has anyone tried Hahnemuhle protective spray?

Also, if I print on canvas, would the success rate increase??? (I have yet to try canvas so I have no idea). I print with an epson 2400.

Thank you for your suggestions!!!

I just realised that the coating itself can be counterproductive to near 100% level humidity. I was reading about the difference between microporous coating and polymer. Not that I understand much about them!

If anyone knows any suggested maker/product for protection against humidity, please help!

Thank you...

You do not give any information how the print will be used. Stapled to a tree in the jungle ? Framed behind glass in an air conditioned home or on the fridge in a treefeller's cabin ?

I need to keep them with me for a while, until I send them off to NYC.
How am I going to keep them? - in an original box that paper sheets come in? Unless there's a better way.... It's 13' x 19'...

Use Clear Star Protective Spray.  They are known as the liquid laminate.  If you seal the edges and back and front it will last and be waterproof.

Vacuum packaging. In air tight bags. Or in a  10" wide tube container that can be opened and perfectly sealed at one end + a vacuum pump system like used for food containers, wine, etc. Heavy PVC sewer tube with a cap at one side and threaded cap + sealing ring at the other side. You could still add silica gel for drying what remains of the air + a fungicide. If you also have to print in that condition (and your description suggests that) you need to dry the paper before it is printed as well. Spraying or laminating a print that is already at 99% humidity will only encapsulate the moist and that isn't a good thing to start with in a climate like that. If kept dry enough and the container is crash proof I think there's enough protection and no spray is needed. If that printer has to be used there too be aware of fungi that is feeding off the glycol etc in the ink.

Thank you two for the information. I'm sorry I wasn't articulate enough, but I'll make prints in a normal (dry/summer) weather condition - > carry them into a tropical weather. So laminating can be an option. I haven't thought of vacum packaging option - interesting. It's just a matter of finding the right tool, I suppose. Where would you buy "Heavy PVC sewer tube" you mentioned?

I will read the pdf on print permanence.

Fungus thing is a bit scary... will have my laptop serviced/cleaned before I go!

Lowes, Home Depot or any number of hardware stores.  Its pretty inexpensive.
