I bought and framed a 30 x 30 archival matte print a few months ago. I live in a humid area, and I notice on more humid days the paper noticeably warps. Other than the predictable warping, I am very happy with the quality of the paper and the print.
Which paper option comes close to the quality and texture of archival matte but is more resilient to humid conditions? Any other experiences or thoughts?
Any archival Museum paper is very sensitive to the humidity. So according to the level of the humidity in the environments the paper is going to react or curl. There's no solution except the maintaining the humid level .That's why in many museums, archival collectors use humid controlling meters and humidifiers to monitor their spaces. Only other way is to have prints on RC ( Resin coted = Plastic based) plastic based papers to have the photos. Or other wise canvas prints. RC papers are short longed and easily decaying to the environments Gas and UV light. That's is why they are cheaper than linen or fibre papers like Baryta ( a special barium sulphate coating) Paper.
Roy, to answer your question, I went into this clueless. I just appreciate art, wanted to beautify my apartment, and cluelessly bought the poster and frame hoping for the best. I did the framing myself (acrylic) and it shows.
I think Cyril's suggestions will help a lot as well. Question is which route to take: place my current print in a more appropriate frame, order the poster in RC (which I get the impression is less desirable), or both.
Well this is informative, Over the past weekend I created two giant artworks using archival luster photo paper a total of 40 sheets of 13" x 19" prints for the two projects.
What I did was glue the prints onto a 1/2" thick pvs sheet 4' x 8' and then I clear coated with crystal clear acrylic spray over the heavy 66lb archival photo paper, at first it all looked great but the next day is was warped. I thought it was the clear coat but in fact it wasn't, it appears to be the humidity, I live in Florida and these two days I did the work and they are outdoor works the humidity was really high as it had rained the night before.
Well at least now I know what I'm dealing with, I thought it might have also been a problem with the 3m spray adhesive I used used to glue the prints, but now it sounds like a humidity problem.
I'm wondering if I should do the next large works using real cotton canvas sheets to avoid the warping? If anyone knows I be happy to hear.
Thank you, Peggy. I half considered asking for at least a partial refund. Still not sure if it's justified, but as a layman in this world, I could have used more information when ordering. Humidity ought to be a major consideration.
And thanks for sharing that, Mario. Your investment was far more ambitious than mine, and unlike me it sounds like you know what you're doing. Sorry your project turned out like that. I wonder how much the warping might straighten out again in drier conditions?
Brian, good point you bring up about the prints getting better when the humidity is lower. That is actually what happened I brought them inside and laid the prints on the floor one on top of the other to weigh them down flat and left them over night. The following day I took them back outside in full sunlight and heat of the day and the warping improved greatly.
My experience after more than 50 years in custom framing, is that this is a constant issue with any work on paper. If you use thicker papers it will stay flat better than thinner papers 140lb water color vs a 300 lb. (very heavy paper) for instance. If the work is a poster I would simply dry mount it (usually in a heat press). It's a permanent process generally and a poster has little value. If it were a limited edition I would not mount it because it will devalue the print. For longevity, I never use spray mounts. They eventually bubble or otherwise break loose. Most spray mounts also have acid content and yellow with age.
Many assume that more is better when taping art into a mat. More tape simply exacerbates the issue because the paper can not move and will more likely buckle over time unless it is in a temperature/humidity controlled environment. Minimal, "T-hinges" at the top edge only is much better and not taped to the mat but to the backing. I avoid pressure sensitive tapes too. Even the, "acid free" pressure sensitive tapes can be problematic. They can let loose on a hot day. I'm in SC and yes almost everyone has AC however one day in the heat and things can happen.
Thanks Roy, I think you are right about the canvas, the marine grade plywood is priced like gold these days, lol! Actually the pvc board I like a lot it's not so heavy that I can't lift it by myself, I don't recall what I paid for those. I take these works outside but at the end of the day they come inside.
I have gotten used to the warping already and you really can't tell unless you are standing right in front of the pieces and even so they still look good to me. I will certainly look to correct this in future works. The canvas though I want to give a shot at.
