FAIR Fine Art Checklist

Framed Photograph Glazing Contact, Spacer, and Mat Burn Checklist

Direct answer

If a framed photograph may be touching glass or acrylic, compressed by the frame package, missing spacer depth, or showing mat burn, gather external photos before opening anything. Contact, pressure, acidity, and light exposure affect both condition and safe handling.

  • Match the appraiser to the item category.
  • Confirm the report purpose before pricing.
  • Compare fee disclosure before outreach.

When checklist work prevents rework

Checklist pages are meant to improve the intake file. Better photos and notes help the appraiser decide scope, risk, and whether a formal report is justified.

Check contact before opening

A photograph pressed against glazing may show sticking, gloss change, cockling, flattened texture, or repeated pressure in the same area.

  • Take a straight-on front photo, then side-angle photos from all four sides.
  • Look for reflections that seem to sit directly on the image surface, not above it.
  • Flag slick patches, rainbow contact, cockling, pinched margins, or pressure lines near the mat window.
  • If adhesion looks possible, stop. Do not tap, flex, or try to separate the package.
Look for spacer or depth clues

Spacers and mat depth help keep the photograph away from glazing, but the absence of visible spacers does not prove the package is unsafe.

  • Photograph frame depth, mat thickness, visible air gap, spacer strips, and corner depth.
  • Check whether the gap is even or whether the print appears closer to the glazing in one area.
  • If the package looks tightly compressed or shifted, note that rather than forcing it open.
Separate mat burn from light damage

Mat burn and fading are different problems, though they often appear together in older frames.

  • Mat burn often appears as tan, yellow, or brown discoloration following the mat opening.
  • Light damage often appears as fading or tone shift between exposed image areas and protected margins.
  • Photograph any protected edge or covered strip that shows original paper tone.
  • Keep foxing, mold, silver mirroring, tide lines, mat burn, and abrasion as separate observations.
What to send to FAIR

A clear packet lets a photograph specialist decide whether the frame can stay closed, needs conservation review, or can proceed to appraisal.

  • Send full front, full back, side-angle, edge-depth, mat-window, and close-up condition photos.
  • Say whether the assignment is insurance, estate, donation, sale planning, purchase review, or general triage.
  • Mention seller claims about vintage printing, signatures, edition marks, prior conservation, or reframing.
  • Do not open the frame if the photograph appears stuck, moldy, water-damaged, brittle, flaking, or sharply cockled.
Common questions
  • How can I tell if a photograph is touching the glass? Side-angle photos are the safest first check. Look for bowing, gloss change, contact patterns, or reflections that appear fixed to the image surface.
  • Do spacers guarantee safety? No. Spacers help, but a photograph can still be under pressure from a tight package, warped backing, shallow mat depth, or past sticking.
  • What is mat burn? Mat burn is discoloration, often tan or brown, caused by acidic framing materials or prolonged contact near the mat opening.
  • Should I open the frame if the print looks stuck? No. Stop after external photos and ask a specialist or conservator for guidance.
