Photography Face-Mount, Board-Mount, and Dry-Mount Checklist

Support attachment changes what a specialist can learn from the object and what evidence may already be hidden or permanently altered.

• A loose photographic print, a top-hinged print, a board-mounted print, a face-mounted print under acrylic, and a dry-mounted print do not present the same appraisal questions or handling risks.
• Mounting can cover margins, verso inscriptions, lab stamps, paper-brand marks, edition notes, and edge construction that help date and interpret the print.
• Some mounts are reversible with conservation treatment, while others are effectively permanent for buyer decision-making purposes and should be treated as such until a specialist advises otherwise.
• This checklist is for evidence gathering before appraisal. It is not a removal or conservation-treatment guide.

Use plain-language observations instead of forcing a technical conclusion too early.

• Face-mounted usually means the image surface appears bonded directly to acrylic or another clear face layer, often with the print backed by a rigid panel such as Dibond, aluminum composite, or another support.
• Board-mounted usually means the photographic sheet has been attached to a rigid or semi-rigid support board, mat board, foam board, card, or another backing that travels with the print as one unit.
• Dry-mounted usually means the print appears adhered overall to a backing support with heat-activated tissue or a similar adhesive layer rather than being held only by hinges, corners, or edge attachments.
• If you cannot tell which term fits, describe what you actually see: acrylic front, rigid back panel, paper fully adhered to board, only top hinges visible, loose corners, or unknown.

The specialist needs to know when the print no longer behaves like a loose sheet and when verso evidence may be inaccessible without treatment.

• The print and support move as a single rigid unit, with no visible separation between the paper and the backing board when viewed from the side.
• There is no visible hinge, corner pocket, spacer gap, or free paper edge anywhere the specialist would normally expect to see one.
• The image layer appears bonded to acrylic or another clear facing, especially when the front surface has a very uniform polished look and the paper cannot be seen moving independently beneath it.
• Margins, verso markings, and paper edges are fully buried under a mount package, laminate, or backing panel that does not open like a normal frame package.
• The seller or framer describes the work as mounted on aluminum, Dibond, Sintra, Gatorboard, foam board, Masonite, archival board, or dry-mounted tissue without showing loose-sheet evidence.
• Pressure bubbles, lifting corners, delamination lines, or adhesive shadows may signal mounting failure, but they also confirm that attachment is part of the object now and should be documented before anyone tries to separate layers.

Start with a complete evidence set that preserves the object exactly as found.

• Full front straight-on photo showing the entire object or framed package, including visible margins, glazing, border treatment, and how the image sits within the support.
• Full reverse photo showing the entire back panel, hanging hardware, labels, stickers, frame shop notes, edition labels, and any exposed support material.
• Side-angle photos from all four sides so the specialist can judge thickness, layered construction, spacer gaps, acrylic depth, and whether the paper edge is visible or buried.
• Corner close-ups front and back showing how the face layer, print, support board, and frame package meet at the edges.
• Close-ups of any visible free edge, lifted area, bubble, delamination line, tape line, hinge, corner pocket, or exposed support where attachment clues are easiest to read.
• Photos of labels, invoices, certificates, edition paperwork, or lab and framer notes that mention face-mounting, mounting substrate, laminate, dry-mount tissue, or board type.

Once the baseline photo set is complete, gather a few targeted angles that answer the support-attachment question more directly.

• Take one raking-light photo across the front so bubbles, silvering, adhesive texture, pressure lines, or an acrylic-face layer become easier to see.
• Photograph the thinnest visible edge so the specialist can tell whether the paper is sitting on top of a board, sandwiched under acrylic, or recessed away from a face layer.
• If the back panel is exposed, photograph the support material close enough to show whether it looks like foam board, mat board, wood-based board, aluminum composite, or another rigid substrate.
• If the object is framed, photograph the frame depth and the gap, if any, between glazing and print. A truly face-mounted work may not have the same spacer relationship as a traditionally framed loose print.
• If a corner is already lifting on its own, photograph it without pulling further. That natural separation can show whether the attachment is edge-only, full-sheet, or face-mounted.

Mounting questions often become worse when a buyer tries to prove reversibility by force.

• Do not peel corners, test adhesion with a fingernail, slide tools under the sheet, or try to separate acrylic from the image surface.
• Do not remove backing panels that appear glued, taped shut under tension, or structurally integrated into the mount unless a specialist specifically tells you it is safe.
• Do not flex a mounted print to see whether the paper releases. Rigid movement is itself evidence and the test can crack emulsions or shear the sheet from its support.
• If the work appears valuable, unusually large, glossy under acrylic, or already shows bubbling, blocking, or delamination, stop after documentation and ask the FAIR photograph specialist how to proceed.

A short mounting summary makes the photo packet more useful and helps route the object to the right specialist or conservator.

• State whether the print is loose, hinged, board-mounted, face-mounted, dry-mounted, framed with unknown attachment, or uncertain.
• List the visible support materials in plain language, such as acrylic face, aluminum composite backer, foam board, mat board, wood panel, or unknown rigid board.
• Mention whether any verso information is hidden by the mount and whether any labels or paperwork claim vintage print status, edition details, or printer information.
• Report warning signs such as bubbles, edge lift, adhesive stains, ripples, pressure marks, blocked surface, or evidence that the print cannot move independently from the support.
• If the main concern is whether important verso evidence has been lost or concealed, pair this checklist with the framed backing-board and hinge guide and the print-process checklist when contacting FAIR.

• Is a face-mounted print the same as a dry-mounted print? Not necessarily. Face-mounting usually describes a print bonded to a clear face layer such as acrylic, often with a rigid backer as part of the package. Dry-mounting usually refers to broad adhesion of the print to a backing support. A work can involve one or both types of attachment, which is why side and edge photos matter.
• Why does irreversible mounting matter to an appraiser? Because mounting can hide or eliminate evidence from the margins and verso, change condition and presentation, and affect how the exact object should be compared with loose or differently mounted examples.
• Should I remove a mounted photograph from its support before appraisal? No. Document the object as found and stop. Separation attempts can damage the print and erase evidence that a specialist needs to see first.
• What if I can only photograph the framed object and not the support directly? That is still useful. Send the full front, full back, side angles, corner details, and any paperwork. A FAIR photograph specialist can often tell whether more access is necessary or too risky.
• What page should I read next after this checklist? Use the framed photograph backing-board and hinge checklist for package-access questions, the print-process and paper-surface checklist for process clues, and the resin-coated vs fiber-paper edge checklist when paper construction is still visible.
