You have created a piece of Ebru that you love — a richly patterned print with colors and movement that seem to contain their own light. Now what? How do you display it, protect it, and ensure that it looks as beautiful in twenty years as it does today?
Ebru on paper is a durable medium when properly treated, but like all works on paper, it requires thoughtful handling, appropriate framing materials, and the right environmental conditions to last. This guide covers everything you need to know.
Understanding What You Are Preserving
Before discussing preservation, it helps to understand what Ebru paper actually is. A completed Ebru print consists of:
- A paper substrate — typically 80–120 gsm cotton or wood-pulp paper
- An alum coating on the printing surface (this is what makes the pigment adhere)
- Natural mineral or earth pigments bound to the paper surface
- A slight residue of the carrageenan or gum tragacanth sizing
The main threats to Ebru paper over time are: ultraviolet light (fades pigments and yellows paper), humidity fluctuations (cause expansion/contraction, buckling, foxing), physical contact (pigment can be abraded), and acid migration from non-archival framing materials.
Flattening Before Framing
Freshly completed Ebru prints often curl slightly as they dry — the alum-treated side contracts differently than the untreated side. Before framing, prints should be fully flattened.
The safest method:
- Allow the print to dry completely (24 hours minimum)
- Place it face-down on a clean, dry surface
- Cover the back with a slightly damp (not wet) cloth for 2–3 minutes to relax the paper fibers
- Place under a stack of heavy books for 12–24 hours
- The print should now be flat and ready to frame
Do not use heat (iron or heat press) directly on Ebru — this can damage the pigments and alter the colors permanently.
Choosing Archival Framing Materials
For any work on paper you wish to preserve for the long term, archival (acid-free) framing materials are essential:
Mat Board
Use only acid-free, lignin-free mat board (also called conservation-grade or museum-quality mat). Standard mat board is acidic — over time it migrates into the paper and causes yellowing and brittleness. The mat also keeps the glass away from the print surface, which is important.
Backing Board
Use archival foam board or acid-free mounting board. Never use regular cardboard or foam.
Glass
Standard glass transmits ultraviolet light, which fades pigments over time. For valuable pieces, use UV-filtering glass or acrylic (Plexiglas with UV protection). Museum glass offers the best UV protection with the least reflective distortion — it is expensive but worth it for significant pieces.
Adhesives and Mounting
Do not dry-mount Ebru paper with heat-activated mounting tissue — the process is irreversible and can damage the pigments. Use archival hinges (small strips of Japanese tissue paper with wheat starch paste) to attach the print to the backing, allowing it to move slightly with humidity changes. This is the standard museum method for works on paper.
Mounting Considerations
Ebru paper has a natural texture and slight irregularity — part of its beauty. Some framers prefer a "float mount" style, where the print is displayed with a small visible gap around all edges (as if floating on the backing), which showcases the print as a unique object rather than hiding its edges under a mat.
This approach requires careful execution — the hinges must be invisible from the front, and the print must be secured sufficiently to hold it flat without stressing the paper. A professional framer experienced with works on paper is the best choice for important pieces.
Display Conditions
- Light: avoid direct sunlight and strong halogen or incandescent spotlights pointing directly at the piece. Indirect natural light and LED lighting (low UV emission) are ideal
- Humidity: aim for relative humidity between 45–55%. Avoid displaying Ebru in bathrooms, kitchens, or near exterior walls subject to temperature fluctuation
- Temperature: room temperature (18–22°C / 65–72°F) is ideal. Avoid unheated storage spaces where temperature fluctuates widely
Storing Unframed Prints
For prints you are not currently displaying:
- Store flat (never rolled — rolling can crack the pigment surface)
- Interleave with acid-free tissue paper between each print
- Store in a flat archival box or portfolio case
- Keep in a dry, dark location at stable temperature
- Handle only at the edges — oils from skin can damage the pigment surface over time
Properly stored Ebru on quality paper can last for centuries — as the Ottoman museum pieces that inspired our practice demonstrate. The choices you make about framing and storage now will determine how your work survives for those who encounter it decades hence.
