Best Squeegees and Drying Screens for Fiber Prints

What material properties should a squeegee possess to avoid scratching delicate fiber-based photographic paper?

A squeegee must possess a low coefficient of friction and a smooth, non-porous surface to glide across the wet, swollen emulsion of fiber-based paper. Silicone blades excel here because they are naturally hydrophobic and resist the tackiness that often develops when paper fibers hydrate. A high-quality blade like the archival-grade blades produced by Kaiser Fototechnik provides the necessary flexibility to conform to the paper surface without dragging or creating localized pressure points that lead to physical abrasions.

The nuance lies in the edge profile of the blade. Even a soft material can cause damage if it has a sharp, molded seam or a jagged edge from improper trimming. Practitioners should inspect the blade edge under a magnifying glass for imperfections before use. A perfectly square, polished edge is the standard for preventing the micro-scratches that often ruin high-gloss fiber prints.

How does the choice of squeegee blade durometer affect the removal of surface water from fiber prints?

A lower durometer blade, such as one rated at 40 Shore A, allows for greater surface contact, which effectively wicks away moisture without forcing water into the paper base. Higher durometer blades often miss surface pockets, requiring multiple passes that increase the risk of physical damage to the delicate emulsion.

What are the primary differences between silicone and rubber squeegees regarding print longevity and chemical resistance?

Silicone squeegees are chemically inert, meaning they won't react with the fixer residues or silver halides present in the emulsion during the final wash stages. Rubber, by contrast, frequently contains sulfur-based vulcanizing agents that can migrate into the paper fibers over time. This chemical leaching is a common cause of yellowing or "fogging" in fiber prints stored in archival enclosures. Using a silicone blade prevents this cross-contamination, protecting the long-term integrity of the silver image.

An exception exists with high-end, synthetic EPDM rubber squeegees, which are engineered to be sulfur-free and stable. While these are safer than standard natural rubber, they still lack the extreme temperature resistance and surface smoothness of medical-grade silicone. For the most critical exhibition prints, silicone remains the industry standard to prevent any potential chemical interaction with the print surface.

Which types of drying screens provide the best airflow to prevent fiber prints from curling during the drying process?

Open-weave fiberglass screens with a mesh count of 12 to 18 threads per inch provide the most consistent airflow for even, tension-free drying.

• 15 threads: This specific density balances structural support with maximum air circulation to prevent moisture pockets.
• Fiberglass mesh: This material remains dimensionally stable when wet, preventing the sagging that causes prints to pool water.
• Raised frames: Elevating the screen at least 5 centimeters off the table surface facilitates convection currents beneath the print.
• Horizontal positioning: Keeping the screen perfectly level prevents gravity from pulling moisture toward one edge, which causes uneven drying and curling.

How should drying screens be maintained to prevent the transfer of contaminants or dust to wet prints?

Wipe screens down with a damp, lint-free microfiber cloth after every session and store them vertically in a dust-free cabinet to prevent debris accumulation. Many people assume that a quick rinse with tap water is sufficient to clean a screen, but tap water often contains mineral deposits and chlorine that can crystallize on the mesh. These dried minerals act like sandpaper against the back of the print, causing fine abrasions that become visible once the print is mounted or framed. Always use distilled water for the final rinse to keep the surface pristine.

What is the recommended technique for using a squeegee on fiber prints to ensure uniform water removal without damaging the emulsion?

Use a single, fluid motion starting from the center of the print and moving toward the edges to push water out without trapping air bubbles.

• 45 degrees: Hold the squeegee at this angle to the print surface to maintain optimal pressure and fluid displacement.
• Light pressure: Apply only enough force to clear the water, as excessive weight causes the blade to chatter and skip.
• One direction: Move the squeegee in a single stroke across the surface to avoid re-depositing water or scratching the emulsion.
• Clean edge: Make sure the blade is wiped clean with a damp sponge between every single pass to remove accumulated debris.

Are there specific screen mesh materials that are safer for fiber-based papers than others?

Yes, fiberglass mesh is safer than nylon or metal because it is chemically inert and non-absorbent. Nylon mesh can harbor moisture and bacteria, while metal screens often corrode, leaving permanent stains on the paper base. Fiberglass maintains its shape under tension, which is vital for preventing print distortion.

How does the orientation of a print on a drying screen influence the final flatness of the dried image?

Placing the print face-down on the screen minimizes curling by allowing the paper base to dry at a rate closer to the emulsion side.

Use these times as a baseline for your ambient humidity levels, adjusting the duration if your work environment exceeds 50 percent relative humidity.
