The black backing trick

Black Backing Technique: A practical digital capture and archiving method used when digitizing translucent or double-sided historical ephemera, such as vintage documents, thin paper prints, or specific transparent media. When these delicate materials are placed directly on a standard copy stand baseboard, light can pass through the paper and bounce back from underneath, causing distracting shadows, bleed-through text, or a severe loss of contrast. Positioning a sheet of matte, non-reflective black material directly beneath the document absorbs this transmitted light, isolating the primary surface details and instantly improving edge definition and text readability.
