Storing Blueprints

 

Proper storage of architectural blueprints is crucial for preserving these valuable historical and technical documents. Whether you’re an architect, historian, or property owner, following the right preservation techniques will ensure your blueprints remain legible and intact for generations to come.

Environmental Controls

The environment where you store blueprints plays a critical role in their preservation. Maintain a stable temperature between 65-70°F (18-21°C) and relative humidity between 45-50%. Fluctuations in either can cause paper deterioration and promote mold growth. Install climate control systems and regularly monitor conditions using environmental meters.

Storage Solutions

Store blueprints flat whenever possible in acid-free archival boxes or metal flat files. If flat storage isn’t feasible, roll blueprints around archival tubes at least 3 inches in diameter – never fold them. Place acid-free tissue paper between prints to prevent transfer and abrasion. For oversized prints, consider custom-sized archival boxes or map cases.

Handling Guidelines

Always handle blueprints with clean, dry hands or wear white cotton gloves. Support the full width when moving prints to prevent tears and creases. Never use tape, staples, or adhesives on original blueprints. If repairs are needed, consult a professional conservator.

Digital Preservation

Consider creating high-resolution digital scans of your blueprints as backup copies and for easy reference. Store digital files in multiple locations and formats, updating them periodically as technology evolves. However, proper physical storage remains essential for original documents.
