This article discusses the creation of a 3D archive and physical copies of paper reliefs (estamages). A matrix of the estampage is fabricated by the combined use of 3D scanning technology and additive technologies which can then be used for the documentation and conservation of the original estampage. In order to digitize the relief, an optical 3D scanner based on structured light was used and the processing of the 3D model is discussed in detail. Scanning data is uploaded into the microprocessor of a 3D laser printer using stereolithography technology which then creates a conservation matrix. The accuracy of relief reproduction is assessed by comparing its 3D model with 3D models of replicas obtained with the help of 3D printers. The experimental research showed that it is possible to create 3D archives and reproduction of reliefs. This approach is fundamentally new in the practice of museums and archives.

The ability to determine the condition of paper (e.g. its brittleness) and its permanence is a need in libraries and archives. This study investigates various bend tests and applies these tests to aged paper with the goal of finding easy, non-destructive tests to determine the mechanical properties of paper. The cantilever test was previously shown to accurately assess mechanical properties of paper-based materials, such as elastic and bending moduli as well as the bending length. This work investigates the hanging pear loop and clamped fold tests and compares the results with those found with the cantilever test. The results show that the strain and curvature induced by the two tests are much larger than those experienced in the cantilever test. This large strain and curvature induce plastic behaviour and make the hanging pear loop and clamped fold tests inappropriate for use on paper-based materials.

Perforated cardboards were common and economic supports for embroidery in the Victorian Era. Despite their popularity, they had a brief life and are almost forgotten today. Different types of cardboard were chosen according to the materials and techniques to be applied. This article presents nineteenth century documentary sources on perforated cardboard and its use in various objects of everyday life. The types of cardboard, commercialization, decorative techniques and motifs and applied materials will be discussed.
