We demonstrate, that Magnetic-Resonance-Microscopy is even able to visualize printed letters at thickness\u2009&lt;\u200930\u2009\u00b5m on superposed paper-sheets. The physical-technical methodology is based on prototype hardware installed as insert on a human MR-scanner relying on strong magnetic and gradient-fields with sensitive radiofrequency-sensors. A negative contrast mechanism, adding MR-visible chemically-inert liquid, is necessary, its removal being potentially harmful to valuable paper sheets. For visualization of text firstly the letter thickness (\u224220\u2009\u00b5m) and exact positions were determined before adjusting optimized resolution and field-of-view (FOV) in measurement and reprocessing of 3D-data for slice-positioning in the plane of the paper sheets. The advantages of a semi-automatic data processing method for visualization on the bowed paper-sheets are demonstrated. In contrast to micro-Computed tomography based on absorption contrast, MR-microscopy can visualize non-metallic printed letters and offers higher spatial resolution than Terahertz imaging. As a preclinical MR-imaging tool (with limited FOV) it is more widely available than neutron-tomography. The reported MRM-technology might be also of interest for radiological high-resolution applications such as MR-based histology.\n                  <\/jats:p>","DOI":"10.1038\/s44172-026-00614-7","type":"journal-article","created":{"date-parts":[[2026,2,25]],"date-time":"2026-02-25T09:36:33Z","timestamp":1772012193000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Visualization of text on bowed sheets via High-resolution 3D-Magnetic Resonance Micro-imaging for potential reading of closed books: the proof-of-concept"],"prefix":"10.1038","volume":"5","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2190-5242","authenticated-orcid":false,"given":"Andreas Georg","family":"Berg","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9982-432X","authenticated-orcid":false,"given":"Alexander Karl","family":"Seewald","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2026,2,25]]},"reference":[{"key":"614_CR1","unstructured":"Pain, S.
