Height compensation

Book cradle

In order to ensure a true-to-scale, distortion-free high-quality scanning of bound originals, a flat surface of the original is necessary. Professional systems therefore have adjustable or self-adjusting book cradles that automatically compensate for the difference in height between the halves of the original during page turning.

Book2net systems therefore offer book cradles with self-adjusting technology or individually controllable support plates, depending on the requirements.


Glass plate

In order to scan books of different thicknesses gently and efficiently, even with glass plates, professional systems have a height adjustment system for the glass plate that allows the pressure and travel paths to be set precisely to the book thickness.

This is used in particular with semi-robotic high-performance scanners such as the book2net Cobra, Flash, Mosquito, Hornet and Dragon.

Hybrid scanning systems

Extensive digitization projects, in which a large number of different documents are to be scanned gently and efficiently at the same time, are often faced with the problem of finding the optimal scanning systems in terms of quality, workflow and cost efficiency. 

Therefore, at book2net, we have developed versatile hybrid scanning solutions for our customers. These are particularly suitable for the demanding requirements of retro-digitization projects in archives, libraries and digitization centers and enable the document-friendly, user-friendly and productive digitization of both bound and stapled templates as well as loose sheets.

Depending on the project requirements, we will put together a tailor-made package consisting of a book2net planetary book scanner (A1 / A2) for fragile, bound or stapled originals and an A3 SCAMIG document scanner for single sheets or loose stacks of sheets. In this way, the advantages of two scanning worlds are ideally combined: contactless, gentle incident-light digitization with the speed and high throughput of feeder scanners.

The scanning software of the book scanner serves as an interface for both scanners. This means that within the scan software you always receive all scans from both devices in the correct order and can export them together and feed them into further workflows. This eliminates time-consuming work steps such as merging individual scans from different devices and increases productivity significantly without compromising the quality and care in handling your documents.

Homogeneous light

Homogeneous = equal. Homogeneous light, or also homogeneous illumination, refers to the uniform and shadow-free exposure of a room or an object. Especially when digitizing books, homogeneous lighting is crucial to avoid shadowing in critical areas such as edges and book folds and to achieve a high-quality scan result.

Book2net therefore uses Fresnel lenses for homogeneous illumination, which have proven particularly useful in automotive lighting technology, where uniform illumination of the surroundings is vital.

Historical formats (paper formats)

Just like book formats, paper formats also vary considerably from one another around the world to this day. This is mainly due to their historically determined different creation and manufacturing processes and technological developments.

In the 14th and 15th centuries, for example, sheet sizes of 43 × 30 cm were common in what is now Italy, Switzerland and Germany, which roughly corresponds to today’s DIN A3 format. This size was an easily manageable format during the manually performed process of paper making.

At the same time, however, the first paper mills were already being built for the mass production of paper. Historical paper formats were therefore always derived from the sheet format of the respective manufacturer. So-called quarto formats (i.e. a quarter of the sheet, produced by dividing it twice) or octave formats (analogous to this, an eighth of the sheet) were common. However, there was no standardization. Historical formats also differed fundamentally in page proportions from today’s standard formats. Commonly, the sheet format was 3∶4 pages. If you fold such a sheet, you get a sheet with proportions 2∶3, and if you fold it a second time, you get another one with 3∶4 pages, and so on. Thus, the quarto format usually had a format of 3∶4, the octavo format of 2∶3.

Different aesthetic properties and suitability for certain purposes were attributed to these formats. For example, the 3∶4 quarto format was considered soft and friendly, while the narrower 2∶3 octavo format was considered more austere. When used as a book format, the larger and wider quarto format was preferred for bound books placed on a table. The handier 2∶3 inch format, on the other hand, was suitable for books that were held in the hand. Even today, paperbacks typically have a narrow format close to the 2∶3 aspect ratio.

In places, such as libraries, 19th century formats are still in use today. Some values have changed over time, sometimes by more than an inch.

HS Code

Harmonized systems codes (HS codes) are standardized numerical ways of classifying globally traded products. They are widely used during export and import goods. Administered by the World Customs Organization and updated every five years, HS codes are used by customs authorities throughout the world to identify products when assessing internal taxes and gathering data. The book2net book scanners fall under HS Code 84718000.
