Thread sewn binding

Thread sewn binding is the oldest type of book binding. Accordingly, many methods and types have developed over the centuries, such as saddle stitching, block stitching, alternate stitching, and many more.

In thread sewn binding, the folded sheets are sewn together at the spine to form a book block. The thickness of the thread must always match the paper of the book block. Four (in rare cases also eight) sheets are sewn together in each case to form a layer and then knotted together to form a book block. It is important that the stitching tapes are not pierced during stitching so that there is no tension when the spine is rounded later. Stitching tapes can be made of parchment, leather or fabric, among other materials.

TWAIN

TWAIN, an acronym for Technology Without An Interesting Name is a standard for the application program interface (API) between input devices like book scanners and applications which control the image input device such as capture software. Using a TWAIN-compliant application like open office and TWAIN-compliant scanner with TWAIN-compliant drivers allows users to operate scanners in a similar way.

Book2net scanners are fitted with optional TWAIN drivers giving users the possibility to log in with TWAIN-compatible applications like Adobe, initiate scanning via Adobe scan command, then book2net capture software will start scanning with specified settings. TWAIN functions with TIFF (Tagged Image File Formats) file and is appropriate for doing optical character recognition (OCR) to create text output.

TIFF

TIFF is a computer file format used for storing very large, high-quality images. The TIFF format specifies the number of tags used to store information about an image as well as allowing users to define their own tags. TIFF images are available in black and white bi-level, grayscale, RGB as well as a palette or indexed images. In addition, TIFF file formats support images in YCbCr and CMYK formats as well as color depths ranging from 1 to 48 bits.

TIFF file format is highly used in graphic applications, image manipulation programs, 3-D image applications, optical recognition software, desktop publishing as well as scanning and software applications. Other versions such as GeoTIFF are used to store Geo-referenced raster images.

Images saved in TIFF are often very large, with a maximum size limit of 4GB, therefore creating the need to compress them during transmission or convert them to other file formats such as JPEG. Book2net Easy Scan Professional capture software supports TIFF file formats which can be easily identified by a.tiff or a.tif file extension.
