    Types:

    Large format scanners come in various different designs that are suitable for different purposes. Among them, the four most popular designs are discussed here –

     

    1. Flatbed Scanners: Flatbed scanners (also known as reflective scanners) abide by the laws of reflection. After assessing the color and intensity of the light, this type of scanners scan one line at a time of the given object. Flatbed scanners are appropriate to scan opaque and flat objects. You could find two types of flatbed scanners in the market – CCD scanners and CIS scanners.

     

    2. Video Digitizers: Video digitizers are used in video cameras and they use the similar technology of CCD arrays like flatbed scanners. Video digitizers are inexpensive and efficient.

     

    3. Drum Scanners: Drum scanners are the most expensive type of scanners but they provide excellent quality and superior speed. They are normally used for the purpose of color separation.

     

    4. Transparency Scanners: Transparency scanners use high-quality and expensive software technology and are specifically built for professionals.

     

    Who uses them:

    As large format scanners provide a wide range of benefits, many professional domains take advantage of these beneficial features and use them for the betterment of their respective businesses. The following are four such professional domains –

     

    A. Architecture: Architectural drawings can be really intricate sometimes, and are usually made on large sheets of paper. Scanning such drawings is really difficult for regular scanners but without scanning, paper occupies a lot of storage space. Because of their large size, such paper is also difficult to maneuver. Large format scanners are capable of scanning such paper while maintaining accuracy, resolution, and precision and store them digitally, eliminating the risk of the valuable documents getting destroyed.

     

    B. Civil Engineering: Similar to architecture, civil engineering is also about large and intricate drawings and designs. A technology known as Computer Aided Design (CAD) is used for designing nowadays. Large format scanners can efficiently make immaculate CAD scans and hence, they play a crucial role in modern day civil engineering.

     

    C. Archaeology and History: History and archaeology deal with ancient documents, paintings, writs, and books. Some of these objects are extant for several centuries and are of utmost historical significance. As all of these materials are susceptible to various kinds of damage, historians now tend to use large format scanners to store them digitally if the original documents get destroyed for some reason. Also, these historical papers are very large, and cannot be scanned too well using an ordinary scanner.

     

    D. Art and Craft: Artistic designs are also made on paper that is large in size. Artists tend to use large format scanners as these scanners provide speed, accuracy in matching colors, high resolution, and the usability of software.

     

    Step-by-Step User Guide

    One of many benefits that large format scanners provide is its user-friendliness.

    A large format scanner can be operated by following five simple steps –

     

    a. Document evaluation: As large format scanners are used to scan multifarious documents, it is important to evaluate it before putting it inside the scanner.

     

    b. Document arrangement: After getting done with the evaluation process, now the documents have to sort out in a systematic arrangement to avoid    any kind of confusion.

     

    c. Equipping the feeder: After evaluating and arranging the documents, it has to be placed in the feeder properly.

     

    d. Calibration: Using specific software such as Adobe Photoshop, calibration of the documents can be done very easily.
