Increasing quality and decreasing prices of digital imaging know-how over the past few years have made large format scanning an increasingly affordable and useful way to preserve archive and facilitate reproduction of larger documents. Recent applications of this best large format scanner know-how are far-reaching, including the preservation of historically in the past significant documents and indigenous textiles and clothing, paintings, photographs, maps, blueprints, technical drawings and far more.

The width of the scanner is the most important factor in its cost. Large format scanning devices come in lots of different sizes, usually ranging from 25 inches to 44 inches wide. Popular sizes include 36 inch models that can accommodate engineering drawings, as well as 42 and 44 inch scanners that better match the typical wide format printer sizes. Fortunately, prices for imaging know-how have dropped considerably since 2006, making these larger formats more available. A few models are made in 48 inch and 56 inch sizes.

All of large format scanners are sheet-fed, drawing paper through the device to pass over a stationary scan head. Sheet-fed models take less space than their flatbed counterparts and are limited only by width than length. Some can be fed from rolls as well as individual sheets. However, in case you require to scan a delicate item that could be damaged or distorted when being fed through a sheet-fed device, or something that is thicker than paper, a flatbed large format scanner may be your best bet.

Contact Picture Sensor know-how is best at reproducing fine line details and capturing colors in blueprints, CAD and technical drawings as well as maps. CCD (Charge-Coupled Device) is better at capturing detail in images and other artwork. Also, due to greater illumination and depth of focus, CCD imaging is ideal for scanning heavily creased or folded documents. CIS know-how is usually less expensive than CCD.

Most print applications utilize a resolution of between 200 and 400 DPS, so a massive format scanner that has resolutions of above 400 DPS will usually produce nice results. However, in cases where you require to reproduce fine detail or you intend to enlarge a scanned document, higher resolutions may be preferable.

Large format color scanners, also sometimes called wide format scanners, come in lots of different sizes, types and resolutions. It is vital to fully understand the needs of your organization in order to buy the best for your needs at the lowest cost point. Here are some questions to ask yourself before you start shopping.
