Large Format Flatbed Scanner

Out of all the different types of large format scanners, flatbed scanners are the ones that are most widely used. That is because they can be used for a number of purposes. They can also be used in a number of different ways. And this is why these scanners are one of the most versatile types available in the market. For instance, users can scan the pages right from their book; however, in the process, they would not need to tear down the pages.

Large format scanners are also different from other scanners in the sense that they do not scan papers only. They can also be used to scan, for instance, botanical specimen (such as dried up flowers and leaves).

Most large formal flatbed scanners offer optical resolution of 2400 x 4800. This is much higher than most other scanners. Like others, they work with a special type of software. This software is offered – absolutely free of cost – at the point of purchase of the scanner. However, a few resellers often intentionally do not include the software so that they can sell it later at a high price. As a result, consumers need to be extremely cautious in collecting the right software at the point of purchase.

The color depth provided by the scanners is also very high (about 48-bit). They also offer 16-bit gray scale depth. However, the details vary with scanners from different brands. All these scanners usually provide optical density of around 3.8 – which ensures extremely accurate and crisp images. The quality of the images is further enhanced by auto focus optics system and alternated color CCD.

When buying out the scanners, consumers should pay attention to the surface of scanning. They should buy only those that match their specific requirements. Usually, scanners with large surfaces have a very high price. For most people, a scanner with A3 sized scanning surface (that measures about 12.2 by 17.2 inches in size) is sufficient. Other essential items that are also offered for free are: transparency adapter, user’s manual and documentation, power cable, and USB cable. Almost all printers of reputable brands are compatible with both PC and Mac.

The users of large format flatbed scanners are usually for profession photographers, graphic artists and people who are willing to spend a lot of money for their scanning needs. Therefore, the prices of these scanners are quite high. Even a scanner without all the high end features from a reputable brand – such as , Altek Corporation, Hewlett-Packard, ACTion Imaging Solutions, Vidar Systems, and Purup-Eskofot Inc. – costs at least $2500. However, by investing on such printers, the user can also benefit from high quality scanning solutions. The scan speeds are also very high (about 2.7 milliseconds per line). This is due to the moving carriage type Transparency Unit (TPU) that includes extremely efficient lamps for scanning films easily. Time can be further saved by the automatic document feeder which provides users with the option of scanning several pages simultaneously. This feature is certainly helpful when the user is left with the job of scanning a large number of pages – such as an entire book.

The transparency adapter – a feature that is found in most large format flatbed scanners – allows the user to take detailed scans in a relatively short period of time. However, this feature works with only papers with sizes of 5 inches x 4 inches.

The scanners may be extremely sophisticated but they are very easy to use. However, there is a doubt on the durability of these scanners. And even though their prices are extremely high, their manufacturers offer warranty of one year only. Even then, a few brands offer no warranty at all. As a result, they are suitable for only those consumers whose purchase decisions will only be influenced by the quality of the images scanned and not by the costs.
