Having a desktop scanner can be a convenient piece of equipment. It can create a digital image of a physical document, such as a check, and even sign a document. But there are a few things you should know before you purchase one from scanner de bureau, so you can be sure that you’re getting the best one for your needs.
The drum scanner is a special scanner that produces high-resolution images. The resolution is usually around 6000 dpi. However, in some cases, they can go up to 11000 dpi. This makes them a good choice for professionals and publishing houses. However, they are not suitable for home use, as they can be costly.
To produce high-resolution images, the drum scanner uses a photomultiplier tube. Photo multipliers are a type of light sensor much more sensitive than CCD sensors. They can also generate higher resolution and better dynamic range than CCD sensors.
These sensors are used to scan transparent and reflective media. In addition, using the photomultiplier tube, the drum scanner can achieve resolutions higher than those produced by CCDs. This is because photo multipliers are more sensitive than photodiodes.
The drum scanner is also able to produce images with excellent tonality. The shadow details in an image can be minutely resolved. This is especially useful for enlargements.
Flatbed scanners are the most popular type of scanners available today. These devices are great for scanning documents and photos. The best flatbed scanners offer a high-quality scan. They are also inexpensive. Compared to sheet-fed scanners, flatbed scanners are also more versatile. For example, they can digitize objects that are too thick or too opaque to be handled by sheet-fed scanners.
Flatbed scanners have become popular in the 2000s. They were previously only found in print shops. Fortunately, these devices have become more affordable and are now available to consumers. They can be found for less than $100. Besides, most flatbed scanners have an adjustable lid, making it easy to scan thicker objects.
Flatbed scanners can also capture 3-D objects. You place the thing on the scanner bed during the scanning process and then close the lid. This reduces the risk of document damage.
Flatbed scanners are ideal for scanning books. They are the easiest way to scan books, especially very old books.
