Drum scanners and flatbed scanners are two different types of scanners used for digitizing images. Drum scanners are high-end devices that use a rotating drum to scan images with high precision and resolution. They are capable of capturing a wide range of colors and tones, making them ideal for high-quality printing and publishing applications. On the other hand, flatbed scanners are more commonly used for everyday scanning tasks. They are typically less expensive and easier to use than drum scanners, but they may not produce the same level of detail and color accuracy. Flatbed scanners are also more versatile, as they can scan a variety of materials, including books, documents, and photographs, while drum scanners are mainly used for film and transparency scanning. Overall, the choice between a drum scanner and a flatbed scanner depends on the specific needs and requirements of the user.
Scanners are an essential part of modern-day technology. They are used to convert physical documents into digital format. There are two types of scanners that are commonly used- Drum Scanner and Flatbed Scanner. Both have their unique features and are used for different purposes. In this article, we will discuss the difference between Drum Scanner and Flatbed Scanner.
A Drum Scanner is a specialized type of scanner that is used to scan high-quality images. It consists of a rotating drum that holds the document to be scanned. The drum rotates at a high speed while the scanner head moves back and forth across the drum, capturing the image. Drum scanners are used for high-end scanning applications, such as printing, publishing, and graphic design.
A Flatbed Scanner is a scanner that has a flat glass surface on which the document to be scanned is placed. The scanner head moves back and forth across the glass surface, capturing the image. Flatbed scanners are commonly used for scanning documents, photographs, and other flat objects.
Drum Scanner | Flatbed Scanner | |
Scanning Quality | Drum scanners are capable of producing high-quality scans with a resolution of up to 20,000 dpi. | Flatbed scanners are capable of producing good quality scans with a resolution of up to 4,800 dpi. |
Speed | Drum scanners are slower than flatbed scanners as they require more time to scan an image due to their high scanning quality. | Flatbed scanners are faster than drum scanners as they can scan an image quickly. |
Size of Documents | Drum scanners can scan large documents up to 12 inches in width and 18 inches in length. | Flatbed scanners can scan documents up to 8.5 inches in width and 11 inches in length. |
Cost | Drum scanners are expensive and are usually used by professionals in the printing and publishing industry. | Flatbed scanners are affordable and are commonly used by individuals for personal use. |
Image Distortion | Drum scanners produce less image distortion as the document is held tightly against the drum during scanning. | Flatbed scanners can produce image distortion as the document may not be held tightly against the glass surface during scanning. |
