Begin the process of buying high quality flatbed scanners by first performing a simple needs assessment. Consider the following when determining which features to purchase.
Determine first what you are willing to pay and which features are most important to you. This will help in comparing models and will give you an idea of which features are must-have versus really-wants.
Most flatbed scanners have no trouble scanning documents or photographs. Most can scan negatives though an adaptor may be required. If you need the ability to scan three-dimensional objects, there are scanners that can deliver that as well. What you will be able to scan will be limited by the size of the scanner bed. Be aware that some manufacturers produce beds that measure in feet, so size need not be a limiting factor.
Several factors contribute to the overall success of high quality output. All of them depend on the amount of information captured by the scanner. Dynamic range, which is a numeric expression of the difference in the white portion of the image and the darkest portion. The higher the number, the more shades represented in that range. Color depth is also dependent on what the scanner can detect about the subtle shades present in each pixel. The more pixels per inch, the better. High-end input is now around 4800 dpi.
Standards do exist to help define similarities in productivity. Pages per minute (ppm) and images per minute (imp) are standard measurements for how long it takes a scanner to acquire and image.
Before purchasing, check the basics to make sure the new high quality flatbed scanner will work with existing equipment. Check the connection interface. USB is very common, but do not assume that it is standard. Platform compatibility should be considered. Consider whether all the software needed is bundled with the equipment. Look to see if image-editing software, color calibration and driver software are included.
