Dmax refers to the maximum density rating of an image. While going through our recommended scanners, you might have come across the term Dmax many a time. Dynamic Range –ĭynamic range is the measurement of the difference between the lightest highlights and darkest shadows that a scanner can perceive. In simple terms, more bits means more colors and better quality in your scans. Scan Modeģ6-bit RGB (12 bits per pixel, per color)Ĥ8-bit RGB (16 bits per pixel, per color) The chart below lists the number of colors recognized for each different scan mode. Each pixel can have two states (On or Off) therefore, the number of grayscales or colors that a scanner can recognize is computed by taking the pixel depth as an exponent of two. Now, the number of bits of data captured for each pixel is called pixel depth. The data of each pixel is captured in terms of bits. If the hardware resolution of a scanner is 1200 x 2400 dpi, it means that the sensor has captured data of 1200 horizontal pixels and 2400 vertical pixels. We know that the image is captured in terms of pixels and we also know that the resolution means the measure of pixels horizontally and vertically. Speaking of facts, the interpolated resolution doesn’t add much much to your scan. Usually, the fancy resolution numerical that we see in the product description of scanners is of the interpolated resolution/maximum resolution. They do not add any further detail to the original scan, it simply adds (gradient) pixels based on the mathematical probability of surrounding pixels, horizontally/vertically.
Interpolation is a technique to increase the resolution of an image using a complex algorithm. The optical resolution, Hardware resolution, and the Interpolated resolution. However, the resolution is further categorized into three, based on the type. The quality of your scanned document is directly proportional to its resolution. Resolution is the most important aspect of a scanner. So, let us begin with understanding the things that contribute to perfection when it comes to large format scanning. As long as we (Scanse) are live on the internet, we will not let those small things take over your perfection. These differences might be small but cumulatively they contribute to a greater impact as a wise man once said, Small things make perfection, but perfection isn’t a small thing. When it comes to Good large format scanner, a cheap 200$ machine and a beasty 3000$ machine does the same job but with many fractional differences in almost all aspects.
