The difference between the scanner and the copier in paper stability is different from the U-feed of the traditional copier through the automatic document feeder. The paper feed path of the scanner adopts a straight channel design, which is obviously smoother when passing through paper or other media. This article will introduce you to which brand of scanner.
Many scanner users are accustomed to adjusting only the resolution and scaling during scanning. The rest use the default settings. After scanning, the image editing software is used for color adjustment. However, the actual scanner collects more information than the generated scanned image file. This extra information is available at the time of scanning, but the resulting scanned image does not exist. Therefore, the adjustment function of the scanning software is fully utilized, and the image adjustment is performed before the scanning, but the scanning effect closer to the real image is obtained.
The color of the scanner is mainly a mixture of red, green and blue. Some scanners provide adjustments for each of the three basic colors, and adjusting the saturation of the three primary colors gives a filter-like effect. The color adjustment can also make up for some shortcomings of the original film, and can also compensate for different printing processes. But increasing color saturation often makes skin tone look unnatural.
Scanning supports automatic deskew, automatic cropping, and brightness and contrast settings. This “perfect page scan†feature makes scan results more accurate and readable. The included background removal and anti-scanning function can more clearly restore the key text information on the ticket when scanning invoices and courier documents. Output files can be saved in JPEG, TIFF or PDF format for flexible archiving.
