How to use the scanner, how to use the scanner

In the office, the scanner can also play its role. With the help of the scanner, people can scan the file more easily and conveniently, and effectively improve the work efficiency. But how to use the scanner? Those who have not used this product will be curious about its use function. In order to solve this problem, Xiaobian has made a description of how to use the scanner.

First, how to use the scanner

1. Determine the appropriate scanning method

The scanner can scan photos, text, images, etc. Different scanning objects have different scanning methods. First open the scanner's driver interface, and then you will find that the program provides a total of three scanning options, of which black and white is suitable for originals with black and white, the scanner will display black and white pixels in one bit, which will save a lot of money. Disk space. Grayscale is suitable for text and text samples with both images and text, scanning for text of this type and images with multiple gray levels. The photo is suitable for scanning color photos and sampling and storing multiple levels of red, green and blue channels.

2, optimize the scanner resolution

The higher the scanning resolution, the higher the sharpness of the image it gets, but considering that if the resolution of the output device is exceeded, the clear image will not be printed, but it will take up disk space and have no practical value. For example, prepare a printer output with 600DPI resolution, scan at 600dpi, and if possible, scale down large images after scanning. For example, scan a 4*4 inch image at 600dpi and reduce it to 2*2 inches in the grouping program. Its resolution is 1200dip.

3, set the scan parameters

Before the scanner is used, it will have the function of pre-scanning. It is scanned according to the default scanning parameter value of the system. The effect may be different for different scanning objects and different scanning methods. Therefore, in order to be able to move high image scanning quality, we can manually adjust the parameters. For example, when the brightness of grayscale and color images is too bright or too dark, you can drag the slider on the brightness slider. Change the brightness.

4, design the size of the file

Regardless of whether the object being scanned is text or photo, all images output by the scanner are images, and the size of the image is directly related to the size of the file. The scanned file can also be set to its size.

5, store the curve and load the scanning software

In order to get the best color and scan contrast, first do a low-resolution scan, open it in photoshop, and use the photoshop curve function to improve color and contrast. The curve is stored and loaded back into the scanning software, which the scanner will now use to create better high resolution files.

Second, the scanner instructions

1, preparation work

Before using the scanner, you should have a preliminary understanding of the basic principles of the scanner, which will help us use the scanner correctly. In order to be able to reflect the image objectively and realistically, it is necessary to ensure that the light can be smoothly scanned onto the manuscript to be scanned, so it is possible to preheat the scanner for a few minutes to ensure that the lamp inside the machine is uniformly illuminated. Its light is in a certain inch of space.

2. Pre-scan step

In order to save the scanning time, some friends will be greedy and will ignore the pre-scan step. In fact, the pre-scan function is necessary to ensure the scanning effect. Good manuscripts pay special attention to high-quality scanning results, and poor quality manuscripts are difficult to achieve good scanning results through software.

3. How much resolution is used?

Many users will want to know how much resolution to scan when using the scanner. In fact, this is determined according to the needs of users. A scanner with a higher resolution represents a sharper image, but it also assumes that the image file is not easy to process. If you want the scanned work to be printed by the printer, consider the resolution of the printer.

How to use the scanner? In fact, the scanner usage is very simple, the scanner uses the above instructions, people who do not understand can learn more about its specific use. There is also a scanner with instructions. If you don't know how to use it, you can understand the manual first, and then follow the instructions to operate naturally.
