How to adjust the scanner when scanning hand-drawn manuscripts?

How to adjust the red, green and blue of Kodak scanner

Adjust by scanning software settings:

Open the scanner software and select "Histogram Adjuster" in the adjuster, as shown in the figure:

2. It can be seen that the interface has four channels, 1 red, green and blue mixed channel and three red, green and blue monochrome channels. Input value and output value can be set for each channel. The input value is the original data obtained by scanning, and the output value is the result of software calculation. (Note: The data range of each channel is 0~255, in which the larger the value, the stronger the color. )

3. For example, if the red in the picture is too bright, the value of red can be increased appropriately, and if the image is red, it can be brightened. After adjustment, the scanning effect is better, and you can master it by scanning several times. As shown in the figure:

The advantages of the above method are convenience, rapidity and zero cost; But the disadvantage is that it is a test of eyesight and mediation experience, and it is very subjective. What's more, with the increase of scanning frequency, the light source of the scanner gradually ages and the scanning performance changes, and the adjustments made at regular intervals will fail again. In order to obtain better scanning color reproduction effect, the following is the scanner color correction card, which is the only recognized mature scanner color correction scheme in the world.

Second, use the scanner color correction card to adjust the color of the scanner:

Brief introduction of scanner color calibration card;

Scanner color correction card is a kind of photo containing color information, which was originally invented by Kodak Company. Together with the color value data file of color correction card, it is used for scanner color management, making scanner color characteristic curve ICC and correcting scanner color deviation. Up to now, it has a mature application history of several decades, and it is the only effective and mature color management scheme for scanner color correction. Later, ICC was derived to make the color characteristics of printers and cameras, and the color deviation of equipment was corrected by color correction software such as MonacoEZcolor, ProfilePrism, Vuescan and Silverfast.

Why do you want to correct the color?

Because even if it is a brand-new scanner, each scanner will present different colors because of the differences in characteristics; Even the scanner that has been calibrated before leaving the factory will change its scanning color with the passage of time because of the aging of the light source, which is the same as the aging and yellowing of fluorescent lamps at home. The purpose of scanner color calibration is to make different scanners or scanners with different aging periods perfectly restore the true color of the scanned object! Therefore, we not only need to correct the color of the scanner, but also must do it regularly to keep the accurate color!

The steps of color correction are simple:

Close the color management of the scanner and scan the color correction card;

The scanned TIF picture and the color value data of the color calibration card are imported into the color calibration software, and the software automatically calculates the color characteristic curve ICC of the equipment. It is very simple, easy to learn and use.

When scanning again, set the color management of the scanner to embed ICC scanning to get more realistic photos.

Comparison of color correction effects:

Comparing the scanned pictures before and after color correction, we can see the yellow of banana, the red of tomato, the yellow of lemon and the green of grape, and we can obviously see the improvement effect of color restoration after color correction.

1, of course, can be adjusted by the color scale curve of PS. At that time, this method required rich experience and color recognition ability, which was subjective and unreliable.

2. It is suggested that you use the scanner color calibration card to calibrate the scanner, make the scanner characteristic curve ICC, and call ICC to scan the manuscript, so as to restore the true color of the manuscript and obtain ideal results. This method is international and effective.

How to operate the scanner

The specific operation method of the scanner is as follows:

Tools/raw materials: tink pad 14s, Windows 10.

Correct use of scanner

New employees often come to the office: "How to use this scanner?" Let me introduce you to the correct usage of the scanner. I hope I can help you. Welcome to read!

Correct use of scanner

Scanning image

After installing the driver, the application software is used to obtain the scanned image of the scanner. The simplest and most convenient way is to use the "drawing" software that comes with Windows system. Naturally, you can also use professional graphics and image software, such as Photoshop, to obtain scanned images. Let's take "Drawing" software as an example to illustrate how to obtain scanned images.

(1) Under the WindowsXP operating system, click Start → All Programs → Accessories → Drawing to open the drawing software window.

(2) Click the "From Scanner or Camera" command on the file menu bar to pop up the scanner window.

(3) Windows have four options, corresponding to the type of manuscript we want to scan. If you want to scan a color photo, please select the "Color Photo" item, put the photo in the scanner, cover it, and then click the "Preview" button. At this point, the scanner starts to preview, and the pre-scanned picture appears in. Preview box on the right.

(4) Move and scale the rectangular box in the preview box to an appropriate size and position, and select the area to be scanned. After selection, click the "Scan" button, the scanner will start scanning, and the screen will display the scanning progress.

(5) After scanning, the picture will appear in the small picture editing area of the Drawing software window, and you can modify and save the picture.

Scan text

The scanner also has a very useful function, that is, the opticalcharacterrecognition (OCR) function, which transforms printed articles into editable texts by scanning, greatly facilitating text entry workers. To realize character recognition, OCR character recognition software should be installed in addition to the scanner driver and scanner application software.

First, the manuscript should be scanned and then identified. Generally speaking, there are the following steps:

(1) Scan files. In order to use OCR software for character recognition, you can scan the manuscript directly in OCR software. After running the OCR soft servant, the OCR software interface will appear.

Place the manuscript to be scanned on the glass surface of the scanner, so that the side to be scanned faces the glass surface of the scanner, with the tip of the manuscript facing down and aligned with the edge of the ruler, and then cover the scanner for scanning. Click the "Scan" button in the window to enter the scanning driver software for scanning, and its operation method is similar to scanning pictures. The scanned document image appears in the OCR software window.

(2) Scale the picture appropriately. After scanning the document, the picture of the text to be recognized that just appeared in the window is very small. First, select the "Enlarge" tool to enlarge the picture appropriately to make it clearer. If necessary, you can also select the Reduce tool to reduce the screen appropriately.

(3) Adjust the picture. All kinds of OCR software provide rotation function, so that the picture can be rotated at any angle. If the text screen is tilted, you can choose the Tilt Correction tool or the Rotation tool to adjust the screen.

(4) Select the recognition area. When recognizing, select the "Set Recognition Area" tool to frame the area to be recognized on the text screen. At this time, you can also frame multiple areas according to the screen situation. If it is full-text recognition, there is no need to set the recognition area.

(5) recognize the text. Click the "recognize" command, then OCR will segment the text first, and then recognize it, and the recognized text will be gradually displayed. After the general appraisal is completed, turn to the "manuscript proofreading" window.

(6) proofreading of manuscripts. All kinds of OCR software provide the function of proofreading and revising manuscripts. Possible wrong words are identified, displayed in bright colors, and can be modified. Some software's text proofreading tools can provide several words with similar glyphs to choose from.

(7) save the file. Users can store the recognized file as a text (TXT) file of Word or an RTF file.

This cartoon was scanned by a scanner. How to adjust it?

Generally, scanners are equipped with corresponding software.

I don't know what scanner you are using!

Did you scan the black-and-white manuscript or the color manuscript?

Generally speaking, scanners have scanning modes, such as fine scanning, black and white scanning, grayscale or photo.

If you print a color manuscript, it will be beautiful in color when scanned. If it is black and white, I usually use gray scale.

Clarity has nothing to do with chromaticity. This definition is only affected by the resolution. If you don't want it to be too big, 300DPI will do ~

Generally, everything scanned by a scanner needs PS post-processing, so don't be lazy ~
