PRACTICAL METHOD OF USING SCANNER Ⅱ

(5) Store curves and load scanning software

Sometimes, in order to get the best color and scanning contrast, take a low-resolution scan first, open it in Photoshop then, and use Photoshop's curve function to improve color and contrast. Save the curve and load it back into the scanning software. The scanner will now use this color correction curve to create a better high-resolution file. If several images are scanned with a similar gamut range, the same curves can be used, and curves can also be stored frequently and loaded back as needed.

 

(6) Place the scanned object according to the required effect

In the actual process of using images, it is sometimes hoped that images with oblique effects can be obtained. Many designers often input images into computers through scanners, and then use professional image software to rotate the images to achieve the rotation effect. However, this process is very time-consuming, and the image quality will decline according to the angle of rotation. If you know in advance how the image is placed on the page, then using the protractor and the bottom edge of the original to place the original at a precise angle on the cylinder and the platen, you will get the highest quality image without rotating in the image processing software.

 

(7) Find the best scanning area on the glass plate

In order to obtain the best image scanning quality, find the best scanning area of the scanner, and then place the object to be scanned here to obtain the best and most fidelity image effect. The specific searching steps are as follows: first, set all controls of the scanner to automatic or silent state, select all areas, and then scan a blank, white or opaque sample with low resolution; then use Photoshop, a professional image processing software, to open the sample manuscript. Use the averaging command (Equalize menu item) in the software to process the sample manuscript. After processing, you can see where there are cracks, stripes and black spots on the scanner. You can print this document and cut out the best area (that is, the most stable area) to help place the image.

 

(8) Use transparent sheet fittings to obtain the best scanning effect

Many flatbed scanners are equipped with transparency fittings placed at the top of the scanner bed. In order to obtain the best scanning of transparent films or slides, remove the pictures from the rack and slide mounting rack and mount them on the glass scanning bed with the reverse side facing down (the reverse side is usually a rough surface). Cut out the mask with black paper and cover the entire scanning bed except where the manuscript is set. This will reduce glare and overexposure during scanning. Similarly, when scanning a three-dimensional object, cover the cover of the scanner with an object with a strong contrast in color with the object you are scanning. This will help you to select it more easily with the PhotoshopColorRange tool.

(9) Maximize that color gamut of the scanned image

In order to make full use of the 30-bit or 36-bit scanner to increase the color range, the scanner software (such as FotoTune of Agfa) or other company's software should be used to adjust the color as much as possible. Because Photoshop software is limited to 24-bit images, images may be inserted in the widest color gamut range.

 

(10) Scan printed matter with no screen printing technology

When scanning printed matter, there will be screen flowers in the continuous tone of the image. If the scanner does not have a screen removal function, try to find the resolution that minimizes the screen size. Often, the same or double resolution of the screen line of printed matter may work. Once you get a fairly good scan, use Photoshop as a Gaussian Blur filter (with a setting of less than 1 pixel) to slightly soften the mesh until you cannot see it. Then use Unsharp Mask to sharpen the image back. Scanning can also be improved by slightly rotating the image because the continuously adjusted screen angle is changed. For black-and-white images, the rotation of 45 degrees is just right. For CMYK images, experiments will be required.
