Scanner tips

There are many articles on scanners at present, but most of them are introduced from the perspective of the market and vendors. Scanners are most concerned with the specific scanners, especially for professional users. To become a good habit, will achieve a multiplier effect, this article collected some tips for users to use. Find the best scanning area for your platform scanner. Most users may have this misconception that the image is placed on any position in the scanner and the scanned results are the same. This is not the case. The scanner also has the best scanning area, find the best scanning area for your scanner, place the image here for the best, most fidelity image effects, you can save a lot of trouble with post-processing , greatly improving work efficiency. Finding a solution: Set all the scanner controls to automatic, select all areas, and scan a blank sheet of paper at low resolution. Open Adobe Photoshop software, process it with the Equalize command (Equalize menu item), and then you can see where there are cracks, stripes, and black spots on the scanner. We can print out this document and place the best area (ie, the most stable area) in the pen frame next to the scanner to help us place the image for the best scanning results. Rotating the ring image before scanning In image processing, it is time-consuming to perform the rotation process, especially when dealing with high-resolution, large-resolution pictures. The rotation and flipping process will be a long wait, and the size of the rotation angle, It also affects the quality of the image. If we 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 on the roller and the platform at a precise angle will result in the highest quality image, not necessarily in the image processing software. Rotate and waste unnecessary time. Optimize Scanner resolution scan linework, the scan resolution matches the output resolution. For example, prepare a printer output with a resolution of 600 dpi and scan at 600 dpi. If possible, scale down large images after scanning. For example, we scanned a 4*4 inch image at 600 dpi, and it was reduced to 2*2 inches in the build program, and its resolution was 120 Odpi. Enlarging, softening, and then adding a noise-enlarged image is a problem often encountered in image processing. If you enlarge the Photpshop file and want to minimize the loss of image quality. We can add 1 or 2 points of Gaussian softening after zooming in, and then add 1 noise to ensure the zoom effect of the image. As for the proportion of enlargement and the degree of Gaussian softening, it is necessary to practice more. After Gaussian softening, be sure to check the sawtooth effect in the 2:1 field of view. Try to eliminate jaggies for best scanning results. Scanning dark originals for a number of reasons causes desktop scanners to not scan well-dark images. Its practical noise filter handles the dark areas of the image. Newton rings often appear when eliminating Newton's rings from scanning transmitted originals. Cleaning the scan roller and platform can reduce its production. But if it still exists, then use some simple methods: In part, use a duster equipped with corn flour, go to the place where you leave the scanner, squeeze the corn flour out of the duster, and let it scatter from the air. When the large particles of powder fall, hold the corner of the translucent paper and let it pass through the dusting area so that the fine particles in the air fall on it to achieve the purpose of eliminating the Newton ring. (This method I have never tried. The Newton ring scanning occurs due to the diffraction of light through the glass. The new scanner introduced by Microtek cancels the glass platform and uses a special light path design to eliminate Newton well. Ring.) When changing the image size, keep selected When we change the image size or the canvas size in Photoshop, the active selection will be lost. If you want to keep this selected outline, switch to Quick Mask mode before changing the size (press Q or select Quick Master mode in the toolbar). The image size command can change the image size together with the mask size. Changes in canvas size do not affect the size of the selection. (If you intend to increase the fabric size, first set the background color to black so that the new blank area is not selected.) When each command is completed, return to standard mode and restore the option outline. Maximize the gamut of the scanned image To make full use of a 30- or 36-bit scanner to increase the color range, use a scanner software (such as Agfa's FotoTune) or other company's software to adjust the color as much as possible because the Photoshop software is limited to 24 bits. The image, in contrast to our image, can be inserted with the widest gamut range. Combine images for better detail performance if the image to be scanned has a higher gradation range than our scanning ritual software can accommodate. For example, sky cloud skin tone with a lot of highlight details and dark shadows What should be done at the same time? The best way to do this is to scan the image twice with the requested scan resolution. One of the scanned images is adjusted to the largest bright detail, and the other image is adjusted to the largest dark detail. Open the image in Photoshop and open the layer selection dialog of the template, placing the two images in adjacent layers. This dialog box gives us the option of mixing each scan image (press Option to separate the sliders to make the midtones smoother.) If using the Live Picture software, insert the image into the adjacent layer, and Use the Insert brush to draw more detail on one layer than on the other. And such microwaves can be done in Photoshop using the brush and feather options. Live Picture software's resolution-independent brushes provide fast, natural hybrid images even at very high resolutions. Match the size of the newly created image to the one it opened. When we create a new image in Photoshop, the program automatically matches the resolution and size set on the clipboard, but we can also let the new image be generated. The size and resolution settings of the image match any open image. Open the New dialog and select any file name for the open file in the Window menu. Photoshop can capture the size and resolution of this image and reflect it in the corresponding new dialog box. Similarly, in the Image Size dialog box, we can change the size of an image to match another selected file name; or in the canvas dialog box, cut a file so that it is selected with another The files match. New Print Drive Output Management Tool The new Apogee Print Drive 2. l Open ConnectTM function that can input non-Agfa FBG processor data, enabling Apogee to connect non-Agfa workflows to McAfee output systems, including film output printers, plate makers, and proofers. In addition, Print Drive now supports multiple output devices. In addition, the Quick FixTM feature has been expanded to allow it to arrange or correct pages at the last minute. The more powerful grating processor Apogee Taipan TM 3.l raster processor has made great strides in speed, greatly improving the overall productivity. Second, by using Adobe's enhanced features, built-in trapping is faster. This feature is particularly helpful for direct-to-plate production environments because they need to handle large files often. Using a winning strategy Agfa's Apogee PDF production system has a wide user base and has won numerous awards, including the most recent 1999 GAFF Inter Tech Technology Award. Mr. Lin said: "When we started designing and developing Apogee, we had close cooperation with customers and partners. As a result, Apogee was widely accepted by the industry. We are also very happy that so many people all over the world have installed this system. In order to maintain Agfa’s leading position in open workflow solutions, we will continue to adopt a customer-led approach to development. We held two Apogee user conferences in November 1999 and February 2001 respectively. Tradition.
