Will inevitably arise in the work of a large number of images required standard and specifications, how to quickly deal with these pictures, but to picture the image is not distorted, and this requires a good image processing software. Here, I briefly explain how to use Photoshop cs3 batch processing images.
Images with Photoshop cs3 batch requires two steps.
1, action set. That is, you want to handle as any standard image style, set the pattern for the next batch.
1, open Photoshop cs3 interface, from the “Window” drop-down menu, select “Action”, create a new action, open the Record button to start recording.

2, from the need to address Choose a picture open, edit images, such as image size set to 1024 × 768 pixel, but also on the images according to their needs to set.

3, build a folder to save the processed images, you can built it on the computer first.

4 Export this picture, on a finished folder.

5, stop the recording action.
Second, batch picture.
1, from the “File” menu, find the “Auto”, select “batch.”

2, in the dialog box set: “Source Folder” to select the folder with pictures, “target folder” options built in to save the processed image folder.
3, the folder-owned projects are all checked.

4, “OK” to automatically handle pictures.
If you want to deal with different types of images saved after a different folder, to modify the “action” in the “Export” image destination folder.
Must do so according to the steps, or it will strike, and not “automatic” the.

Designed to do these people believe we have some understanding of the relationship between design and printing are inextricably linked, knowledge of printing to some extent is the design depth.

In a newspaper or magazine layout process, often encountered on the color image processing, a color when you open a picture, it might be RGB mode, it may be CMYK mode.So when using Photoshop is to use RGB mode or CMYK mode for color images using it?
Use Photoshop in the process of dealing with pictures, first of all it should be noted that, for the opening of an image, whether it is CMYK mode image, or RGB mode image, do not these two modes to switch between each other, not to two models will be spinning. Because the reign of image editing software, once for each image color space conversion, will lose some detail information of the original image. If a picture for a while turned into RGB mode, while conversion to CMYK mode, then the picture would be a big loss of information. It should be said that the newspaper publishing process for color printing plate picture pattern must be CMYK mode image, otherwise it will not be printed. But not to say that carrying out image processing mode when processing images to CMYK printing effect will certainly be good, or should be under the circumstances. In fact, dealing with the Photoshop image Select RGB mode stronger than the effect of the effect of using the CMYK mode, RGB mode as long as handle the image, then convert it into CMYK mode image after the output of film can be printed plate.

During image processing, if the open processing of the image itself is RGB mode image, or the original image input process using the scanner allows you to select RGB mode scanning, this newspaper’s layout for color is no better the. When scanning the original image using Photoshop as long as the menu bar select the File option in the RGB color settings set the option, through the input color image scanner shall RGB mode image. In short, without first transforming picture mode on the case, to get to the RGB mode the picture, you use this model to the image processing, especially the pictures downloaded from the Internet, to ensure that the picture of the printing effect, it must Use RGB mode processing. On the following aspects of exposition, clearly explains this view.

(1) RGB model is based on optical principle of all equipment used in color mode. Such as monitors, RGB mode based on the work. The RGB color model range is greater than CMYK mode, so, RGB mode to the performance of many colors, especially the vivid and bright colors (of course, the color display must be calibrated, and it does not appear picture color distortion).This color in printing is difficult to get out of India. This is the image color mode conversion from RGB to CMYK screen will dim when the main reason. RGB mode in Photoshop to edit the picture, you must first select the View menu in the CMYK Preview command (if using Photoshop for the Chinese version, then select the View menu bar of the Preview option, select one of the CMYK option to ), that is, using RGB mode editing pictures, and in CMYK mode display image, so the operator can see the color picture on the screen is actually needed for color printing, this is very important in the application at the time of printing this be a good image processing method. Photoshop work in CMYK mode, RGB color channel, one more than the other, it also use RGB CMYK simulated display of the display effect, and, CMYK of the calculations and based on completely different principles of optics RGB, therefore, CMYK mode of dealing with pictures of some less efficient to deal with image quality should be worse.

(2) the use of Photoshop image processing, some Photoshop filters in certain why he did not slow CMYK mode. In addition, the image editing often takes many subtle processes such as may want a few pictures of the contents of the portfolio together, as components of the original colors can not the same, they need to be adjusted, it may make the part of the synthesis in some way, and to filter and much more. No matter what image processing to achieve results, operators want to generate as much as possible and keep all kinds of subtle effects, as far as possible so that the screen has a real and rich detail, because the color range of RGB mode is much greater than the CMYK mode, and Therefore, RGB mode with pictures, in the editing process, will be a broader color space and a more subtle effect of changing the editor, and these effects, if used well, most can be maintained. Although ultimately have to convert CMYK color mode and will certainly be lost, but let the picture than the start color is lost or much better.

(3) in the RGB mode image into CMYK mode image, the color separation parameters of the effect will be good or bad image conversion played a decisive role. Adjustments to the color separation parameters, will greatly affect the image conversion, Photoshop image processing software with color separation parameters on the control. That is, when you need treatment will be a good picture RGB mode into CMYK mode output, the conversion process through the adjustment of color separation parameters can reduce the mode conversion in the picture the color is lost.

(4) present for the newspaper publishing, the images used in long-term retention need to keep image data in RGB mode is ideal. After color correction and amendment of the RGB mode image data can be an effective long-term storage of documents, so in the future to retrieve from the archives of the RGB mode image can be used in different output devices. For the RGB mode image data over many publishing process to be re-used, regardless of color separation method is used system-level color management method or the use of Photoshop’s image conversion method is very convenient.

(5) using a variety of printing, digital proofing devices, or calculators monitor for photo printing, proofing, output, the observation (and measurement) above the printed copy of the image output device color differences arise in the main method is to measure Ash needs of cyan, magenta and yellow content, printing copying system called gray balance. If the image is converted to CMYK mode, then re-use of different output devices, the image requires adjusting CMYK image of high light, the middle tones and shadow dot, and change the overall gray balance and color saturation. In order not to affect the image printing quality, the amount of black on the picture to be changed, but if not modified black print image data, it will produce undesirable printing results. For example, the original high-quality sheet-fed presses to the CMYK color separation mode image, if printed in the web press on the picture will make a large amount of black spots, its approach can only be modified CMYK mode image. The RGB model image available to a larger range of RGB color reproduction brighter, more saturated colors. However, as the CMYK color separation in the picture is, after all the pixels in the image are in the CMYK color range.

Can be seen by the above discussion, use Photoshop for color images should make use of RGB mode. However, during the operation should be noted: the use RGB mode image processing has to ensure that the model output with CMYK colors when the image authenticity; use the RGB mode of dealing with pictures make sure that picture has been fully processed and then converted to CMYK mode image, is best to leave a RGB mode image backup.
In addition to using RGB mode processing photographs, Photoshop’s Lab color mode is also good. RGB model is based on optical principles, and CMYK color model is color reflected light mode, Lab advantage of this pattern is that it makes up less than the first two color mode. RGB between the blue and green color too much over the green and red color too little over between, CMYK mode image in the process of editing the loss of color is more, in these aspects Lab mode the compensation. Lab model composed of three channels, L the channel that intensity, which controls the brightness and contrast, a channel, including the color from dark green (low brightness) to gray (in the brightness values) to bright pink (high brightness value) , b channels, including the color from light blue (low intensity value) to gray to yellow Focus (high brightness value). Lab mode and RGB mode similar to the color of the mixture will have a brighter color.Only the brightness channel of value changes only affect the color of light and shade. Lab mode can be seen as a two-channel RGB mode plus a luminance channel model. Lab mode is device-independent, this model can be edited with any of the pictures (including the gray-scale image), and RGB mode with the same fast, faster than the CMYK model is several times. Lab mode can guarantee that color mode conversion, CMYK color is not within the scope of the loss. If the RGB mode images into CMYK mode, the steps should add an intermediate step, that is first converted to Lab mode. In the non-color layout process, the application of Lab mode will convert the grayscale image is frequently used. For some the Internet to download the RGB mode the picture, if not converted to Lab mode before the transition gray level, then soar with the Founder or risperidone newspaper publishing software version row, sometimes not on the picture layout.

Thus, in editing pictures, use the Lab as the first mode or RGB mode, when converted to CMYK mode of last resort. Once transferred into CMYK mode picture, do not easily turn back, if indeed necessary, to turn into Lab mode of the image processing. If used to scan the input of the original picture is in color, but the picture is used for gray-scale layout, and use the scanner input image, do not directly input the original image to grayscale mode, RGB mode should enter the picture, with RGB mode handle the image, to convert the Lab mode before the picture, and then separated by the command channel, select the L-channel image as a grayscale image printing.

Most operators in the actual process of dealing with pictures, are relatively straightforward, and what kind of picture on the scanner, scan directly into the picture mode, and then after a little treatment for the layout, look also at the time of printing or such thing. In fact, if we really want to get good image printing quality, or do not bother, according to standard operating steps.
