Coreldraw to Photoshop format conversion method
Coreldraw and Photoshop have been well-known design software on PC for a long time, and are the first choice for professional design users. Both have their own advantages in graphics and image processing. Coreldraw is the overlord of vector graphics processing, while Photoshop is the best in flat image design. The choice, comprehensive application of the two can give full play to your imagination and draw beautiful and magical patterns.
Obviously, this involves how to correctly output the graphics and images in Coreldraw to Photoshop, and which method is better. There are many ways to generate bitmaps with Coreldraw and Photoshop. Generally, the commonly used methods are:
(1) Select the corresponding object in Coreldraw, COPY, and then open a new file in Photoshop, Paste up, this is the most convenient method (hereinafter referred to as the "clipboard method");
(2) Use Coreldraw's "output" function (some versions are called "export") in Coreldraw to output the vector graphics of Coreldraw as a bitmap (hereinafter referred to as "dotmap method").
In fact, there is a better way to use the output of Coreldraw to export graphics to EPS format, and then use placement (PLACE) in Photoshop to achieve the conversion of vector to dot matrix (hereinafter referred to as "EPS" method) . The method is described in detail below with examples.
First, let's compare the pros and cons of these three methods. It is generated by the "cut and paste method". This method is characterized by simplicity and ease of use, without the need to generate intermediate files. The disadvantage is that the image quality is poor. Because the clipboard is used for conversion, the image is rough and there is no anti-aliasing (ANTI-ALIAS) effect , Is a discouraged method.
The image generated by the "output method" has a higher quality than the clipboard method, so many users use this method, but it still has disadvantages compared to the "EPS" method.
The main advantage of the "EPS" method is that after the output is EPS, the graphics are still vector graphics, and the RASTERIZE (rasterization) is finally carried out in Photoshop, so the output process has nothing to do with the resolution of the final image. The quality depends on the resolution of the image files you put in Photoshop. Once the "dot pattern method" is output, the resolution is determined. If the image needs to be enlarged, there will be obvious aliasing, while the "EPS method" regardless of the size of the image, the quality is still as good. [next]
The following specifically describes the operation of the "EPS" method:
First, complete your graphic in Coreldraw, select the corresponding part to be output, then select "Output", click the "Only selected part" option, select "EPS" as the format, set the file name, and confirm. Then start Photoshop, open a new file of appropriate size, select "PLACE" in the "FILE" menu, select the EPS graphic output in Coreldraw just now, an image frame will appear in the new image file, you can pull the image frame Change its size (hold SHIFT to constrain the ratio of length to width), and finally double-click in the box, the graphic is placed into Photoshop.
Pay attention to several issues when using this method:
1. The option "Anti-alias PostScript" in "PREFERENCE" in Photoshop should be selected;
2. The EPS format is a common format for the professional printing industry, so its internal colors are in the CMYK format. During the output into EPS, some colors beyond the CMYK color gamut will be converted;
3. Some graphics that are too complex (such as containing too many gradient fills) are prone to errors during the conversion process.
To sum up, you can get the conclusion that when the image requirements are not high, you can use the simple and quick "clipboard method" or "dot matrix method"; in the occasions with higher requirements (such as when making prints), you can Use the "EPS method" to achieve higher image quality.
Finally, it should be pointed out that Coreldraw has another format for exporting vector graphics to Photoshop, namely the AI ​​format. The EPS format can save the bitmap and vector objects in the pattern, and many softwares accept the EPS format; but the AI ​​format supports not many software. The method of exporting the AI ​​format is basically the same as EPS. Note that the version number of the AI ​​should be selected correctly, otherwise it cannot be imported correctly in Photoshop.
