Comparison between CORELDRAW and PHOTOSHOP format conversion

COREL DRAW and PHOTOSHOP have long been the famous design software on PCs. They are the first choice for professional design users. Both have their own advantages in graphics and image processing. COREL DRAW is the overlord of vector graphics processing, and PHOTOSHOP is a graphic image design. The best choice is to combine the two to give full play to your imagination and draw beautiful and magical patterns.

Obviously, this involves the question of how to correctly output graphics and images from COREL DRAW to PHOTOSHOP, which method is better.

There are many ways to generate dot-matrix images using COREL DRAW and PHOTOSHOP. The commonly used methods are: (1) Select the corresponding object in COREL DRAW, COPY, and then open a new file in PHOTO SHOP. PASTE goes up. The easiest method (hereinafter referred to as the “clipboard method”); (b) Using the COREL DRAW “output” function (some versions called “export”) in COREL DRAW, the COREL DRAW vector graphics are output as a bitmap ( Hereinafter referred to as "bitmap method").

In fact, there is a better way to use the output of COREL DRAW, output the graphics as EPS format, and use PLACE in Photoshop to achieve the conversion of vector to dot matrix (hereinafter referred to as "EPS" method. ). The following example describes this method in detail.

First, let us compare the advantages and disadvantages of these three methods. Figure 1 is generated using the “clipping method”. This method is characterized by its ease of use and no need to generate intermediate files. The disadvantage is that the image quality is poor. Because it is converted by the clipboard, the image is rough and there is no anti-aliasing (ANTI- The ALIAS effect is a method that is not advocated.

Figure 2 is generated by the "output method." The image generated by this method has a higher quality than the clipboard method. Therefore, many users use this method, but it has disadvantages compared to the EPS method.

Figure 3 is generated by the "EPS" method. The main advantage of this method is that after the output is EPS, the graphics are still vector graphics. RASTERIZE (rasterization) is only done in PHOTOSHOP, so the output process and the final image are resolved. Regardless of the rate, the quality of the final image depends on the resolution of the images you place in PHOTOSHOP. Once the "bitmap method" has been output, the resolution has been determined. If the image needs to be enlarged, there will be obvious sawtooth, and the "EPS method" will be of equal quality regardless of the image size.

The following specifically explains the operation of the "EPS" method:

First of all, complete your graph in COREL DRAW, select the corresponding part to be output, and then select “Export”, click “Select Only” option, format select “EPS”, set the file name, and confirm. Then start PHOTOSHOP, open a new file of appropriate size, select “PLACE” in “FILE” menu, select the EPS image just exported in COREL DRAW, and the image frame will appear in the new image file, you can pull the image. The box changes its size (press and hold SHIFT to constrain the length-width ratio), and finally double-click in the box, the graphic is placed in the PHOTO SHOP.

Use this method to pay attention to several issues:

1. The "Anti-alias Postscript" option in "PREFERENCE" in PHOTOSHOP should be selected;
2.EPS format is a common format in the professional printing industry, so its internal color is in CMYK format. In the process of outputting EPS, some colors that exceed the CMYK color space 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, it can be concluded that a simple and quick “clipboard method” or “bitmap method” can be used when the image requirement is not high; when the demand is high (such as when making a draft), Use "EPS method" to achieve higher image quality.
Finally, it needs to be pointed out that: COREL DRAW export PHOTOSHOP to vector images There is another format, namely AI format. EPS format can save the bitmap and vector object in the pattern, and many softwares accept the EPS format; but the AI ​​format does not support much software. The method of exporting the AI ​​format is basically the same as that of the EPS. Note that the version number of the AI ​​should be correctly selected, otherwise it cannot be correctly imported in PHOTOSHOP.
