As an excellent graphic design software, CorelDRAW graphic processing software has been widely used in prepress design. When using the PSP NT Century RIP printer to output the layout designed using CorelDRAW software, the output often fails to meet the requirements (such as: the output of the text is not true, the output of the text does not match the font used in the design, the image or The color of the text is wrong, etc.), and it is believed that the cause of the problem is not the output device (such as a laser imagesetter). Some of the problems that arise when the output does not meet the design requirements are mainly due to the use of CorelDRAW graphics software and output software. The operator's improper operation is its main source. This article uses CorelDRAW9.0 graphics processing software for layout design and the use of Founder PSPNT century RIP output software as an example, describes the common causes and processing methods of the output problems that do not meet the design requirements.

First, the reason for the false output text and the processing method
When outputting a CorelDRAW file, if the text portion of the file is not converted to a curve, the text portion of the file is rendered imaginary when it is output using the Founder PSPNT Century RIP, and thus the printed text is not real. The reason is that the saved CorelDRAW file is not a Postscript file that can be recognized by the Founder PSPNT century RIP, so when the RIP interprets the layout, the layout information cannot be completely recognized, and the text part of the output is rendered imaginary.
There are two ways to deal with this situation: The first one is to install an EPS plug-in in CorelDRAW graphics software, use the Founder PSPNT century RIP to output the EPS file; the other is to directly file the file in CorelDRAW graphics software The output is a PS file and the EPS file is output in RIP.
The method of installing an EPS plug-in in CorelDRAW graphic software is very simple. You can download the EPS plug-in in the CorelDRAW corresponding version on the Internet. For example, the EPS plug-in in CorelDRAW 9.0 is IEPEPS91.flt. The installation method is to copy the IEPEPS91.flt file to the Graphics9\Filters directory in the COREL installation directory and replace the original file. At this point, you can use the CorelDRAW graphics software to output the layout to an EPS file. The specific operation method is shown in Figure 1 and Figure 2. After getting the EPS file, you can use the Founder PSPNT century RIP to output the EPS file. The text part after the RIP explains the layout is very clear (as shown in Figure 3).
If you cannot find the EPS plug-in file temporarily, you can directly output the file as a PS file in CorelDRAW graphic software. This also makes the text after RIP interpretation very clear. Only when the output is a PS file, be sure to note that the layout size is the same as the designed layout size, and the effective output content in the layout must be included in the layout of the effective output layout. The specific operation method is shown in Figure 4 and Figure 5. After obtaining the PS file, the output of the PS file is also clear when using the PSPNT Century RIP.
Second, the reason that the output text does not match with the font used in the design and its processing method
When using the Founder PSPNT Century RIP to output layouts designed using CDR files, the output text does not match the fonts used in the design. It is also a very common problem. When the printed layout and the output are not in the same location or in the same unit, the output of other output files produced by other systems will often be incompatible or have other defects when the output is output to the CorelDRAW file due to system differences. The fact that the fonts do not match the fonts used in the design is due to the fonts used in the fonts used in the output. It should be said that this kind of situation can be avoided. Only after the text in the design layout is converted into a curve, normal output can be performed no matter what kind of output software is used. However, in the current situation where network transmission is very convenient, off-site output prefers to transfer the original layout file (CDR file) designed by CorelDRAW software to the output area through the network, and then process the CorelDRAW original layout file for output. The advantage of this is that in order to enable fast transfer of small files, we know that the output capacity of CorelDRAW files (mainly EPS or PS files) is very large, and such files are very slow when transmitted over the network. Yes, there may be lost file information during transmission, or even remote transmission at all. On the other hand, in order to make changes to errors in the layout at the time of output, CorelDRAW original layout files are also required for the transferred files. After receiving the CDR file transmitted from the remote network after being output, in order to output normally, the received file must be opened locally and converted into a file that can be output before the output operation can be performed. If the locally installed CorelDRAW software does not have all the fonts used in the layout, the system will prompt you if you need to use another font instead. If you choose to use another font instead, the original layout will be Some of the fonts will change, causing the output text to be inconsistent with the font used in the design.
The processing of the output text does not match the font used in the design is very simple, only need to install the missing font to the local computer system C:\WINNT\Fonts path (as shown in Figure 6).
Third, in the output of the image or text color deviation causes and processing methods
When outputting a CorelDRAW file, if there is a deviation between the color of the image or text and the color of the design, the main reason may be that in the layout design, multiple layers of images, graphics, or text overlays are used, two or More than one stack of different color levels will become another color. Although what is seen on the display screen at this time is the color desired by the designer, it is actually the effect of multiple colors superimposed upon output (as shown in FIGS. 7 and 8). It's like printing with unsmooth printing. After printing with multiple colors, it becomes other colors.
The reason for the above output and design deviation is mainly related to the parameter setting when the RIP output. When using the PSPNT century RIP file to output the file, the “graphical hollow parameter†option value in the “RIP parameter†option is selected “Not empty ". After selecting this option value, the superimposed color patches at the time of output are compatible, and therefore, the outputted color patches will deviate from the designed color patches. The processing method is to select “empty†in “RIP Parameters†option in “RIP Parameters†option in RIP software. The specific operation method is shown in Figure 9. After the RIP parameters are set correctly, the colors of the displayed color blocks in the RIP are exactly the same as the color blocks in the design (as shown in Figure 10).
The above introduces the causes of the several common problems in the output of CorelDRAW files in Founder RIP, and gives a brief introduction to the methods. The processing methods of these problems have certain reference value for the use of different design and output software. The causes of similar problems in some systems are basically the same, but they should be paid more attention in the output operation. As long as the operator carefully inspects the printed layout, it can quickly find and solve the problems encountered in the output.
