Sometimes, when a job will not plot correctly due to large file size, converting to PDF will reduce the size and result in a successful plot. A good way to create a PDF file from an application such as Powerpoint is to use the Adobe program Acrobat Pro.† If you don't have access to Acrobat Pro, you can find it in one of the public PC labs, such as Sage 4510 and the computers in the VCC Lobby that have the Sage 4510 image.
You will usually want to create the PDF file with the same large page size as in your application. (If you create a letter-size page and scale it up, the quality of the plot may suffer.) Preserving the large page size is often not easy to do from an application like Powerpoint, but the following 2-step method should work.
- Print to a file:
Use your application's Print menu to print to a file, choosing vcplt as the printer. Make sure to select the correct paper size and check the box for "Print to file". Name the file with a .ps extension, for example, "myplot.ps".
- Use Acrobat Pro to create a PDF file:
Open Acrobat Pro, choose File -> Create pdf -> from file
- Choose PostScript as the file type.
- Navigate to the folder where the .ps file is located.
- Click on "Settings.. at the bottom of the window. In the window that opens, at the right of Adobe PDF settings,
click on Edit and choose the appropriate page size (bottom of window) and 300dpi as the resolution.
- Also, if availiable, uncheck the boxes for Accessibility and Bookmarks.
- Select the .ps file you just created, and click on Open to create the PDF file. You may not get a chance to choose what folder the PDF goes in, but the PDF will open and you can do "Save as" to put it where you want.
You should now be able to use the Print menu from Acrobat Pro to send your file to one of the plotters. Be sure to select an appropriate paper size.
If the plot still does not succeed, perhaps it is still too large. You can try one of the following:
• In Acrobat Pro, go to File -> Reduce File Size... and select a later version of Acrobat.
• You could also try creating the PDF file at a lower resolution (see step 2 above).
†Note that GSView, which calls upon the ghostscript program, can also create PDF files from PostScript files. Usually, Acrobat Pro is better, but sometimes GSView succeeds where Acrobat fails.
If you have GSView, you can also use it to view your .ps file and see a more accurate preview of the plot than the one displayed by your application or the previewer in the Print window.
