Many plotting problems are due to huge files that overwhelm the capacity of the plotter. The size of the file in your application may not appear to be overly large, but this can be deceiving because files can expand greatly when converted to PostScript for printing.
- If you are using PowerPoint, check the page size to be sure no dimension is greater than 54 inches. See the PowerPoint instructions.
- If you are using Photoshop, check to be sure:
- your resolution is 300 pixels/inch or less. If your file is extremely large, you may have to select 150 pixels/inch.
- you have flattened the image layers if applicable.
- you have chosen JPEG as the output encoding.
See the Photoshop instructions for details.
- If your file is in PDF format, open the .pdf file with Acrobat Pro and use the File > Reduce File Size... option.
- If the overall resolution is 300 or less, the problem could be the resolution of imported images. Check that your images have resolutions of 300 or less. If not, recreating the images at lower resolutions may be the answer.
- Also, if your file contains imported graphics with different resolutions, the plotter will use a resolution that is a multiple of each of the component resolutions. The resulting resolution could be very large, greatly inflating the file size.
Changing the Format
If you cannot plot successfully from your original application using the above suggestions, try converting to another format. Usually the best choice is PDF. See the instructions for making PDF. If this does reduce the size sufficiently, use Acrobat Pro to reduce the file size (File > Reduce File Size...). Doing this can make the difference between a failed plot and a successful plot.
