How to Improve the Print Resolution of Excel Charts

File Prep
1. Finish drawing up your Microsoft Excel chart as you would normally.
2. Expand the size of the chart if necessary by grabbing a corner of the image with your mouse and dragging it outward.
3. Position the chart on the page exactly as you want it to look when it is printed. Confirm that the chart is positioned inside of the printable page by choosing 'Print Preview' from your menu.
Acrobat Method
4. Go to your Acrobat tab in Excel. Select 'Preferences' and then 'Advanced Settings' to check the resolution. If you are using Adobe's online PDF creation tool, called 'CreatePDF,' go to 'Set Options' and then 'Document Options' under your preferences. Select 'Print' as your desired profile. Click 'Edit Settings' and then 'Edit' once more to make changes to the resolution.
5. Assure that the resolution is set to at least 300 dpi (600 if you want a high-quality print).
6. Convert the file to PDF. Print your Excel chart from the PDF file to get a high-resolution print.
Photoshop Method
7. Install a postscript printer driver to your computer (see direct link in the Resources section).
8. Go to 'Print' on your Excel menu and find the postscript printer, which will likely be named 'General Postscript' or similar.
9. Click 'Properties' to the right of the printer name in your dialog box then 'Advanced.' Scroll down to 'Document Options' and click the plus sign beside 'PostScript Options.' Under 'PostScript Output Option' change the selection to 'Encapsulated PostScript (EPS).'
10. Press 'OK' to go back to the main print dialog box and select 'Print.' Save the file in a name that you will remember with the extension '.eps' at the end. (To find the file you may have to do a search of your computer files and folders.)
11. Open the EPS file in Adobe Photoshop. You will be prompted to enter the desired resolution before the file is opened. Set it to a minimum of 300 dpi and then open the file.
12. Save the file as either a PDF or TIF file in CMYK format (go to 'Image' and then 'Mode,' and choose 'CMYK Color' on the Photoshop menu). Print the Excel chart from Photoshop or another image-editing program.
