How to Create High Resolution TIFF Files From Excel Files

1. Create your file in Microsoft Excel. This can be anything from an invoice to a chart to a simple listing of data.
2. Select the area of your Excel spreadsheet that you want to convert to a TIFF file. Go to the 'Page Layout' menu then click 'Print Area' and 'Set Print Area' (this option may appear under 'File' menu in some older versions of Excel).
3. Print the file to a standard postscript printer (download a free file at Adobe.com). Name the postscript file and type in '.ps' without the quotation marks as the file extension.
4. Open the .ps file in Adobe Photoshop. A dialog box will open, asking you to confirm information about the file size and resolution. Type in the resolution you would like---300 pixels per inch and up is considered 'high-resolution' in most design applications. Set 'Mode' to CMYK. Click 'OK' to continue.
5. Look at the file in Photoshop to ensure that the output is the same as you saw in Excel. The text inside of an Excel chart may be different after the conversion---if you don't like it you can delete and re-add the text elements in Photoshop.
6. Adjust the size of the image in Photoshop if you'd like. You can crop it down, make it larger and even add photos and additional text as you see fit.
7. Go to 'File' then 'Save As' on the Photoshop menu. Select 'TIFF' from the 'Format' drop down list. Click 'Save' to create the TIFF file.
