Changing PDF logo colours

You won't be able to do any editing with Adobe Reader.

As mentioned above, Illustrator might be your best option, assuming you have any needed fonts, and the PDF and .eps were created from Illustrator*. If you want to use InDesign only, you can place the PDF or .eps into InDesign and export to a black & white PDF (see attached screen shot).

If you need a spot White color (check with your printer), place the new (BW) PDF into InDesign and add the spot White, then export to a new PDF (not BW).

*If you have missing fonts when you try to open the PDF or .eps in Illustrator, and you can't find them in Adobe Fonts, you can use Acrobat (not Reader) to convert the fonts in the PDF to outlines, then open the PDF in Illustrator.

Hi Paul,

what you can try with the PDF if it does not contain fonts:

Open the PDF with Acrobat Pro, go to: Edit PDF, select all parts of the logo you want to convert.

Then use the context menu and do:

Edit Using > Adobe Illustrator

When in Illustrator do Select All and use menu Convert To Grayscale .

Close the opened file and save, quit Illustrator and go back to Acrobat Pro.

This could work, but inspect the result carefully:

Acrobat's Print Production > Output Preview

If all is well save the PDF of the logo with a new name.

Regards,

Are you 100% absolutely positively sure that you cannot get hold of the original file? I don't mean "check your computer" ('yeah I did and I don't have an original'); I mean "call its designer" and/or "call your client".

Editing a PDF is ... something that the file format just was not designed for. The larger your change, the greater the chance something goes horribly wrong.

Editing the original file, however, should be a piece of cake. Even if you personally don't have the software, its original designer will have that and will be able to change color at a whim.
