We are here not in the MS Excel forum.
But when you create a PDF with Save as Adobe PDF you have to select PDF/X-1a to get a CMYK file.
But be aware that Excel is only working in RGB and even if the output might be converted into a CMYK file, it will not mean that this file is print ready. Probably the black will consist of all four color plates.
Don’t use the virtual PDF printer. What for? From professional applications like InDesign, you can export a PDF, from MS Office you can save as Adobe PDF. Even if no Acrobat Pro is installed you can Save as PDF from any print dialog, even if this PDF is created with Apples Quartz technology.
Thank you Will for your answer.
I know that. And i ve already tried with (PDF/X1) but the problem still remains.
And also for the margin (without the pdf virtual printer) i cannot operate on them...
I need to create a CMYK file from excel that allows me to "isolate" the black.
When i open the file in Acrobat and i select the black (to make a test), some gray color stil remains under the words!
This is my problem.
That is, because it comes from MS Office. A virtual printer would not solve it.
In Acroabt PRO you can convert colored blacks to clean K-black.
