Convert 4-color pdf to greyscale

I have a four-color pdf that I need to convert to greyscale. The pdf now is CMYK set for Press Quality. What are the best settings for high quality greyscale output in Advanced - Print Production - Convert Colors. I am using Acrobat Professional 8.0. Thanks

As I said, I have not had much success that way either. Pro had the preflight conversion to Grayscale. Since you have Std, you may have to simply use separate graphic tools to convert to Grayscale and then recreate the PDF. If it is a scanned PDF, then you could simply save to a TIFF, use a graphic package to convert to grayscale (I use Irfanview for this type of simple task) and then move the TIFFs back into a PDF. If you have a mix of graphics and text, you may have to deal with a bit more. If the print converts the text, but not the graphics, you might try extracting the graphics (bitmaps I hope) under the tools menu. Convert those graphics to grayscale and then replace the color images with the new ones. (work on a copy of your PDF just in case something does not work)

Cannot convert Powerpoint to PDF in greyscale because there is no adobe option on the printing dropdown screen

How can I convert Powerpoint to PDF in greyscale - there is no adobe option on the printing dropdown screen?

Creating PDF from PowerPoint by printing to AdobePDF produces lousy PDF. All transparency is lost. Use the “Save as Adobe PDF” feature installed by Acrobat as a plug-in into Microsoft Office applications.
Once you have the PDF file created, within Acrobat you can use the Convert Colors tool under Print Production to convert to grayscale.

How convert a color PDF File to black & white (gray scale...no color)

How convert a color PDF File to black & white (gray scale...no color)??? creative cloud cs6... Acrobat etc

Hi, just wanted to add my 2¢
I've been in publishing over 25 years and live in Acrobat for making my final files. Currently with a newspaper.
This is what we do:
• Tool Panes > Print Production Window
• Select CONVERT COLORS
• Midway down under OUTPUT INTENT, check Convert Colors to Output Intent
• In the associated drop down menu, I choose (because I'm printing on newsprint) DOT GAIN 20% – If you're working on better stock, choose a lower dot gain percentage.
• Click OK – this will convert the file
• Save
Note: this affects the file you're working with. Make sure that you use this method on a COPY if you want to retain the original color version.
I think if you compare my method to the Preflight method, you'll see a tighter contrast and better blacks. I've always felt the Preflight method left continuous tones a little muddy.
Now if there was only a way to add that to ACTIONS...!

Preserving Black color values when converting color PDF to grayscale

I opened a full colored PDF document (exported from InDesign using Profile: Euroscale Coated v2) in Photoshop and tried to convert it to grayscale (image > mode > grayscale) and noticed that the black color values changed. text for example that was 100% black in the PDF document became a screen of 91% black.
is there a way to preserve color values when converting full color PDF documents to grayscale?
or in other words WHICH is the correct way to convert full color PDF documents or full color InDesign files to grayscale?
I am using Adobe CS 3, Acrobat 8 Professional, on Mac OS 10.5.5

Before you open the PDF in Photoshop, set PS's Color Settings to Photoshop 5 Default Spaces. When you open the PDF set the Mode to Grayscale in the Import dialog. Just remember to reset your color settings when you're done.
Edit: Also, if you want to match black percentages as well as 100% black, set the Photoshop Color Settings to Photoshop 5 Default Spaces with the Gray working space to Dot Gain 20%.

Convert color PDF to Black in Acrobat 9

I have need that I have not been able to find an answer to. I have a fairly large color pdf (over 400 pages of drawings in color) and I would like to turn all the colors to black. Everything I have been able find in my research to do this has to do with converting a color PDF to black & white (grayscale), I do not want to use grayscale, I need the colors to be converted to black. Any color other than white I want to be black. I realize that you can print to black and white but that will not work for me because there are a couple of pages in the PDF that are color models that I will reinsert back in to the PDF after I have converted the PDF.
If anyone can help in this endeavor it would be greatly appreciated.

For Acrobat 9 Pro it is:
File > Export > PDF/A

Converting AutoCAD to PDF (in monochrome)

Objective: to convert multiple AutoCAD files (via Windows Explorer) to PDF - converting from color to monochrome.
Now......I can successfully print to pdf from within AutoCAD and get monochrome outcome by selecting appropriate plotter configuration.
My problem is stemming from attempting for this same outcome by selecting multiple files within Windows Explorer, right clicking, and selecting "Convert to..." options.
1. I always get the color version
2. PDF plots tend to have additional white space/margins (not printing to page size).
- I've played with default settings in the print driver itself.
- I've been in Distiller and attempted some customized settings there.
I just can't seem to find where/how to get a positive outcome on this one.
Since my job entails me to do this routine quite often I would greatly appreciate any assistance I can get from you "pro's" out there.
Cuz' this "one at a time" routine in AutoCAD is wayyyy too time consuming.
With great appreciation!
Tracy
I should also include the facts that I am using: AutoCAD 2011, and Adobe Acrobate 9 Pro.

I am also having trouble with converting AutoCAD DWG to Adobe PDF. I have tried several different methods. I've tried outputing the color PDF to a post script file, however that is still in color. I've tried using custom Color Plot Styles (monochrome.ctb) and Named Plot Styles (monochrome.stb), but since I did not create the original AutoCAD DWG (it is 10 years old from 2004), they are not the correct plot style files. I do not have AutoCAD and use ProE/Creo instead. I've tried importing into my CAD tool, however all the fonts are different. I've also tried exporting the PDF to a raster format like TIFF but the resolution is really bad for engineering drawings. If I increase the resolution, then it sometimes will say that the image is too big and in cannot save/export the image.
It seems like this should be really simple to do in Adobe. I have Adobe Acrobat Pro 10. I can go to Tools > Print Production > Preflight > PDF Fixups > Convert to grayscale, which will convert to grayscale, but not to monochrome. Similarly I can go to Tools > Print Production > Convert Colors and select Conversion Profile to Gray Gamma 2.2, however that still will produce grayscale, but not monochrome.

Covert color pdf to a black & white

Does anyone know how to convert a color pdf into black and white? We're having some space issues on our server and have some documents that were scanned in color that we would like to convert to black and white to reduce the file size. I am using Adobe 8 Standard. I've tried printing the document to the Acrobat Distiller and choosing black and white in the print options, but it still prints it in color.

Have you done a search of the forum? There have been a few topics on this in the last few weeks.
There are options in PDF Optimize that some have tried to use and there is also an option under TOOLS>Print Production that has some options along this manner.
I have found that the conversion to B&W does not always seem to work as you have found. These other options might help. Bill

Converting cmyk PDF to greyscale. Lines are being altered!!

I have a big catalog, done in InDesign as a CMYK doc...exported to a Press Quality PDF. Printing it in black only, so I need to convert the doc to greyscale. I've googled for days, tried everything. It converts the doc to greyscale, but it's screwing around with the line weights of any lines I have on the page.   I have a 10 point horizontal line at the top and bottom, and the converted greyscale now has a 1 point line! Or I have an Illustrator logo with a 10 point white line around the logo, and the converted document has it down to a .5pt line! It's insane. Everything else seems to be okay. Some of the logos, which are actually already greyscale/black logos, disappear mostly, leaving just a few elements on the page. It's nuts. Last year, I did this exact same thing to the exact same files, and it worked 100% fine. Now, with new versions of ID, Acrobat, it's completely broken.
I'm at wits end. It's 508 pages, and I can not fathom how long it will take me to manually convert the thousands of photos in this thing to greyscale manually. It has to go to press.
I tried converting the master PDF using the Mac Preview app, via the Export > Quartz Filter > Greyscale.   It worked correctly, except the prepress guy says all the black text is now 4-C text, so it's useless.
I've tried using Convert Colors under Tools, I tried going through Prepress tools and doing it there, and it's always the same.
Any thoughts here?

I exported as a gamma 2.0 directly out of InDesign, and the lines stayed intact.   I didn't know you could export as a gs, I was told that you had to export a color pdf, then use PDF tools to convert the colors...but if you mess with the Output settings in Indesign PDF export dialog box, you can get to the gamma 1.8, 2.2, or dotgain greyscale presets, and the PDF came out perfect.

Convert Color PDF to Grayscale using Preflight in Acrobat 9 Pro

Has anyone posted a step-by-step procedure to convert color PDFs to grayscale? I've unsuccessfully been trying to use the new Preflight dialog to do this. This is the procedure I tried:
1) In the Preflight dialog, Create New Preflight Fixup.
2) Fixup Category: Color Spaces, Spot Colors, Inks. For Type of Fixup: Convert Colors.
3) In the Conversion settings tab, chose All Objects, Using Any Color (except spot colors), plus All Objects, Using Spot colors(s).
4) For Destination, I chose a grayscale destination Dot Gain 25%.
5) After clicking OK, I selected the new profile and clicked on the Fix button, and saved the file.
Nothing happens, and the colors don't change.
If anyone can explain what I'm missing, I would greatly appreciate it.

'Convert CMYK Colors to RGB' still runs havoc in 9! (Plus a PDF version problem)

This post is to warn people about severe issues, and how to avoid them. Issues with the CMYK color setting in FM9.x have been reported here earlier, such as:
http://forums.adobe.com/message/1237696#1237696
http://forums.adobe.com/message/1237852#1237852
http://forums.adobe.com/message/1237165#1237165
However, I do not think this issue has been warned about anywhere near as much as it should have. And, as usual, Adobe is silent (they should have a big poster on their site warning about this issue! And they have even claimed that patches have "solved" the issues with CMYK).
Just recently, while experimenting with FM9 again, I had extreme problems, which, at first, seemed totally unrelated to this CMYK setting. But after having struggled extremely hard for many many many hours, I finally found out. Now is the time to inform others:
First a note about versions: FrameMaker 9.0p237, Acrobat Distiller 9.1, XP SP2
It looks perfectly okay on screen in FrameMaker, exactly as in FM8. But when saved as pdf, several things are "corrupted". Examples: no kerning after the letter 'T', such as the word 'Text'. Dotted leader for a right aligned tab disappears. Some objects from the master pages, such as a logo, become enclosed in a rectangle (a border of the frame/object), but it only happens on *some* body pages, whereas other body pages using the same master page are ok!!? Equations are formatted differently from the way they should, with the wrong font for number, etcetera.
Solutions:
1. When 'Save as PDF...', untick 'Convert CMYK Colors to RGB' in PDF Setup. Same setting is in the file's 'Format > Document > PDF Setup...'
A drawback with this method is that, as of Acrobat Distiller v9, it does not seem to respect the pdf version specified in the PDF job Options! I get PDF 1.6 with this method, despite my job option specifies version 1.5. (This happens also with FrameMaker 8 if Acrobat is v9.) So you *have* to optimize it in Acrobat in order to get a web friendly PDF (PDF 1.4 or 1.5).
or
2. Print to 'Adobe PDF'.
In this latter case, you can set the same 'PDF Setup' settings under the button 'Setup...', EXCEPT that there is no tick box for 'Convert CMYK Colors to RGB', and it does not matter what setting you have chosen in the file's 'Format > Document > PDF Setup...', it will be RGB conversion in any case. Make sure that after you exit the setting, the tick box for 'Print to File' is NOT ticked! This method respects the pdf version specified in the PDF job Options! I get PDF 1.5, which is what my job option specifies.
(For some reason, Acrobat/Reader does not render these two PDFs exactly the same, except in extreme magnification! Maybe it has to do with the different PDF versions of the files.)
In either case, the solution actually solves ALL problems I listed! Despite it seems to have absolutely nothing whatsoever to do with colors! Some day in the distant future, CMYK might actually work! But, for myself, I would prefer a proper color management instead...
Best Regards,
/Harald

Oops!! Not until now I discover that under 'Solutions' I happened to write 'untick' where it should be 'tick'! I.e, colors SHOULD be converted to RGB in order to circumvent the problems! I.e it runs havoc in v9 when CMYK colors are NOT converted to RGB! Don't know how I came to write the opposite, but probably I started out by describing the situation where the problems are seen rather than describing how to avoid them.
Equally strange is that nobody corrected me, but perhaps the mistake was so obvious? (But whether you see problems or not might depend on what fonts you use. So, under certain special circumstances, CMYK might actually work without these reported problems.)
I am also a bit surprised that others haven't reported the issue that the PDF version set in PDF job Options isn't respected when using 'Save As PDF' and Acrobat 9? (Or maybe someone has, but I have missed it.)

Png within my document when converted to a pdf are printing black and white rest is color-help! WHY?

I am creating a document in Publisher & converting to a pdf. Most of my png elements within the document, are then printing black and white from the pdf (everything else is in color)? Don't know what is going on, doesn't seem to happen on all printers, is there a setting I am missing? Help! Thanks

Could be a setting in the PNGs when they are saved.
Have you tried saving them as GIFs and replacing them in the document(s)?

Turn colored pdf text to monochrome pdf

I want to print a pdf which contains coloured text to a b/w printer. Text now becomes unreadable greyscale. Is there a way to convert every text color in a pdf (or postscript) file to pure black? So not greyscale like in Acrobat, but 100% black? I'm working on a mac so there isn't a 'print as black' option in acrobat. Don't mind about the images, as long as the colored text is converted.

You can't print color to a Black and White Printer. All it has is Black ink or Black Toner. Either the image will be Shades of gray by controlling the amount and the distance of the drops of ink or bits of toner.
A Color Printer has 4 colors at minimum. Black, Red, Green, Blue; be it ink, or toner. These mixed according to the information sent to driver determines the color viewed.
So a Color PDF printed to a Black and White Printer is either Black and white or Shades of gray to make up the images.

Converting 4-Color Blacks to 100% Black

Is there a way to convert 4-Color Blacks(Rich Blacks) to 100% Black? For example today I got a file that was CMYK 4 Color however the blacks in the PDF file were not 100% Black is there a way to convert the 4 Color Blacks to 100% black in Acrobat? I don't want the whole PDF to be Greyscale. I still want the color but I want to specifically target the 4 color blacks and turn them to 100% black. Can this be done? I am using Acrobat 8.

It's possible but not easy.
You first need to identify exactly what the "rich black" in the document is - 4-plate CMYK, RGB, etc. then create a Preflight Check that finds only that color combination, with a second item in the check to filter only by text objects.
You can then use it as the trigger item for a Convert Colors preflight fixup, applying something like a dot gain 30, which will blow the rich black out to 100K.
