If you have acrobat professional, you can use: Advanced > Print Production > Output Preview. Hover over the color, and the palette will display the CMYK values. However, this is is printing production tool, so even if your image or color block is RGB, the colors will displayed in the palette as CMYK.

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...!

How can I export to PDF for Offset printing including color and grayscale photo's?

After reading dozens of forum, I still don’t found the answer.
I made a photobook with full-colur and B/W photos for Offset printing. I want the B/W to be in grayscale to avoid color possible color shades. It seems InDesign doesn’t support grayscale, the images become way to dark. Even with exporting without any colour conversion or destination and/or including original colour profiles, the grayscale pictures are being exported to dark to PDF.

Yes, the Photoshop & ID CMYK working spaces are the same
This can get difficult because the 3 programs handle soft proofing differently.
The working spaces don't matter, it's the document profile(s) that manage the preview. So here is the same grayscale image placed in ID on top and PS on the bottom. I've set my Photoshop info to show the doc profile in the lower left corner. I can see my InDesign's Document CMYK profile in my Proof Setup (the Working CMYK is different and isn't being used). Both profiles are effectively the same Coated FOGRA39 (Black Ink FOGRA in the case of PS).
But the previews don't match because I have Overprint turned off, so the InDesign preview is Gamma 2.2 or a "screen" media preview.
If I turn on Overprint preview I get a match because I'm soft proofing for print:

How to detect color pages in a PDF?

I am using a C++ Acrobat plug-in do read/edit a PDF file.
I need to get the total number of pages in the PDF as well as the page numbers of color pages.
So far I have been able to get the total number of pages using PDDocGetNumPages() without any trouble.
However, I cant seem to find an API that lets me know whether a particular page is color or not. Is there a way to do this?
Thanks in advance!

But what if there is RGB data that means black or gray (R == G == B), does that mean black or RGB?
There is some sample code in the SDK for iterating over the content in the PDF, and then you can get the colorspace and the color of each object.
But you really need to do some background research on colors & colorspaces to properly achieve this goal.

How to scan both sides of document in color to pdf with the dr-m160?

how to scan both sides of document in color to pdf with the dr-m160?

Hi healthynhappy1.
To scan a 2-sided document, you will need to change the scanner settings in the software.
If you are using Capture On Touch:
You will need to turn off the "Scan in Full Auto" option.
Next, you will open [Scanner Settings] and change the "Scanning Side" to Duplex.
Verify that the [Color Mode] shows "24-bit Color" and when you get the option to save the file, verify the [File Type] shows as "PDF".
If you are using CapturePerfect:
Click [Scan].
Click [Scanner Settings].
Change the [Scan Side] to "Duplex".
Verify that [Color Mode] is set for "Color" and then save the file as "PDF".
I hope that this information is helpful to you. Should you need further assistance, please contact us at 1-800-OK-CANON (1-800-652-2666). Have a great day!

How to change highlight color of PDF texts to the standard golden yellow on Preview app?

I use the Preview app to read my PDF books. I also read these same books on my iPad. When I read my books, I like to highlight the text. I'm used to highlight my text with the standard golden yellow on my iPad. When I use Preview, the only choice of yellow color I've found is a somewhat orange yellow that's called "yellow". Besides that, I see only 5 highlight options. Anyway, I'd like to highlight my text on Preview with the standard golden yellow, the same color that is available in almost all PDF editing apps. Anyway, how can I highlight my pdf texts with the standard golden yellow on the Mac Preview app?!

Here is a picture to show the difference between the standard golden yellow (above) and the mac preview called yellow (below - looks like orange to me).
Is there a way to highlight the pdf texts on Preview app in the golden yellow color, shown above?

Is it possible, and if so, how do you color certain aspects of an inported PDF in InDesign?

Is it possible, and if so, how do you color certain aspects of an imported PDF in inDesign?

I appreciate it Steve! Yes, there is a television program, or use to be!
The one we had way back when, was a Chyron unit; and you could take a gray
scale drawing of a person from any source, including shooting a picture
with the studio camera, then color each item of clothing, on the person,
individually!
Thanks again!

How to transfer iBooks books & PDFs from old iPad to new iPad?

(Well, it seems my title got truncated; originally it read: How to transfer iBooks books & PDFs from old iPad to new iPad?)
I've recently gotten an iPad Air to replace my previous iPad 2. I have a bunch of books and PDFs in iBooks on the old iPad, and want to transfer them to the new iPad.
A search of Apple Support informs me that anything I've purchased from iBooks can be downloaded at any time to any of my devices (works like Amazon's Kindle system, apparently), but nearly all the content I have in iBooks on the iPad I've downloaded from other sources, so it won't be in my iBooks Store account (I might have bought one book there).
I've also seen several instructions on how to copy all my data from the old iPad to the new via Backup & Restore, but that seems to require restoring the new iPad to factory setup, which would delete everything I have on it now – including a bunch more books I've gotten since I started using the new iPad. And I don't want to copy everything, only the books/PDFs (the new iPad has everything I want, except for the books).
Since there seems to be no way to transfer files directly from one iPad to the other, it seems it must be done via iTunes on my MacBook Pro (and I want to copy all the books/PDFs to the computer anyway). So I connected the iPad 2 to my MacBook Pro (OS X 10.9.4) and opened iTunes (11.3.1). Then clicked on the iPad's name in the sidebar to the left, and on Books below it. I see a list of the books on the iPad. I check the little boxes by all their names to select them (not sure if that's necessary, but it seems like a good idea), then click on the Sync button at the lower right, to the right of the bar at the bottom of the window with colored bands showing memory usage on the iPad. A message appears saying "The app 'iBooks' was not installed on the iPad '[name]' because the app could not be found."
But iBooks is already on the iPad; I have it open and see the list of books in it, which matches the list shown in iTunes. The message has a "More Information" button; I click that and it opens an Apple Support article titled "iOS: An app you installed unexpectedly quits, stops responding, or won’t open": "Learn what to do if you see one of these issues with an app you downloaded from the App Store on your iPhone, iPad, or iPod touch: The app unexpectedly quits; The app stops responding; You can’t open the app." But none of these apply; the iBooks app is on the iPad, and works fine there.
The article suggests: (1) Restart the App. I've done that, no help. (2) Restart your device. Done that, no help. (3) Update your device software and your apps. The iPad is running iOS 6.1.3, iBooks 3.1.3; not the latest versions, no, but I'd rather not update it to newer, bigger, more power-hungry versions if I don't have to. Is it that iTunes 11 doesn't work with iOS 6? I haven't seen this stated anywhere.
So instead I click the OK button on the message, but nothing further happens, so far as I can tell: None of the books/PDFs on the iPad (about 380MB) appear in iBooks on the MacBook Pro.
I click on "Books" in the row of words across the top of the iTunes window, and it shows me the single PDF presently in iBooks on the MacBook Pro. I click the box by "Sync Books", and a message appears: "Are you sure you want to remove existing music, movies, TV shows, books, and tones from this iPad and sync with this iTunes library?" Well, no, that's exactly what I DON'T want to do. I don't want to erase the 380MB of books and PDFs on the iPad and replace them with the single PDF now in iBooks on the MacBook Pro. I want to copy the books from the iPad 2 to iTunes, so I can copy them back to the new iPad Air (if, God willing, I can figure out how to do that without erasing the books now on the iPad Air).
I've been working with Macintosh computers for over 26 years. It's always been a fairly simple process to copy files from one computer to another. I don't want to "sync" all the data (address book, email, God knows what else) on the iPad with the corresponding information on the MacBook Pro – especially if that will erase everything on the iPad (which has information not on the MacBook Pro, e.g. 380MB of books). I just want to copy the books and PDFs in iBooks from the old iPad to the MacBook Pro, then to the new iPad, adding them to the books on the new iPad, so I don't lose anything.
Can anybody give me a clue?

Transferring your prepaid cellular data account depends on your carrier. AT&T lets you move it yourself when you go to Cellular Data in Settings and log into your account with your previous AT&T user name and password. For iPads with Sprint service, you can set up an account on the new iPad and contact Sprint Customer Care (888-211-4727 and go through the menus) to deactivate the old plan and get credit for unused service. For Verizon, call the company’s customer service number for mobile broadband support (800-786-8419) and ask to have your account transferred.

How do I export a PDF in 100% black

I am currently trying to send an ad to a local newspaper, and apparently when I export my document it's not 100% black, instead it has mixed CMYK values. How can I export a PDF in InDesign so it preserves 100% black for the printers? All of the black text in my document has the color Black which is equal to C:0 M:0 Y:0 K:100 , what is the issue? Do I need to have specific export settings for a PDF?

Use the default PDF/X-1a preset.

How do I convert a pdf file to photoshop?

how do I convert a pdf file to photoshop?

unless you understand what you're doing and why, opening .pdf in Photoshop is a very risky move
because any vector objects, including fonts, will be pixelized (rastered at the chosen document ppi)
this really sucks if the designer delivered a professionally packaged PDF with vector elements because the vector will not print vector sharp
for example
a moron at a print shop drags PDF business cards or posters into Photoshop and prints pixelized vector objects -- when you ask why the vector didn't print sharp -- they are clueless
you also may hit profile issues that change the designer's color
there must be 50 ways to ruin a project (and 25 of them are downstream)...

Missing colors in pdf

When converting pdf from PM, i'm missing colors in the clip arts. Any idea? thank you

[email protected] wrote:
Sorry, I will explain my selft in more details. I'm using PM7 and my publication have 5 clip arts in colors. Those looks good. When I converted to PDF, the process is finished fine, except that the 4 of the 5 clip arts are missing the colors and shown in gray color. I wonder why just one of them is fine and the others failed the conversion. Please help if you have any idea. The clip arts was copied from free web site clip arts.
thank you
Andy
More details than that please. What file formats are these "cliparts", what color mode are they, are you placing them or pasting them? how are you "converting" to PDF, what PPD are you using?
Is there any difference in the 4 pieces of "clipart" turned gray and the one that didn't.

Multiply filter in illustrator with a 2 color job-pdf and print issues?

Hi,
Encountering a tricky problem and not sure if its an InDesign fix or an Illustrator fix.
I am working on a 2 color job—pms color + black on a book cover. The cover needs to seperate into these 2 colors.
Also, I need to make a high res and lowres pdf that look like the cover to send out to marketing, sales etc.
WHAT's THE PROBLEM?...
Well, I am creating a collage with black ink vector graphics on top of the pms background. I created this art in illustrator CS3. it is saved as an .eps file. The illos were done by someone who used a white fill to knock out black areas. There is also a wide 50% grey outline around the illustration.
I like the idea of the line of the illo being black and the fill being red so that it looks seethrough on the red background. But the 50% grey outline causes a problem...I'd like the 50% outline to blend with the red color, so instead of appearing like there is white in the ink it overprints.
The only way I could think of (and quickest way) was to apply the multiply filter in illustrator to the vector illo. This seemed to work great.
I brought the illo into InDesign CS3 where I created my cover layout.
Looks great, Prints great. Separations appear to be good, although it shows the yellow, cyan, and majenta layer they appear to be blank, so I think it will seperate nicely into 2 plates–PMS + black.
BUT, when I make a pdf, using "smallest file size" or using "high quality print", the pdf it makes does not show the illustrations in the collage. They are kind of beige and dulled out. The publisher needs pdfs too.
Does this at all indicate that this job will not print correctly using this multiply filter, or is it all well and good final product wise, but its just an issue making the pdf? I am slightly nervous I am going to send this off to the printer and they will have some issue.
I am a professional designer of 10 years with lots of print experience, but I have never used multiply in illustrator so I just want to make sure there is no rule against doing this I should know about. Does multiply at all mess with the color separations or is it fine? And how do I get my pdf to come out right? I'm hoping there's some dumb thing I'm forgetting, or a simple fix.
Thanks for any insight you may have!
L.

If you don't feel comfortable using Multiply you might want to communicate with the printer and ask if this is an issue for them to reproduce correctly. Some printers using older rips may have issues with transparency. If you can't speak directly with your printer you could mark up the file or make a PDF to accompany the working file with your comments about what prints at what percentage, and if it should overprint or knockout. Years ago I would get a file with transparency in it and have to make sure the designers intent was clear. This was in some cases due to the designer not understanding blend modes or what he/she wanted overprinting or knocking out in the printed piece. The other way you can confirm the separations are going to rip correctly is to print a PDF out of Indesign and open it in Acrobat pro. Under Advanced>Print Production>Output Preview you can turn on and off separations for the 2 spot colors in question. Because PDF acts as your rip in this case you should be seeing what separations your printer will be printing using your native Indesign file. Some print shops will require you to provide a PDF or a color laser print out for QA of your printed piece when sending files to prepress.
Hope this is helpful.

Colors in pdf files changed when I open those files in the iPad.

I usually use iPad and Goodreader for reading journal articles.
There is one big problem reading the papers using iPad because colors in pdf files looks abnormal.
When I use my labtop and desktop, I can see whole colors in the pdf files, so I can see what is exactly happening in the images in pdf files.
However, I cannot catch any details from those images in pdf files when I use my iPad.
For example, some colors in the pdf files disappeared and whole images in the pdf files looks too dark.
I searched for some informations to solve this problem using google but I cannot find exact method.
Many people said about this problem for a long time (maybe three years ago?) but it has not been solved yet.
Can anyone suggest me how to solve this problem?
If this issue cannot be solved, I think I do not have any reasons for using my iPad.

You've just uncovered something I don't really know. I had naively thought the Central Database and Cache are one and the same (and that the [ Purge Cache ] button would clear saved settings), but now I'm not so sure.
I tested by changing the parameters of a raw file, and I didn't see any files inside the Cache folder change their modification dates, which is not at all what I expected.
I don't really want to press the [ Purge Cache ] button to check it here, because I want to retain my own settings. You could try it and see if it clears the white balance setting on a particular file.
