Identifying black and white versus greyscale in PDF

Is there a way to identify from within a scanned PDF document (ie, something like a document property) that it was scanned as greyscale, black and white, or color? My company is using Acrobat 7.0. We have a requirement, for a variety of reasons, that PDFs for certain projects be provided as black and white scans only, but all too frequently we get them in greyscale or color. We need to be able to easily identify that a PDF is not black and white.
Thanks in advance!

How to identify black and white images for dynamic collection ?

Hello
I would like to make a dynamic collection to quickly find my black & white pictures. It is very easy to do with your original files which have undergone a black and white (Grey) conversion under the developpement module : you have to specify "treatment - is - Grey level" in the dynamic collection description.
But what about original Grey levels images ? I have some scans of black and white negatives, and I would like to see them in the same collection.
I have tried to use EXIF metada, but none of them is related to this information (neither does IPTC). But such images are well detected as Grey levels images in the development module...
I don't know how to do (unless manually tagging images of course).
Does anybody have a clue for an automated solution ?
Thanks
Erwann

yes Eclipse 2.0 provides runtime chartting.
Please refer to this thread
[chartting|Re: Charts won't appear in CR Viewer?]
void AddChart(ReportClientDocument clientDoc, String chartTitle)
ChartDefinition chartDefinition = new ChartDefinition();
chartDefinition.setChartType(ChartType.group);
IDataDefinition dataDefinition = clientDoc.getDataDefController().getDataDefinition();
Fields conditionFields = new Fields();
IField field = dataDefinition.getGroups().getGroup(0).getConditionField();
conditionFields.addElement(field);
chartDefinition.setConditionFields(conditionFields);
Fields dataFields = new Fields();
for (int i = 0; i < dataDefinition.getSummaryFields().size(); i++)
IField summaryField = dataDefinition.getSummaryFields().getField(i);
dataFields.addElement(summaryField);
chartDefinition.setDataFields(dataFields);
ChartObject chartObject = new ChartObject();
chartObject.setChartDefinition(chartDefinition);
ChartStyleType chartStyleType = ChartStyleType.pie;
AreaSectionKind chartPlacement = AreaSectionKind.pageHeader;
chartObject.getChartStyle().setType(chartStyleType);
chartObject.setChartReportArea(chartPlacement);
chartObject.getChartStyle().getTextOptions().setTitle(chartTitle);
chartObject.setHeight(5000);
chartObject.setWidth(5000);
chartObject.setTop(1000);
IArea reportHeaderArea = reportDefController.getReportDefinition().getReportHeaderArea();
Section chartSection =(Section)reportHeaderArea.getSections().getSection(0);
clientDoc.getReportDefController().getReportObjectController().add(chartObject, chartSection, 1);
Further you can format the fields as per your requirement.
Hope this helps

Animated gif changes to black and white when exporting

A student created an animated gif of a solar system for class. When he tries to export it as an animated web gif, it changes everything to grayscale.

If you go to File>Image Preview, there's a drop down menu called "palette". This is probably set to black and white or greyscale. Change it to exact or adaptive.

How can I print in black and white?

I have asked friends how to print in black and white and they show me how to do it on their computers. They do it by just switching the colorysync profile to black and white or greyscale but when I go to print and go to the same drop down menu for colorsync profiles, there are no other profiles.

First, as print dialog box functions vary with the Mac OS version, we need to know what version of the Mac OS you have. "iOS 5.0.1" in your profile is not a computer OS but rather for iDevices. Do "About this Mac" from the Apple menu to see what version you really have. It should be 10.something
Second: control of the type of printing is int eh hands of the printer software, Please post the both the make and model of printer you are using.

Print black and white only, on Hp photosmart 5514.

Hi,
I dont like it at all that i have to contact support forums for something like this.
it use to be so easy to choose color or black and white printing.
Why have you made it so difficult ? Totally pisses me off but i leave that for the feedback section.
I have seen others with the same problem so it is not only me. now it has taken more than 20 minutes and i have to get to work soon.
So, how do I print black and white (or greyscale) using my newly bought hp photosmart 5514 ? ( is it smart ???)
I have been wasting a lot of ink now, very unsmooth not having it available in the ordinary printing window.
Like it matters, i use win 7 blablabla

I also hate that there is NO WHERE to find a simple answer. I have a "HUGE" XL cartridge of black only. Then I have to buy all the stupid little tiny color cartridges AND another little black cartridge.
Here I suppose: when I print in color, I use the color + small black cartridge.
When I want to print BLACK ONLY or GRAYSCALE, I choose that and it only prints using the XL big black cartridge.
WRONG. And no one can seem to answer this correctly, t but I know it does not work.
Remove 1 empty color cartridge whole printer won't work, even if I want black print only.
If all the small "color" cartridges + small blk cartridge is low but the BIG BLACK cartridge is showing full, still won't print BLACK ONLY.
I cannot PRINT with this stupid printer unless all cartridges have ink and are inserted. STUPID
I am now late to work simply because I cannot print a document PERIOD unless I have full color sitting there.
I just tried it multiple ways, grayscale, black only blah blah and it ALWAYS came out too- light, ie the sm blk cartridge was being used and it is admittedly LOW ON INK. WHAT is the big black cartridge doing there, saying it is full and not printing "black only" or "grayscale"?
The only article I could find that halfway enlioghtened me to the problem was HP page stating that "black" is never really black, to improve quality (thanks for making the decision for me) HP adds just a bit of color here and there to make black really black for paper quality paper.
SO SNARLING. Going to *bay to get refilled cartridges so I can print in a week. SNARL

Make iMac screen Black and White

LMAO!!! perfect haha!! thanks heaps matt. I saw the screen black/white to the left of the greyscale checkmark but totally didn't see that till you mentioned it LOL. Thanks!

Make Black and White PDF from Color JPGs

I don't have a scanner and use my digital camera to make 2-3 page document PDFs occasionally. I take a picture of a page, crop it in an image editor, and finally drag and drop the jpgs into Acrobat to create a pdf. The problem is that these docs don't print very well because they are created in color. Is there an easy way to make them in black and white instead of color? I don't want greyscale documents, because they don't print very well either.

Grayscale would be the way to go to retain shadows and tints.
I'm dealing with text-based documents on colored paper, so shadows and tints are exactly what I don't want.
Printing a greyscale image on a laser printer produces the same result as printing the original image in full color.
I'm not sure what you mean by that. Could you elaborate a bit?
I use a non-color laserjet. Printing a color document with a black and white printer and printing a greyscale document converted from that doc will print the exact same thing, i.e. black text with nasty grey backgrounds.

Converting a PDF to pure black and white

I'm currently attempting to convert a PDF of any colorspace (RGB, CMYK, Grayscale etc) to black and white.
Currently I'm walking the PDF using Adobe PDFLibrary, separating the contained PDEElements and identifying them (Image, text, etc).
Does anyone have any advice on how to proceed from here? I figure the actual conversion operation will have to be written from scratch, as Adobe doesn't seem to support this. However, I'm having a hard time determining the colors of each object. I suppose I could rasterize everything and convert pixel by pixel, but I'd like to avoid that and preserve vector images and such if at all possible.
Thanks in advance for any help!

Yes, I'm aware that there is no monochrome colorspace. However, wouldn't it be possible (likely at a very low level) to fetch and modify the colors of elements manually?
I suspect the initial thing to do is convert images to the DeviceGray colorspace and work from there, so I have a uniform colorspace to work with when performing this operation.
I've noticed that if I pull the ImageData object out of a PDEImage, I get an array of bytes that appear to be pixel by pixel color data. Now, in doing this have I rasterized the image? What would happen to vector images if this array were to be modified?

How to set default to convert a document to a black and white pdf file?

I have dozens of color Word files that I need to convert to black and white pdf files on a weekly cycle. I figured out that I can do this for individual files by clicking "print", "properties", then choose the "paper/quality" tab, and then click on "black and white". However, I cannot make the "black and white" selection permanent. That is, the next file requires me to go through the same four-step process to convert a Word file to a black and white pdf file. Any suggestions on how to make the "black and white" selection permenant?

Sorry. I forgot to mention that I am using Acrobat Adobe Pro 9.4.2.

How can I convert a pages color document to a PDF Black and White doc.

How can I convert a pages color document to a PDF Black and White doc. Or, covert the color to B&W in a new doc?

> How can I convert a pages color document to a PDF Black and White doc. Or, covert the color to B&W in a new doc?
The general idea is that you colour correct photographs once, archive, and convert with or without colour changes. The archived photograph is unchanged - or we would be colour correcting the same photographs again and again and again.
If you have a photograph with a corrected exposure, you can open the photograph in the Apple ColorSync Utility, apply a colour space conversion to a grayscale appearance using the preinstalled ICC profile, save the photograph under another name, and place that in your pagination.
If you have a paginated document with corrected exposures, and any such non-scalable bitmap or scalable spline graphics as you have chosen to add, you can render the pagination as a whole to PDF through the same ICC profile, carrying out the same colour space conversion on any and all objects.
Caveat: If you intend the pagination for certain processes, in particular offset lithography, then you are probably expected not to render the type to grayscale, but rather to render it to single ink solid black. No software can determine what printing process you intend, you have to understand a bit about printing, and how to set up general colour space conversions in software. Ask your prepress provider, and if the answer is not prompt and proficient, pick another provider.

Adobe 9 Black on White Document Scans to PDF Invert Black to White and vice versa! Not Good!

I have the same problem as TexasLawyer (Jul 30 2009) whose question was not answered nor was there any answer to a commenter who said he has the same problem ("I have an old HP LaserJet 3330 multifunction printer, and prefer scanning documents out of Adobe Acrobat rather than the software that came with the scanner. However, after upgrading to Acrobat 9 Professional, the scans result in negative images. I tried using the option in Acrobat to create negative images, hoping that that would result in a positive, but it didn't work. I'm using Windows XP, also.")
Me too. Except I am running XP as a virtual machine in a MAC (Snow Leopard). I "upgraded" to Acrobat 9 from a functioning Acrobat 6 (worked fine with my setup to make correct B&W pdf's from scanned B&W documents on the HP 3330 before I installed Adobe 9--I got updates immediately and am at version 9.1.3) butthe Acrobat 9.1.3 scans on the HP 3300 invert white to black and black to white. The printer option box to invert black and white images was unchecked. I checked it and ran the scan again but same result--white of paper document is black in pdf and black is white in pdf. I can scan the B on W document using grayscale and get B on W but the file is too large and unacceptable due to smudges picked up with gray scale.
Can't understand how so basic a use of Adobe is this messed up.This has to be a common problem since many many users scan black on white documents to pdf. Does anyone have a solution to this? It is critical in my profession.
Thanks in advance to you problem solvers out there that can solve this for me and hte others in my boat who search these forums looking for the answer to this issue.

I have an HP6010 scanner (sheet feed) that is used to scan multiple page documents. If I use the WIA scanner option I cannot select page size and the scanner defaults to legal size. On the other hand if I use the Twain driver I get negative images on my scans. I just installed Acrobat X Pro and the same thing is happening. I was using Acrobat 9. In fact in duplex mode the scanner outputs a negative image every other page, and a standard image on the alternate pages. Either way I am frustrated. I can't remember when the problem began, but I believe I was running XP SP2 and Acrobat 7 or 8.
Ironically, if I push the scan to PDF button on the scanner, which uses an HP utility, it comes out fine. All pages are in positive mode.
I did try scanning in color even though the document is black and white. I believe that the scan was fine. No negative images, but scanning in color is like watching the sun go down.
I thought it was Vista and System 7, then I was told that it had to be a scanner issue and that I needed to talk to HP. However, if the scanner functions properly on its own, with the HP utilities, then it has to be Acrobat.

Black and white pdf prints pink

I found an old black and white family photo online, downloaded and saved it as a pdf. But when I try to print it, it's is no longer black and white, but has a decided pinkish cast. This also happened with one letter from the same site. I have a mac flat panel, running OS 10.4.11, and an HP 5610 all in one printer. Is there any way to get this to print in B&W?
Also, when I tried to email the photo the way I've done previously -- go to print, then to pdf drop down menu and chose Mail PDF, I'm told its not supported. Same answer if I try Preview. I had to start an new email and add photo as an attachment. No biggie, but the way I had been doing it was easier.
Oh, and the last tine I used Adobe, I was alerted to an update, which I did install. Was this my first mistake?

Thanks. But just to be clear, the file as it sits on my desktop, is
black and white. The color, which reminds me of an photo that was
overexposed, only appears upon printing it. In fact, when I attach it
to an email, I again see the black and white photo. No color.
I will though try your suggestion.
Thanks,
Ken
