Transparency and color blend space: fail!

Hi there. I keep trying to export my pdf, to no avail.
I get an error that pops up that says there is an error with my transparency and color blend space.
HOWEVER, all my images are set to CMYK (it says so in the links panel) and my transparency blend space is also set to CMYK. I have no errors in my preflight panel. When I ignore the message and continue to export, the image looks completely different and not the way I want it to show up.
Please let me know how I can fix this error! Thanks so much!

Document CMYK is the assigned profile in Edit>Assign Profiles.... Working CMYK is Color Settings...>Working Spaces>CMYK. If there's no profile assigned, document and working are the same. So in this case Document CMYK is Coated FOGRA27 and Working CMYK is US Web Coated SWOP—the assigned FOGRA is color managing the document's native CMYK colors not the working US SWOP

Problem with adjusting both transparency and color of an object

I am writing a program where when an object is picked, both it's transparency and color will be altered (the object will become opaque, and its color will turn to a predefined "selected" color), while the previously selected object will return to its original transparency and color. I am able to get this to work, except that objects that were picked two or more picks ago will remain in the selected color, albeit in their original transparency. This problem only seems to occur when transparency is factored in. The picking/color & transparency altering code is as follows.
public class PickingListener extends MouseAdapter {
     private PickCanvas pickCanvas;
     private TextDisplay overlay;
     private Primitive p;
     private Primitive lastP;
     private ColoringAttributes origColor;
     private TransparencyAttributes origTransparency;
     public PickingListener(PickCanvas pickCanvasArg, TextDisplay overlayArg) {
          pickCanvas = pickCanvasArg;
          overlay = overlayArg;
     public void mouseClicked(MouseEvent e) {
          pickCanvas.setShapeLocation(e);
          PickResult result = pickCanvas.pickClosest();
          if (result == null) {
               System.out.println("Nothing picked");
          } else {
               p = (Primitive) result.getNode(PickResult.PRIMITIVE);
               if (p != null) {
                    setSelectedColor();
                    overlay.setPickedBarInfo((BarInformation) p.getUserData());
               else
                    System.out.println("null");
     private void setSelectedColor() {
          ColoringAttributes barCA = new ColoringAttributes();
          TransparencyAttributes barTransp = new TransparencyAttributes(TransparencyAttributes.NICEST, 0.0f);
          barCA.setColor(ColorConstants.SELECTED);
          if (lastP != null) {
               lastP.getAppearance().setColoringAttributes(origColor);
               lastP.getAppearance().setTransparencyAttributes(origTransparency);
          origColor = p.getAppearance().getColoringAttributes();
          origTransparency = p.getAppearance().getTransparencyAttributes();
          p.getAppearance().setColoringAttributes(barCA);
          p.getAppearance().setTransparencyAttributes(barTransp);
          lastP = p;
}Capabilities to alter the primitive's color and transparency are all set.
     barAppearance.setCapability(Appearance.ALLOW_COLORING_ATTRIBUTES_READ);
          barAppearance.setCapability(Appearance.ALLOW_COLORING_ATTRIBUTES_WRITE);
          barAppearance.setCapability(Appearance.ALLOW_TRANSPARENCY_ATTRIBUTES_WRITE);          barAppearance.setCapability(Appearance.ALLOW_TRANSPARENCY_ATTRIBUTES_READ);
ColoringAttributes barCA = new ColoringAttributes();
barCA.setCapability(ColoringAttributes.ALLOW_COLOR_WRITE);
barCA.setCapability(ColoringAttributes.ALLOW_COLOR_READ);)
Any insight as to why this would occur would be greatly appreciated.

A Behavior is the preferred way to make changes in a scenegraph. Here is an example from a previous post that changes the appearance of a shape when it collides with another shape.
The javadoc for javax.media.j3d.Behavior appears to refer to the issue you have.
Transparencies are confusing, different display adapters deal with them differently. Suggest you search the forum at

RGB and CMYK blend spaces for document creation

If I create a new document with the print profile it sets the blend space to CMYK. Will I be seeing a true representation of the colours or do I need to switch to an RGB blend spaces while creating the document then switch to CMYK when I'm ready to print?

I'm wanting to know what to set the colours to while I'm working on the document to make sure the colours I choose are going to be the same as what I print. I'd use RGB while creating a document onscreen then change to CMKY when I'm printing to maintain a true representation of colours. Can I do the same thing using the transparency blend space?

Need help with transparency and color quality in the forground

I need to make an image that is comprised of a collage in the back with a clear visible logo on top. I'm not sure if I'll need to change the hue's of the background collage images to create the image or if theres a way to make the image somewhat see through but keep true to the colors of the forground?

I agree with Trevor. I think you are over thinking the issue. Just place a logo in the same document, scale it, adjust its opacity if necessary and your done. As for the background of the logo, that can depend on how it was created. Preferable in photoshop so that you have a transparent background. But if the background happens to be pure white or black, you can use blend modes to remove the background.
But I am getting ahead of my self. Lets see how you do, post your results, if necessary a screen capture of photoshop with the layers panel open.

FileFormat: Reading transparency and color data separatley

I have a problem reading data via my file format plugin.
I can read the different layers in the format in Lab color mode (8-Bit).
In the file there is a layer transparency mask (1 byte for every pixel), which is stored right before the image data.
Currently I tried 2 approaches:
1.
- Set transparencyPlane to 3
- Set loPlane, hiPlane to 3
- Set colBytes to 1
- Set rowBytes to image width
- Set data to a buffer with size of image width
- read row from the transparency mask
-> advanceState gives error (-30500)
2.
- read transparency mask completely (I know, bad idea)
- Set transparencyPlane to 3
- Set loPlane = 0, hiPlane = 3
- Set colBytes to 4
- Set rowBytes to image width * 4
- Set data to a buffer with size of image width * 4
- read row from file in a temp. buffer
- copy values from temp. buffer and transparency for every pixel to the data buffer
-> advanceState ok but image ks not correct in PS
I think there must be another, better way to apply this transparency mask.
Thank you for your help....

Problem solved.
I forgot to tell PS the correct count of planes in the readStart selector.
So approach 1 was right.

PDF Background Transparency and Color

I have several PDF pages that are vector black line-drawings that have been placed into a document as a gallery, which works great.
However, when you click on the PDF to view it in isolation, the background turns black and the drawing is hardly visable.
I am able to convert the PDF's to a raster format, but would like to know if there is a way to change the background color when viewing an image in isolation.
Thank you in advance,

I just realized that converting the PDF's to a raster format is not a preferable option, as the sepia background of the picture frame fill is preferred.
Can the background of the image isolation mode be changed (to match the sepia background of the picture frame fill)?

Transparency and color falloff with depth effect?

Videocopilot's 3D Falloff effect isn't compatible beyond CS4. How would I create this effect in CS5 or above?
http://www.videocopilot.net/tutorials/3d_falloff/

It's an easy expression involving distance calculation with length(point A, point B) and then feeding the result into a linear() on whatever property you need it, in this case obviously camera distance tied to a DOF filter or whatever... So in this case it would look like
camPos=thisComp.layeer("Camera").transform.position;
layPos=thisComp.layeer("XYZ").transform.position;
camDist=length(camPos,layPos);
linear(camDist(minDist,maxDist,minBlur,maxBlur)
Just fill in values for the min/max stuff...

Indesign quit unexpectedly with this error " Transparency blend Space "

i need some hand-helping please
I just exported to pdf, and got this message, and would be happy to fix it if I had a clue what to do:
The document's transparency blend space doesn't match the destination color space specified in the Export Adobe PDF settings. To avoid color appearance changes in the PDF, click cancel and change either the document's transparency blend space, or the destination color space.
i’ve checked the Edit.Transparency Blend Space which is already on CMYK i have no PDF's placed in the document. also checked Adobe PDF Presets; "Output" tab; Change "Destination" to Document CMYK - U.S. Web Coated. which works for me.
but no matter which preset i pick ; as soon as indesign starts to make a PDF file InDesign has unexpectedly quit.
i though it might be fix with uninstall and reinstall .. done but the problem is still there i also try another file which i worked on before and they had no problem but the result are the same for them as well . I'm getting the same message I started with.
using cc version will be appreciate if any one could point me what is the problem and what to do ?

This probably has nothing to do with transparency or the blend space -- that's a common non-fatal error that crops up when you are using a color profile that doesn't match the one specified in the preset.
Start by trashing the prefs. See Replace Your Preferences
If that doesn't solve it, see Adobe Community: File Crashing on Output - printing/PDF/other

Document's transparency blend space? Destination color space?

I need some hand-holding please.
I just exported to pdf, and got this message, and would be happy to fix it if I had a clue what to do:
The document's transparency blend space doesn't match the destination color space specified in the Export Adobe PDF settings.
To avoid color appearance changes in the PDF, click cancel and change either the document's transparency blend space, or the destination color space.
Can you please translate that into English and tell me what to do?

OK, I've reproduced the problem, and here's what I'd do.
You've placed RGB images over CMYK vector paterns made in Illustrator, which in some ways makes things more complex than if the imges and backgrounds were all in a single color space, but it looks as if only the backgrounds are going to be affected by any flattening that will be taking place in the conversion, so if there is any color shifting due to the flattening and choice of space, and I don't see any, it will be isolated to the background texture and probably not noticeable.
Since you have two destinations, you need two differnt PDFs. The sample is very interesting, but I suspect the print run will be small -- limited to family members -- so the first thing to do is ask the printer what PDF export settings he wants you to use. If you're going to have this printed somewhere like Kinkos or Staples, they probably can't answer that question, and I'd stick with the High Quality Print preset, and be sure the compatibility is set to Acrobat 5 or higher so the transparency isn't flattened. Print one page as a sample before committing to the entire job to check the color (and don't expect miracles from the average copy shop running a color copier -- they usually just aren't set up to handle color management and matching).
For the screen version, set the blend space to RGB and choose the Smallest File Size preset. you shouldn't get the warning (but you could ignore it even if you did). If the file is still too big, set the compressin settings to downsample color and grayscale to 75 ppi and lineart to 600 and see if that helps before you try reducing the quality in the compression. The prints off a desktop printer won't be quite as good as they will be at 100ppi, but probably acceptable on most inexpensive paper stocks that peopl seem to use, and hopefully they are going to get the better printed version, anyway.

Changing transparency blend space

I have a bunch of InDesign files that were created for print that I now need to save with RGB colors at the behest of my ePub developer. I have a simple script to change my pantone spot swatches to RGB, but I want to add a line to that to change the documents' transparency blend space to RGB. Right now they're all using a CMYK blend space. I'm a scripting novice, obviously. Does anyone have a relevant example or suggestion? Thanks in advance.

@mcanespy – it's a preference:
app.documents[0].transparencyPreferences.blendingSpace = BlendingSpace.RGB;

Color blender tool and other questions

Hey. I've got Photoshop CS4, which I've been using pretty successfully for digital and pixel art, but there's still a lot to the program that's unknown to me, and trying to google up an answer isn't getting me anywhere. I've got a few questions.
Is there some sort of color blender tool in CS4? By color blender, I mean something that will easily let me pick two separate colors and generate a range of colors that are between them. The tool at http://meyerweb.com/eric/tools/color-blend/ is an example of a program that does what I'm hoping Photoshop can do.
Is there a way to simultaneously view my canvas both zoomed in and at it actual size as I draw? This is mainly for pixel art, where the art close-up can look really different from the actual product. A little actual-sized canvas in the corner of my screen that updated as I made changes to the art in zoom in would save me the time I spend fiddling with magnifying glasses.
Is there was way to keep the smudge tool at full opacity? When using it, smudging edges of color onto a blank space makes them start to get transparent. As of now I just get rid of it by multiplying the layer a few times and then merging, but is there a way to disable that?
If there are no definite ways to do these things, any suggestions or guides you know of would be useful too. Thanks!

Hello!
Select the gradient tool, it is an alternate tool to the paint bucket one (Hit Shift+G until you see it replace the Paint Bucket tool)
Double-click on the gradient you see in the option bar, you will then get the gradient editor http://help.adobe.com/en_US/photoshop/cs/using/WSfd1234e1c4b69f30ea53e41001031ab64-77dfa.h tml
Double-click on the first color stop to get an eyedropper, sample your first color, do the same with the end one, and the second color.
Once your gradient is created, you'll be able to lay down a gradient, and pick the middle color with the eyedropper tool.

ID all versions, both platforms: Transparency Blend Space

Under the Edit dropdown menu we have a "Transparency Blend Space" option which allows for two choices: Document RGB or Document CMYK. I need to select one of those choices programmatically, based upon input from the user.
In the documentation, I have found hla_TransparencyPreference, with a member function called SetBlendingSpace, and two enums, to wit: kRGBBlendingSpace and kCMYKBlendingSpace. I do not, however, see any examples of how they are used.
Has anyone used this obscure object and if so, would they be interested in sharing a snippet of their code which shows how to use it? I would greatly appreciate finding out.
TIA!

Have a look at kXPSetPreferencesCmdBoss, especially the IID_IXPSETPREFERENCESCMDDATA.

Transparency preview - color faded

Hi,
I used PSD images (based on a transparent layer) and placed in a Indesign document. I used to export to PDF without no problems to preview in CS2. But now, when I open the document in Acrobat professional 8 (CS3) the color of the same tranparent images look faded, or pale. If I open the same document in Adobe Reader 7, no problem, colors are gloss and perfect.
Is there a setting that I have to setup to automatically see the right colors?
All my Adobe suite is synchronized for color settings.
Thank you!!

Just wanted to let you know you are not alone. I've been experiencing the same color issues with multi-page CMYK PDFs with transparency created in InDesign CS3 on Acrobat 8 (I'm running the latest version 8.1.2 on 10.4.11).
Any page that has transparency on it has a huge color shift (It almost looks like it has been converted to RGB). Pages without transparent objects print fine. The same PDF in Acrobat 7 will print with the correct colors on both types of pages.
The PDFs were exported from InDesign CS3 with the Transparency Blend Space set to CMYK and the PDF set to "Press Quality." All images in the document were in CMYK. The PDFs were printed on a Xerox Phaser 7400. Same print settings used in both Acrobat 7 & 8.

Need CMYK for printer... but msg "document is using CMYK blend space..." concerning

Hello all,
I need to create an output PDF that is CMYK for the printer.
I thought I was doing everything correctly until I got this message that was generated when I selected Export (to PDF), "The document is using CMYK space. Colors are converted to RGB in interactive PDF files. To avoid color changes, click Cancel and choose Document RGB from the Edit > Transparency Blend Space menu. Click OK to continue."
So, I think this means that the PDF export is being saved in an RGB color space. Is that a correct interpretation? If so, how do I preserve the CMYK color space because that is what the commercial printer requires? Is that even possible or relevant?
Thank you

You are a lifesaver!
I was wondering what that "interactive PDF" thing was all about. I didn't release that it was simply an Export As... error. I must have inadvertently selected it at some point.
Thanks a million!
