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;
You can easily spot things like that at:

Download and search the chm files.

  • 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.

  • 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.
    IID_IUIDDATA holds the document boss, Command item list is empty.

  • 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

  • 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!

  • 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?

  • Transparency blend color space in Illustrator

    In InDesign there is an option to specify the transarency blend color space. Is there something equivalent to this in Illustrator? If not, how does Illustrator set the colorspace (CMYK or RGB) for transparent elements? In printing we can get all kinds of problems with transparency problems such as boxes, if the transparency space differs from the image's working space. I want to find a way to sync this so the transparency blends all match the working space. Typically I work in CMYK.  Thanks.

    Ai offers you either RGB or CMYK; you decide which in the File > Document Color Mode ( circa v10 ). Transparency doesn't care which space you use in Ai.  If you work in CMYK, then just make sure your swatches and images are CMYK.  But, I think there are other reasons why you'd get boxes in transparent objects.  Take a look at Flattening.

  • Problem with cmyk transparency blending in Indesign cs6

    Hello everyone! Please give me someone an information about this issue...
    All i have in indesign is cmyk color space in all contents, i have set up the transparency blending option to CMYK (edit > transparency blending > cmyk) but when i set the gradient feather on image 1 i have very bad result the transparency is greyscaled not transparent.
    I try everything but nothin works for me, please help me somebody.
    example 1 show the bad result in cmyk blending transparency
    example 2 show the better result with rgb blending transparency with cmyk contents !!!
    why i can not set the cmyk transparency blending option? because i have bad result and i do not uderstand that

    please explain me the difference in this proces because i do not understand that...
    The effect of transparency changes depending on the color mode, that's why you get this warning when you try to change color modes in Photoshop when there is transparency:
    I can replicate your problem in Photoshop by layering transparent black on an RGB and CMYK version of the same image (Here are the 2 example files—http://www.zenodesign.com/forum/TransExample.zip) :
    InDesign makes things even more complex because you can have different transparent color modes on the same page and you can choose different blending spaces. If color is important I take the extra time to create transparency in a Photoshop RGB file where there's more color contol and I can see the affect of a CMYK conversion and flattening.

  • Does anyone know an alternative to  transparency blend  urgent help needed!

    I have been trying to fade watermark for the past 3 days using transparency>blend in QT7.Does anyone know a reliable alternative as I have an inmminent deadline looming. details below :
    When I try to create watermark in visual settings i.e transparency>blend, the watermark disappears when I close properties window and all that is left is a grey box. This even happens when I try to offset the watermark.
    The very anoying problem is that occasionally I manage to carry out task successfully i.e blend watermark, using exactely the same commands!!
    Come on apple, sort this problem out immediately!! Ther is no point in having a quality codec system like h264 if on the other hand there is an intermittent fault in visual settings and you cant carry out such a simple task. QT 7 is not near as robust as QT 6 for this purpose.
    Does anyone have a work around? It would be really appreciated.

    Is the water make a png with a transparency? Use "Add To Selection And Scale."
    Place the watermark on a higher level.
    There nothing wrong with with Qt when placing a watermark.

    Yes watermark has transparency (png and gif files only used) and I use "add to selection and scale"
    The problem is when I use blend slider I can see logo fading in QT file but when I exit movie properties the logo disappears and I am left with a grey box.I have repeated exercise with the same source logo file numerous times using exact same commands with only a 5% success rate.
    I have increased level of gif video track as you suggested but when it went above 0 the watermark disappeared.

    I can make something similar happen. It seems that changing from None to Blend to Straight Alpha does not always make the track change appearance. Other combinations can lead to it staying in other states.
    The easy solution to that is to set the track ink to None, see that it did change, then set it to what you want, and see it change again, and then the effect should take ok.
    I think there may be better performance if your watermark track uses straight alpha rather than blend. You could build more transparency into the PNG if you want it to have a blend effect. Or you could use Straight Alpha Blend. That will make the seethrough parts transparent, and the non seethrough parts will be blended.
    There's another possible issue you may run into, which is that you may be exporting the combined watermark/video out to a new H264 track at low data rate. Depending on the nature of the video your logo make get ruined by the low data rate. Having the watermark in its own track (don't forget to do a Save As self contained, not just a Save) will give the best looking logo, but lesser performance. Exporting to a new movie will have a less good looking logo, but better performance.

  • Changing the colour space on a jpeg image for better quality when uploading to a website

    When uploading my images to my website the quality and colour of the photographs aren't the same. They lose quality etc. I was told to change the colour space to sRGB or something to make it better. No idea how this works and I'm now not sure what settings to have photoshop on, I don't want to edit my images and then for them to be edited wrongly.
    Really need some help, much appreciated.

    File > Save for Web.  Use the 4-up panel to choose the best quality image with the smallest file size to save on bandwidth.  You can test with sRGB enabled.  Click on screenshot.

  • Changing  The Colour Space

    Hi there, as a photographer my photo book printing company has given me instructions to view a photo file in Adobe Reader and compare it with the same file that they will post to me - so that i can make sure that my monitor is properly callibated to match their printing system. They said to make sure that i change the color space to Adobe RGB 1998 or the exercise will be pointless but I cant seem to find where to change this setting in my Adobe Reader. Any help would be greatly appreciated.

    Calibrating a monitor is a question of finding the settings for your
    own monitor. It is absolutely wrong to say " change the color space to
    Adobe RGB 1998" - this is not calibration at all.

    How do i change the line spaces?????

    CSS line-height = space between lines. 
    CSS margin-top = space above the element. 
    CSS margin-bottom = space below the element.
