Drop shadow failing to blur with high document raster effects settings DPI

I have a 1024px square artboard (in Illustrator CS6 16.1.0 running on Mountain Lion 10.8.1) with some fairly simply artwork that has a drop shadow effect applied, shown here at 33% with the Document Raster Effects Settings (DRES) resolution set to 150 DPI:
If I change the DRES resolution to 300 DPI, the blur on the drop shadow disappears entirely:
If I leave the DRES resolution at 300 DPI, but resize the image to make it a little smaller, the blur on the drop shadow comes back:
I’ve wasted several hours already trying to get the desired blurry drop-shadow on the full sized image with the DRES resolution at 300 DPI, to no avail. Does anyone have any idea as to what is going on here, and what I can do to solve this problem?
Many thanks in advance.

The Gaussian Blur was rewritten for CS6 and should probably be similar in CC. Your screen shots did not get properly attached. Can you try again to attach them using the Camera icon in the reply window tool bar?

  • Document Raster Effects Settings? I can't find it!

    Hello,
    I am using Illustrator CS5. I am looking for the document raster effects settings. I think they are at 72DPI because my drop shadows on my images are pixelated when I print out my design.
    I want to change the document raster effect to 300DPI.
    I googled it and in CS4 it was under the effects menu but in CS5 I don't have the effects menu anymore. It is under Objects->Effects but I don't see the document raster effects settings anywhere.
    Any ideas?
    thanks,
    PedroAlberto

    You are showing us a screensht of InDesign which is different from Illustrator.
    I do not believe that ID has a raster effects setting.
    This is the Illust6rator Frum you are mixing up the tw different applications, they are not the same.

  • Document Raster Effects Settings

    How do I permanently change the default Document Raster Effects Settings from 72 ppi to 300 ppi in Illustrator CS2 for Windows XP?

    Open the file called "Adobe Illustrator Startup_CMYK.ai" located at C:\Program Files\Adobe\Adobe Illustrator CS2\Plug-ins. Make changes to the Document Raster Effects Settings & save the file, replacing the original file. Take a backup of the original file so that you can revert to it later on, if need be.

  • Help with Resolution/Document Raster Effects

    I am wanting to upload my logo to my credit card company to put on the face of my new card.
    obviously this will be small in size (1.5"x3") but the cc company requires the upload be at least 400pixels x 400pixels.
    I don't want to upload a 13"x6" because they shrink it down and it loses quality.
    I have tried changing the Document Raster Effects to 300 ppi, but the rulers still show 72 ppi and when I save it to jpeg, it is only 72 ppi.
    How can I get a 1.5" x 3" document to save with 450px by 900px dimensions?
    Here is a link to the file: http://buffalomooncoffee.com/images/small_logo.ai

    I am not certain I understand the need to pen this in photoshop and all this other stuff but you can simply export it as a jpeg.
    I am going to show screen shots because this comes up all the time and everyone gives strange instructions.
    1 Make the art and artboard 3 inches wide constraining the proportions (works out to 3 x 1.37) the art is of course a little smaller.
    2. Export it and choose jpeg as the format (select use artboards)
    3. in the jpeg options dialog choose maximum quality and then choose for resolution high, which is 300ppi.
    Now you have a jpeg that is 3 x 1.367inches at 900 x 410 pixels

  • Warning: the document raster effects resolution is 72 ppi or less

    How do I address / fix the issue that leads to this WARNING when saving my Illustrator CS6 file? All embedded images are 300 ppi.

    Kristen,
    The warning has nothing to do with your images.
    It is simply a statement that tells you that you have not set Effect>Document Raster Effects Settings higher than the default screen value of 72 PPI.
    If you have no raster effects applied to your vector artwork there is no need to worry.
    If you have, you should consider which value is suitable.

  • Indesign CS4 drop shadow fail

    I have numerous .psd photos in on each page, all closecropped in Photoshop using a mask.
    I have applied a drop shadow to these in Indesign and most look great  - but the odd one has the dropshadow cut off abruptly for no apparent reason.
    Any ideas why this would happen? I can't seem to fix it.

    There is a much easier workaround that doesn't require altering your image files at all: simply draw a basic object (eg an empty square) on the pasteboard to the right of the page, then group your image with the object and apply your Drop Shadow effect to the group - this forces the shadow draw error off the page, without adding more data in the way that extending a Photohop image canvas would.
    It's not ideal, but then again ideal would be Adobe publishing software that actually works the way it's supposed to...
    Also to BobLevine, there is a very easy way to make shadows in Photoshop files blend correctly in InDesign: first create your Photoshop file with two layers, Object and Shadow. Place the .psd onto your InDesign page, and Copy (NOT Cut) it to the clipboard. Select "Object Layer Options" and turn off the Object layer, then set the image to Multiply. Paste In Place to put a second copy of the image file on the page directly over the first one, select the second image, and this time in Object Layer Options, turn off the Shadow layer leaving the Object blending normally. Finally group your two images.
    Voila, one .psd in InDesign with a correctly blending drop shadow.

  • Drop Shadows not showing up with iweb 2.04 in firefox please help!

    Drop Shadows on my frame are not showing up with iweb 2.04 and firefox please help!
    They show up with safari but not firefox. I've read that publishing to mobile me solves it but I publish to my hard drive and ftp to my host (not mobile me).
    Thanks for any help

    Drop shadows, borders etc are a bad idea in that they increase the file size and the download time of your page.
    Create your image, drop shadow etc on your iWeb page, take a screenshot, crop it and replace the original image with the, much reduced, JPEG>
    Example....

  • CS6 Drop shadow will not blur.

    I did the update it worked twice this morning and bam no blur on the drop shadow. I shut down completly and rebooted still not working. Any suggestions?

    That is basically what I am doing it will work a few times and all of a sudden it stops again. Delete prefs and it works again. You can see when it stops that the gaussian blur is not being applied.

  • Change document raster effects to 300dpi??

    Using Illustrator CS
    Am up against a deadline for an image to be printed at 300. Made image using default of 72 dpi. As you would expect and I did not, when coverting to 300 dpi, the appearance of my gaussian blurs are diminished to the point where they can barely be seen, and instead of subtle blurs I have sharp lines. I understand that the correct way to do this would have been to work in 300 dpi all along, but it is rather late for that. Short of redoing all my raster effects, is there a way to preserve the appearnce of the gaussian blurs at 300 dpi?
    If I do need to go back and redo all my effects, is there a shortcut or method or script I can use to speed this process up?
    Help, please? Clock is ticking and I am not working on a new machine.

  • Drop shadow turns to hard shape in high resolution?

    I have a drop shadow that looks fine when the document raster effects is set at 72 dpi, but at anything higher turns into a hard shape with no blur/shading. Is this a memory issue, and is there a workaround for it? Thanks for any ideas.

    The Gaussian Blur was rewritten for CS6 and should probably be similar in CC. Your screen shots did not get properly attached. Can you try again to attach them using the Camera icon in the reply window tool bar?

  • Having a strange problem with Drop Shadows in Ai CS5

    Hi there Adobe experts!
    I have tried eveything... this is my first post here, but it's my only hope. I have a project where I apply drop shadows to linked images to give a sense of depth. A few days ago, the drop shadows just stopped feathering. It doesn't matter what the blur is set to, its just one colour. Transparency still applies. Here's the kicker...I can open files with applied drop shadows to them and they look fine. But if I try to edit that existing shadow, even by 0.0001 of a pt, it will lose its feathering.
    I've deleted the AiPrefs file, and played with just about every setting in document raster effects settings. I have no clue what would cause this.
    Oh, and whatever the issue is, it starts in my computer, and then attaches to the files... I sent the ai file to a friend, and when he tried to add drop shadows, they screwed up on his machine too. But it isn't the file. I've attached a brand new (and CMYK, just to see if that would make a difference...) file of a sphere showing the problem. Even with the blur super high, the shadow remains flat and monochromatic.
    Any geniuses seen this before or have a remote clue how to solve this one?
    Thanks in advance,
    Luke

    All my ram is tripple channel DDR3, same clock speeds, but some is 2GB and some is 4GB.
    I just pulled the 2GB sticks (which I had in originally) and left in the 4GB sticks (the ones I recently purchased) and the problem goes away. It's quite odd, I've never had a problem like this before with any other application. I know it's not the best thing in the world to have different types of RAM installed, but my motherboard supports it and I've never had a problem doing it before.
    I would be interested to see if this problem is reproducable in the OP's senario, or if this problem can be reproduced by others.
    Conclusion: the 2GB sticks work on their own, and the 4GB sticks work on their own. I definitly would not call this a hardware problem, it's an adobe problem and they need to fix their software.

  • Drop shadow problem with Illustrator CS5

    I've used drop shadow several times with no problems in both photoshop and Illustrator... currently I'm dropping a white shadow onto a black background and although the shadow drops correctly around the object I've noticed that there is some sort of extra white blur that is happening several inches away from my images reguardless of what shape they are. Let me know if a file would help and I can email an example of the problem. Thanks

    Wade, This does look like the exact problem I'm having. I do not want to make a clipping mask because I have around 20 pages with numerous images on each page of varying sizes... I tried- Effect/Document Raster Effect Settings, Under options I played with a couple different settings but none seem to have fixed the problem... There is a check box for;
    Anti-alias
    Create Clipping Mask
    -Add _____ in. Around Object
    Preserve spot colors
    I'm not familier with these settings and didn't know what you were recommending I change exactly?
    Thanks again for the help

  • DROP SHADOW EN ILUSTRADOR....AYUDA

    Que tal, saludos desde México, quien me puede ayudar en saber como configuro la sombra que se le pone a los objetos (DROP SHADOW), es decir, mayor calidad o resolucion a la sombra, ya que al imprimir ciertas cosas se ve pixeleada. EFFECT/SYLIZE/DROP SHADOW
    Se los agradeceria muchisimo !!

    Hola Miguel, para solucionar tu problema debes hacer lo siguiente:
    1) En el menu de efectos te encontraras con una opcion de "DOCUMENTS RASTER EFFECTS SETTINGS" abrela y asigna la resolucion que deseas para tu sombra, para impresion offset es recomendable 300 dpi.
    2) Ten en cuenta que si asignas una sombra a un vector y luego modificas el conjunto de tamaño (o sea el vector y la sombra los aumentas de tamaño) tiende a cambiar las propiedades de la sombra que es un bitmap generando el efecto pixelado en la sombra, es preferible aumentar el tamaño del vector hasta su punto definitivo y luego aplicarle la sombra.
    Espero que te sirva de algo...
    Saludos

  • AI effects: Feather versus gaussian blur? which is raster or vector?

    i`m looking at feathering versus blurring. both in illustrator effect drop down menu.
    from what I I understand the blur/gaussian blur under photoshop effects (in illustrator) will pixelate the edge gradation, but the illustrator effect "feather, will keep it vector, is this correct?
    from sample here they both look the same to me, and I noticed the feather effect was gaussian blurring the edge anyway to produce its result,,
    from what I can see I should be able to make either of these as large as a billboard and they would both still be smooth gradients? or would the gaussian blur result in pixelation unless I had the vector object sized correctly in the document in the first place to suit the billboard.
    what I am trying to ask is how do they work,
    my take is the AI "feather" will allow resizing of the vector object shape to any size and not be pixelated on print output,
    where as the gaussian blur PS effect, you would need to make sure your object is correctly sized on the correct document size to ensure that it prints smoothly.
    any feedback is good,....

    wildbirdsketch,
    actually can I confirm, both produce a raster gradation to soften the edge, so its no longer vector once you apply a blur or feather correct?
    It is, but with raster effects. 
    asking because if I create a blur/feather, I will have to consider the resolution  or not as again I`m assuming no because each time I resize the object the effect recalculates itself as necessary to create the right blur and resolution for that size.?
    As long as you keep the Effect>Document Raster Effect Settings the same, the resolution of raster effects will remain the same,
    and when these vector objects print (in general for AI), i`ve never known, do they print as Vector or does the RIP turn them all into raster anyway?
    Indeed.
    just confused on this, I`m guessing their only vector while in illustrator, but once going through the printer it will all be raster  via the RIP if thats correct,
    Indeed.
    its just that vector allows you to scale it to the required output size prior to print and have it print crisply without having to focus on resolution or resampling methods correct?
    Indeed.
