Testversion of elements12, remove watermark

Hello,
I'm trying out the testversion of elements 12.
It seems like a great software and I think I'll buy it after some tryouts.
Question:
If i create a project in the testversion it will carry a watermark saying this is only the testversion of elements. Will this watermark dissapear  in my testproject if i buy the software?
Or do I have to recreate the whole project in the full version of the program?
// Have a great one!

You can never remove the Adobe watermark from an export from the tryout, be it export to file saved to the computer hard drive or a burn to disc.
But, you can remove the Adobe watermark from a tryout project file (project.prel) in the purchased version.
You open the tryout project in the purchase program and
a. In the workspace, go to Timeline Menu/Delete Rendered Files and the Adobe watermark should be gone
or
b. do nothing, and the Adobe watermark disappears automatically from the tryout project file once the tryout project file is opened in the purchased program.
"a" is classically the answer. But some of us have found "b" to work.
Go with whichever one works for you.
Please let us know the outcome when your schedule permits.
Thank you.

  • How to edit / remove watermarks after the document is digitally signed

    how to edit / remove watermarks after a document is digitally signed ?

    Hello Dave,
    Thank you for your reply.
    I have 2 things to mention.
    (1)It is possible to do so if I open the document in Acrobat 8.
    (2) Is there any work around solution for X-pro ?
        I create a draft document and send it for approval with “draft” watermark.
        I receive it back after approval with the approver’s signature.
      Then I have to remove the “draft” watermark.
      How can I do it?
    Any suggestion will be appreciated
    Thank you.

  • Is there a free software to remove watermark from a pdf document?

    What are the free softwares to remove watermark from a PDF document ?

    No. The watermark is placed there by the owner of the document. Contact them. If you are perhaps referring to watermarks that appear on scanned documents, you need to purchase the scanning program to remove those. In as much as your information is pretty sparse that's all I can advise you on.

  • Non removable watermark

    Dear all,
    Does anyone know how to place a non-removable watermark in a pdf (for me, non-removable means that even a guy using Acrobat Pro will not be able to remove the watermark).
    I need to distribute several pdfs to several guys and be sure that they will not be able to remove the watermark – or similar). I don’t want to use password protected pdf’s.
    Does anyone have other solutions for this kind of problem?
    Thank you in advance,
    Maria

    Your combination of requirements cannot be met. What is wrong with setting password security?

  • Removing watermark from editable pdf

    I am trying to remove a watermark from a client's file to prepare it for translation.
    Background:
    I don't have access to the original file and need to remove the watermark so that individual letters will not get mixed in with body text.
    The watermark is internal version information for the client's use. It is not a copyright nor is it pertinent to the content.
    I am using Acrobat Standard 7, but could move to another computer that has some version of Acrobat Professional. Or could conceivably upgrade to a newer version (though I am under a time constraint).
    The files are unlocked.
    This watermark apppears to have been created in the original software, which is not an MS Office or Adobe product.
    Asking the client for a file without the watermark might be time-consuming as our contact may only have access to the pdf as well.
    I cannot send files out or post examples.
    For the first few short documents, I was having luck using the TouchUp Text tool to click on and delete on each page.
    For those, clicking on the watermark selected the text with a box around it so that it was clear that only the watermark was selected.
    Now I am working in a long document that seems to have no division between the watermark and body text.
    I can delete individual letters if I can restrict what I pick up, but selecting the watermark also grabs the text below it.
    Deleting actually removes body text from the pdf, which I don't think I've ever seen before. (Curious.)
    I understand that removing watermarks should not be easy, but I have to get the text without the watermark somehow.
    Other solutions create extra work and more deadline pressure.
    Any other possibilities?

    I was about to message you directly. Thank you for taking the time to consider this.
    I am able to delete text without redacting it.
    If I work in the standard mode (not advanced edting), my options are only to comment and mark up text, which is exactly what I am expecting from a pdf.
    But if I switch to advanced edit options, I am able to delete text.
    Which would be great if I could delete the watermark only, but I am able to delete content!
    Entire section of the TOC just disappeared, which is something I haven't seen happen even on editable pdfs.
    I do not want to delete anything except the extraneous version information sitting on top of the text I need.
    I usually work in a Word environment, so I want to use those abilities here.
    If I could just make the watermark something along the lines of "locked" or "hidden" it might be enough that it would not be picked up with the text.
    I've started the process of asking for a new version from the original, which very likely lives in a different time zone far away.
    I was just hoping for a faster solution.

  • Remove Watermark

    I need to remove watermark from a pdf already created. I have Adobe Professional 7.0. The instruction said to go to watermark and click remove but I don't have the option.

    Noel,
    I apologize for the inappropriate forum.
    I am not removing trademark information from pictures.
    I am removing internal watermarks from a client's file in order to prep it for translation.
    Asking them to remove the watermark may involve many changes of hands and is last-resort only.
    I am totally in agreement that rights to work should be respected at all times.
    I am simply (desperately) searching for the correct solution to my problem.
    I will originate my search in the Adobe Forums and see if I can find a place where pdf issues are discussed specifically.
    Sorry for any offense.

  • Removing watermark

    Hi everyone,
    I'm kinda new to photoshop, have CS5.
    I have a jpg with a watermark on it that I can't seem to get rid of. It's the sew-classic.com across the page in the image. I was hoping that it would come up as a separate layer in photoshop, so I could just delete it, but it's all on one. Any ideas on a simple way to get rid of it? If it comes to zooming in and going over it with the background colour it won't be worth the effort!

    JJMack wrote:
    Looks like the Watermark is doing its job. If you want the image without the watermark ask the owner for a copy for your use without his watermark.
    Hee, hee, good one - you got me there! This is a (slightly) interesting case. The page is from an old book (1954), which is out of print, but possibly still copyrighted to the Singer sewing machine company. Someone has scanned it, watermarked it, then put it on their website as a locked pdf, that you can't print out. So if you want to print it, or view it without the watermark you have to buy a clean copy of it from them. Perhaps bothering to scan it makes them the owner in their eyes, but I think it's pretty shady to scan and sell someone else's book. If anyone makes money from it, it should be the  company who released the book. So, on principle, I decided to try to get rid of it. If it had been as simple as clicking 'remove watermark' in acrobat, I would have done it. But it's definitely not worth the effort of adjusting it page by page in photoshop! It was an interesting technical challenge, though, and I learned a fair bit.
    I'll reluctantly have to let the forces of capitalism have the victory on this one

  • Can't remove watermark...

    I have a PDF that I need to remove what looks like a watermark across each page, but using the "remove watermark" feature in Adobe X Pro does not remove it. What else can I try to get rid of
    what looks like a watermark on each page?
    Thanks,
    Andy

    This could happen if the file was locked, so you couldn't edit it.
    If it was editable, this is how it would look when you select the object. There would be a rectangular bounding box around it. When you hit Delete, it would disappear.

  • Remove watermark/image from existing PDF?

    I need to be able to remove a watermark from existing PDFs we have stored in a database. This is a legitimate requirement (rather than trying to remove trial software watermarks) as we have > 10 million PDFs stored with a "copy" watermark that we now want to store without the watermark.
    I want to write a service in .NET which can do this programmatically.
    Is there any Adobe SDK to support this.? if YES..please help.!
    Any samples appriciated..
    satish

    The first issue you will face is trying to determine HOW the watermark was
    added.  If it was done in a standard way by a well written tool, then it
    will be easily to locate and remove.  However, if not, you will have your
    work cut out for you.
    Either way, you will not be able to use .NET with the Acrobat SDK for this
    type of low-level operation.

  • Remove WaterMarks / Stamps

    Hi,
    I have added watermarks to a couple of thousand files in our DB - using API, these are status watermarks that should change when the relevant object changes status. I originally intended to do it by keeping the source files (without watermarks) and using them as base for the new watermark, but apparently the source is not always available and i have to remove the watermarks.
    We have Acrobat 8.1 pro, and can remove the watermark easily through UI, but I can't find the way to do it through API.
    I tried and got false on:
    pdApp.MenuItemExecute("COMP:RemoveWatermark")
    Anyone knows how i can do it?????

    thanks for the quick response,
    Actually i have both "addWaterMarkFromText" with status date and "addWatermarkFromFile" with the status stamp. I tried the OCG approach:
    get the OCG's
    Dim OCGs As Object
    OCGs = jsObj.getOCGs(0)
    For i As Integer = 0 To OCGs.length - 1
    If OCGs(i).name = "WaterMark" Then
    OCGs(i).state = False
    End If
    Next
    It finds the watermark OCG on the first page but doesn't turn it off.
    keep in mind that i do want a watermark OCG - but a new one with the new status
    I saw this problem in quite a few forums - but never found any acceptable solution

    There is probably something on top of it. Hold down the command key and click outside of the margins to get the pointer tool then drag select into the document. If you pick up more than one object, shift click on one to unselect it.
    If the object has light crosses on the corners, it is locked:

    Hi,
    Is it a custom developed iView from PAR or standard iView? if it is custom developed iView, you write some java script fuctions using EPCF to autosize the iview. I had done this some time back and I don't have the code right now.
    If you can give more details, I'll check wheather I will be able to help you.

  • I cannot remove embedded barcode from the image. Due to saving compression.

    Hi guys,
    I recreate a thread to prevent confusing on my previous one. Please only reply to this thread thanks.
    Ok, for a start I will give some general description about the application I made.
    I had some problem with the image being compressed while it is saved.
    Because saving an image will cause it to compress and had its pixel valued changed, I could not successfully remove the bardcode that is embedded inside a image(although some of the pixel value will be returned to original normally). I had placed my code below and will accept any opinion that will help me solve the removal of barcode problem.
    What my application does is actually very simple. It will take the pixel value of the area inside the image that will be embed with the barcode first, then it will take the pixel value of the barcode and use the formula (1-alpha * Image pixel value) + (alpha * barcode pixel value) = new pixel value which will contain the barcode that had been embedded inside. The formula works great but when I saved the image the pixel value will change due to compression. On the removal of barcode my application will read every pixel value from the image embedded with barcode (only the area with barcode embedded), then it will go on to read every pixel value of the barcode used for embedding and then use the formula (Embedded image pixel value - (alpha * Barcode pixel value) - (1 - alpha) = original pixel value. But due to the reason that compression will change some of the pixel inside the saved image to drop in its value, the result from the removal formula will be negative and hence caused my result image to become wierd as it will red colors instead of original color on some of its pixel. I tried saving under PNG format which people said to be lossless compression but the result is still the same.
    So I need to ask you guys for opinion or help me find the part where I actually did wrongly and caused the image pixel value to change.
    Thanks. Please proceed and read below for the codes that I used. It is messy and I will sort it out later.
    When alpha is set as 1 the barcode will appear to be overwrite onto the image. But when alpha is set as 0.1 the barcode will appear to be transparent and almost seems to be not there on the image when embedded.
    This is the code I used to retrieve image pixel when embedding:
    public static int[] getImagePixelValue(BufferedImage image, int x, int y){
              //Create an array to store image RGB value
              int[] imageRGB = new int[3];
              //Get height and width from input image
              int imageWidth = image.getWidth();
              int imageHeight = image.getHeight();
              //Get raw RGB value from image
              int imageValue = image.getRGB(x, y);
              //Convert image raw RGB value
              int imageRed = ((image.getRGB(x, y) >> 16) & 0xff);
              int imageGreen = ((image.getRGB(x, y) >> 8) & 0xff);
              int imageBlue = image.getRGB(x, y) & 0xff;
              //Input the converted RGB value into the array
              imageRGB[0] = imageRed;
              imageRGB[1] = imageGreen;
              imageRGB[2] = imageBlue;
              /*//Print out the pixel value to check
              System.out.println("Image red pixel: "+imageRGB[0]);
              System.out.println("Image green pixel: "+imageRGB[1]);
              System.out.println("Image blue pixel: "+imageRGB[2]);*/
              //Return image RGB value
              return imageRGB;
    }This is the code I used to retrieve barcode pixel for embedding:
    public static int[] getWatermarkPixelValue(BufferedImage watermark, int x, int y){
              //Create an array to store watermark RGB value
              int[] watermarkRGB = new int[3];
              //Get height and width from input watermark
              int watermarkWidth = watermark.getWidth();
              int watermarkHeight = watermark.getHeight();
              int watermarkValue = watermark.getRGB(x, y);
              //Convert watermark raw RGB value
              int watermarkRed = ((watermark.getRGB(x, y) >> 16) & 0xff);
              int watermarkGreen = ((watermark.getRGB(x, y) >> 8) & 0xff);
              int watermarkBlue = watermark.getRGB(x, y) & 0xff;
              //Input the converted RGB value into the array
              watermarkRGB[0] = watermarkRed;
              watermarkRGB[1] = watermarkGreen;
              watermarkRGB[2] = watermarkBlue;
              /*//Print out the pixel value to check
              System.out.println("Watermark red pixel: "+watermarkRGB[0]);
              System.out.println("Watermark green pixel: "+watermarkRGB[1]);
              System.out.println("Watermark blue pixel: "+watermarkRGB[2]);*/
              //Return watermark RGB value
              return watermarkRGB;
         }This is the code I used for merging the image pixel and barcode pixel to get the embedded pixel value:
    public static int[] getEmbeddedPixelValue(int[] imagePixelValue, int[] watermarkPixelValue, double alpha){
              //Create a object to hold embedded pixel value
              int[] embeddedRGBValue = new int[3];
              //Change image pixel value into double calculating equation
              double imgRedValue = (double) imagePixelValue[0];
              double imgGreenValue = (double) imagePixelValue[1];
              double imgBlueValue = (double) imagePixelValue[2];
              //Change watermark pixel value into double calculating equation
              double wmRedValue = (double) watermarkPixelValue[0];
              double wmGreenValue = (double) watermarkPixelValue[1];
              double wmBlueValue = (double) watermarkPixelValue[2];
              //Equation for embedding image and watermark together
              double embeddedRed = ((1.0 - alpha) * imgRedValue) + (alpha * wmRedValue);
              double embeddedGreen = ((1.0 - alpha) * imgGreenValue) + (alpha * wmGreenValue);
              double embeddedBlue = ((1.0 - alpha) * imgBlueValue) + (alpha * wmBlueValue);
              //Changing embedded value from double to int
              int embeddedRedValue = (int) embeddedRed;
              int embeddedGreenValue = (int) embeddedGreen;
              int embeddedBlueValue = (int) embeddedBlue;
              //input the embedded RGB value into the array
              embeddedRGBValue[0] = embeddedRedValue;
              embeddedRGBValue[1] = embeddedGreenValue;
              embeddedRGBValue[2] = embeddedBlueValue;
              //Return embedded pixel value
              return embeddedRGBValue;
         }This is the code where I used for the embedding process:
    else if(target == embedButton){
                   String xCoordinate = JOptionPane.showInputDialog(embedButton, "Enter coordinate X", "When you want to embed the watermark?", JOptionPane.QUESTION_MESSAGE);

    Follow this link to have a look of the result I see in my application when I got the barcode embedded into the image I selected:

    Follow this link to have a look of the result I see in my application after I got the barcode removed:

    As you can see from the link, after I remove the barcode from the image. Some of the pixel actually went back to normal in the barcode area when the the barcode is embedded into the image. But some pixel in the barcode area had its value changed due to compression when I save the image file I think.
    Anyone can help me find out the problem?
    Thanks.

    I suspect the problem lies in the code when I save the image. Because people said that PNG was loseless compression but when I saved in PNG some of the pixel went back to normal while some did not. This is obviously the cause from changing of pixel value when I saved the image.You are almost certainly wrong. This is trivially easy to check. Print out the color of a certain pixel immediately before you save it. Open the saved PNG in your favorite image manipulation program and check the saved value of that same pixel. When you re-load the saved PNG, print out the color again. It should be unchanged.
    Thanks you for trying to help me spot the problem but the formula is correct. The alpha value i used in my application is used to set the transparency of the barcode that will be embedded in the image. Hence, when alpha = 1 the new pixel value should be the barcode value. ^^The formula isn't wrong, it's just not doing what you think it's doing. Remember that you're working with ints here, not floating point numbers, so they have finite precision. When you case from double to int, fractions are dropped. As morgalr pointed out, your formula is:
    (1-alpha * Image pixel value) + (alpha * barcode pixel value) = new pixel value You didn't show us the code for getOriginalImagePixelValue but I imagine it's:
    original pixel value = (new pixel value - alpha * barcode pixel value) / (1 - alpha)On a piece of paper, take alpha = 0.9, image pixel = 17 and barcode pixel = 100. Calculate out what you should get for new pixel value and then calculate what you should get for original pixel value. You will find they don't match.
