Transparent signature in Acrobat 9.0

I have been trying to figure this out for several months now. I sure hope someone can help me out. I need to create a graphic signature with a transparent background for use in a pdf document. I have created a .png file with transparency, and all the background removed. The problem comes as soon as I bring it into Acrobat to create the signature, it adds a white background to it. I have tried every setting I can find but nothing seems to work. Is this a limitation of Acrobat Standard 9? I have gone through a dozen tutorials and the same problem occurs everytime I go to create the stamp or digital signature. Thanks.

Thanks for the help, unfortunately I already ran across that writeup but still no luck. Actually, the link partway down the page that describes where I am stuck is broken. Creating the transparent image I have no problem with, it is when I bring it into Acrobat that it loses the transparency. I used photoshop elements 8 to create a transparent .png, a .gif, and a .pdf. All show up correctly and transparent in elements, but none show up correctly in Acrobat. As soon as I try and use it as my signature it gives it a white background. I tried stamps as well, with the same result.
Good to know that Acrobat standard can do it, but for some reason I am missing some crucial detail here.

Trying to capture signature for Acrobat

I scanned my signature and saved it as a tiff. So then opened it in PS CS4. Then cropped it and tried the magic wand to select around it to eventually invert (blue ink on white background) but it wouldn't keep selecting around (holding shift key and clicking to keep selecting) it like I have done/accomplished many times before in PS 7.0 - I saved it to web/devices as jpg too but same thing. Is there somethig I'm doing wrong where it won't keep selecting around the image? I want to then invert it so I have a transparent image that I can change colors and stuff? My goal is to create a custom signature for Acrobat.
Thanks for your help!

Another possibility is resetting the Magic Wand tool from the drop-down menu in the Options bar.
If all else fails, try resetting your PS preferences as described in the FAQ.

You either have to physically delete (or rename) the preference files or, if using the Alt, Ctrl, and Shift method, be sure that you get a confirmation dialog.
This resets all settings in Photoshop to factory defaults.
A complete uninstall/re-install will not affect the preferences and a corrupt file there may be causing the problem.

I can no longer "send for signature" in Acrobat XI after Echosign update.

I can no longer "send for signature" in Acrobat XI after Echosign update. Now when I click that option, up comes a box that asks me to enter the recipients email and their name. I did a test and it send it to the recipient without me being able to add signature boxes for the recipient in Echosign. It used to upload the document to Echosign and then I could position the recipients signature boxes before sending to them for their signatures...By the way, I use a Macbook Pro.

I want to clarify. When I make a document (in my case a real estate form) I click the "sign" tab in Acrobat XI then "get others to sign." A blue box pops up and says "uploading to Echosign." This is normal so far. At this point, before the recent Echosign update, my browser would automatically open up to the Echosign website and show my document that was just uploaded. Then I was able to position signature boxes for the recipients. Now what happens is a box comes up on my screen and just wants me to send the recipient an email. See photo...

Digital Signature crashes Acrobat 9 Pro

An error occurs when trying to Sign any PDF document, even when opening a very simple, one word (Times New Roman text only) PDF document. After opening the PDF in Acrobat Pro (WinXP Pro SP3), selecting Sign, Sign Document, Acrobat allows proper placement of the signature box, and accepts the password for the selected Signature ID. When <Sign> is then selected, Acrobat offers to save the document, and when the save location (any location) is selected, Acrobat returns the error below.
Adobe Acrobat 9.3 has encountered a problem and needs to close. We are sorry for the inconvenience.
Error Signature
AppName: acrobat.exe AppVer: 9.3.2.163 ModName: acrobat.dll
ModVer: 9.3.2.163 Offset: 00135fb9
The same source PDF document can be modified, or password protected, and then saved without a problem. Only when a digital signature is applied does the error occur. Acrobat has successfully Signed and saved documents on this PC previously, but starting experiencing this error about week ago. I have uninstalled Acrobat, reinstalled ver. 9.0 and applied the two updates to 9.3.2, and have generated new Digital Signatures, all with the same resulting error when signing a document. The new, signed PDF document is actually created, and a Digital Signature is found in the document, but is invalid, reporting:
Error during signature verification.
Signature contains incorrect, unrecognized, corrupted or suspicious data.
Support Information: SigDict /Contents illegal data
I have tried the troubleshooting steps in http://kb2.adobe.com/cps/403/kb403613.html, but without any progress; the error continues to remain. Any advice on how to resolve this will be greatly appreciated. Thanks.

Hi Mike,
After the Save As operation was done, did you see the signature appearance displayed in the signed signature field before you closed the doc? And if did see the signature appearance, did you happen to notice if there was a green check mark displayed in the blue message bar at the top of the file?
Thanks,
Steve

Place signature & DigSigHFT (Acrobat Plug-in [C++])

Hello All
I have problems with operation "Place signature" in Adobe Acrobat Prof
I get sigField==null in callback function DSNewSigDataWithParams after user place signature inside document with help of "Place signature" button.
I see only DigSigBBox in parameters with size of new signature.
How I can get position of new signature from Acrobat?

Example of code:
ACCB1 DSSaveType ACCB2 DSNewSigDataWithParams(DigSigNewSigDataParams sigParams, void **pSigData)
if (CosObjEqual(sigParams->sigField, CosNewNull()))
//I need to create new signature field here, but I don't know positon of new signature in document
//I only know size of new signature (I can get it from sigParams->bb)
1. Is it bug in Acrobat?
2. Maybe can I use other callback functions to get position of new signature?
3. Maybe must Acrobat create signature by self and put it to DSNewSigDataWithParams?

Are accessible multiple signatures in Acrobat XI Pro possible?

I'd like to access two saved signatures in Acrobat XI Pro but I haven't found an easy way to do it in order to use them for signing documents. Is this possible? If so, how? If I haven't created a digital ID or a digital certificate are my signatures considered digital signatures?

I am not sure what you mean by "access saved signatures." My guess is you've used a stamp or some other method of adding what is essentially a picture of your signature.
Anyway, to sign with a real digital signature you need to create a Digital ID. That kind of sig allows you to create a signature appearance and certificate that you can reuse. You'll also be able to review and control changes to the document over time.
Alternatively, you can use the EchoSign service which also has a host of useful features.
HTH,
Ben

Problems creating a transparent signature.

Hi,
I am trying to create a transparent signature, but whenever I complete the steps in this forum below the signature is fuzzy. I've also attached an example showing the problem.
Thanks for the help!

The image is probably using JPEG compression as a result of getting converted to PDF, but you can control this through a preference setting: Edit > Preferences > Convert to PDF > TIFF (or PNG) > Edit Settings > Grayscale (or Color) > ZIP (or higher quality JPEG/2000)

Cursive signature in Acrobat Pro X

1. I need to create a cursive signature in Acrobat Pro X - is there a way to do this without having to upload another file?
2. I created a digital ID but can't locate it with the browse function.

You'd normally create an image (or vector graphic) of your signature in some way and use it as the source for the signature appearance. Acrobat doesn't prompt you to hand-draw a signature and use it for an appearance.
To find the file, you can open launch the "Digital ID and Trusted Certificates Setting" dialog, locate the digital ID file in the list (Digital IDs > Digital ID Files), click "Certificate Details", Details tab, Certificate Data > Private Key <see details>
and it will show where the .pfx file is on your system.
I don't recall how to do the first step in Acrobat 10, but in 11 they changed it to: Edit > Preferences > Signatures > Identities & Trusted Certificates
and in Reader 10 it's under: Edit > Protection > Security Settings

Certifying and Locking file Invalidates Certification and Signatures in Acrobat 9.0.0

I am running Adobe Acrobat Professional 9.0.0. After creating a PDF document from within Microsoft Word, and it opens in Adobe Acrobat Professional, I performed the following steps:
Select Forms => Add or Edit Forms.
Select the digital signature tool and create three forms.
Select Close Form Editing.
Right click the first form and select Certify with Visible Signature.
Set Permitted Actions After Signing to Form Fill in and digital signatures.
Select Sign.
Save the document, replacing the original file.
Click on the second field, to sign it, and select sign.
Save the document, replacing the original file.
Click on the third field, to sign it.
Select Lock Document After Signing, and select sign.
Save the document, replacing the original file.
I then find that the certification and the first signature are invalid. Only the last field to be signed is valid. Why is the previous signature and certification invalid? This only appears to occur if I both certify and lock the document when signing the last field. If I view the document in Adobe Reader 9, the result is the same. However, if I view the document in Adobe Reader 8 the certification and all the signatures are valid, as expected.
Any assistance much appreciated.

David,

Thanks for the responses Geo & Atin,
Geo,
Maybe I'm misunderstanding what you're saying, but http://www.adobe.com/devnet/reader/articles/reader_compatibility/readercomp_digitalsignat ures.pdf seems to indicate otherwise. Specifically:
"In Acrobat 9, when additional signatures are applied to a document, the earlier signatures continue to have the Valid status, subject to the certificate validation rules that have been part of Acrobat's signature processing for a number of releases.
In Acrobat 8, all signature appearances except the last one would have changed their status to "Valid with subsequent changes" (green check with a yellow warning triangle) if their certificate was still valid."
So I read this that in neither version should the signature be "invalidated" by simply applying another signature, but in version 8 it showed the triangle warning, and in version 9 nothing would change. Indeed nothing does change in version 9 and it works EXACTLY as described above providing I don't both certify AND lock the document. I still don't understand why just the extra locking step violates the "certificate validation rules".
Atin,
I carried out the steps that you described, and it works thank you. I notice that the lock option is not present when I sign the last field now, but presumably this is because by the time the last field in signed, with the settings you describe the document is effectively fully locked anyhow?
Now my problem is, is there any way of setting up templates of the signature fields laid out in the correct position, with the settings that you describe that I can use repeatably on many documents? I wish to use this function to electronically sign technical drawings which are drawn in a CAD package using a template based title block with 'drawn by', 'checked' and 'approved' fields etc. Each drawing may also have many sheets, each with the same fields in the title block. My concern is that to manually place digital signature fields in these 3 spaces in every title block after creating the PDF's, and then apply the settings you describe before certifying (at 'drawn by') and distributing for sign off at 'checked' and 'approved' is going to be a very time consuming and inefficient process. Am I missing something?
Regards & thanks again,
David.

Adding a digital Signature in Acrobat X Pro

A recent update seems to have altered the digital signature. Before there was no problem and I used the signature I created in Acrobat 9 after upgrading to X Pro. But yesterday (after the update) I was asked for a password for the first time. Eventually I deleted the ID and tried to create a new on but cannot. I follow the steps - a new ID, then a new PKCS#12 file; I fil lin the details requested then on the next page it asks for a file location and password. I accept the default location and type in a password but after the enter I get a message that the passwords do not match.
How do I sole this or am I doing something wrong?

Do you enter the password twice? People have reported that the second password field isn't visible when using a low resolution screen.

Acrobat 9,10 failing to validate digital signature while Acrobat 8 validating it.

I am facing an issue while validating a digital signature. I applied a certified signature with “Annotation, form fill-in, and digital signatures” but
when I apply Redaction “find and permanently remove” on a digitally signed document, Adobe Acrobat 9 and 10 complains that signature is Invalid But Adobe 8 is validating it. I have analyzed that Adobe Acrobat applying Redaction in append mode and original content of signature remains unchanged after Redaction.
Can someone let me know what should be the actual behavior?
Why Adobe Acrobat 9 and 10 failing to verify the signature even Adobe Acrobat keep enable Redaction which means it is allow to apply in a certified signed document with “Annotation, form fill-in, and digital signatures” option.
Prompt responses are greatly appreciated!!

When you sign, you should see where you can select the signature appearance name from a dropdown in the dialog.

PubSec Digital signatures in Acrobat 9

Hi,
i m developing a digital signature plug-in, PubSec, to be specific. My plugin will, hopefully, digitally sign open pdf, and also able to verify them. The signature i am creating will be standard so that any other plugin, including Acrobat's own, can also verify it, and my plugin can verify others too. For this, i will leave the Filter unset and only set subfilter appropriately.
Now, when implementing the signature creation and verification callbacks i found it very difficult, and in some cases am stuck, while getting required information from the provided arguments of the callbacks. For instance, from this structure "PSSigValidateDialogParams" i want to extract information such as:
- signature's verification status
- signer's certificate
- reason location, etc.
But so far i can only get the verification status as:
ASInt32 sigValDigest = ASCabGetInt( sigValCab, PROP_SigVal_Digest, kDSSigValUnknown );
ASInt32 sigValTrustFlags = ASCabGetInt( sigValCab, PROP_SigVal_TrustFlags, kDSSigValUnknown );
ASInt32 sigValId = ASCabGetInt( sigValCab, PROP_SigVal_Id, kDSSigValUnknown );
And i dont even completely understand what each of these mean. And i cannot get the rest of the info from the structure as well, as i cant find any discription about them in documentation. I did find a "Digital signature API Reference" document for acrobat 6, but none for acrobat 9. And even in acrobat 6, there is no description for most of the functions and structure, just the prototype.
Please help me get the above information from the PSSigValidateDialogParams, or atleast point me towards the documentation of the digital signature api reference for acrobat 9. Thanks

Problems getting multiple digital signatures in Acrobat Reader form

I have a Word document that I converted to a form in Acrobat 9 Pro. I added two separate digital signature fields, one for a conference presenter and the other for the conference planner to sign. There are also a number of text fields where presenters give bio information. I saved the document using the Extend functionality so that a user who only has Acrobat Reader would be able to fill in the form, sign/save it, and then send it on to the conference planner. The first part is working fine. However, once the first user signs/saves the document, the extended functionality goes away. When the conference planner receives the document, it is essentially locked. She cannot sign and save.
Is what I'm trying to do possible? I feel like this would be fairly commonplace, but I may be going about it the wrong way. Thank you for any pointers.
-Brian

Hi Steve,
I have met similar problem. Using Adobe 9.4 I have prepared document with three signature fileds. I did signature in one of the field and then did extension to Reader. When I checked the propierties of document it occured that signing was not allowed. I couldn't sign it second time (not saying of Reader's user).
Is there missing any plug-in or something is wrong with a configuration (mentioned "Nothing has happened when signed" was set up)?

Multiple Digital Signatures in Acrobat 8.1

Hello to all, I am trying to have two people place two (2) digital signatures (using the method: Advance Menu Item | Sign & Certify | Place Signatures) on a PDF document.
There are no problems placing the first signature, but when the second person adds theirs, the first signature ends up having a yellow exlamation mark over the green check mark with the statement: "The revision of the documnet was covered by this signature has not been altered; however there have been subsequent changes to the doucment.".
I must have both signatures showing "green check marks", otherwise my document can be rejected when I submit it. I have version 8.1 of Acrobat and need a solution fast as I need to submit this document tomorrow.
Thanks in advance for any help provided.

I believe this behavior was changed in Acrobat 9.
