Signature of a PDF/A with a JPG image, invalid compliance

I'm trying to sign a PDF/A document.

I can't do without for as much invalidate the PDF/A compliance with Adobe Acrobat. So I use our tool to sign the file.

When I use a BMP as the beautiful graphics of the signature, the file remains compatible, if we use a JPG image compatibility fails.

The only difference between the two files (compatible and compliant) PDF/A is the different XObject object (one is simple pure bmp object, the other is a jpg, with always DCTDecode etc.).

I would like to know if there is a way I can make the JPG image to work without to invalidate the PDF/A compliance, or is this inevitable, like a JPG object has attributes that contradict the basic concepts of the PDF/A format.

Thank you

  • How to create a camera profile that works with a JPG image with my color chart to check inside? [was: color Checker chart.] Really need help]

    I got a color chart to check. It came not with any software whatsoever. I shoot my images in JPG format. I know it's not really ideal but I'm on a tight budget and don't have the money for a digital SLR cameras that shoot raw. Is there anyway that I can always create a camera profile that works with a JPG image with my color chart to check inside? My table also includes RGB values below each color. Maybe I can match each color in the photo these values manually? If so how is this done?

    Thank you

    I've never seen software that does what you ask for JPGs, only RAWs.  The main problem is that any profile or adjustment is calculated according a JPG of a particular chart photo would apply to the other JPG photos with the same white balance.

    Jpg does not use "camera profiles" anyway in Lightroom, the profile is always integrated.

    There is a product that allows to calculate the HSL cursor offset values given a JPG photo their own table owner who looked like a color checker, but had two lines reversed so the software could not be used with a standard-checker color, unfortunately.  Now their table has twice as many patches (48), and looking at it on their site I'm not too sure that it does not always work with JPGs or if she's just raw files, now.

    The graphic and software are called SpyderCheckr of Datacolor.  There are various software that do different things, but none are using a ColorChecker, so having one is mainly a loss until you get a camera that can take raw photos, so keep a humidity and temperature controlled environment as much as possible until you have the right camera.  You can probably use the grey patches to adjust exposure, but that's all.

    Today you need not a digital SLR to have raw photos, well.  My phone Galaxy S6 with the last update of Marshmallow and the software of camera update will take photos in format raw DNG in Pro mode which I can create custom profiles camera to use a ColorChecker, although the camera is really good in itself, so when I found everything first he could make DNG I took a little but now, I usually just use the camera to make the jpg unless the shot is really important and the lighting is not too hard.  I think that S7 phone's camera is even better.

    What kind of camera do you have?  Sometimes, there are firmware hacks that allow the camera to shoot raw format even if the standard camera cannot.

  • Small rectangles showing that separate pages in PDF MultiPage with Capture of Image analysis?

    I'm having a problem of scanning. I'd appreciate it if someone could explain what is happening and show how to avoid it or how to fix it after the fact. I use a scanner large format HP Officejet 7610, a MacBook Pro running OS X Yosemite, v.10.10.1. I use Apple Image Capture app, v.6.6, for scanning software. I'm scanning of some newspapers, with text and photos on the pages that talk about 11 "x 14-3/4" in size. I'm doing a PDF multi-page, each about 10 percent, with a resolution of 300 dpi. Sometimes, when I scan a single page or several pages, one or more small rectangles of scan appear in the PDF file, following a normal page or between pages. In the Acrobat Reader software, this small rectangle looks like a box of small curious, much less a thumb on one side, and when the PDF file is displayed, the small rectangle is printed, too, as if it were a separate page. Why this rectangle is displayed in my scans? Is it possible to not drop it? After that he was a part of a multipage PDF document, is it possible to get rid of him, keeping the rest of the analysis?

    Hey there @Rudyard , welcome

    I read your post on digitization issues you encounter, and I want to help!

    Please try scanning with HP scanning software to see if it happens to the same problems of quality and if so, try the following steps in order:

    1. Mac OS X: how to reset the printing system
    2. Repair disk permissions
    3. Restart the Mac.
    4. Install the driver full features: series e-all-in-one HP Officejet 7610 Wide format full feature software and drivers
    5. Also install the driver Apple: HP v3.0 for OS X printer drivers

  • Export a page of a document in PDF format with compression settings different

    I think that what I want is not possible, but I don't know until I try...  I have a template that we use a lot in our marketing material that seems not good on the screen during the export of smaller file size.  Is there a way that I could export a PDF file with just that image or the page that it is set to a higher resolution?  It justified for the moment if I export the page separately and combine again in Acrobat afterwards.

    Have you tried playing with the PDF export settings? Specifically, if

    you're the subsampling this pattern, try a different subsampling method.

    For example, if there is a lot of fine lines in the image, try the nearest

    Neighbour to keep those. This can have a significant effect on an image and a

    negligible effect on others, so maybe this is what you need. Just a

    shooting in the dark without actually seeing the images in question.

  • Is there anything I can do to improve the quality of the .jpg image?

    I'm working on a project for a client and the only files that were provided are low quality .jpg images. I already brought up the ppi to 300, but as with all .jpg images, there is only for many this can be done, I'm afraid.

    I just wanted to check with the community to see if there is some advice that I might have missed. I want to make sure you have covered all the bases.

    P.S. I am these cutting and exporting to PNG files. Then maybe there is a way to at least soften the edges of the cut?

    You cannot create information after it has been packed away, but you can remove the checkerboard patterns and artifacts of mosquito with a plugin like "Topaz" DeJepeg https://www.topazlabs.com/dejpeg I use it all the time and can't say I've seen any other plugin do a better job. Its about $30, but they give you a free month assessment. The images are inevitably more soft, but you can always sharpen them.

  • How can I send a PDF (contract) with electronic signature fields to a client which sends the document to its legal service for execution?

    How can I send a PDF (contract) with electronic signature fields to a client which sends the document to its legal service for execution? The last time that I sent him one he simply passed on to its legal group but it infiltrates automated email (text pending signature) even after its Legal Department has run.

    Hey bje59649739,

    Please check that no signature field is empty in the document to be signed.

    You can send the document yet keep identification of the signer's email (under: label) for the Legal Department to get the completely signed document.

    Let me know if this helps.

  • I'm trying to create a PDF file with several signature lines in that anyone can "Sign" by using their digital signature CAC (Common Access Card) active. The goal is to have a single document that people can open, sign on a designated line and save the doc

    I'm trying to create a PDF file with several signature lines in that anyone can "Sign" by using their digital signature CAC (Common Access Card) active. The goal is to have a single document that people can open, sign on a designated line and save the document (replacing the existing document) and close. Then another person can open the same document digitally sign another area of the form, save it, and close it. So on, and so on. Is there a way to do this? At the end of the day, I would end up with a PDF file with literally hundreds of signatures to enable different ACC everywhere...

    I don't understand what the problem is. In the post of the davidr96549424 on May 8, 2015 07:58 you presented a structure of a correct document. Is the issue of the creation of this structure in a PDF file? For this, you will need an Acrobat, not reader.

    XI in Acrobat, select Tools-> forms-Edit. Click 'No' on the form fields 'detect '. In the tasks Panel that opens, click on "add new field". Select "Digital Signature" and move it to the location in the document where you want to than the appearance of the signature to be. Repeat that for signature fields as you want. Users will sign by clicking on the prepared unsigned signature field which shows the dialog box "sign. Do not forget that as TSN has noted that a digital signature applies to the entire document. The entry in the document where it is is irrelevant. Each next signature covers all previous signatures.

    Your users can also sign a document from anywhere that they want without signature fields already prepared. For this select fill & sign-> work with certificates and the type of signing you want to sign up with. A dialog box that will tell you a rectangle for the appearance of signature rises and after you draw the rectangle of the dialog 'Sign' rises.

    PDF/Acrobat doesn't have a limit on a number of signatures in a PDF document. But! Don't forget that when you open a PDF file with Acrobat/Reader signatures valid all of them and takes time (several seconds - until 10 - for every signature), so if you have several signatures of dozens of their validation open can take a long time.

    I don't know how build you your workflow so that each person signs the same PDF and saves it. Economy runs on the same computer where the PDF is stored. You'll have to decide how to allow different people to have access to the same PDF. They, of course, you may sign this only one-at-a-time PDF.

  • Digital signature of a PDF with Adobe Reader

    Hello

    Did I miss something or it just not work?

    Thanks in advance

    One thing that can cause this is a system incorrect date/time on one of the machines. If the date indicated on the machine of the reader is before the date on which the document was compatible player, it will happen.  It could be something else, like a font problem, but it's hard to say without looking at the paper.

  • The maximum number of signature in a pdf of valid by acrobat or adobe reader

    How many signarues can be valied by acrobat or adobe reader

    I found that when the number of signatures in a PDF on 254, the signature is not valid if they are valid by the other pdf reader.

    It's logical. To validate a signature seems to imply the creation of a temporary document of the signed file, so you force Acrobat to create hundreds of temporary files. As well as still holding, you have reached a strict limit on the files. The signatures are always in the whole of the file; signed with a digital signature "per page" is simply sign the entire document to hundreds of times. This confusion occurs when the irrelevant 'appearance signature' is considered to be important. It is not, and users will have to learn to ignore absolutely. I would like the forbidden appearance. To move a document based workflow page, tag each page with text and graphics required, then sign once.

    It is has never been reported before to my knowledge. The incredibly poor performance causes everyone to give up a lot earlier. Congratulations on your determination!

  • How to sign a PDF file with a certificate using Acrobat Reader DC? It works fine in Adobe Reader XI.

    Using Acrobat Reader XI I can sign a PDF document with a digital certificate. After the update to Acrobat Reader DC I can't understand how to do this. I don't see where I can sign with an image of signature mu, but how can I register with a certificate?

    Check

    In the top bar, select "Tools". Check if the list of tools in the right pane has a 'Certificate' tool If he does not appear for the 'Certificate' tool in the list of tools in the main pane (you had to scroll down to get to her. The legend below should say 'Add '. Click on it. The 'Certificate' tool is added to the list of tools frequently used in the right pane.

    Now that "the 'Certificate' tool is in the right pane, click on it." You get a new bar on the top that lists the operations that you can do with digital signatures. These are the same options you had in Acrobat XI when you clicked on filling sign & -> work with certificates.
