SALT LAKE CITY (AP) — John Warnock, who helped invent the PDF and co-founded Adobe Systems, has died. He was 82.
Note:These steps pertain to features found in Adobe Acrobat DC, not Adobe Reader.
The Make Accessible Action Wizard in Adobe Acrobat DC will guide you through the steps of making your PDF accessible. Each step will prompt you to add accessibility information that may have been missing from your PDF. At the end of the process, Acrobat DC will run a full accessibility check of your document and will recommend further steps you can take to remediate your PDF.
Not all PDFs actually contain text in them. If your PDF is a text-based or a searchable PDF, you will be able to select text in the document. If you cannot select text in your document, you have an image-based PDF and must use OCR tools to recognize the text in your PDF.
The document title is important so that users of assistive technology can hear the name of the document when opening the file and when switching between multiple tabs within a PDF program.
Create and verify PDF accessibility
The document language determines which speech synthesizer is used by assistive technology programs.
Any images or figures that convey important information in your document must have alternate text. Alternate text is a short description of the image that will be read out loud to assistive technology users. Keep your alternate text to 1-2 sentences long.
Accessible PDFs must have tags. Paragraphs must have paragraph tags, lists must have list tags, images must have image tags, tables must have table tags etc. These tags can be accessed by assistive technologies and make it possible for AT users to jump quickly to a desired section or item in the document.
When using headings tags, your tags should follow an orderly heading sequence, such as Heading 1-Heading 2-Heading 3, not Heading 1-Heading 3-Heading 2.
If your PDF will be used as a form, make sure all of the form fields are recognized and are given an appropriate tooltip. A tooltip provides a description of the form field and is read out loud by AT users. Form fields also should have a form tag and appear in the correct order within the tags panel.
To ensure that tabular data are read logically by assistive technologies, use table header tags for column headers, row headers, or both.
You will need to manually check that the content in your PDF follows a logical practicing order. To check the practicing order, open the tags panel and arrow down. Move items up or down in the tags panel to correct problems with the practicing order.
You will need to manually check that your PDF document has sufficient color contrast. We recommend using the free Color Contrast Analyser tool, which is available for MacOS and PC. If there are contrast issues in your PDF, you will need to return to the authoring program and adjust the colors there.
NOTE:Any color contrast issues that are found will likely need be addressed in the source document (e.g., Microsoft Word). If you find color contrast issues in a PDF, and re-export the PDF, you will need to re-do all the tagging and practicing order work from the above tips.

There are times when Acrobat Reader DC fails to open a PDF file and displays the following error message – Adobe Acrobat Reader could not open PDF because it is either not a supported file type or because the file has been damaged. It is mostly seen with users who frequently convert documents to pdf by using Microsoft print to PDF. See what you can do to fix the problem, quickly.
Earlier, Acrobat products performed no checks on the extraneous bytes present before the %PDF-header. As such, it could open a PDF file as long as the %PDF-header started within the first 1024 bytes of the file. There’s however, a change in the scheme of things now. The latest updates have improved security by enforcing stricter parsing of the PDF-header. So, PDFs that do not correctly start with the ‘%PDF-‘ header are prevented from opening and you see the error message as described above.
To remove this error and open the file normally, you can modify the way the PDF is produced, making sure that no extraneous bytes appear before %PDF at the head of the file.
Launch the Run dialog box by pressing Win+R in combination.
Regedit in the empty field of the box and press Enter.
When the Registry Editor opens, navigate to the following path address –
HKCU\Software\Adobe\(product name)\(version)\ AVGeneral key
If the key does not exist, create it manually.
Switch to the right-pane.
Create a new DWORD value –
Set its value to 0.
Close and Exit the Registry Editor.

SALT LAKE CITY (AP) — John Warnock, who helped invent the PDF and co-founded Adobe Systems, has died. He was 82.
The Silicon Valley entrepreneur and computer scientist died Saturday surrounded by family after a nearly two-year battle with pancreatic cancer, the company said.
“John’s brilliance and innovations left an indelible mark on Adobe, the technology industry and the world,” Adobe said in a statement.
Warnock worked for Xerox before he and colleague Charles Geschke created a company around a rejected idea in 1982. Nearly a decade later, Warnock outlined an early version of the Portable Document Format, or PDF, transforming the way documents are exchanged.
Originally from the Salt Lake City suburb of Holladay, Warnock described himself as an average student who later flourished in mathematics.
He earned an undergraduate in math and doctorate in electrical engineering, or computer science, from the University of Utah and maintained close ties with his home state after he retired as CEO of Adobe.
Warnock was the son of a prominent local attorney but was an average student until a teacher at Olympus High School took an interest in him, he told the University of Utah’s alumni magazine, Continuum, in 2013.
“I had an amazing teacher in high school who, essentially, completely turned me around,” Warnock said. “He was really good at getting you to love mathematics, and that’s when I got into it.”
He continued to be a self-described “mediocre” student as he earned his bachelor’s degree in mathematics and philosophy, but he made a mark while working on his master’s degree.
In 1964, he solved the Jacobson radical, an abstract algebra problem that had been a mystery since it was posed eight years before. The following year he met his wife, Marva Mullins, and married her five weeks later.
After a summer spent working at a tire shop, he decided the low-paying field of academia wasn’t for him and applied to work at IBM, starting his training in computer science. He earned a doctorate at the University of Utah, where he joined a group of cutting-edge researchers working on a Department of Defense-funded precursor to the internet in the 1960s. Even then, Warnock was working on rendering images on computers.
In the late 1970s, Warnock moved to Palo Alto, California, to work for Xerox on interactive computer graphics. There, he met Geschke and went to work developing InterPress, a printing and graphics protocol that they were convinced would be the wave of the future. When Xerox balked, they decided to create their own company.
They founded Adobe in 1982 and created PostScript, a program that helped make small-scale printing feasible for the first time. The company later created the PDF, which let people create electronic versions of documents that could be preserved and sent it to other users, who could search and review them.
With that, Adobe took off, and PDF eventually replaced many paper copies in legal, business and personal communication.
Other iconic programs, such as Adobe Illustrator and Photoshop, followed before Warnock stepped down as CEO in 2000. He and Geschke remained as co-chairs of the company’s board of directors until 2017, and Warnock remained a board member until his death.
“John has been widely acknowledged as one of the greatest inventors in our generation with significant impact on how we communicate in words, images and videos,” Adobe chair and CEO Shantanu Narayen said in an email to company employees.
After his retirement, Warnock and his wife devoted more time to hobbies such as collecting rare books, many of which he’s scanned and put online at rarebookroom.org. They also collected Native American art, including moccasins, shirts, and beadwork that has toured the country in exhibitions.
Warnock is survived by his wife and their three children.

Adobe Photoshop CS5 can convert your file to a variety of file types, including a PDF, by adjusting the "Format" option in the "Save As" dialog box. Adjusting the file type to which your Photoshop project will be saved allows you to create a file that can be opened in any program with which that file type is compatible. The ability to convert Photoshop projects to the PDF format also makes it possible for viewers on other computers to see the project, even if they do not have Photoshop CS5.
Click "Start," click "All Programs," and then click "Adobe Photoshop CS5."
Click "File" at the top of the window, click "Open," and then double-click the file that you want to convert to the PDF format. If necessary, make any edits or modifications to your file.
Click "File" at the top of the window again, then click "Save As."
Click the drop-down menu to the right of "Format," click "Photoshop PDF," and then click "Save."
Click the "Save PDF" button at the bottom of the window.
Microsoft and Adobe have collaborated on "natively embedding" new Adobe Acrobat PDF technology into the Microsoft Edge browser for Windows 10 and Windows 11 systems, according to a Wednesday Microsoft announcement.
This new Adobe Acrobat PDF engine will start to appear in Edge for unmanaged Windows 10 and Windows 11 systems as early as March. It'll be replacing the current "legacy engine" that's already in the Edge browser. These unmanaged Windows users won't have an opt-out option.
Organizations overseeing managed devices won't get the new engine in March, but they can opt in to get it then, if wanted, according to Microsoft's FAQ announcement. The policy to opt into using the new engine is called "NewPDFReaderOptInEnabled."
Organizations with managed Windows 10 and Windows 11 devices will start getting their rollout of the new Adobe Acrobat PDF engine in September. They'll also have an opt-out policy option at that time. However, this September opt-out policy will just give organizations a six-month reprieve, as Microsoft intends to remove the old engine on March 31, 2024. That's also the date when the opt-out policy will expire for organizations.
The switch to the new embedded engine in Edge is being done to enhance the PDF document experience, such as adding "higher fidelity for more accurate colors and graphics, improved performance, strong security for PDF handling, and greater accessibility," Microsoft's announcement indicated. The improvements and PDF practicing capabilities don't cost users. However, users with Adobe Acrobat subscriptions can also tap an Acrobat extension in Edge that lets them perform actions such as "edit text and images, convert PDFs to other file formats, and combine files," Microsoft's FAQ indicated. Users also will be able to buy access to such "advanced features" from within the Edge browser.
The new Acrobat engine will continue to provide access to the same features as were available in the legacy engine, Microsoft assured. One coming change with the new engine will be an Adobe brand icon, which will appear "in the bottom corner" of PDFs.
Microsoft and Adobe also are working to add the new Acrobat PDF engine to the Edge browser for macOS systems. However, there's not projected date, with Microsoft saying that "we will have more to share at a later date."
Adobe's landing page describing the integration offered a broader picture than just a new Acrobat engine in the Edge browser. Adobe Acrobat and Adobe Sign (an electronic signature app) are integrated across Microsoft 365 applications, Dynamics 365 Sales and Microsoft Purview Information Protection, according to that page.
Adobe and Microsoft are long-term partners. However, it hasn't been too long since Microsoft removed the Adobe Flash video player from Windows in favor of video using HTML5, WebAssembly and WebGL technologies. Microsoft's monthly "update Tuesday" patch releases for Windows systems had often also included patches for Adobe Flash back then.
Microsoft did not describe any Edge patching details that might be associated with coming new Adobe Acrobat engine.
