PDF files contain both text and pictures and retain the same formatting on multiple different readers. PDF format requires a special reader, available for free from Adobe and many other software publishers, but doesn't require the recipient to use the same software as the file creator. Transforming word processor documents and other files into PDF documents makes them simpler to distribute. However, some PDFs come out blurry or low in quality, even when the source file looks fine.

Human resources management has a major role in ti knowledge management. Human resources can create an effective knowledge sharing culture within and throughout an organization through upholding transparent communication and creation of knowledge base within the company. Create PDFs out of almost anything. With Acrobat DC, it’s easy to turn practically anything into a high-quality PDF that looks great on any screen. You can even separate and merge documents in a snap.

Low Original Resolution

If you start with a low-resolution image or other file, the resulting PDF may look blurry or pixelated, especially if printed out. PDF converters can't make your finished document look any clearer than the original. Use files with resolutions of at least 72 dots per inch for Web display and 200 to 300 dpi for printing. Enlarging small images can also increase blurriness.

Incorrect Settings

Even if you start with good quality images and text, the final PDF file may look blurry. If this happens, check your output settings. Some PDF converters default to a relatively low resolution for output, resulting in a fuzzy-looking result. Use the same resolutions you would for originals, and don't choose images made at screen resolution for a document you intend to print. The file may look good on your monitor but will always do poorly on the page.

Software Incompatibility

Sometimes, you need third-party software to convert your file to PDF. For instance, Microsoft Word doesn't include native PDF conversion. Visio objects and some graphics embedded in Word documents may not combine well with third-party PDF converters, producing blurry charts and illustrations. Try converting the problem object into a format the third-party software can handle, such as a JPG, or use a different conversion program to produce clean results.

Zoom Problems

Some PDF viewers produce slight text or image blurs when they display documents at less than 100 percent display size. Resolve the blurriness by viewing at the actual resolution. Zoom problems can also end up embedded in the document. This most often happens with Web resolution images, such as screen captures. Use only screen captures at 100 percent of the original resolution. Crop them instead of resizing and avoid using JPG compression, which can add blurriness or other viewing artifacts.
