Hi
Check to see if information below helps you.
Follow these steps to configure Word to perform a better image quality:
1.Display the Word Options dialog box. (Click the File tab of the ribbon and then click Options.)
2.Click Advanced at the left side of the dialog box.
3.Scroll down until you see the Image Size and Quality section.
4.Make sure the Set Default Target Output control is set to 220 ppi.
5.Click OK.
When you perform these steps, Word converts any high-resolution images to the resolution you specified in step 4. If 220 dpi is not sufficiently high-res for your needs, then you should (in step 4) click the Do Not Compress Images check box. When set, this
causes Word to ignore whatever you have specified in the Set Default Target Output control and, instead, include any pasted images at their original resolution. This results in the highest resolution (provided your images are higher resolution than 220 dpi),
but it also results in the largest document file sizes.
Finally, whatever format you decide upon for your graphics, you'll want to use the Picture tool on the Insert tab of the ribbon to actually insert the image into your document. If you paste the image instead of inserting it, Word may convert the image to
a bitmap version that is not the greatest for some purposes.
