Hi, we work with xml content in a CMS. For illustrations, we use the SVG file format, and any raster content is embedded. Sometimes, the embedded raster images receive edge lines when the PDF is rendered. The lines are 1) often only on some of the edges, 2) most often only visible on screen and not in print, and 3) only visible with certain zoom factors. Does anyone have any explanation or solution?
The PDF is not created in Illustrator. The SVG illustrations (with or without embedded raster content) are imported into the Astoria CMS, referenced into DITA XML files, and then the assembled books are used for rendering PDF through applications in the CMS.
