Suddenly I have been getting lots of rejections for poor quality of jpeg files (when viewed at 100%) with my illustrations across a couple of agencies. I have done a little digging and it seem that they do not like the sharp/jagged lines that can be cause around the edges of objects when converted to bitmap. Has anyone else had this issue and found the best solution for sorting it out in batches...antialias etc

I still find it extremely irritating that they reject a file because of the jpeg when in reality it (on most occasions) is just for preview
