Trying to insert a barcode into some artwork on Illustrator CC when i try to free rotate the barcode and downsize the lines are becoming jagged? I have anti aliasing checked and the barcode is in an eps format?
Sounds like your barcode is a bitmap / raster (even if .eps, the format is capable of embedding bitmaps).
If that is the case, you can solve it by tracing the barcode first.
- LiveTrace while the barcode is still vertical
- find the preset that gives best results, check Ignore White
- rotate and say goodbye to jaggies, win.
