Ya know... I've never - and I mean never - used an .eps or AI file printed from Flexi. I have always, without hesitation, created a .jpg or .tif file to print from. I know I'm gonna catch all kinds of flack from that, but designed correctly in AI or Corel, using Pantone colors or even the base palette colors, I have never had an issue with sizes, gradients, whatever. I do have watch clipping on un-welded letters and items like you're seeing (little white dots), but other than that it's all good. You're mileage may vary with that method.
