hi guys, I'm brand new to this business

I've started 2 months ago to create vectors and I have a problem , maybe can help me.
I'm working in Inkscape and save my vector file as svg file then I export it as a raster file then save it in eps format. problem is that my eps file doesn't look right in preview, problems of opacity. Anything I can do in Inkscape to save it right , in order to look nice like the svg file.
Thanks
