When you export in eps 10 the new free form gradient becomes a raster, so it is not acceptable for microstock.
To see if you have rasters in you eps file you have just to open the "link" window. If the file contains rasters they will appear there.
Personally I don't like the way CC2019 manage the gradients. I had some problems, like linear gradients becoming radial gradients after saving and reopening the files.
I also find that it has became more difficult to edit and move the radial gradient in CC 2019.
Two hours ago I have uninstalled CC2019
I am so much more happy with CC2018!
