Hy ! I am new around here! My name is Andrei and since a while I discovered Inkscape. Everything was ok untill I had to do some logos for a company, logos that had transparent gradients. They needed the file as PDF, but to be editable with AI.
Well, when opened in AI, all gradients were named <Non-Native Art> and as I could say, were rasterized. Funny thing is that once I saved a PDF from Inkscape which was correct. But I was not able to repeat the process.
Can anyone give me a help with this? Thanks!
