I sent my logo to a sticker company for printing and they requested it as an .eps file. But they keep telling me it’s not vectorized. I changed it up a bit and lost some of the detail that made the original web version look awesome but I figured it would be okay for a sticker, but the say it’s still not a vector. I can zoom in on it and it never pixelates. I’m using a combination of text and illustrated graphics. They offered a fix it for me for a small charge but I’m trying to get my design skills up to snuff and it’s driving me crazy because I don’t know how to fix it. 

They do just stickers from vector graphics? That´s lame. It´s ok for the die cutter or paths for a laser. But the image should be anything from vector to handy photo.

Yeah, I guess. I’m just frustrated that I don’t have the knowledge to figure this out on my own and as far as YouTube tutorials, I’m not sure what to search for. There are countless videos about creating vector images and logos and converting different file types to vectors but they don’t seem to address my specific issue, which is having an image that I believe is a vector but apparently is not. 
 

Fifteen years ago I ordered stickers and flyers and cd covers that were all from jpegs and they looked like shit so I just kept increasing the size until my computer crashed and the print shop’s computer crashed too. I thought I had solved all these issues when I started using Inkscape and was able to scale things indefinitely without pixelating or crashing. 

In the end all imagery will be rasterised by the printers.

You can send them a screenshot of the opened Layers panel showing all paths and other vector objects,
