How should I trace/vectorize my logo?
First of all I would like to say that I'm new to AI and PS, therefore there's probably lots of things I'm not doing right. I am using CS5 version.
I have a logo that is mainly black and white, but because of the grays, I couldn't trace it automatically. So, instead, I made the path with the pen tool. The problem is that now I have the path separated from the original image instead of what I really want. Which is the original logo with the path so I can have everything that is white transparent.
I also tried in PS to change the white to other colour (so then I could easily change it to transparent), but I couldn't because some grays also change.
What is the best way to trace/ vectorize my logo?
This is the logo I got
Never assume the logo file you are given by any client is the "best" they have. This is especially true if the file is a raster image. If the client does not provide a vector version of their logo, the chances that there are higher quality raster images on the web are generally pretty good.
In this case, a quick google reverse image search finds a much larger version of those logos.....
Using Illustrator's Image trace on that larger version yields much better results.
This would still require some minor clean up, but it would circumvent the need to redraw most parts.
While redrawing will almost always provide the best results, in some cases tracing a large raster image can be sufficient depending upon your needs.
