So I was doing a few guild logo's for some people in archeage. Anyway I wanted the image on one of the logos to have the botom of it go gradient. So from black to transparent. When I do this though. The background in illustrator is white. I save it as a Jpeg and plop it in Photoshop due to the image looking better and reading better as a jpeg than a AI file. If its jpeg the image doesn't have a weird white line background. Anyway as a jpeg I use the wand tool and delete the white. But the gradient goes from black to white not black to transparent. Can anybody help?
JPEG doesn't support transparency. You can do this all day and run in circles. You need to use a format that supports transparency like PSD or TIFF. It also seems you do not understand transparency in AI - the "white" is your artboard, but it registers as non-printing/ transparent, again under the condition that you choose a suitable export format. If you understand those fundamentals, you can easily create your gradient, regardless which of the two programs you actually use.
