Illustrator Opacity Mask not 100% transparent

I'm trying to apply a transparency mask to a simple rectangle. I positioned another rectangle over the original and applied a linear gradient to it (white to black). I then selected both images and applied an opacity mask, however the image doesn't go from 100% opaque to 100% transparent. The image starts at 100% opaque and fades, but only to a value much less than 100% transparent. Does anyone know how to fix this?

My initial thought is that you should check your the 2 values in your opacity mask. The white is always fine but I have found that illustrator often defaults to K which is part of the CMYK color mode. You will want to see if the black is actually in the RGB color mode. If it is not you can select RGB from the menu in the top right of palette. This should help with some of your transparency issues.

Next question. Is there a reason you are trying to apply an opacity mask to a rectangle? Illustrators gradient palette now supports transparency. Opacity masks can get real messy real quick & would personally avoid using them for simple shapes & only use them if I am trying fade off a large group of objects/illustration.

Hope this helps!
