Hey dudes, i'm having problem with having white text on black background (Illustrator). Take a look at the attachment. Both are white text, but the one on left, i think the color is like blend abit, i don't know. I tried bring to front but still the same.

Both are same type, size and styles. I tried do a test print, really something wrong. 

The box is also white color, but turn out grayish color.
