I've only used starbrite inks and i'm pretty low on black ink..So I was thinking about going for Intenze true black ink (apparently it can be used for lining and for solid areas)...anyone ever used this? Also I've been seeing two different bottle designs for this ink...on ebay and on websites...one bottle has the blue label with white intenze font and another bottle has a yellow label with red intenze font. Both labels legit Intenze ink? or is one a copy??
