@jedda I found the reason!!! It has to do with the QC stickers. I always buy them in a premium shop so I always get them with blue or orange sticker. I never knew they also made cheaper ones. If it comes with grey or yellow, they don't take ink very well. Blue is flawless. My current one came with orange, which seems to be new, but also no problem with bleeding! Hahaha thought you wanted to know ! Here is a good video: https://www.youtube.com/watch?v=fn0zFI5wuBU
