Text black

I print for years already with compatible ink cartridges for gerademal 55ct the cartridge! Mitlerweile I have found that the colors have no difference from the original. Only the thick black for text printing know to slight imperfections! The original has a much deeper black and not as strong shimmers through paper. The colors and the photo black I stay still in my 55ct cartridges the thick black but I buy only original! Who do not mind (the one with the text printing) can still reach for the cheap thick cartridge!
