Hello Bulent and other Friends with a similar problem. I bought some photo paper in Dubai in bulk and pretty cheap. Using a Canon Pixma MG6470 AIO Printer I had the same problem with the Black Ink taking longer to dry. It would smudge and spoil the entire print. This Printer uses two kinds of Black ink Tanks - one Dye Black and the other Pigment Black. I am a Techie and a DIY person and a deep research took me to this conclusion:- a) Some photo papers have a thicker coating on which Ink takes longer to dry. b) Pigment Ink sits longer on paper before it dries - pigments in the Ink are some kind of very fine solid and will not enter the paper structure easily. c) Dye Inks sink into the paper and dry faster. d) Cheaper Bulk Ink from Ali Baba was no better or worse than Canon's original which is 5-times as expensive. I do refilling as DIY fun and they work OK. e) Better Photo Paper dried faster - Matte being better than Glossy - but still the Dye Black Ink took longer to dry. Experiment with quality Photo Paper. f) Bond Letter Paper - 90 to 120 GSM - dried the fastest. Not bad - good print quality. g) A Radiant Heater placed in front of the Prints made them dry almost instantly - Best Solution. Stay safe and Blessed in these Pandemic times. Bipin B.
