I know that you say you have read lots of articles about colour matching but have you read this one? It helped me when I had a similar problem with my MP6150 but I will admit I used a lot of ink and a lot of different papers before I found a combination that satisfied me. So much of the process is trial and error I'm afraid and once you have found that perfect combination of cartridge and paper suppliers you have to rigidly stick to it and hope that they don't change their manufacturing processes. I ended up by only using Canon original cartridges and Canon Photo Glossy II paper with a custom profile that I finally saved especially for the purpose. It took ages and I don't know of a shortcut to this trial and error process.
