Query: grainy quality, very slow drying time.

I was terribly disappointed in this product which I bought for use in my Canon Pixma iP6000D printer. The image is grainy and, if you touch the photo within 5 minutes, you will leave marks. I laid anothe picture on top of one done 5 minutes earlier, and they stuck together. I have had very good luck with Canon paper.
