Title: Produces mottled prints with Canon Pixma printers
Review: I own a high end Canon Pixma Pro 9000 photo printer. I bought a bunch of HP Premium photo paper because it was 2 for 1. Big mistake. The prints had a mottled pattern which was quite ugly. I thought my printer must have clogged jets because the print quality was so low. I cleaned my print heads and tested the alignment, but I kept getting same lousy quality. So I got on the phone with Canon tech support which immediately suspected the HP paper (apparently HP papers are a known problem). They had me print the same photo on Kodak paper I also happened to have on hand and it was beautiful. The Canon tech support person told me that HP, unlike most of the other manufacturers use a different process with the result the paper surface will swell as the ink is applied to it causing image problems. I think the problem occurs with ink formulations which have water in them, but not 100% sure.No more HP paper for me.
Is the review positive or negative?
