Fenrir--you are so right. When compared side by side, there is a noticeable difference in the darkness of the black text printed in single-sided and duplex modes. My apologies.
I ran some more tests to see the differences in the "show through" in single-sided black pigment, duplex black, and single-sided black dye on plain paper. (This last one is accomplished by specifying photo paper but actually printing on plain paper.) The duplex had the least show through and the other two were slightly but noticeably worse.
I splashed some water on all three samples and the only one that ran appreciably was the photo black but the "show through" was terrible on all three samples with the photo black being the worse. So the final conclusion is that even though the pigment ink doesn't run when it gets wet, it does cause the ink to bleed right through the paper which would ruin any double-sided printing.
Canon's logic makes sense. Adding dye ink to the black in duplex mode does not compromise the printout from the standpoint of water fastness.
I appreciate your enlightening me on this matter, many thanks.
