Wet does seem to be a problem. As is evidenced by the heavy side to side streaks shown in the pics. Mine had a problem also in drying as I was not completely aware that some of the ink was still wet but found out quickly when i removed the test from my scanner I had some smudged spots.
This now being known I tried another a few days later as my printer has more than one ink setting.. One is normal, another best, one called maximum DPI and one called fastdraft. The fastdraft prints the fastest and the colors are lighter so I am thinking less ink being delivered.
The result is shown here in this pic.

As shown the side to side mess is much less, yet still in the same place as before but now the whole thing has less appeal and zing because the color saturation just isin't there.

All this reminds me of another plus for Doculam. It takes Sharpie permanant ink just fine and it comes in many colors including silver metallic. Seems they quit making the Gold metallic Sharpie.[] The utra fine Sharpie in black does great panel lines and other details.
