Digital BW, The Print

I just spent the last 2 days trying to get a 13"x19" B&W print on 
these two papers with an Epson 2400.  Here is what I ran into.

The Museo Silver Rag has a vertical scratch running the length of 
the paper that is barely visible to the naked eye om the unp[rinted 
sheet but takes ink differently than the regular surface and is 
quite visible on the printed image.  It seems to be on every sheet 
in the 20 sheet box - lot X56792701.

The Innova had several sheets with surface coating overlaps that 
were readily apparant to the naked eye.  I also have has 
some "pinhole" problems with this paper where the ink flakes off the 
paper in small dots about 1/32" diameter.  Only had 2 or 3 dots per 
sheet.  The paper was brushed with an antistatic brush followed by a 
shot of clean compressed air from a can to remove any particles on 
the surface.  The vertical scratches were not observed with the 
Innova paper. The Innova F Type Gloss Black Max Paper was 17"x22" 
which I cut down to 13"x19" and had lot number 18852 29005 from the 
bar code on the package.

It seems to me that Museo and Innova need to strengthen their QA 
program.  I recall very few paper flaws from the old darkrooom days 
over the last 20 years.  I didn't have any problems with these 2 
papers in the 8.5" x11" sizes, only the larger sheet sizes used in 
this print session.  Has anyone else ran into similiar problems with 
defects in paper coatings? 

Cheers,
