Whew, I am no longer seeing stripes! 
Here's a follow-up on my recent encounter with the "Venetian Blind Effect"
while making pt/pd prints from digital negatives on an Epson 3800. If you
happen to experience this strange vertical banding of
dark/light/dark/light?especially in high value areas of your prints?here's a
few things to consider:
1. Set the Paper Thickness to 6 (Pictorico Ultra Premium OHP Transparency
Film is 5.7 mil, but the default for Premium Photo Paper Glossy is 3 mil) 2.
Set the Platen Gap to Standard (instead of Auto) 3. Change the Paper Feed
Adjustment by increments of -5 until the vertical banding disappears (for
me, the magic number was -30) OK, now back to printing . . .
