Opportunity is missed by most people because it is dressed in overalls and looks like work. - Thomas Edison

I forgot to turn off my linearization tools, which is fine actually but I tested 20-80% and with the non-WP i was dead on for everything, with the WP films, I was 20% high on 20, 10% on 40, 7% on 60 and 5% on 80. So clearly there is more gain on these than the non-wp. This is strictly on the film, not on the print. I turned off my dot gain compensation so I could get an accurate reading and know what I was shooting for.Maybe I didn't understand the results here. Quite understandable - the way I read this is that the WP film had a lot more gain.this is probably related to the difference between the two.from what I understand:regular film is just that. Plain piece of film that takes the ink on the surface (it builds up). WP film has a coating and it uses the capillary effect to draw the ink into it. My guess is that the capillary effect caused some of the ink to spread out rather than just into the film only.This is probably film type related as my readings on the WP film are within few percent. What kind of film was it?

A pigment based ink might work better with the WP film, I am running the old dye inks.
I am using the film from Brannon at Spot Color Supply. So far it seems good.I am using a 3000 with dye ink from inksupply.comAfter the WP film sits a few days, I get a white halo effect around the image.
