RE: Paper negatives- Ink Selection

I think that there is something in Pictorico's base that blocks UV a little.
I use cheap OHP film made by 3M, 12 for 100 sheets A4 size. Gum exposures
for me are about 4 to 7 minutes depending on pigment. I'm keen to try the
paper Loris is using so I can print bigger than A4 at a realistic price.
Pictorico is not in my budget.

  I scanned a negative printed on this transparency material, along  
with a print made from the negative, so you can judge for yourself.   
The negative looks odd to me because the scanner filled in the clear  
parts with white instead of leaving them clear, even though I scanned  
it as film.  I guess it's been a while since I've scanned black and  
white negatives, but I thought it left the clear areas clear.  Oh  
well, the point was that the negative is very thin, but prints a full  
range of tones, or as full as gum can manage in one coat.


Also, I've thought about it some more, and looked back through my  
files, and realized that I did print greyscale negatives (all color  
inks) on this  transparency material on my new 1280 for about a year  
before I switched to colorized negatives.  Like Laura, my exposure  
times with these transparencies are about the same as my exposure  
times with oiled paper negatives, and my exposure times with  
greyscale (all color inks) on this transparency film were about the  
same as my exposure times with colorized negatives on the same  
material.   But my exposure times with Pictorico, when I used  
Pictorico,  were longer than my exposure times with oiled paper
