help shooting rollei ATO 2.1 lith film

[lishii]

Hi everyone,

I am a newbie trying to make 4x5 negatives for graphic arts purposes with rollei ato 2.1 previously known as genius print film.
I am using a speed graphic.

My trials today came out very low contrast and almost washed out of tone completely.

I used:
flood lights 24w (claimed to be equivalent to 120w)
Ilford pq to develop under safe light
Development for 5min
Jobo tank with CPE2 and reel
Used f5.6 and 6 sec with iso 25 as suggested by the light meter (tried a stop up and down too)
The original target consists of bold black text and lines

Can anyone see any obious faults in what i am doing?
Thank you in advance.

I can't help you directly, as I've never been able to find rollei ortho-lith film. HOWSOMEVER, I did used to use Arista edulith (or whatever they called it). I shot it at asa 12, and developed it in Dectol 1-24 for about 10 minutes (developed by inspection under a red safety lite) They looked thin, but printed fine.
