The problem with all those new attempts to reach the old material qualifications is that it's impossible to reproduce the same photo paper and film on another coating line.
So a lot of product specific parameters are going to be lost.

As far as MCC is concerned using a different coating line really isn´t the problem. If at all the problem lies in the precipitation and the raw ingredients but we solved most of that and the rest is beeing solved these days.
This is why it is so important that we are using the exact same precipitation vessels, controling software and run protocols.
Agfa itself has used several different coating lines for making MCC in the past years before shutdown but they alwas made the emulsions in Leverkusen and shipped them to the respective coating destination (just like we are doing now).
The problems in coating do exist, I don´t want to put them asside, but they are solvable. It is a matter of adjusting the emulsions to the parameters of the coating line and every skilled emulsionist or coating engineer will confirm that it is a question of a few more or less runs in order to get the process adapted (e.g. adjusting the viscosity of the emulsions to the speed of the line and the temperature of the stiffing section and to choose the right parameters on the controler of the drying section).
We are doing exactly this at the moment on the test coating line. If we hit it right on the spot in the first run the samples will be ready by the end of next week. If not we need to make a few more runs until the process is properly bedded in.
If anyone out there should really be in doubt about the comparability or the quality of the paper he or she is welcome to participate in the testing together with the others.
After all this is why we do all this. To show what can be done in a micro factory and to get feedback.
Except for "half-scientific" tests (e.g. if the paper harmonizes with a certain lith developer or developer and toner combination etc.) we are 100% on Agfa´s old specs acording to all of Agfa´s old standard protocols.
News:
The width of the small coater is 24 cm including coating edge. We decided to cut the samples INCLUDING the coating edge to 24x25,4 cm (X by 10 Inch) in order to make the sample confectioning easier.
The usable size will be just above 8x10 Inch because towards the edge the quality will fall off and eventually there will be just a track of white paper base left and right.
Have fun with the samples- everyone who applied sofar is counted in.
