Digital BW, The Print

Paul,

I was asking due to reports that some people have 
had problems with heavy color shift after 
mounting.
Don't know which paper, ink etc. The problem was 
probably caused by too high temprature, ca100 C.
If I remember right, doesn't Kodak adhesive paper require that temprature.
That's no problem with a baryta paper but 
obviously can something happen with the inkjets.
Maybe it's a new issue for Wilhelm R to take care off ;­)

Hans
