Hi Calverly,
Thanks for your reply, it's not the writing styles I have a problem with, it's when the original PR was obviously faded with a digital image by pushing up the contrast control and lowering the brightness ( in photoshop) often I can get a readable image.
With the micro fiche reader, some of them let you vary the stength of the light as well as slight magnification, but usually that is not enough.
Best
John
