Were PIEDMONT 460 factory #42 & UZIT backs printed simultaneously ?
Steve
Your points are good ones; and, any one of them may explain the difference in the light blue vs dark blue phenomena of the P460/42 and UZIT backs.
In any event, I still feel strongly that both these T-brand backs were printed during the same ink runs. Press runs with the dark (normal) blue ink and
separate press runs with the (whatever) lighter blue ink.
Thanks Steve for your post here.
