Chromolithographs - any identification tips?

[phoenixantiques-petworth]

This is a general question regarding chromolithographic printing, (NOT chromes) Does anyone know a sure fire way of telling wether it is a chromolithograph or not? I am aware that usual printing processes leave a uniform pattern of dots usually predominantly black and that generally chromos have no dots. Occassionally I get a card that has variable sized random dots, with no black dots, and on the reverse has been stated chromolithograph, which has led me to think that other cards I have may also be, although not stated as such. Is there an accurate definitive way of identifying them?. Thanks all Sara

Sara, I'll ask my hub when he gets home - he worked in the printing & graphic arts business for many many years. Diane

I am guessing that everyone is stumped on this one then! Sara

Thankyou thankyou thankyou! Those are exactly the dots I was looking at. I had looked at several websites that had chromolithographs listed, but hadn't found one with a zoom! Now I know I haven't mis represented a card I sold recently- and I can get on with listing some I had held back! Cheers Sara
