Any ideas on the best way to convert a scanned design from an old book cover to a crisp black and white image which will be used to recreate the original printing plate. Below is an example of a design scanned from an old cloth book cover. I need a b/w image i.e. all the gold in black and background completely white. I have struggled in Photoshop trying to change colours, adjust levels and thresholds etc. but cannot get it clean enough. Would I be better somehow redrawing it and, if so, how?
I didn't find the right solution from the Internet.
