Numbering in X4

Looking for suggestions to speed up my numbering of tickets... etc... I use Jeff older version of "number generator" a true lifesaver, but here is where the problem arises... Sometimes the artwork comes from outside of our shop... PDF's or bitmaps, or something converted from adobe.. As long as the artwork is created in Corel the numbering process is quite speedy... but if it is any of the above mentioned file types, it take forever (hours) to number them.... Time is money and some of the artwork is not such that I can reproduce it in a short period of time....

 

Anyone??? Any comments??  Please!!!!
