Welcome Chicken Man,
There are a few on this forum that sell or can tell you where to get customized followers for this purpose.
I am working on typeset DATE as well as other information such as our brand in relief. This is done by using printer type on a follower. (lead not a good idea! I'm waiting for my Times New Roman 22pt, to arrive in nylon)
In my case, this is a requirement of our health department since we are going to be selling unwrapped cheese. All the information regarding our date of manufacture, brand, tax ID and telephone must be in relief.
The photo is of one option a friend uses, I hope to get a cleaner look but we shall see.
