CF vs CB Carbonless...

We had a rush order that is White CB, White CFB and White CF. We don't have enough CF on hand and my thought was that we could just turn over the CB and it should pad to the CFB just fine.
But then why would they sell CF and CB if they are the same?

They sell 2 part pre-collated straight and reverse and all you have to do is move 1 sheet top to bottom to change to the other. It's all about packaging description and knowing how to load it in your machine.

I just wasn't sure if the coatings were unique or not and we didn't have time to order. They needed it today. Apparently they are unique so we are going to have to uncollate some 2-part and use that.

The back of the CB sheet is coated with micro-encapsulated dye or ink. When pressure is applied (e.g., writing or printing), the dye capsules rupture, transferring the image to the sheet below.
The CF sheet has clay on its front surface, which reacts with the dye from the CB or CFB above to create a permanent mark. It is typically the bottommost sheet in a set.

CB transfers information downward via its coated back. CF receives information via its clay-coated front. They are not interchangeable because CB cannot react with itself—it requires CF's clay coating for image transfer. Similarly, CF cannot transfer information upward without a CB or CFB layer above it

We ended up using CFB for the top and middle sheet and all seemed to work well.

Or, to keep things simple, you have a male and female side of the carbonless paper reaction process. That's the way I always explain it.
