Do you have the driver adjustment chart? It will give you that information. Just in case, I have attached it for you. Recommded copying it for future use. As you can see it will close the face causing a draw.

The A1 setting (for RH) is slightly open. Adjusting the 12 degree to 11.25 (D1) will open the face another 0.5 degrees. Conversely, going to 12.75 degrees (D4) will close the face 0.5 degrees, making the face slightly closed.
Moving to B1 or B2 doesn’t change the loft and I think that doesn’t change the open/close face.

Since I am left-handed, I have a left handed chart. Copied to my phone for easy reference. If you move up and down the loft line (vertical axis) but stay in the same column for Lie (horizontal axis) the lie would stay the same. So for your RH chart, say you move from A1 to D1, you would decrease the loft on a 12* driver to 11.25, but would this open the face at all? It would on a png 410 I played a few years back. Thanks.

Left hand and right hand works the same way, just the setting numbers are different. Vertical changes loft, horizontal changes lie.

png used to use LH and RH hosels, so the shafts were not interchangeable. Only the settings differ with Titleist. I am also LH. Since Chuck posted a RH chart, I framed my answer that way. A 12 degree can be adjusted on the vertical from 11.25 to 13.5 degrees, LH or RH.

Opening the face is how it adds loft. Closing the face is delofting the club.

That is interesting. I thought it was the opposite. I believe I got that from a png fitter several years ago that told me to add loft to close the face some what.

Think of it this way, if you take your 56 degree wedge and open the face to expose the bounce, the loft on the face is now at 60+ degrees. Chips have more spin but they come off higher. Same goes for driver/fairway adapter settings.
