Bottom Sil Screen Text Mirrored on JLCPCB

I'm using PCAD 2006 and created a two-layer (top and bottom) board. It has about four components on the bottom and separate text (revision, date, etc...).

After uploading the gerber files to JLCPCB, it showed the components on the bottom and their reference designators correct (in PCAD 2006, I press 'F' to flip the component to the bottom, and it changes the ref des text to mirrored so I see it as a mirror image - I don't believe a way exists to view it as looking from the bottom).

I also "flipped" the text on the bottom layer for revision, date, etc... thinking that if the component ref designators showed as mirrored in PCAD, then the text needs to show as mirrored too.

This caused JLCPCB to show the bottom layer with the component ref des correct, but the text was mirrored. I went into PCAD and "flipped" it again. Now I can read it normal in PCAD, however, it still showed as mirrored on JLCPCB.

Does anyone know what I need to do so the text isn't mirrored?

open the gerbers in a gerber viewer like kicad.  check them there before sending them to fab.

PCAD bottom layer silk should look "backwards" in pcad for it to be correct on a bottom layer.

Thanks!

I was just about to provide an update before reading your reply. Seems I needed to select 'mirror' in the gerber (bottom silk) section.

I saw this before, but feared it would mirror the ref des too, so I didn't select it.

The PCBs should be arriving mid week.

From the online viewer on JLCPCB, it looked like no matter if I left the text normal or flipped it in PCAD, it showed as mirrored.

I'm just curious, why did flipping it still cause it to be mirrored, and why did selecting 'mirror' in PCAD did the ref des not change? They are on the same bottom silk layer, so I'm not sure why it chose to invert one but not the other.
