You can't, Technical Pan has been out of production for some time. Comparable emulsions are available:
Rollei ATP1.1 Advanced Technical Pan Film 35mm x 36 exp. - Single Roll Unboxed | Freestyle Photographic Supplies
ATP is best when developed in Rollei's developer and is nominally rated to ISO 32. You can shoot it at whatever you wish, of course, but your mileage may vary. Or you can simply shoot any of the available tabular-grain films. Resolution is less than Tech Pan or ATP, but still somewhat better than most of the conventional films of the past. In other words, any quality film produced today should have adequate resolution to support prints to about 16"x20" as an optical enlargement with no special technique or 12"x18" with a 4000 dpi scan.*

I did a quick survey of reviews at photozone.de before I posted my previous comment and did not find any with higher than 4800 lw/ph. For example, the best the highly-rated Sigma 35/1.4 Art could manage on the Nikon D3x was 3960 lw/ph. The above mentioned benchmark Summicron-M 50/2 on the Leica M9 had a maximum of 3265 lw/ph. The best I could find was the Zeiss Sonnar T* FE 35/2.8 on the Sony a7r at 4454 lw/ph.
I definitely stand by my statement. 4800 lw/ph (Pentax-M 50/1.7 on film) is quite competitive by current standards. It is tempting to speculate that the same lens would do somewhat less well on the best of today's FF sensors, but it would not be the fault of the lens.

BTW...I would like to see the test results where somewhat got 225 lp/mm on any medium. That translates to 10800 lw/ph on a FF sensor (225 lp * 24mm * 2). Woo! Hoo!
