In a print composed of three rows of parts, the center row is sticking to the bottom of the resin tray instead of the the print plate. I have tried the print five times with similar results.

These pictures include the best and worst results:

best case: most of print on plate worst case: most of print on FEP sheet

Any ideas as to cause? Should I clean the transparent sheet at the bottom of the resin tray in any special way?

I found a great video providing solutions, and I am trying them one by one, UN-STUCK your 3D Prints, and keep prints from sticking. (REAL QUICK).

I am narrowing it down to the resin, or the printer/resin combination. The printer is a Sain Smart Kumitsu KL9, the resin is the Elegoo 3D Rapid Resin, notably in Black

In my experience, when I had the same issue happening it was because my first layers exposure time what too short.

I was experimenting with bottom exposure time (in order to reduce the elephant foot) and sometimes, with very low exposure's time, I had failed prints that didn't even adhere to the print plate and remained stuck to the FEP (exactly as it happened to you).

Try increasing the bottom exposure time and check the exposure times your resin's manufacturer is providing.
