"I was a little bit nervous today, it’s a final so you have to be. Jo played great tennis so she made it quite tough for me," the Czech said.
Asked about her prospects at Roland Garros, she said: “I just hope I can take the tennis I was playing here to Paris and we’ll see.
"I think there will be a chance for me if I play this way but there’s going to be some tough opponents who are playing good tennis on clay."
Konta was broken in her opening service game before saving a set point at 5-2, but Pliskova served out the first set after the Briton failed to take advantage of the only break point she was afforded in the match at 5-3.
Pliskova missed a break point in Konta's opening service game of the second set but eventually broke the 28-year-old at 3-3 before holding serve to secure victory.
Konta remained upbeat, saying: “I’m pleased with how I’ve been progressing this year and how I’ve been improving with every match.
“To make it to a final here, this is my second biggest final after Miami, this is a big moment for me.”
Pliskova did not drop a single service game as she secured the third clay title of her career and her first in Rome in one hour 25 minutes
