The Blues are still without a win at home this season and Clark was relieved with the point at St Andrew's after goalkeeper Darren Randolph kept Ipswich at bay following Christophe Berra's first-half score.
For much of the game Ipswich appeared as if they were heading for only their second win of the season after Berra scored on his debut after 36 minutes.
Birmingham refused to concede defeat, though, and staged a late revival with Scotland international Chris Burke scoring a characteristic equaliser late in the second half.
It was the first goal Birmingham have scored at home this season, which in itself highlights their problems.
Clark said: "At least in the second half the players were true to themselves as individuals.
"We did not create any chances in the first half but we had a go in the second half and had a bit of luck with a deflection to give us the equaliser."
Birmingham were deeply indebted to a five star performance from their goalkeeper Randolph, who made three superb saves including a first-half effort from David McGoldrick he finger-tipped onto the post shortly after Berra's goal.
Clark paid credit to his goalkeeper for helping Birmingham to pick up a valuable point.
He said: "He (Randolph) has continued his impressive start at the club.
"The whole package with him has been excellent, coming for crosses and his distribution enabled us to try and play on the counter attack.
"He has shown everyone he is a first-class acquisition and I feel I have obtained a good package. We are absolutely delighted with him.
"The Ipswich game was frustrating. We did not show our best qualities as we were too negative.
"It was no coincidence that Chris Burke obtained the second half equaliser. He works every single day to perfect scoring such goals."
