The mark consists of The mark Knock it Off has a capital K that looks like a bubble font and a capital N in a different font that looks comic like. Some of the words in "knock" is lower case so "ock" is lowercase in the same font as the N in "nock." The word "it" is lowercase with the "i" having a heart for the top of the "i" instead of a regular lowercase i. In the word "Off" the O is the same font as the 'K" thats uppercase in "knock" and is a bubble like font too, the letters "ff" is lowercase in the same font as the rest of the letters in the word that's a comic like font.. the only two letters with a different font is the K and the O which look like bubble letters while the rest of the letters in the mark are comic like letters. The K and O are the biggest size font letters and look more like bubble letters while the rest of the letters "nock it ff" are all the same font size and same font. It's meant to look like KO which is why the K and O are bigger that the rest of the word in a different font. again, the only other letter other than the K in the beginning of "knock" and O in the beginning of "off" that is uppercase is the N that comes after the beginning uppercase K in knock, it's just a different font and size because the K and O in the word are meant to stand out the most in the whole word.
