How do NPC/IFC differ from NPHC on the subject of "Perps"?

^^ I think the whole putting lettings on event shirts is always a problem anyways. I've seen tons of shirts that come out with mistakes For example, I've seen letters for "Theta Mu" instead of Phi Mu, "Omicron Delta" instead of Omega Delta, "Epsilon Kappa" instead of Sigma Kappa, "Alpha Chi Alpha" instead of Lambda Chi Alpha, and "Alpha Zeta Delta" instead of Alpha Xi Delta (WHICH IS WHY AXiDs SHOULD NEVER WRITE OUT AZD!!!!!//endrant)
