yes. Some states have very specific requirements about how to apply the seal and signature. Any requirements would be detailed in the state laws pertaining to professional licensure.
A quick online search for Colorado's requirements led to the following.
Colorado Engineer Board Rules - See section 5.1 Sealing Requirements for Professional Engineers, especially Section 5.1.3 Signature and Date Required. It specifically states that the signature and date shall "appear through the seal" meaning that one needs to sign and date on top of the seal.
