what does it mean when a bill is engrossed

Engrossment is the formal reprinting of a bill in the form upon which the chamber will vote final passage. When either house orders the third reading of a bill, it simultaneously orders the engrossment of the bill. Engrossed bills are official copies of the bill that reflect all amendments made in the house of its origin. Engrossed bills are prepared by staff in the Office of the Clerk of the House and the Office of the Secretary of the Senate, and they are required to be examined by the Clerk of the House or Secretary of the Senate to attest to the accuracy of the engrossed text by signing the measures. Engrossed bills are usually printed on blue paper in the House and white paper in the Senate. When a bill is engrossed, it means that it has been formally reprinted in its final form and is ready for a final vote in the chamber.
