The Express Image
There are those who say the wording in this passage “the express image of his person” proves Jesus is God. They say “express” means exact copy or precise.
While the definition is correct the application is not. There are two ways in which this phrase can be used, it can either be [literal] or [figurative] representation. This is outlined in great detail in the following webpage link.
See: (Hebrews 1:3 The Express Image)
(Colossians 1:15-20 – Image of the Invisible God & The Firstborn)
