Quite the contrarian, huh? Hand painting signs isn't even remotely similar to digitally printing signs. Hand laminating and machine laminating are the exact same processes, just done differently.
You clearly didn't read my post or you're being intentionally obtuse and confrontational (or maybe just didn't understand my point).
You're welcome to your opinion, but if you think hand finishing skills aren't worth knowing, you and I have drastically different opinions. There will eventually be a situation in which you need something laminated and for whatever reason you don't have access to a laminator. It's like saying a carpenter doesn't need to know how to use a hammer because nail guns exist. It's a ridiculous statement.
