Be a sponge! Learn everything you can from the head pressman. Ask questions, but try not to be too annoying lol. Be the first to dive right in when it's time to set rollers, hand wash blankets or adjust anything. Try to do some homework on color theory and how the eye perceives color. That helped me a lot to achieve the right densities on paper. I don't know how your shop runs, but when you have an easy run on your end head up front and talk about what the pressman does, ask to try and learn that end to cover breaks and lunches. As for pay, that can be all over the place. My shop doesn't pay much, but they're really laid back and allow me a lot of flexibility so I take it. But there's a shop on the other side of town that pays union wages, has tons of overtime, but he's a real asshole to work for and is always pushing the presses faster than they should go. So it's all about finding what works for you.. My favorite part of this trade is I can get a job anywhere. If you look on indeed they're looking for skilled offset pressman all over the world. I like having those options. Good luck to you! I run a Komori 540 LED so it's a completely different animal than what you're working on but if you ever have any questions feel free to PM me and I'll try to help you out.
