I wasn't able to find a thread on this, maybe I don't know what key words to search for, so forgive me if this has been covered repeatedly.
Most of my clients want proofs before I start printing the job, which is totally understandable. Obviously, setting up specifically for a proof is kind of bonkers. So here is how I have been going about proofs, I print a color copy of the poster onto the paper stock I will be screen printing on, I also create a swatch card that has all of the different inks I will be printing with. I feel like this method is a little hodge-podgey. So I'm wondering, how do y'all do proofs? I have a big name client coming up and I don't want to come off as inexperienced or unprofessional. Thanks!
