Choking a white base correctly?
« on: August 16, 2023, 09:53:14 AM »
When working in photoshop with a white base that has a mixture of solid areas and halftones, what's the correct way to choke it without messing with the gradations and areas that are not 100%

Thanks

Depending on the resolution, I just make the selection and Select menu, Modify, and Contract. Zoom in to get a sense of how much you need to choke and give it a shot, maybe make a duplicate file to test on and leave your original alone until you've made a decision...

I made a mistake once; I thought I was wrong about something; I wasn't

You should probably expand the top color unless you are printing with very opaque inks…
Yes, we've won our share of awards, and yes, I've tested stuff and read the scientific papers, but ultimately take everything I say with more than just a grain of salt! So if you are looking for trouble, just do as I say or even better, do something I said years ago!
