Thanks for the input, guys.
I though I might be barking up the wrong tree as I figured this wouldn't be a tool most textile shops would utilize, but I was hoping someone has encountered this before and found a better solution than myself. I will definitely trial this is the not too distant feature and report back. Call me a glutton for punishment, but I actually enjoy trapping and find it relatively zen, but it's simply coming down to time spent and throughput.
I did check out Astute on your recommendation as I was not previously familiar and in my brief search, it doesn't look like they offer anything in regards to trapping. Tons of other cool plug-ins though, a couple of which I may revisit. Speaking of Illustrator plug-ins, there is a product made by Esko called Power Trapper that I've previously played with. It's marketed more towards the packaging and offset industries, but it offered a ton of control and at the end of the day, trapped cleaner than I would in a fraction of the time. I initially wrote it off as it's an Illustrator plug-in and we deal with a large percentage of raster files (which is why I was keen on an in-rip solution), but it is supposed to have the ability trap pixel image data, so after you mentioned Astute it clicked that it may be able to trap placed channel seps. I'm going to backtrack and take another look.
Prince, again, I appreciate the input. I'm generally on the same page with you and roll basic art into our print pricing and only bill separately if something outside of the norm is necessary. If I can't find a suitable software solution, this may come down to a lesson for myself in setting better client expectations in regards to cost / vs quality and learning to walk the line between letting go a bit and giving the client what was billed for which is something I could be better at.
