Even with a catch basket, aren't you guys getting the faces of prints stuck to eachother? I made a small catch "box" if you will and ours are still getting stuck to eachother.
That can be a function of your ink / profile. I use Triangle inx that seem to dry
faster than eco-sol and profile in house to control the ink limits while still getting
great color. Also have a small (8") fan blowing across the vinyl out of the printer
to aid drying.
A custom built profile is better than tweaking canned ones of course, If you
are using Roland spot color replacement, I think the rip does not use the
profile. In any case if it is tacky for over a few minutes, something is drastically
wrong.
