I responded privately but including some of what I wrote for the general public.?
I've been testing different transparency materials over the past few weeks to see if there is a suitable alternative to Ultra Premium OHP. So far, the answer is no.
While some material may _look_ like they can hold the ink, (in addition to another serious problem) the ink actually clumps together as it dries and appears as exaggerated grain or printer dots.
I'm getting examples together for an?article comparing different ink sets and transparency materials. I'm still testing, but I am considering adding different starter curves to allow people to use cheaper transparency films (and just explain the drawbacks backs of doing so).
Hope that helps,?
