I need your opinion and the title of this post says it all: unfiltered blacklight tubes or a single 1000 watt metal halide grow light? I was all about unfiltered blacklights, but I'm moving into more detailed prints with quite a bit of halftone complexity.
While I never had any troubles getting the detail I needed with a blacklight box, I recently read this article: http://www.murakamiscreen.com/docume...Comparison.pdf and now all bets are off. All that junk about cross linking, and histograms...well, I get it, but I don't know how much it will really effect me.
An old post I read had AndyMac on record as saying 1000-watt metal halide grow light is his backup (for the sun? That's O.G.) Anyway, I don't know if this still holds true.
If it's of any concern, I have really good positives, both inkjet films off an Epson 4880 and plotter-cut Rubylith. I've been exposing at school and we have a professionally-built metal halide unit with a light integrator. It's really nice (burns in 13 seconds), but I graduate in 6 weeks, so I'm looking to use those last 6 weeks in the woodshop to build something that will work post-graduation. Also, I've been using Ulano TZ, but as of today grabbed a quart of Ulano Proclaim and Proclaim-HR – mostly because our darkroom is less than 'dark' and the washout station is under fluorescent lights and anything too fast-burning gets over exposed in the washout process. When I move to my own setup I'm hoping to remove that from the equation.
