So what's better? I'm sure it's all about the artist and user, but I wanted some input on pros and cons with vellum and with clear transparencies. Also, is it obvious to assume that if I'm burning with vellum that I would need a longer burn time or stronger light?
well, I'm currently building my exposure box, but in the meantime I have this old kit that includes a 1,250 watt bulb inside a 10" aluminum fixture. I also have access to laser printers that print up to 11X17 but my Canon 9900 inkjet prints 13X19. You're right about the cost thing. I only have a few bucks and this pimento loaf sandwich to my name.
the Silver scribbles I printed on my last poster were done on tracing paper with one of those pentel fat black graffiti markers. I just let it sit 30 seconds longer in my exposure unit and viola perfect screen. Nothing was lost, at least I don't think so, it was scribbles.
i use vellum cuz i'm poor
i also get a nice clean solid black image. with films i never get a solid opaque black image its always kinda blue and transparent ... i also dont use RIP or anything like that just scan into photoshop and print it out on my printer
