Anyone an expert on screen printing positives?
I know of a couple of places that offer positive printing via mail in uk but it's quite expensive. I found another place which is considerably cheaper but am not sure if it's up to standards?
I refer to positives as being printed on "acetate" using special inks and rip software and am usually charged £18 for A1 and know they are good quality but it adds up when printing multiple layers.

I have found another place offering A1 for £6.15 and they say they are printing onto polyester film using an OCE printer and manufacturer software.
does anyone know if that sounds adequate?

I have printed good quality prints using positives printed on tracing paper but there wasn't a lot of detail or any halftones on those.

Thanks

acetate, film, transparencies etc are generally used as interchangeable terms in the world of screen printing

generally you can get a good positive using standard ink-jet inks (print as full color - not just black) on any clear media. if you have a good exposure unit you should be fine using the cheaper option quoted above

(another old trick is printing onto thin, standard paper and rubbing the paper down with mineral oil)....

the key to a detailed positive isn't necessarily in the media used - it's having a good light source and making sure there's a tight seal between the screen and positive, otherwise light get's in between the emulsion and image causing blurriness and loss of detail. invest in a vacuum unit or get some wood and weights

I've always printed my positives from layers in photoshop but I watched a few videos and everyone converts layers to spot channels. Does that make any difference?
