Hello

I have a lot of question about screen print .

Sorry for my orthography . i don't speak fully English

I am really new on screen print I use to use hand cut stencils (green an red ulano) to do screen print . I learn a few things in youtube about emulsions

Now i trying to do it with these Emulsion - Saatichem Textil PV .

I have a few concerns .

first is good,

I have to be on fully dark to put the emulsion.

What type of color bulb, if could use

How long i need it to let it dry

Works with plastisol and aquaprint inks


thanks

i have used a ton of different types of emulsions,from autotype, to unlano, to cromaline, several brands that were privately labeled by suppliers, the Saatichem Textil PV is now my fave. i was about to spend the extra money to switch exposure units to a metal halide version light source to help speed things up but i was talked into trying the textil pv and found that it cut my expose times down dramaticly, if i use laser film which is cloudy like vellum i can expose a white mesh in 4 mins, if i go completely clear inkjet film 2 mins in white mesh. yellow add a min to two mins two each instance. i currently use the point 1000 by workhorse for exposing which is a 1000 watt halogen bulb, not the best out there but i got a great deal on it and now using this pv emulsion spending almost 4,ooo bucks to go into a different exposure unit to gain 1 minute isnt worth it to me. ive also noticed that using the textile pv emulsion i shot a 5 color simulated process job on 155 yellow mesh screens with a frequency of 50 and this emulsion actually held those dots on that big mesh, other emulsions wouldnt hang with that and you would lose your image. i hope some of this helps, sorry for the bad spelling and all but you know how that goes,

Hey Guille, I use Murkami's Aquasol HV which (in my opinion) is THE MOST durable emulsion out there. I coat the screens in a "darkroom" that has a red light bulb for visibility. One coat on the outside - flip the screen 180º to the squeegee side and apply one more coat of emulsion. I use a small plastic scraper to remove the excess emulsion that is along the sides where the emulsion applicator over flowed a bit. I dry the screens squeegee side up in the (dust free) dark room at 80º for about ½ hour, or until I can touch the coated screen and feel that the emulsion is hard and dry.

My light table has a 1000w halogen bulb and I expose my 156 mesh screens for 5 minutes and 50 seconds which allows me to have my half tones to remain intact with sharp definition.
