faster emulsion?help

Posted on Wed, 28 Sep 2005 at 13:02



can someone suggest an ultrafast emulsion for plastisol

my flo light source sucks, I know, but thats where I am today...
I've tried several Kiwos, Autosol 9000,and can't seem to break the 10:00min barrier
I'm using vellum...my best results have been with Kiwo poly plus S (137 m white) around10-12 min
cant fit a faster exposure unit into the budget today so I thought I'd try to find faster Emulsion

Hi Dave,

You need something like this.

KIWO POLYCOL: SBQ-Photopolymer Direct Emulsions

POLYCOL NeXT HQ9
POLYCOL NeXT HQ9 is one of the few SBQ products available offering both water & solvent resistance. POLYCOL NeXT HQ9 is suitable for nearly every ink system and offers the advantages of all POLYCOL emulsions: one component, easy reclaiming and fast exposure times compared to diazo systems.

POLYCOL NeXT SX7
This technically advanced formulation offers terrific performance in graphic and textile applications. High resolution, sharp edge definition, and wide exposure latitude make NeXT SX7 the perfect choice for shops that print on a wide variety of substrates and utilize many different kinds of inks.

If these don’t give you a faster exposure, then you will have to invest in a better light source.

Hope this helps.
Best regards, Peter Duff.

Hi Dave,

Please describe your "flo" light source to us.

1 - Is it a stand alone commercial vacuum unit, with a light built into it, or is it a home made type exposure unit?

2 - Do you have an exposure calculator?

3 - What is your coating technique? (Do you know what your EOM is, or you’re Emulsion over mesh ratio).

4 - What is your mesh brand; thread diameter, mesh tension, and colour of your mesh.

5 - Have you tried other types of pure Photopolymers from other emulsion manufactures? (Ulano, satti, chromaline etc.?

6- does your emulsion match the spectral out put of your light source?

7 - What is your exposure distance?

As you can see I need a bit more info on your shop conditions before I can pin point you problem.

I use KIWO poly-plus SWR emulsion. On a 155 meshes, 60 micron thread diameter, white colour, and plain weave, at 24 Newton’s of tension, coated 2+3 with a coating thickness of 23 microns.
I have to expose the screen for 14 minutes with a 5000-Watt light source at a 76-inch distance. (We do a lot of large format printing, 40"x60" and up to 48"x126"}

Feel free to contact me at 1-204-632-6016 if you nee more help.

Best regards, Peter Duff.

hi Peter,
homemade unit with 18" flo lights (mostly white output)distance about 4"
I use a step calculator with halftones @ 32line
coating 2/2 with dull side of coater then scrape on shirt side,dry with shirt side down,indirect fan around 75 degrees , humidity ? not sure
mesh white 110-156 prestretched at about 24 n,
thread dia. not sure ,stencil thickness not exactly sure(really don't have the tools to measure all of these things)
the only SBQ's I have tried have been kiwo & autosol,have kind of come to the conclusion that my lights are not in the "ultraviolet" enough range of the spectrum to be fast...I can acheive a really good screen but it takes some time for a proper exposure,once a long time ago a rep gave me a sample of a really fast emulsion, like 3 min with a halogen lamp ,I just cant remember what it was,Ulano?? I've been using Kiwo polyplus s for about 10 yrs,with a 3k Amigraph,(this is a new job I am at now)..thanks for your input

Kiwo makes an excellent styrl basolum quaternary emulsion called TX5 that'll work fine for plastisol. Don't expect it to reclaim easily if you are using UV or solvent inks.

You NEED an exposure calculator to get times right, but with TX5 and a good 6000 watt metal halide lamp you can expect times around 15 seconds for a 390, about 20 seconds for a 355, about 30 seconds for a 305, 45 seconds for a 230, under a minute for a 156, and around a minute for a 110.

That's WAY under the "10 minute barrier".

There are a lot of things that affect exposure time - but you need a good light first. I use a NuArc lamp and it is very reliable. Kiwo makes the best emulsion in the business, if you TX5 or SX7 isn't fast enough for you then you need a new light.
