Just wondering if there is a specific reason for the coloring in emulsion. I have been using a blue emulsion (chromablue) for a couple years and just got a sample of a pink emulsion (Aquasol HVP) and it burned nicely. I know the Aquasol has a bit lower solids content, but is the color anything more than just preference for registering your designs?

That’s a good question. I use aquasol HV (blue) it is the best I have found. I know it comes in pink but I have never used it. I personally would not use a pink emulsion. Now if they came out with a lime green emulsion I may try that.

why would you not use a pink emulsion?
-
There are some emulsions that come in CL versions but the primary reason emulsion companies color code their emulsion beyond registration is............anyone?
Hint: think of squeegees.
-
I was wondering the same thing. Why not use pink?
You can get emulsion without the dye if you want a clear. Its just a bitch to see pinholes.

Viscosity?

Good answer but not quite right.
-
Solids content? I suppose they're about the same thing.
As for squeegee's being color coded, I wish all the manufacturers would adopt one system.
-
If you use a variety of emulsions, and have choices of colors, it's nice to see quickly what blues you have, (Photopolymer), and pink (dual cure) or water reistant purple.
The names, of types and colors of the emulsions represented in the drama you have just watched are fictitious. ;D
-
Thats correct Andy but I knew you knew already. It's primarily for identification. Same with squeegee materials. It's quicker to ask for a red squeegee (squeegee rojo) or blue emulsion than explain the physical properties of durometer or emulsion characteristics especially in large shops with high turnover. Those discussions should, however, happen eventually of course.

why would you not use a pink emulsion?
The color pink represents compassion, nurturing and love. It relates to unconditional love and understanding, and the giving and receiving of nurturing. There is no place in a screen printing shop for that crap. The real reason is everything in my shop is blue or cool tones and having bright A$$ pink would bother me. Remember I was a graphic designer for Corporate image for many years so inconsistencies in image bother me. I know it’s an anal thing. Another reason is if I used that bright pink/red stuff my dark room washout booth would look like a murder scene.

My favorite emulsion is a mid priced house brand called Davis "Purple" but man it sucks for registering jobs, much prefer pink. Pink seems to always be the more expensive stuff for whatever reason and green being crappy cheap stuff. There should be a yellow. Always wondered if clear and food coloring could work?

I only use pink Ulano QTX, wish I could find a blue that was as good and similar in price. Chromo blue is WAAAYYY to expensive.
-
I haven't used or priced it recently, but the blue one I used to use (and love), Chromaline PL, was my choice over QTX, and always similarly priced (High! Kissing a bill if I remember correctly)
-
I only pay $62 for QTX, that blue you mention is like $97 a gallon.

You could try Ulano SP 1211 or whatever they call it. Developed for Russell as a replacement for QTX. Purple in color and a good emulsion.
FYI Xenon has a QTX like emulsion foe around$50 per gallon. Called Plastofast. ;)
-
Yep, like I said, although for years I justified a little extra money for a good emulsion that never let me down, it climbed higher and higher. Right now I'm happy with a red one from CCI, Prochem PFX-HV. It's priced closer to QTX, if I remember correctly.

That has to be hot to handle, lol.

I use kiwo poly plus s, a fantastic emulsion imo. Though I am pretty sure that it doesn't work for plastisol or waterbased. They do offer more expensive options in the poly plus line that will do everything, including ceramics. Anyhow, they offer it undyed (clear) and dyed (green when wet and blue on a white mesh when exposed. I understand that dyed emulsion is generally to avoid incidental light ruining the exposure, but the clear poly plus seems strange to me. The type of stencil that the user is likely to make is high detail. It could be that they realize that most of their users will be using dyed mesh already and that might take care of the light bounce?
I have another emulsion question, some of the emulsions I have tried in the past claim to be freezable. Does that mean what I think it does? Why would you freeze an emulsion?
-
I had a salesman lose (or at least not get) my business. He saw I had pink emulsion and he didn't, so he didn't even try to sell me anything he had. I could give a rat's a$$ what color an emulsion is. I care how it performs. Color for registration issues will go away if you have and use a good pre registration system. (We do. We don't even have registration marks on our screens.)

Chromablue $59 - Wild Side North

some people are very particular about emulsion color, it's really funny. I prefer pink, it's what I've always gone back to.

I got a spiel from a salesman this spring that was the opposite of this--that the new Ulano Orange they were carrying was dyed to reduce halation on white mesh. So what's the blue dye do? I asked like an A$$. Wasn't any better than the Plus S (I also run)
IMO, you need dyed mesh and dyed emulsion to get the best exposures--although I've been wrong before. :)
I'd be curious as to whether or not there's a difference between the reduction in light scatter between colors--I mean, they dye mesh yellow or orange--the complement of the blue light you're trying to keep under control. Why isn't yellow/orange the standard for emulsion color? I didn't think the orange colored emulsion was any harder to register--even on orange mesh.

I LOVE salesmen.
"yes we can do that"... but I didn't even ask yet. LOL
I had a few platforms in the gulf lose internet connection and when I called the head of tech support that morning he answered the phone "yes, we know we have a problem... we don't know what it is but we are working on it." I then went in the building to talk to the bosses to let them know what was up and they were like "Yeah, Steve was just in here, he said we would be back up in an hour".
LOL... the techs don't even know what the problem is but the sales guy already promised it to be fixed in the hour.
