emulsions

Sonny mentioned direct to screen. If anyone wants to start a thread on that, I'll jump in. Been using one about 5 years.

Does anyone here have any experience with Ulano's TLX diazo emulsion?

It is a Diazo “Dual Cure” emulsion with a light green tint, relatively fast exposure for a dual cure, easy to see for production needs and user friendly.

Similar with other features is KIWO Quantum.

Thanks Doug, its a funny story that goes along the line of your other thread about frustration and vendors not giving a poop about the buyer. I actually got the gallon of TLX from a local very very small manual printer. He would be lucky if he used a gallon in 6 months time. His vendor sold him the TLX and he thought before it arrived it would be pure not diazo. I traded him a gallon of QLT since we use roughly two gallons a month or more here.

Just goes to show how can a vendor sell someone an emulsion to someone knowing they will not use it in 2 months min and have a poor light source to start with.

If you can divide the gallon into 4 parts (if you have the containers) and sort the diazo into 4 parts - mixing as you need. You do not even have to use a scale and get it “super exact” a careful eyeball will work.

TLX and Quantum are my current dual cure favs because of the light easy to see past tint, and the slightly shorter exposure times. With a good positive you can get very good results even with low power units and it coats very nice (both).

[DouglasGrigar]

assuming equal and optimum exposure calculation, vacum PSI, coating technique, etc  the emulsion has very much a lot to do with the final stencil outcome. Then again we all have different standards.

Without a doubt, with the targeted variables removed each and every emulsion product has “features” and demands that are different from the others.

There are the five (actually six but not generally available) emulsion types in “catagories” and each of them can have specific features within that group.

Diazo alone has everything from water resistance to longevity in “main/strong” features to choose from.

After the dreaded orange finger tips from the first quart, latex gloves seem to become a natural part of this operation.
Ask me how I know.

And, as you pointed out, with a flat blade, it's easy to halve and halve again for some pretty even quarters.

[inkman996]

When he called me up disturbed that he had to mix the emulsion/diazo I explained he could divide it and mix more as needed but he really wanted a straight out of the bucket pure photo polymer, I gladly traded I love trying new emulsions and I have heard the LX series are good.

Tell us how you like it...

Oh and we want photos (emulsion stencil porn) BTW...

[inkman996]

I will, printing a 4cp with a light white underbase next week will try the new emulsion on that and see how it does.

Is TLX  same as RLX, just lighter in diazo color?

Lighter dye, faster exposure, easy set-up from the higher visibility, I believe you are correct about the relationship.

It is the visibility and faster speed that makes it more attractive for use with lower powered exposure units.

[RichardGreaves]

Yes, the raw formula for RLX & TLX are the same.

Light green TLX is 20% faster than RLX because it is easier to see through.

[inkbrigade]

We didn't care for CCI emulsions. We love aquasol hv. Great support from Allan

[Rick Roth]

We use KIWO polyplus Z on low mesh and KIWO SRX on high mesh. They have the best resolution, we have invited other companies to do side by side tests and the SRX has the best resolution.

They also both have a very wide latitude of exposure which is critical unless you are running a laboratory not a production facility. Latitude of exposure helps with different employees coating, with exposure bulbs not changed necessarily when they should be, and importantly with light meters not exactly reading the same light wavelength as exposes screens.

We use Saati or Murakami cap films for doing HD work, we haven't seen anything but those two work effectively.

[BorisB]

We use RLX exclusively. We used to do like Rick, with RLX for high and 925WR for low. It turned out we were not organized enough for two emusions. Finally I got good price for RLX, and it's near perfect.

What I want better:
-more solids: RLX has 38%.  42%-44% would be great. Which one is closest in characteristics?
-shorter exposure. We ordered 4 gal of TLX to test. It all needs to be shipped from USA. No stock of TLX in Europe   
-and of course Price:    it's always too expensive...

[squeegee]

I'm right with you on not being organized enough or care to run 2 emulsions.

A few years ago I started playing around with sensitizing pure photopolymers.

You might try Nazdar's Purecoat (IMS905, Ulano product relabeled), we add Ulano Diazo C-10D and in this combination it will be very similar to RLX (I used RLX for like 10 years), but has 48% or so solids and exposes faster.  I get a great deal on it, but buy a lot from Nazdar. 

Kiwo One Coat with the diazo is another that will emmulate a dual cure but with higher solids and faster exposure, decent price.  Many here swear by Murakami Aquasol HV as well, another pp emulsion that can be used with diazo, solids is a bit low on it my opinion though.
