New Starlight
« on: March 04, 2015, 05:10:44 PM »
I just got my Starlight last week from M&R.  And I am quite happy with it thus far.  Still dialing in my emulsion times.
At the end of the day I went with M&R because thats where I got my first automatic press about a year ago and have been super happy with my local dealer.

I use aquasol + diazo for waterbased and discharge screens with a 1/1 coat (thin side of scooper)  although I have had some issues with this breaking down easily (also happen with my old UV unit) I am still looking for a good emulsion.

Using the exposure calculator I get a solid screen with 25 seconds.  (keeping in mind adding diazo adds to exposure time)

Using Saati Textil PHU (SBQ photopolymer) also 1/1 fine coat.    I get a solid exposure at 9 seconds.

And I do have to mention the Starlight unit now has a vacuum sensor that starts automatically one a certain vacuum pressure is acquired and also about 20 preset times, as well as adding a vacuum delay timer)  features which some other LED units had. 

(edited because it was moved and did not make sense in its original context)

Just ran 3000 pieces with CCI D-White using Aquasol HV and CCI HardenX (no diazo and no post exposure, just initial exposure on 7k metal halide and then apply hardener).  Finished the job wiped the screen down and there is absolutely no signs of breakdown.  Not sure if your screen was underexposed or you need a different emulsion to use with LED as I have no experience with any LED exposure units.

Maybe the Workhorse Mult-spectrum unit is the cure for these situations.

Um, "NO". Not in it's current configuration....

What you need to do is send us your information on what info you would like exposure times on and we will send you the exposure times.

Recommendations based on my shop's previous troubles:

- Give your screens an extra coat of emulsion.  We coat 2/1 round side.
- Burn for 75% longer than you are now for discharge/wb screens.  Aquasol HV has a very wide exposure latitude and with good films you can push it pretty far before it locks up.  We almost doubled our exposure time on a 10k MH unit and the image still opens beautifully.
- Use some type of reclaimable hardener, Murakami makes one called MS Hardener.  We soak our screens with it and throw them in the sun for a bit.

We use Aquasol HVP without diazo and no longer have any issues with screen breakdown, even on very long runs.  I know this doesn't pertain to the Starlight specifically, but you should see a major difference regardless of the exposure unit you are using.  We've also done test runs without the hardener and haven't seen breakdown with the longer burn times, but we use it anyways as a safeguard.
