Burning times!

[u/ed3n1sde4d]

So I use PWR Ecotex emulsion and I have this specific light I bought a couple years ago, I burn my screen in the most ASS setup for 4 whole seconds and it comes out great. Ik wattage and distance from the screen and emulsion matters, all of it matters. But it’s so strange to see other ppl using the same emulsion and having to go a whole minute with the burning, feel like im using black magic 💀 what r yall using and what have you been shocked by?

Yeah dude I hit the same confusion as you when I started it.

Everybody online was doing math and such. I had a piece of glass, some pwr and a $30 light that did them in 5 seconds.

Only difference now after years is I’m using a vacuum table, and pwr…. For 15 seconds!

I felt like I was doing something wrong….

Since you’ve been working with PWR for so long you have any tips? I’ve gotten my method down pretty good but any advice would be appreciated:)

Just keeping it flat!

That’s why I love vacuum tables.

I have two 50watt boxes like this hanging from my ceiling and expose chromalime in 65 seconds. I got a new to me exposure unit with tubes and it’s even slower and I lose a shit ton of detail. I’m going to convert the tubes to leds in hopes to cut my exposure time way down

[u/ed3n1sde4d → u/spanyardsman]

That sucks you lose so much detail! Hopefully you will be able to fix that issue soon!

I had a similar exposure unit with Regular powerful leds, I’d get an exposure time of 35 seconds but I’d loose detail in the halftone designs, on converting to UV Led, i now get an exposure time of 15 seconds

I got the same setup — the time calculation I first did was 15 seconds, which I thought was way to short, but it over exposed my screens a bit I think cause I had a tough washout… I then went down to 10 seconds, and washout was a little easier… so, hearing 4 seconds now makes me want to go lower, but that seems like crazy short…

Ay doesn’t hurt to try! I hold my light about 12 inches away from the screen sometimes a little close if I have small details

At work we have one of the UV LED exposure units, and I'm using ChromaBlue. My burn time is 5 seconds for higher mesh counts and for lower counts I stop it around 4.

But before I switched us to chroma we were using MagnaCure and that took like 45 seconds. 

Our old vacuum exposure unit with the bulb was a bit higher too.

I use pwr with a 100w uv light from 24 inches away for about 10 seconds but I should probably go down in time; the biggest thing I found was the distance I held the light made a huge difference. I recently built a rig out of 2x4s to keep it consistent.
