trying to do seps for an all discharge simulated process job. On black . any tips?
and when previewing in photoshop whats do you typically set your channels opacity to?
Thank you in advance.

Of course there's no white underbase, and I like 20% or under for the top colors, of course, there is no base, so I would increase that considerably, especially on a black background.

I can't speak on the % of activator type discussions and the use of Low S mesh, but when I had been doing separation for two specific shops who do fantastic sim process discharge prints, it was very tricky to foresee the amount of opacity you might get.
For the two shops I did work with a good bit, I used 5 and10% opacity on my colors that blended together. What makes it tough, is that when you have a solid area, it was not just 10% opacity in reality. It was more like 70-90% depending on the color. Therefore, it was very hard to set up opacity across the board with just one set in all cases. You kind of hand to set it up duplicating the seps. 1 for 5-10% opacity and the other preview look for the 70-90%. Both sets contain the same sep information. It's not like plastisol and underbases.
The blend areas seem to blend quicker, easier than plastisol.

For those in the know, wouldn't you want to put down a clear discharge underbase?
If not, when would you use a clear discharge underbase?

trying to get away from having any hand at all.... normally we do discharge underbase with plastisol on top for all of our "photo" realistic jobs with much success... but i enjoy the pain of the challenge, and learning something new

our lead press op went to a simulated process seminar yesterday at ISS. they were adamant that no one was doing DC and WB seps.
which is weird, as we do them all the time.

Wait...what? Seps by Joe D. Many ys ago. Our fiend Serj may have a few examples f what no one does as well

Eric:
PLEASE tell me your press op quickly corrected them :)

who was teaching the seminar...
was it a vendor or a industry pro?

Eric:

oh he did. he also was offered a job during the class from another print shop...but we won't get into that.
industry pro. which is weird, as i've seen him do some videos of DC printing.
i won't name names as I wasn't there, but he is a shorter, stocky, bald gentleman.

I know who you're talking about --- He wears very 'loud'/designer shirts :)
my guess is this: Nobody or very few people are offering JUST seps directly designed for WB/DC printing, due to the complexities and R&D that has to be done on the print side to get things just right. -- Ie, you can't expect Dan or Scott to know that with your matsui or cci or green galaxy ink system that these 2 colors are going to blend correctly on the shirt to get perfect results out of the gate. Vs. with plastisol where you can predict that if you can make a good screen that the results are going to be perfect.
We've done some playing around with DC sim-process work and we've had to tweak to make things look great, it's certainly not as out-of-the-box easy as it is with plastisol.

Ahhh.... If its who I think it is (you forget to mention an earring? :))..... You pay him, and he will say anything you want.

Notice the date........4 color DC

ah yes! i did forget the earring and hawaiian tees/ecko tees.
Tony, quit showing off!

Its paisley and sorry Eric.

Unfortunately, much of the aqueous technology today has swept past most industry gurus and consultants. My thought is that; if you do not have hands on, boots on the ground, realtime, day to day production experience for an extended period of time, don't give advice.

Seconded!

I always take to Tony's advice. I don't pull squeegees, mix inks or any of the jobs I always did because as we grew, I had to tend to business, and let others take over the shop. So now, I like to consult with the folks running the jobs, though of course we taught them our ways, and they were allowed to go on there own as long as quality and speed is up to snuff. I still do the higher end separations, and I probably shouldn't really be doing that anymore either. If the guy running the seminar said that people aren't doing that anymore, then he's what I'd call a self described expert...

Well i can say its a learning experience.... been up on press twice , remade seps and several screens .... hopefully monday we will have it dialed in...
fortunately this particular client doesn't have a hard deadline, and just want it to be right...

I've learned a long time ago, to avoid using words or phrases like "all, everyone, none" and only use definitive words when I know for sure and even then, you could be wrong.
Always try to say, "based on my own personal experience". You may find different results. I might say, "this is what I do" or know that works for me".
I agree that I won't get you THE best seps the very first time...if I'm not at your shop on hands, and know how you do things or how your inks work as solids, blends, etc. we can sure get you a good start but water base and discharge can be a tricky beast. It's best to have a good on staff artist, ER one that is interested in his/her career as an apparel artist and separator. There are many working in orint shops that just like to design and draw and could care less about how it gets done on press. There are places in your shop for them...if you still have someone that is print savvy as well as art savvy.

Don't get me started on this guy.

does his name rhymm with Harley?

I don't think it matters "who" the person is that said this, but maybe what they were actually "trying" to say. It may have been said loosely.
It's possible that the instructor was simply saying that there are no separation "programs" that are doing water based or discharge based separations. That would be true. It can't be automated, or not well at least.
All that can be done is to set a script to blend 6,9,10 colors to represent an image. This is what's done with sep programs now with plastisol but those are a little more predictable. It's like the special affect inks. There is nothing out there that handles what needs done with the seps to handle high density inks and predicting what will happen with stacking HD screens. If you don't know, you must compensate a little on each layer stacked. The more you stack, the more you compensate.
Actually, that would be easier to add into a script per every color added then it would to predict how to handle discharge seps in an auto sep program. I mean you could add that in, but it's just a starting point.

let me just say its alot harder than i expected......several revisions an i still think it was a 80 out of 100....
