"He who marches out of step hears another drum." ~ Ken Kesey
I look forward to hearing the other side of the debate and how some are dealing with a few of the Cons you list.
Good info and perspective.I was thinking about this the other day as we were running a 600 piece two side white on blackjob that we run probably twice or more a month.We run it discharge out of habit, but I got to thinking about it and realized how muchmoney we'd be losing if we ran it plastisol.First, we would need two screens per side. Discharge is one screen per side. Add in the setupjust go.Second, the image is fairly detailed, but also has some wide open areas. That would mean230 base, and a double stroke on it. With discharge we run a 280 and single stroke it.Production time on a double stroke plastisol 230 base is 450-550 tops if we can get the ink flowingand the image isn't too large. We run this job at 700 pieces/hr plus.Plastisol would need a flash, also $$.While you do have some valid points, IE waste ink etc (white isn't a good example because we usea ton of it and probably mix a half gallon or so throughout the day, refrigerate over night and add freshthe next day) a lot of the issues you point out lean to the side of experience or not.Personally, I think design dictates ink type more than anything. Construction worker left chest small type = plastisol always.
We used to use the Murakami HVP, post expose, harden and sacrifice a virgin...
We have long since overcome all of the issues addressed above.
I really do like Sericol inks, open the bucket and go if it's wb, if it's dc add some agent and ready to roll...same shade every time, no messing around with pigs and dyes, we tried all that....not for us. one less variable to have screw with us.
