I'd be interested in hearing how to keep the DC base from drying in the screen with those higher mesh counts. I'm having trouble keeping the mesh open above 225's with underbasing with DC and plastisol on top...sim process stuff. I've done a few DC base plastisol top sim process but if I go higher on the mesh counts it dries in badly.

The yield is crisper definition, resolution, and hand of course. That said once you master pure DC color, well...most never look back. Look at what The Mountain does.Danny (and Tony),So... we run our sim process jobs on 330-S mesh (and some times 270-T) mesh. From a recent post by you, Danny, it seems your runs that you're posting are somewhere in the 500-1,000 piece range? I would enjoy running DC base and plastisol top on our sim process jobs, as I even think you can get away with more colors because of possible needing less cool downs (because ink isn't on top of a plastisol white), but a few questions:(1) While on smaller runs of 500 pieces I don't see this posing an issue, my biggest concern for us on longer runs (for us, like 6k pieces), is the halftones clogging up. And, well, you won't know until WELL after you're screwed at the end of the dryer. So, what's the safeguard for this? Also, getting through 6k pieces in one day for 2 guys on 20" tall prints isn't going to happen here. So there's also the cleaning out the screen and hope you got all the small dots cleaned out aspect for the next day's run of printing. (2) Danny, have you noticed any difference in build up on the bottom of screens with a plastisol base and a dc base on your sim process jobs?(3) What about vibrance in print? At the end of a 6 color sim process job that we ran with a plastisol base, I did a test print with a DC base and the colors were a bit more more muted and the hand was not so noticeably different (so we would've lost a lot more in vibrancy than we would've gained in "hand") -- but we're also running our plastisol base through 330. Do you find your artist needs to accommodate for the top color seps when you're running DC base as opposed to plastisol base?(4) Top Colors: Do you notice a difference in speed of running the squeegee? We're running our top plastisol colors at 14"-25" per second on top of a plastisol white base. Do you find any need to slow down your squeegees to improve opacity, since you're effectively printing on the shirt itself with the DC base? (5) Base Print: What's the speed of your squeegee for your base with plastisol in comparison to that of discharge? Are you double stroking the discharge base screen like you've mentioned you do sometimes on your base with plastisol? That would kill our speed in getting the job done if we had to double stroke on our press for 6k pieces.Thanks for your input.

Really informative post Danny! I have a handful of questions, mostly general due to admiring you as a printer and wanting to learn from your experience:Are you using solid pallets or honeycomb pallets? I was wondering if you saw issues with heat related to pallet choice or if that is something you have already optimized.Do you think the buildup you experience when using a discharge base vs a plastisol base is due to the double flash and the resulting extra heat retention or something to do with the difference in the ink itself?You mention using a 225S base screen, but I believe I've seen you mention using 65lpi for most of your sim process work. I was wondering if you are using that same LPI for your base and if you have experienced any issues with the lower mesh count?Is there a particular reason you only switch blades for single stroking your base in some situations vs making that switch all the time?I know these may be simple/dumb questions. but I always look forward to your prints and would love to know more about your process. Seeing the Take er Slow print in person was mind blowing...
