can anyone comment on Sportsman EX speed

[screenprintguy]

we always double stroke DC white on 230 mesh. I like the final print through the 230 vs a 156, or 180. Those take a nice single but for DC white, double strokes through 230 give a "clean edged" deep penetration with a vibrant bright finish vs a single, IMO for our set up anyways. I wouldn't see anyone, on "any" press running faster than say maybe 50-60 Doz per hour, on a 20" print, just because of the nature of the print. I can say, I look forward to the day of AC heads, no stalling mid design or on edges of a design like the air heads do when you need a slower fluent stroke. The air heads stall in motion sometimes and can affect the final print and force you to make adjustments that suck just to get through the run. I can see AC heads just gliding through anything, plus, Sportsman or others vs db, you can adjust your forward placement of your sq/fl as to where on the DB we have to go all the way forward all the time. Those little travel adjustments can save seconds which speeds up the process. Just different things I know I am keeping in mind for the future on a new machine. I doubt anyone running water based inks is running faster than 50-60 dozen an hour, just in the method's nature and the curing that it takes, I could be wrong though. The fastest that we can go with our Heat Wave is maybe 30 doze per hour on small designs where the shirt can be creativly placed on the belt. Other than that, if the image is big and has to be wide open full shirt down at a time, we go down to less than 20 doz per hour because of the time it takes to properly cure the water based inks. I see a big a&& sprint international in the near future  ------Parker, I think the Sportsman EXG is alot faster than the EX since it uses a Ballscrew with it's servo indexer, lil more money but a faster machine heres a vid of a guy running a 14 co EXG at 76 doz per hour and it looks on his controller that he can probably go faster if he really wanted to.

I run a servo/AC Sportsman 8/10 every day. Just yesterday and today I was running a full back, (bout a 16" stroke) one color at 81 doz/hour. I must admit that 70-75 doz/hour is much more comfortable, but the speed is there when we need it.


I keep chipping away at the shop bosses about the sorry state of our screen inventory, and hopefully someday they will listen. I often (almost always) have to double stroke white inks. The screens are all low tension statics, full of holes and tears, bad ghosting, pinholes, fisheyes, wet ink on the frames (and ink spots UNDER the coated emulsion), etc etc.

If we fire the bad screen guy and replace a bunch of screen stock, we could run the press at the higher speeds every day. Sigh.

Evo,

When you are just auto indexing your press (no squeegee/flooding/printing - just indexing), how many indexes do u get in 1 minute?

just as a FYI we set the press at 900 per hour plus or minus 100 depending on the shop.

I haven't busted out the stop watch for an exact per-minute index timing, but that sounds about right. Dry indexing, it shows 83 doz/hour on the counter, so almost 1k per hour.

At a running speed, one color, I think we calculated about 3.7 seconds per impression, so about 16/minute. Then you have to calculate the "Gildan Factor" (lint balls, loose threads, stains, bad seams, etc) and you're probably closer to 12/minute.
