I already have a call in to service and am awaiting an answer, but maybe someone here will know.

Out of no where, our screens are printing blurry. Nozzle check looks fine (on paper and emulsion), room humiditiy has not changed (if anything it's gone down) since this morning when i made about 2 dozen screens.

Yet anytime i print some new designs we just dropped into our server/hot folder, they are printing blurry. any idea as to what could have happened?

Is it blurry like low resolution?  Did a resolution setting change?

Or is it blurry like the ink edges are wicking out and getting blurry?

not that i know of. The only thing that may have changed is i made a copy of our main folder, so i could have a seperate folder for 65lpi prints. it looks like the ink is smearing some how. my phone is struggling to get a good pic.

[ericheartsu]

pic is attached now.

It's almost like the ink is going on to thick. Im' currently running on a 12+ pass, with ink thickness at 1.

ST or, Epson based?

pretty sure it's the ST/Rioch head

[screenprintguy]

Are you using D-2 ink or k?

[ericheartsu]

D-2, the latest vendor as well!

this screen is a 156, with PHU2, coated 1/2. screens were coated last night around 8pm, CST

i think this is going to end up being some sort of setting in our color print profiles. i just tried it on our "oversized" Folder/set up, and had no issues.

[screenprintguy]

Weird, mine did that with the k ink, been fine with d2. They say if you have any slight pre exposure can cause that. Have you restarted everything,  do a good 5 or so second manual cleaning by using the valve on the front of the head and the  gray 1 tab in the control software, then couple wipes

[LuckyFlyinROUSH]

Are valves positioned properly. Not getting the cleaning solution mixed with ink?

[ericheartsu]

yep yep and yep!

Our machine is in tip top shape. We had a tech out last week. they even replaced our heads for us. So two brand spanking new heads, and we've been running screens everyday since Friday.

I'm familiar with the issue with the K ink, it did it to us to. When we switched to D2, we didn't have any of the issues like we were having with K, but we started seeing some other issues. We have a new D2 as well.

At first it sounded like maybe to low of humidity. But after you said it stopped when you used your oversize folder, that does sound like something else. Is your oversize folder 65lpi or 55?.
It does sound like a rez setting or something not quite set correct ( lost in translation )

OS folder is 55lpi.

I copied the settings from our 23x31 folder, and made a secondary 23x31, so i'm wondering if that's what caused it some how? But the secondary 23x31 fold had a different hot folder, and was a 65pi, vs. the original 55lpi.

When the tech installed the unit I had him set up a 45,55,65 standard size, also in oversize.
I wasn't really watching him, but if I remember correct he did have to set some settings. What about making a new folder, not copying, and manually setting things. I have had a few odd things ( very few, like one maybe two ) with files linking weird to the color print program, so maybe its that.

My bet is on how the program is seeing the rez settings.
