Stay away from smoothing screens, rollers, double squeegees, beveled squeegees, hard flooding, s-mesh, super high tension screens and high EOM emulsion. All these are band aids for something your not doing right. LHave to strongly disagree with this. They are all tools of the trade that when used correctly, compliment what you're doing right.

They only aid to cover up the problem by increasing the ability of the press. The problem with that is you dont learn your press. this only stunts how good your prints can be. Take a bad print and use these tools and it becomes an ok print. Take a great print and use them and you become an award winner.
Blowing it up further and there are tiny random holes in the top color revealing the underbase. It almost looks like its repelled the orange. Few and far between but there nonetheless. Is this an underbase issue?
best way to get past the over/under flashing is to get a M&R Red Chili D Quartz flash... it has a temperature sensor that works awesome... set the flash to 200-205 degrees (or whatever your particular ink brand and color gels at), and regardless if it's the first flash, or after things get up to temperature, you'll flash the perfect amount every time.we love ours and are getting rid of the rest of our flash units due to it.In the past, overflashing seems to have caused the most amount of troubles with prints like that for us... once we got a handle on our flashing, those little 'specs' went away.

Few and far between but there nonetheless. Is this an underbase issue?There are two big things that can cause that and a few minor. The first of the major reasons: It can be a fiber with ink on it sticking up past what the top color could cover. Second major: The top color didn't clear of ink completely. With a loupe you can find out which one it is and then deduct how to remedy the issue. When you look at it closely with the loupe, obviously if it's a "crater" type spot the top color just didn't put down ink in that spot due to a number of different reasons, perhaps a lint booger on the orange stencil or something else obstructing the ink, or simply a bad print stroke that left micro traces of un-deposited ink. You can see those spots on prints that have a very rough underbase laid down along with a high mesh count used for the top color that just doesn't deposit enough ink to cover the peaks/valleys of the rough base print. If it's a very small spot you can add a few degrees of angle to your top color and deposit slightly more ink and it will cover, or you can do things to smooth out the base print. We could chase the rabbit down this hole for hours on how to accomplish all of that but you guys look like you've got a handle on all of that and can fix that with minor changes on press most likely. It wouldn't take a drastic change in procedure or mesh count selection from what I see here, it's not a major flaw.
