Print technique squeegee at vertical angle?

[Dottonedan]

have any of you ever printed with the squeegee at the straight up vertical position on the auto?  Anyone?

One guy I know, does this as his typical. In other words, it's a rarity for him not to be vertical. Just curious if anyone does at any time?  When?

[Colin]

Only if I want a reallllly thin deposit of ink.

What are his variables?

Printing over a white base?

Mesh Count? - Mesh tension?

Is the squeegee sharp?

What is his chopper pressure?

Ink type and rheology?  runny Vs. thick...

Does he have to hit pantone colors?

what kind of design is he printing?
Halftones?  Fashion?  Bulletproof?

[ericheartsu]

we do, but only with smiling jack blades.

Just started printing nearly vertical, probably a 6 degree angle or so.  After attending Joe Clarks seminar at Mindseye it's made a positive difference in printing.

[Dottonedan]

This guy is printing a 156 underbase vertical. The whole prob with previous jobs is "not enough coverage" on base. I can see why.

Time for a re-edumacation seminar....

Double beveled blade?
 
We print with an 80-85 degree angle often.  Rarely do we go below 70 degrees with anything.  Using regular blades I think we'd be a little lower than 80 but I don't think we'd be below 70 very often.  I don't have any regular blades here at the moment but we use the sharp edge of smiling jacks more than the beveled side and still use a high angle so I doubt if we used regular blades that we'd change a huge amount.

We only print straight up with double beveled blade's here also and normally white inks, I would think dead ver would not give you a good ink deposit unless that's what your looking for, and then you have to use to much squeegee pressure I would think, well maybe not if you screen are super tight 30n?

[Gilligan]

Once you start adding too much pressure you aren't printing vertical any longer as the squeegee is bent over so far.

[RICK STEFANICK]

he must be printing with the edge of the blade or he couldn't get a crisp print or release.. it may seen straight up but the edge of the squeegee has to be doing the work. yes, with really tight screens you can get great results with min min angle

[jsheridan]

I rarely if ever go beyond five or seven degrees anything more the screen wasn't made right or what not we don't need crazy angles to get a good crisp ink deposit.

It's all about surface area and inertia.  Double bevels are great for this.  Minimum surface area = minimum pressure.  This basically eliminates the inks inertia to the screen allowing it to stay on top of the shirt.  The lower the SA and Inertia the less kinetic energy is needed.  The less kinetic energy = less potential energy.  In other words the press doesn't have to work so hard to print the shirt.  There are other ways to lower the SA and inertia.  Double bevels are one.

Sonny what the hell are you talking bout inertia,kinetic energy you done and went way over my head

Simple physics.  Say hi to your lovely office manager for me.

I just tried printing with a almost upright squeegee recently.  I have noticed for me, that I get a better clear out of my screen and the ink is sharp and clean on the shirt.  I will probably be printing this way from here on out.
