Title: Pressure marks on Navy Sweats
Post by: Logoman on August 30, 2012, 08:04:16 AM: Anyone ever had this problem? I printed 60-70 Navy Sweats and there is a square box around the image. It is not ink or anything you can knock out but from the pressure of the squeegee. Now they want me to replace them.

people will bitch about anything.

Post by: mk162 on August 30, 2012, 09:05:12 AM: yes, it should have, i can see why they would be pissed about that.

I would try steaming them.

Hi Sam,
Got my diamondback rolling, awesome machine!
Yesterday I printed some skorts (skirts with shorts in them). Just printed a 1-color PFP. I used sleeve pallets and had pressure marks as well. I took down my pressure super low, but maybe too long of a flash. Had it at like 8 seconds I believe. Is that my problem?
Thanks!

A square blade will do that?

Post by: Frog on August 30, 2012, 02:36:25 PM: I think that Tony was referring to rounding the corners of the blade, but also, a blade shorter than the width of the board will help as well.

Post by: tonypep on August 30, 2012, 02:55:45 PM: Thats right Andy thanks for clarifying. I always recommend buying a cheap bench grinder for this. I f've found that those clever little clippers don't hold up and are more expensive than they are worth.

Yeah, that's what I figured as well. Too long of a flash. Thanks!

Didn't think of it. I'll try this as well! My pallets are all spanking new with crisp sharp edges!
Thanks!
