Does anybody know the trick on getting smooth white prints on 50/50 Navy tees.
I am printing a a 156 base ppF with a 70/90/70 high angle sharp squeegee,med pressure on my autopress then hitting again on a 110 high white ppf and I get a hairy print attached.
Zoom in and you can see the fibers of the tee in the white ink.
Thanks

Low tension screens!  My first guess and probably right. ;)

I'd check off contact and make sure you have about the thickness of a nickle between the shirt and the screen.  You can table up and press the mesh to make sure there is clearance.

I would then more to squeegee pressure.  Are you clearing the screen fully?  You might have to double stroke the print(i know people are cringing right now, but he can get the job out the door and then work on fine tuning everything).

If you have too much pressure you are driving the ink into the shirt and picking the fibers up after it prints. 

There are tons more things, but these are usually the ones that get us.

A few ideas:

- Use the lower mesh as the base, and the higher mesh as the highlight
- Double stroke the base if necessary
- Less pressure on stroke
- Roller squeegee after the base flash
- S-Mesh: 135S for bases have become our go-to here, but 150S does pretty well too
- New pallet paper / Clean pallets - This can cause a major improvement with certain fuzzy type blends

I have found with the epic quick the second stoke or excessive pressure is usually the issue. Not that u want to but you could run a first down clear and flash. then print the quick white. Base will matt out e fibers better than white. oh, be sure your running like a 70/90/70 sharp blade

I found with Epic is that it has a lot of blowing agent in it. Try another LB white or poly white.
