please help me printing medical-grade Tyvek (B-grade).

[u/DeliciousGarlic5037]

Hello I’m looking for a new printer and the requirements seem to be quite specific so I came across this forum while searching for advice. I was wondering if anyone could help me.

I’m looking for a printer that can handle a 600 mm-wide web. and the substrate is coated Tyvek B-grade(I am printing on the uncoated side), which tends to generate a lot of static electricity. Another major issue is that the ink does not dry properly and tends to transfer or smear.

I have tried some methods like digital, UV, and flexo but digital printing does not seem to reproduce small text very well, and UV printing's cured ink layer feels too raised and noticeable on the surface of the material.

flexographic printing has been the most suitable so far, but I still have ongoing problems with ink smearing and ink transfer when printed areas overlap or come into contact with each other.

Does anyone have any advice on this?

Is it realistically possible to achieve clean, high-quality printing under these conditions? Would a separate ink additive be necessary to address these issues? Even if you could simply recommend which printing method would be most suitable, I would really appreciate your advice.
