Bleeding Ink on Anodized Parts

2001

My company silkscreens anodized aluminum cylinders. When we go to print BLACK, it wants to bleed shortly after it is applied. All other colors, besides blue occasionally, work fine. We have tried different inks, ink thicknesses, and also different screen meshes and tensions, but to no avail.

Please shed some light if you can as we are desperately wanting to resolve this issue.
