• Synonymにじみ出るにじみでるNeutralMeans oozing out to the surface, and figuratively character showing through naturally, as in 「人柄がにじみ出る」; 「滲む」 itself is more for ink blurring or tears welling up.
• Synonymしみ出るしみでるNeutralLiquid slowly seeping from inside to the outside, as in 「汗がしみ出る」; works in both speech and writing, and unlike 「滲む」 it has no sense of blurring or spreading.
• AntonymはじくNeutralRepels water rather than absorbing it, as in 「油が水を弾く」; the opposite of 「滲む」 — liquid beads up and rolls off instead of soaking in and spreading.

Use 「滲む」 for ink bleeding, sweat or tears seeping out, or outlines blurring, as in 「インクが滲む」 and 「涙が滲む」. For liquid coming through to the surface say 「にじみ出る」, and for slow seeping out say 「しみ出る」.
