Short answer: A custom logo or stamped tablet requires a custom-engraved punch — your logo, imprint code, or score pattern machined directly into the punch face — rather than any change to the press itself. The process is: submit artwork, get a proof before anything is ground, then wait on a lead time for the actual engraving (commonly a few weeks). Custom tooling costs meaningfully more than a stock die and takes weeks instead of shipping immediately, so it's worth validating your formulation on a stock shape first and moving to custom once the recipe is locked in.
Any tablet press that runs stock tooling can run custom-engraved tooling too — the press doesn't change, only the punch face does. What changes is the process and lead time to get that tooling made.
How Logo Engraving Works
A punch's face — the surface that contacts the tablet during compression — can be machined with a recessed or raised pattern instead of left flat or plain concave. Whatever pattern is on the punch face transfers onto every tablet it presses: a logo, a brand mark, an imprint code, or a score line for splitting the tablet in half. This is a modification to the punch itself, done during manufacturing — it's not something added after the fact to an existing stock punch.
Designing Artwork for a Punch
Not every logo translates well into an engraved punch face. Fine detail, thin lines, and small text all become harder to press cleanly the smaller and more intricate they get — a simpler mark with reasonably bold lines holds up far better under repeated compression than a highly detailed design. Expect to see an artwork proof before any grinding happens, which is the point to catch and simplify anything too fine to press reliably.
Ordering Custom Tooling
Custom engraved tooling starts from any of the standard stock shapes — round, oval, caplet, or square — with your artwork added to the punch face. As a reference point, our own custom engraving starts at $349 per set with a 3–4 week lead time after artwork approval, versus a flat rate and immediate shipping for a stock shape — custom tooling is a real cost and time premium over stock, which is exactly why it's worth saving for once your formulation is settled rather than for early testing.
Formulation Considerations for Clean Detail
Engraved detail is more prone to the picking defect — where powder catches in the fine detail instead of releasing cleanly — than a plain punch face. A formulation with adequate, well-mixed lubricant releases more cleanly from engraved detail; a formulation that's already borderline on sticking or picking with a plain punch will likely be worse with an engraved one. It's also worth cleaning engraved punches more attentively than plain ones, since residue accumulates in the fine detail first.
