Why does my black logo appear on every printing separation?

Inspect the production artwork

A fictional stationery brand approves a black wordmark. In the printer’s separation preview, that wordmark appears on several plates. The screen mockup alone cannot explain the cause. Ask the designer to inspect the actual object color and swatch type, rather than regenerating a darker logo concept.

Adobe documents the special registration swatch. This is a production-file diagnosis, not a claim that every multicolor black object is necessarily using registration color.

Distinguish the possible color roles

The supplier must confirm the intended print method and color specification. Do not substitute arbitrary numerical ink values from another job. Keep legitimate printer marks separate from the logo artwork.

Repair the source file deliberately

Have the production designer change the inappropriate object color to the agreed specification and export a new reviewed file. Compare separations again. A corrected screen preview is insufficient if the wrong color definition remains in the exported PDF. Retain the earlier file with a rejected status to avoid reuse.

Review the wordmark and symbol together; imported groups may contain mixed color definitions. Do not flatten everything merely to hide the separation problem if editable artwork is required.

Approve the supplier proof

Confirm the revised file, intended ink role and proof with the printer. Itemlume’s generated logo image does not create print separations or select registration swatches; this issue arises during external artwork preparation. The useful next step is a file-level correction and supplier confirmation, not another prompt asking for “pure black.”
