Code 0007: Registration colour

What is the problem?

In a CMYK document, colours are created by mixing varying amounts of Cyan, Magenta, Yellow, and Black inks. Registration black is a special swatch that appears in your Swatches palette as “Registration”, and represents a mix of 100% of all four inks.

Although it appears black, Registration black should never be used as a substitute for regular black text or design elements. It serves a specific technical purpose in printing, typically for crop marks, registration marks, and alignment targets.

Using Registration black elsewhere in your artwork can cause printing issues, and should be avoided. Always use a standard black (e.g. 100% K or rich black) for design elements and text.

How do I fix it?

1. In the top menu, go to Window > Swatches to open the Swatches panel.

2. Locate the Registration swatch. It is usually the second swatch in the list and may appear as a small target icon on white or solid black, depending on your view settings.

3. Click the Registration swatch to select it.

4. Draw a small square somewhere off to the side of your document. Set both the Fill and Stroke of this square to Registration.

5. Click to select the square.

6. In the top menu, choose Select > Same > Fill Color.

   This selects all objects in your document using a Registration fill.

7. Open the Color panel and set the sliders to:

   C 0% / M 0% / Y 0% / K 100%

   This converts all Registration fills to true 100% black.

8. Deselect everything, then select your square again.

9. In the top menu, go to Select > Same > Stroke Color.

   This selects all objects using Registration as a stroke.

10. In the Color panel, set the sliders again to:

    C 0% / M 0% / Y 0% / K 100%

    This converts all Registration strokes to true black.
