About CMYK Over Foil

Printable silver foil creates a metallic foundation that can be overprinted with CMYK inks. This technique allows for vibrant metallic colors while maintaining precise registration and detail in the printed artwork. The silver base adds a luminous quality to the colors printed on top.

Unlike traditional foil stamping where foil sits on top of printed artwork, printable foil acts as a base layer. The CMYK process colors print directly onto the metallic surface, creating rich, shimmering effects that combine the precision of digital printing with the elegance of metallic finishes.

Best Practices

File Setup

Adobe Illustrator

HP Foil with CMYK Overprint

Setting up printable foil as a base layer in Adobe Illustrator

Step 1 of 10
Illustrator Swatches Panel

Open the Swatches Panel

In Adobe Illustrator, go to Window > Swatches to open the Swatches panel. This is where you'll create the HP Foil spot color for the metallic base layer.

💡

You can also use the keyboard shortcut F5 to toggle the Swatches panel.

Selection of Foil Artwork

Select Foil Artwork

Select all the artwork elements that should print as the metallic foil base layer. For CMYK over foil, this is typically a solid shape that defines the metallic area.

💡

The foil layer acts as a base - CMYK will print on top of it to create metallic colors.

New Swatch Dialog

Create New Spot Color Swatch

Click the Swatches panel menu and select New Swatch. In the dialog:

  • Swatch Name: HP Foil
  • Color Type: Spot Color
  • Color Mode: CMYK
  • Set Cyan to 100% (for visibility)
⚠️

Critical: The name must be exactly HP Foil with correct capitalization for the press to recognize it.

Swatches Panel with HP Foil

Verify Swatch Created

Your Swatches panel should now show the HP Foil spot color swatch. It will appear with a white triangle in the corner indicating it's a spot color.

💡

The spot color indicator (white triangle) confirms the color will output as a separate ink channel.

Applying Spot Color

Apply Spot Color to Artwork

With your foil artwork selected, click the HP Foil swatch to apply it as the fill color. The artwork will appear cyan (the preview color) but will print as metallic silver foil.

💡

The cyan preview is just for visibility - the actual output will be metallic foil on press.

Windows Menu - Attributes

Open the Attributes Panel

With your HP Foil artwork still selected, go to Window > Attributes to open the Attributes panel. This panel controls overprint settings.

⚠️

Important: The next step is critical - foil must be set to overprint for proper layering with CMYK.

Attributes Panel - Overprint Fill

Enable Overprint Fill

In the Attributes panel, check the Overprint Fill checkbox. This ensures the foil prints correctly with the CMYK artwork layered on top.

⚠️

Critical: Foil must be set to overprint. Without this setting, the foil and CMYK layers won't combine properly.

Illustrator Layers Panel

Verify Layer Order

Open the Layers panel (Window > Layers) and verify your layer order:

  • Top layer: Foil (prints first as base)
  • Bottom layer: CMYK (prints on top of foil)
💡

In Illustrator, layer order is reversed from print order - items at the top print first.

Overprint Preview showing combined artwork

View Overprint Preview

Go to View > Overprint Preview to see how the final print will look. You should see the CMYK artwork combined with the metallic foil base.

💡

Overprint Preview shows the actual appearance with transparency and overprint effects applied.

Separations Preview

Verify in Separations Preview

Go to Window > Separations Preview and check Overprint Preview. Toggle visibility to verify you see:

  • CMYK channels: Cyan, Magenta, Yellow, Black
  • HP Foil: Your foil base layer (separate spot channel)
💡

If HP Foil doesn't appear as a separate channel, the spot color wasn't created correctly. Go back to Step 3.
