Guide to creating a white layer

For your Custom Stickers

When designing stickers with transparent, mirror, or brushed alloy materials, you may require a white layer. This layer ensures that colors appear vibrant and opaque, as it provides a solid background on special materials where transparency is a factor.

Creating a White Layer in Adobe Illustrator: Step-by-Step

  1. Select Your Design Elements: Choose the parts of your design that need to be opaque.
  2. Create the 'HPI-White' Swatch: Fill the selected areas with a new swatch named “HPI-White.” Set the CMYK values for this swatch to 25% for each component (Cyan, Magenta, Yellow, and Black).
  3. Set to Spot Color: Ensure that you save this swatch as a Spot Color. This differentiates it from the rest of the CMYK colors in your design.
  4. Apply Overprint: Go to the ‘Attributes’ tab and select “Overprint fill” for the white areas. This ensures the white ink prints correctly without knocking out the colors beneath it.
  5. Save Your File: Once your white layer is properly set up, save your design as a CMYK PDF file.
  6. Upload and Note: When you upload the file to our website, please make a note specifying your use of the 'HPI-White' spot color. This helps us verify the accuracy of the white layer before printing.

FAQs About Creating a White Layer for Stickers

  • Why do I need a white layer for my stickers?

The white layer acts as a base for colored elements on materials like transparent, mirror, or brushed alloy, making them stand out as fully opaque and true to color.

  • Can I still have reflective elements on brushed alloy or mirror stickers?

Yes. If you want parts of your sticker to remain reflective, simply refrain from adding the 'HPI-White' layer behind those particular areas.

  • How do I indicate where I want the white layer to be printed?

In Adobe Illustrator, use the 'HPI-White' spot color to fill the areas where you want the white ink. Make sure to mark these with “Overprint fill.”
