The Golden Rule for Clear PET Boxes – Always Use White Ink Underlay

The Tip: When designing graphics for PET/PVC clear plastic boxes, always remember that standard offset inks are translucent. If you print a colored logo directly onto a transparent plastic surface, the light will shine right through, making your brand colors look weak and washed out.

The Solution: Our prepress engineers automatically apply a white ink underlay (白墨衬底) directly beneath your colored graphics. This creates an opaque barrier, ensuring your brand colors remain incredibly vibrant and true to your Pantone specs, even on a 100% transparent box.
