The production process for RoHS stickers is similar to that of ordinary stickers, but the core requirement is to ensure the regulatory compliance and durability of the materials and inks themselves.

Here is a brief introduction to the manufacturing process:

Simplified RoHS Sticker Production Process

1. Regulation & Design Confirmation:

   • Determine the RoHS regulation version (e.g., EU or China) the sticker must comply with, and the required markings (e.g., mark, restricted substance declaration).

   • Select sticker materials and adhesives (e.g., PET, PI) that are heat-resistant, chemical-resistant, and RoHS compliant themselves.

2. Pre-Press Artwork Finalization:

   • Design the label graphics, text, and traceability information (barcode/serial number).

   • Use professional software to finalize the artwork, ensuring text is converted to outlines and images are clear.

3. Printing & Ink Selection:

   • Choose a printing technology (e.g., digital, flexographic, screen printing) based on quantity and complexity.

   • Must use RoHS Compliant inks or thermal ribbons to ensure the ink is free of restricted hazardous substances.

4. Post-Processing & Forming:

   • Lamination or varnishing is typically applied to enhance the sticker's abrasion resistance and durability.

   • Use a die-cutting machine for die-cutting into the final shape (sheets or rolls).

5. Quality Inspection & Delivery:

   • Inspect the sticker for clarity, adhesion, and durability.

   • Most Crucial: The RoHS Declaration of Conformity (DoC) for the sticker material and ink must be provided for the manufacturer's traceability and documentation.
