Marking Process: Silk Screen Printing

Silk Screen Printing Technical Requirements

1. The appearance surface must be free from obvious dirt, ink residue, missing prints, blurred/broken lines, uneven ink thickness, misalignment, scratches, and other defects.
2. Printed content, fonts, font sizes, CMYK values (color codes), and patterns must be consistent with samples. Text must not show jagged edges.
3. Adhesion Test: Clean the printing area with 99.5% anhydrous alcohol. After drying, apply 3M600 tape to the printed area, using a pencil eraser to enhance contact. After 90 ± 30 seconds, quickly pull off the tape vertically from one end. Repeat 5 times in the same position. The print is considered qualified if no visible detachment occurs.
4. Alcohol Resistance Test: Soak a pure cotton cloth with >99.5% anhydrous alcohol, wrap it around a dedicated 500g weight (approx. 1cm² contact area). Wipe the sample surface back and forth 50 cycles at 40-60 cycles/minute, with a stroke of about 20mm. The print is considered qualified if the font shows slight wear and fading but remains complete and clearly legible.
5. Abrasion Resistance Test: Use a dedicated Japanese sand eraser (model: LER902K) with a 500g load. Wipe the sample surface back and forth 50 cycles at 40-60 cycles/minute, with a stroke of about 20mm. The print is considered qualified if the font shows slight wear and fading but remains complete and clearly legible.
6. All materials must comply with RoHS environmental requirements.

Laser Engraving Technical Requirements

1. The appearance surface must be free from obvious dirt, residue, missing engravings, blurred/broken lines, burrs, bubbles, scratches, and penetration defects.
2. Printed content, fonts, patterns, and positions must be consistent with samples. Font sizes must be uniform, and text must not show jagged edges or corrosion.
3. Alcohol Resistance Test: Soak a pure cotton cloth with >99.5% anhydrous alcohol, wrap it around a dedicated 500g weight (approx. 1cm² contact area). Wipe the sample surface back and forth 50 cycles at 40-60 cycles/minute, with a stroke of about 20mm. The print is considered qualified if the paint layer does not change color or detach from the substrate.
