2. Automotive and Manufacturing

Step-by-Step Guide to Using Plastisol Ink
1. Prepare Your Tools
Choose the right screen:
- 110-160 mesh count for small details.
- 60-86 mesh count for thick ink layers. Clean your material: Wipe surfaces with rubbing alcohol first.
2. Printing Tips
Fix thin ink: Add curable reducer (like Wilflex additives). Stop ink bleeding: Keep the screen slightly raised off the fabric.
3. Curing the Ink
Perfect cure: Heat the ink to 320°F–330°F for 60–90 seconds. Check the temperature: ใช้ laser thermometer for accuracy. Too hot? Ink becomes brittle. Too cold? Ink washes off.
