Reflective flex and flock materials are typically cut using a plotter with a 45° knife, but adjustments to speed and pressure are often needed. For best results, reduce the plotter’s speed and increase the blade pressure slightly from standard vinyl-cutting settings. Hand-cutting with pointed scissors is also possible, especially for smaller designs. 

Cutting with a Plotter:

• Blade: A 45° knife is recommended. 
• Speed: Slow down the plotter’s speed to ensure accurate cuts, especially for intricate designs. 
• Pressure: Increase the blade pressure slightly from typical vinyl-cutting settings. 
• Blade Depth: Adjust the blade depth to just cut through the material without damaging the carrier sheet. 
• Blade Holder: Ensure the blade holder swivels smoothly, potentially requiring occasional lubrication. 
• Cutting Strip: Regularly check and maintain the cutting strip’s surface, ensuring it is smooth to prevent cutting issues. 

Additional Tips:

• Material Type:Reflective flex and flock materials have different characteristics. Reflective flex is known for its smooth, flexible finish, while flock material has a textured, velvety feel. 
• Weeding:After cutting, the excess material (weeding) can be removed. Good lighting and weeding tools (like dental picks or tweezers) can be helpful, according to a blog post from hingstssignpost.com. 
• Test Cuts:Before committing to a large design, it’s advisable to perform test cuts to fine-tune the plotter settings and ensure optimal results. 
• Application:Once cut and weeded, these materials are typically applied to fabric using a heat press. 
• Material Compatibility: Consider the fabric type when applying heat transfer vinyl (HTV). Some materials may not be suitable for certain HTVs, especially those with hydrophobic impregnation or those prone to migration.
