How to Use Vexels and Color Knockouts for Breathable Heat Transfer

For anyone diving into Direct-to-Film (DTF) printing, the weight and stiffness of large transfers can be a real hurdle. Color knockouts solve this by removing solid color blocks that add bulk. Paired with Vexels, a user-friendly web design tool, you can achieve lightweight, stretchy, and breathable prints that press smoothly onto garments. This guide will walk you through every step—from choosing templates in Vexels to vectorizing and applying knockouts, all the way to heat-pressing on your favorite blanks.

What Are Color Knockouts in DTF Printing?


Color knockouts are simply areas in your design where a specific color—often white—is omitted so the shirt fabric shows through. This reduces ink layers, making the print:

  • Thinner and softer, so it feels less like a sticker.
  • More breathable, perfect for big graphics.
  • Stretchier, minimizing cracking or peeling during wear.

Traditional DTF transfers use a solid white underbase that can make prints stiff. By strategically removing white behind colored artwork, your designs remain vibrant but super light.

Why Choose Vexels for Knockout-Ready Designs?


Vexels is built for creators at all skill levels. It offers:

  1. Intuitive Interface
    Right after logging in, you’ll find a clear “Create Design” button. No complex menus—just straightforward options to jump into your project.
  2. Extensive Template Library
    From floral motifs to bold typography, Vexels hosts thousands of merch-ready templates. Pick one that suits your brand or client’s vibe, then customize.
  3. Vector Export with Transparency
    Designs download as transparent PNGs. This means no background fuss—everything is set to vectorize immediately, making knockout areas easy to isolate.
  4. Smart Color Limiting
    Vexels’ vectorizer supports up to 12 colors. Limiting colors helps maintain crisp edges and reduces file complexity, crucial for effective knockouts.

With Vexels, pro-level DTF designs become a few clicks away—even if you’ve never opened Illustrator.

Step-by-Step: Creating Your First Knockout Design



1. Select and Customize a Template


  • Hit Create Design on Vexels’ homepage.
  • Browse categories like “Spirit Glides” or “Ramen” for bold artwork.
  • Replace placeholder text with your own—e.g., change “Your Logo” to “DTF Superstar.”
  • Rearrange elements until the layout feels balanced.


2. Export as Transparent PNG


  • Click Download and ensure “Transparent Background” is enabled.
  • Save the file locally.


3. Vectorize Your Design


  • Upload the PNG into Vexels’ vectorizer tool.
  • Set the color limit to 12. This keeps the design manageable and true to the original palette.
  • After vectorization, identify areas to knockout—usually the white underbase behind key colors.


4. Adjust Opacity for Knockouts


  • Use the vector editor to slide down opacity on white fills.
  • Keep darker outline colors at full opacity to maintain definition.
  • Preview your design on both light and dark backgrounds to ensure knockouts appear where you intend.


5. Finalize and Download


  • Confirm the design still exports as PNG with transparency.
  • Download the optimized file ready for printing.

Applying Your Knockout DTF Transfer



Choosing the Right Blanks


  • Smart Blanks 402 (black and white) are reliable staples. They offer a flat, smooth surface that showcases breathable prints perfectly.
  • For darker shirts, black blanks paired with knockout designs give a neat matte finish without a heavy white base.


Heat Press Settings


  • Temperature: 300°F
  • Time: 7 seconds per press
  • Pressure: Medium to firm
  • Technique:
    • Pre-heat press for alignment using built-in lasers.
    • Thread the shirt easily and align your transfer from edge to edge of the collar.
    • Use a matte finishing sheet for a second press to seal edges and boost softness.


Pressing Workflow


  1. First Press – Lay the transfer on the shirt, check laser alignment, and apply for 7 seconds.
  2. Peel – Remove the film while still warm for a crisp pull.
  3. Second Press – Cover with matte sheet and press again for 7 seconds. This locks in the knockout effect and smooths edges.

Troubleshooting Common Knockout Issues


  • Uneven Edges: If you see bits of white showing, ensure opacity sliders on white fills are turned fully down.
  • Too Rigid Print: Confirm that all large white underbases are knocked out. Even small white patches add bulk.
  • Color Loss: Keep outlines and key color fills at full opacity. Only remove white underbase layers, not the artwork itself.

Boosting Your DTF Workflow: Tips and Tricks


  • Batch Processing: Create multiple designs at once in Vexels, then vectorize in one go to save time.
  • Mockup Preview: Test your knockout designs on virtual shirt mockups in Vexels before exporting.
  • Stay Within Color Limits: More than 12 colors can muddy the vectorization process. Simplify designs if needed.
  • Use Matte Finishing Sheets for every print to enhance softness and durability.

Why Breathability Matters


Breathable prints aren’t just more comfortable—they stretch with the fabric, reducing cracking and extending the life of your garment. By eliminating unnecessary white layers, your customers feel the fabric, not the print. This creates a professional look and feel that sets your products apart.
