Must Read Before Uploading Your Work
Accepted File Types
For optimal DTF printing results, vector files are preferred. If you're using raster images, high-quality PNG files are the recommended format.
Color Considerations
DTF printing uses the CMYK color model, so colors outside the CMYK spectrum may not print accurately.
Required Line Width
For standalone or free-floating lines, a minimum line width of 0.019" (1.4 pt) is recommended. Lines thinner than this may not adhere properly to the garment during printing.
Image Resolution / Pixel Count
For the optimized print quality, raster images should be at 300 DPI (dots per inch). Using a lower DPI may lead to pixelation or blurry results when printed. The gang sheet builder will notify you if your image resolution is too low.
Show-Through and Hand Feel
Designs with more show-through (negative space) allow for better breathability and result in a softer, more natural hand feel on the garment.
Semi-Transparent Pixels Can Cause White Outlines
When submitting PNG files, ensure there are no semi-transparent pixels along the edges of your design. These can result in unwanted thin white outlines during printing.
Soft Edges
Designs with soft edges or fadeouts (such as outer glows) can produce an unwanted white halo around the DTF print. To achieve a fadeout effect without this issue, consider using the halftone technique during the design process.
Transparent Background
Ensure your design has a transparent background before submitting. DTF printing will reproduce everything in the file—including any white backgrounds, which will be printed as part of the design.
Color Matching
SpeedETransfers is not responsible for slight color differences between your on-screen digital artwork and the final DTF (Direct-to-Film) transfer. Color appearance can vary depending on your screen settings and device type. For optimized results and color accuracy:* Always include HEX codes in your artwork’s color guide * Our printers are calibrated using CIELAB color profiles, ensuring professional-level color reproduction * Keep in mind that your screen may not be showing the exact printed colorsTo improve color consistency: * Use an IPS monitor for better color accuracy * Calibrate your monitor to the CIELAB color space for more reliable results * Email us at SpeedE@speedetransfers.com to request Pantone-matching services * Order a printed color swatch to select colors physically and reduce guesswork during the design processAt SpeedETransfers, we strive to give you the most accurate and high-quality DTF prints possible. Taking these steps will help you get results that closely match your creative vision.
Why Proper Artwork Preparation Is Important
Proper artwork preparation ensures your DTF transfers print with sharp detail, accurate color, and clean edges. High-quality artwork allows the printer to reproduce your design exactly as intended without distortion, pixelation, or color shifts. Poor artwork quality can result in blurry prints, jagged edges, or unexpected color changes.
Submitting correct artwork also helps prevent production delays. When artwork meets all requirements, your order can move directly into printing without needing corrections or adjustments. This ensures faster turnaround time and professional-quality DTF transfers.
Artwork File Format and Preparation Guidelines
Vector files are the best option for DTF printing because they can scale to any size without losing quality. These formats maintain sharp edges, smooth curves, and clean details regardless of enlargement.
Recommended vector formats include:
AI (Adobe Illustrator)
EPS
SVG
PDF (vector format)
Raster files are also accepted when prepared correctly. Recommended raster formats include:
PNG (preferred for transparency support)
PSD (Adobe Photoshop layered file)
Avoid using low-quality formats such as JPG whenever possible. Compression can introduce unwanted artifacts, reduce clarity, and affect final print quality.
Always submit files at the exact print dimensions to ensure accurate sizing and proper output.
Resolution Requirements for DTF Printing
High resolution is essential for producing sharp, clean, and professional transfer results. Files should be prepared at:
300 DPI at actual print size
Low resolution may cause:
Blurry output
Jagged or pixelated edges
Loss of small details
Proper resolution ensures smooth lines, readable text, and crisp graphics during printing.
Transparent Background Requirements
A transparent background is required to achieve clean transfer results. Any visible background, including white areas, will be printed as part of the design.
To prepare files correctly:
Remove all background layers
Export with transparency enabled
Save using PNG or PSD format
Transparency allows accurate edge definition and ensures only the intended design is transferred.
Color Accuracy and Print Matching
Color may appear differently between digital screens and printed transfers. This happens because screens display RGB color, while printers use CMYK.
To improve color accuracy:
Use CMYK color mode when possible
Provide HEX or Pantone references if exact matching is required
Avoid overly bright RGB colors that cannot be reproduced in print
Following these steps helps achieve consistent and accurate color reproduction.
Common File Preparation Mistakes to Avoid
Avoid these issues to ensure the best results:
Resolution below 300 DPI
Solid or white backgrounds
Soft or semi-transparent edges
Extremely thin lines
Pixelated or blurry graphics
Incorrect sizing
Proper preparation prevents delays and ensures consistent print quality.
Submission Checklist
Before uploading your file, confirm the following:
Resolution is set to 300 DPI
Background is fully transparent
Size matches the intended print dimensions
File format is PNG, PSD, AI, EPS, or SVG
Colors are properly prepared
Following these guidelines ensures fast processing and professional transfer results.
