Set the print size first
Prepare artwork at the dimensions you want on the garment. Raster artwork should have 300 DPI at that size.

ARTWORK
GUIDELINES.
A few checks before uploading help your artwork print at the size and appearance you intend.
BEFORE YOU UPLOAD
Choose a real cutout
Use actual transparency wherever you do not want a background printed. White is a color, not transparency.
Keep the intended orientation
Do not mirror your artwork unless you deliberately want a reversed result.
Inspect the small details
Check for stray pixels, white halos and partially transparent edge remnants. Very thin strokes and tiny text can be difficult to reproduce reliably.
Prepare raster color in RGB
RGB is recommended for raster artwork. Review color on the garment; a screen preview is not a physical proof.
Plan the sheet
The full printable width is 29.00″. For a finished sheet, leave at least 0.20″ between separate designs as our recommended spacing.
CHOOSE YOUR WORKFLOW
INDIVIDUAL DESIGNS
Use Build A Gang Sheet. Upload each artwork, set its intended size and quantity, and let the builder place the transfers. Shape Based Nesting uses actual contours to help reduce unused film.
Image Spacing controls separation between transfers. Transfer Labels are optional printed labels. Gang Sheet Name is reference information only and is not printed.
BUILD A GANG SHEETA SHEET YOU HAVE ALREADY ARRANGED
Use Upload Print Ready. Make the finished sheet at its intended final dimensions, no wider than 29.00″. Leave the recommended 0.20″ between independent designs. This spacing is between artwork, not a required roll-edge margin.
Include only what you want printed. Remove unwanted crop notes and instructions, check backgrounds, spelling and orientation, and export one finished sheet per file. Multi-page documents and animated images are not supported.
Reliable physical dimensions are read automatically. When size information is missing or ambiguous, enter the intended width when prompted; proportions stay locked.
UPLOAD PRINT READYFILES THAT WORK WITH imDTF
BUILD A GANG SHEET
PNG, JPG/JPEG, WebP, TIFF.
100 MB per file.
UPLOAD PRINT READY
PNG, JPG/JPEG, WebP, TIFF, BMP.
2 GB for PNG and TIFF; 100 MB for other supported formats per file.
- PNG and TIFF
- PNG is a strong choice for raster artwork that needs transparency. TIFF suits high-resolution raster sheets; export a single page and preserve transparency when needed.
- JPG / JPEG
- JPEG has no transparency. Any white or colored background in the image will print.
- SVG, EPS and PDF
- Temporarily unavailable. Export PNG or single-page TIFF at 300 DPI at the intended print size.
- WebP and BMP
- Still WebP can preserve transparency. BMP is available in Upload Print Ready and requires intended-width confirmation; do not rely on BMP to preserve a transparent background. Use PNG when transparency matters.
- Design-source files
- PSD, AI and CDR are not accepted. Export your artwork to a supported format before uploading.
File size is only one limit. Image dimensions also matter.
LOOK CLOSELY BEFORE PRINTING
BACKGROUND AND EDGES
A white background is not transparency. A visible background is part of your artwork and may print. imDTF does not automatically remove it.
Inspect your export on both light and dark backgrounds. Look for unwanted white halos, feathered edges, partially transparent remnants and stray pixels.
SIZE AND IMAGE DETAIL
Aim for 300 DPI at the intended print size. Enlarging a raster image lowers its effective DPI; changing the DPI number alone does not add image detail. Review the effective DPI shown by the builder.
Vector shapes can scale differently from raster images, but a vector document does not improve the resolution of photos or other raster content inside it.
COLOR ON THE GARMENT
imDTF uses 9 Color Extended Gamut with Fluorescent Inks. Screen previews are not physical print proofs, and monitors vary. Fluorescent and extended-gamut printing can appear different from standard screen RGB.
No exact Pantone match is promised. If color is critical to your project, contact us before ordering.
FROM FILE TO FABRIC
PRESSING INSTRUCTIONS
STANDARD / MOST GARMENTS
- Temperature
- 300°F
- Press time
- 8–10 seconds
- Pressure
- Firm pressure · 60 PSI or higher
- Peel
- Peel immediately while hot or after cooling.
- Repress
- 5–10 seconds
POLYESTER
275–285°F
Use the same time, pressure, peel and repress steps. The lower temperature helps reduce heat-related issues.
Heat presses and garments can vary. Test when working with unfamiliar or heat-sensitive materials.
