DTF Gang Sheet Artwork Requirements & File Setup Guide

When preparing artwork for DTF gang sheet printing, correct file setup and realistic colour expectations are essential for achieving reliable, high-quality results.
This guide outlines our artwork requirements, file setup standards, advanced editing considerations, and DTF colour system limitations, helping you avoid common issues such as print defects, unexpected colour shifts, or production delays.

Whether you are a designer, apparel decorator, or experienced print professional, following these guidelines ensures your gang sheets are printed accurately and efficiently.

Advanced DTF Gang Sheet Editing Skills

(For Consistent Quality & Long-Term Durability)

The following guidelines cover advanced production-level considerations. These are especially important when working with small text, thin lines, or mixed design elements.

Recommended File Formats & Size Limits

PNG Files (Strongly Recommended)

• 300 DPI

• Transparent background

• Maximum size: 58 cm (W) × 500 cm (L)

PNG files provide the most reliable control over white base settings and fine details.

Vector PDF Files (Use with Caution)

• Maximum size: 58 cm (W) × 250 cm (L)

Long vector PDFs increase the risk of white base inconsistencies and processing errors in DTF workflows.

Do Not Mix Large & Small Elements in One File (Critical)

Please separate:

• Large, bold logos or solid graphics

• Very small text or thin line elements

Why this matters

Large graphics and fine details require different white base choke settings.
Combining them in one file can result in:

• Small text disappearing

• Unwanted white outlines

• Weak adhesion in fine details

Always supply these elements as separate files.

Separate White vs Coloured Small Text (Important)

For small fonts or thin lines, please supply:

• One file for white-only small text or lines

• One file for coloured small text or lines

Why this matters

White and coloured elements require different white choke values.
Separating them allows precise adjustment so that:

• White text remains visible

• Coloured text does not show white edges

Minimum Line & Text Thickness (Adhesion Safety)

• Recommended minimum: 0.6 mm

• Absolute minimum: 0.5 mm

Elements thinner than 0.5 mm may not hold enough adhesive powder, which can lead to:

• Peeling

• Poor bonding

• Failure during heat pressing

For best durability, avoid anything below 0.5 mm entirely.

Before You Upload – Final Checklist

Before submitting your file, please confirm:

• PNG format, 300 DPI, transparent background

• 58 cm fixed width, correct final size

• No semi-transparency or ultra-thin details

• Large graphics separated from small text

• White small text separated from coloured small text

Print Responsibility & Limitations

All DTF gang sheets are printed exactly as supplied.
By submitting artwork, you acknowledge that print results are subject to the technical limitations of DTF printing and the quality of the files provided.

Copyright & Usage Responsibility

Please ensure you have the legal rights to use all submitted artwork.

We do not verify copyright ownership and accept no liability for copyright infringement.
By submitting files, you confirm that you own the rights or have permission to use the images for printing.

Colour Matching & Colour System Limitations

(Important Before You Design)

Colour accuracy is one of the most common concerns in DTF printing.
To avoid misunderstandings, it is important to understand how screen colours, print colour systems, and physical ink limitations work.

Color Accuracy Notice: Why “What You See” is Not Always “What You Get”

A common challenge in the DTF industry is the discrepancy between colors seen on a digital screen and the final printed result. This occurs because screens display colors in RGB (light-based), while DTF printing uses CMYK (ink-based). These two color spaces have different gamuts, meaning some vibrant colors on your monitor simply cannot be perfectly replicated with physical ink. To achieve the best results, we recommend designing your artwork within the CMYK color space..

RGB vs CMYK – Screen Colours vs Print Colours

Designs viewed on a screen are displayed using the RGB (Red, Green, Blue) colour model, which is fundamentally different from the CMYK (Cyan, Magenta, Yellow, Black) colour model used in printing.

• RGB is a light-based colour system used by monitors, phones, and tablets

• CMYK is an ink-based colour system used by printers

Because RGB uses light, it has a much wider colour gamut, especially in:

• Bright blues

• Neon greens

• Vivid purples

These colours cannot always be reproduced accurately in CMYK printing.

As a result, it is not possible to colour-match prints solely based on how colours appear on a screen, even if the screen looks calibrated.

While PNGs are RGB files, please ensure your design uses colors within the CMYK printable gamut to avoid unexpected color shifts during printing.

Pantone (PMS) vs CMYK – Spot Colours vs Process Printing

Pantone (PMS) colours are part of a separate, standardised spot colour system, designed to achieve highly specific colours using pre-mixed inks.

Many Pantone colours:

• Use special pigments

• Fall outside the printable CMYK colour gamut

• Cannot be reproduced exactly using CMYK inks alone

While we can aim to visually match or get close to a requested Pantone colour, exact Pantone-to-CMYK matching is not always achievable, especially for:

• Fluorescent colours

• Extremely bright blues and greens

• Highly saturated spot colours

Our ICC Profile & Professional Colour Calibration

Our DTF printing system uses custom-calibrated ICC profiles to ensure consistent and accurate CMYK reproduction.

These ICC profiles are created using:

• Professional colour measurement equipment – Barbieri Spectro LFP
  https://www.barbierielectronic.com/spectro-lfp

• Carefully matched combinations of our brand DTFhub consumables:

  • High-quality DTF inks
    DTF Ink (DTFhub) CMYK+W 

  • Professional DTF transfer films
    DTF Transfer Film Sheet (DTFhub)  

Through extensive testing and calibration, our ICC profiles are optimised to:

• Accurately reproduce international CMYK standards

• Deliver consistent colour output across prints

• Minimise unexpected colour shifts

For best results, we strongly recommend designing artwork in CMYK colour mode rather than RGB.

CMYK Colour Chart | CMYK Printed Colour Sample (Strongly Recommended)

If precise colour reference is required, we recommend purchasing our CMYK Colour Chart | physical CMYK printed colour sample.

• Length: 2 metres

• Printed using our production ICC profile

• Provides a real-world reference for:

  • Colour selection

  • Design adjustments

  • Customer approval before full production

DTF Gang Sheet Transfer CMYK Colour Chart (ICC Profile Matched)

Using a physical colour sample is the only reliable way to evaluate printed colours, as screen previews cannot accurately represent final printed output.

Important Colour Disclaimer

Due to the inherent differences between RGB, CMYK, and Pantone colour systems:

• Exact colour matching based on screen display is not guaranteed

• Pantone colours may only be approximated, not perfectly matched

• Final print results depend on:

  • Colour system used in the design

  • File preparation

  • Printing material limitations

All artwork is printed as supplied, using our calibrated CMYK workflow.
