Master Printing & Heat Press Guide
Brought to you by Source Printing
This guide provides the technical settings and professional tips required for high-quality transfers. Please note that these are guidelines; we always recommend a small test press as environmental factors (like humidity and altitude) can affect results.
Section 1: Sublimation Guidelines
Sublimation is a process where ink turns into gas to bond with polyester-coated “blanks”. Note: You cannot sublimate onto 100% cotton without special sprays.
Essential Sublimation Settings
| Blank Item | Temperature (°C) | Time (Seconds) | Professional Tip |
| Ceramic Mugs | 180°C | 80s | Secure with heat tape. Let the mug heat up with the press before starting the timer. |
| Polyester T-Shirts | 180-200°C | 45s | Use Teflon sheeting and plain white paper inside to prevent ink bleeding to the back. |
| Cotton T-Shirts (Light) | 180°C | 40s | Requirement: Use Cotton Sublimation Spray before and after pressing. |
| Glass / Mason Jars | 180°C | 180s | Caution: Glass must warm up gradually with the press from a cold start to prevent cracking. |
| Aluminium Bottles | 190°C | 70s | Avoid over-tightening the tension knob to prevent the bottle from bending. |
| Mouse Pads | 190°C | 65s | Ensure even pressure for a sharp edge-to-edge finish. |
| Rock Slate | 180°C | 180s | Use firm pressure to ensure the image transfers into the stone’s texture. |
| MDF / Wood Items | 180°C | 80s | Works for coasters, keychains, and luggage tags. |
| Non-Woven Bags | 110-120°C | 15-20s | Tricky: These can melt easily. Start at a low heat and work up slowly. |
Section 2: DTF (Direct-To-Film) Guidelines
DTF is highly versatile and works on almost any fabric, including dark cotton and polyester.
Essential DTF Settings
| Fabric Type | Temperature | Time | Pressure |
| 100% Cotton | 150°C – 160°C | 10 – 15s | Medium / High |
| Polyester / Blends | 140°C – 150°C | 10 – 12s | Medium |
| Nylon / Delicate | 140°C | 8 – 10s | Medium |
The DTF Workflow
- Pre-Press: Press your garment for 5–10 seconds before applying the transfer. This removes moisture and wrinkles for a better bond.
- Positioning: Place the DTF film with the printed side down. Cover with a Teflon sheet or parchment paper.
- The Press: Apply firm, even pressure.
- The Peel: For Source Printing DTF, we recommend a Cold Peel. Allow the garment to cool completely (approx. 30–60 seconds) before removing the film.
- Finishing Press: After peeling, press the design again for 5 seconds with a Teflon sheet to secure the edges and give it a professional finish.
Section 3: Design & Artwork Requirements
To ensure your prints aren’t pixelated, follow these exact specifications:
- Resolution: Minimum 300 DPI at actual size.
- File Formats: PDF (preferred), AI, CDR, or high-res PNG with transparent backgrounds.
- Color Mode: Save your files as CMYK (for standard printing) or RGB (for specific industrial DTF workflows).
- Mirroring: DO NOT mirror your artwork for DTF; our software handles this. For Sublimation, artwork should usually be mirrored.
- Minimum Detail: Lines should be at least 1mm thick. Fine text or thin “hairlines” may not adhere correctly.
Section 4: Care & Maintenance
Protect your investment and your prints:
- Washing: Wait at least 24 hours before the first wash. Wash garments inside out in cold or cool water.
- Drying: Air dry only. Do not tumble dry.
- Ironing: Never iron directly onto the print. Iron on the reverse side using a low heat setting.
- Machine Safety: If the heat press is not used for 10 minutes, switch it off. Never touch the heating plate while it is on.
