Шелкография против цифровой и термотрансферной печати | Путеводитель по сумкам

Choosing the right custom bag printing method matters. Your logo is the face of your bag, but not all logos print equally well. At our factory in Xiamen, orders use three main approaches: silk screen printing, digital printing, and heat transfer printing.

Each method has strengths and limits. Here is how to choose the right one for your project.

Silk Screen Printing

Pros:

• Extremely durable — the ink bonds with the fabric and withstands hundreds of washes.
• Vibrant, opaque colors even on dark materials.
• Cost-effective at volume. Once the screen is made, each additional print is cheap.
• Soft hand feel on fabric. The ink sinks in rather than sitting on top.

Cons:

• High setup cost for small runs. Each color requires a separate screen.
• Not ideal for gradients, photographs, or highly detailed artwork.
• Minimum order quantity is 500 units for cost efficiency.

Cost indicator: $0.15–$0.40 per color per bag at 5,000 units. MOQ 500.

Digital Printing

Pros:

• No color limit. Full CMYK color range including gradients and shadows.
• No setup screens needed. Ideal for designs that change frequently.
• Sharp detail reproduction for intricate logos and photographic images.
• Economical at 500 units and above, especially for complex designs.

Cons:

• Sits on top of the fabric, creating a slightly raised feel.
• Less durable than silk screen under heavy washing or abrasion.
• Large solid areas can show texture from the fabric weave.
• Not recommended for bags that will be machine-washed frequently.

Cost indicator: $0.40–$0.90 per bag depending on size and coverage. MOQ 500.

Heat Transfer Printing

Pros:

• Excellent for small, detailed logos on tricky positions like handles or seams.
• Works well on materials that are difficult to print directly, such as coated fabrics.
• No color limit on the transfer film itself.
• Good for short runs and prototypes since setup is minimal.

Cons:

• The transfer film sits on top of the fabric, creating a noticeable raised edge.
• Can peel or crack over time, especially at fold lines or with heavy washing.
• Not suitable for large solid areas — the film may trap air bubbles.
• Less breathable than direct printing methods.

Cost indicator: $0.30–$0.70 per bag depending on transfer size. MOQ 500.

How to Choose Your Custom Bag Printing Method

Your Situation	Recommended Method
1–2 color logo, heavy-use bags, long lifespan	Silk Screen
Photo-realistic artwork, gradients, frequent design changes	Digital Printing
Small logo on handle, seam, or coated fabric	Heat Transfer
Dark fabric with bright logo	Silk Screen
Premium corporate gift, short-term campaign	Digital Printing or Heat Transfer
Budget priority, 5,000+ units, simple design	Silk Screen

Pro Tips from the Factory Floor

1. Test before you commit. We always recommend sampling when a buyer is undecided. A $30-80 sample fee saves regret later. Read more about screen printing history and technique to understand why setup matters.
2. Consider the bag material. Silk screen works on almost everything. Digital printing prefers smooth fabrics like RPET and non-woven. Heat transfer excels on coated or waterproof materials.
3. Match the method to the bag’s lifespan. A 5-year reusable grocery program deserves silk screen. A 3-month event promo can use digital printing or heat transfer.
4. Combine methods. Many buyers use silk screen for the main logo and heat transfer for a small inner label or handle detail.

Other Decoration Methods We Offer

Beyond the three main printing methods, our factory supports additional techniques to match your branding needs:

• Embroidery: Thread stitched directly into the fabric. Premium look and feel. Best for corporate gifts and high-end retail.
• Metal Badge / Label: Custom metal or PU leather tags sewn onto the bag. Adds perceived value and brand recognition.
• Woven Label: Integrated into the seam or hem. Ideal for care instructions, size labels, or subtle branding.
• Reflective Strip: Safety-focused decoration for sports and outdoor bags. Available in silver, color-shifting, or custom shapes.
