DTF（白墨烫画）方案介绍DTF (Direct-to-Film) Solution

DTF（白墨烫画）方案介绍

✅ 核心原理 先在 PET 离型薄膜上打印图案（CMYK + 白墨，深色面料必须白墨打底），打印同时撒热熔胶粉、烘干固化，得到一张带图案的烫画膜；后期使用热压机（120~160℃），将膜上图案热压转印到面料上，撕掉 PET 底膜，图案便留在布料表面。

✅ 工艺流程（4 步）

1. 打印：DTF 打印机在 PET 膜输出彩色 + 白墨图案

2. 撒粉 + 抖粉：喷上热熔胶粉，抖除多余粉末

3. 烘干固化：烘箱加热，使胶粉熔合附着在墨层上

4. 热转印：热压机压合至面料，冷却后撕膜，成品完成

✅ 适用材料（以面料为主） 棉、涤纶、棉涤混纺、尼龙、真丝、牛仔、帆布、摇粒绒、皮革、网布。浅色、深色面料均可印制。

对比：热升华仅适用于浅色涤纶面料。 ⚠️ 注意：普通 DTF 属于热转印工艺，主要用于纺织品；硬质材料需使用 UV DTF，二者不要混淆。

✅ 主流应用场景（POD 定制电商、工厂小批量订单）

• 服装类：T 恤、卫衣、工装、队服、潮牌、童装、帽子、帆布袋

• 纺织配饰：箱包、运动鞋面、抱枕、地毯、宠物服饰

• 订单模式：一件起印、小批量、多款式、快速换图，无需制版，非常适合跨境 POD、文创定制、企业礼品订单

✅ DTF 方案优势

• 面料兼容性极强，棉料、深色面料均可印制（DTG 仅适合浅色纯棉；热升华仅适合高涤浅色面料）

• 印花手感柔软，弹性佳，耐水洗、不易开裂

• 无需对面料做前处理（DTG 工艺需要喷涂前处理液）

• 烫画膜可提前批量打印储存，接到订单直接热压，交付速度快

• 支持小单生产，一件起做，图案可达到照片级高清效果

DTF (Direct-to-Film) Solution

✅ Core Principle Print graphics with CMYK + white ink on PET release film (white ink is mandatory for dark fabrics). Hot-melt adhesive powder is applied and cured during printing to form a transfer film. Use a heat press (120~160℃) to transfer the graphic onto textiles. Peel off the PET liner after cooling, and the pattern remains on the fabric.

✅ 4-Step Workflow

1. Printing: DTF printer prints CMYK and white ink onto PET film.

2. Powder Coating & Shaking: Apply hot-melt powder and shake off excess powder.

3. Curing: Oven heating fuses powder onto the ink layer.

4. Heat Transfer: Press onto fabric with heat press, cool down and peel liner to finish.

✅ Compatible Materials (Textile-focused) Cotton, polyester, poly-cotton blend, nylon, silk, denim, canvas, fleece, leather, mesh fabric. Works on both light and dark textiles.

Note: Regular DTF is for textiles only. For hard substrates, use UV DTF instead.

✅ Application Scenarios (POD e-commerce & small-batch manufacturing)

• Apparel: T-shirts, hoodies, workwear, team uniforms, streetwear, kids clothes, caps, tote bags

• Textile accessories: Bags, shoe uppers, cushions, carpets, pet clothing

• Order mode: No plate making, print-on-demand, fast artwork switching. Perfect for cross-border POD, custom gifts and promotional merchandise.

✅ Key Advantages

• Wide textile compatibility, works on cotton and dark garments (DTG limited to light cotton; sublimation only for light polyester)

• Soft, stretchable prints, good wash resistance and crack resistance

• No pre-treatment liquid required (required for DTG)

• Pre-print and store transfer films, fast turnaround for orders

• Low MOQ, support one-piece printing with photo-quality output
