Perché la carta per sublimazione è essenziale per la stampa su tessuto
Creato il 08.25
We must use sublimation transfer paper (as opposed to regular paper or other transfer papers) for fabric printing because it is specifically engineered to be a temporary, high-performance carrier for the solid sublimation ink. Its unique properties are essential for a successful, high-quality transfer.
Here’s a detailed breakdown of why it's necessary:
1. 它旨在“保持”墨水，但也“完全释放”它
This is the most critical function.
- 特殊涂层：升华纸的一侧有一层薄薄的工程涂层。该涂层略微多孔，旨在让打印机的液体升华墨水保持足够长的时间以便干燥，而不允许其过深地渗透到纸纤维中。
- 完整释放：在热压过程中，墨水必须直接从固体转化为气体（升华）。纸张的涂层允许≥90%的墨水以气体形式释放并转移到基材上。普通打印纸会过深地吸收墨水，将大部分墨水困在纸纤维中，导致转印效果模糊且斑驳。
2. 它防止墨水渗透和重影
- 精确度：涂层控制液体墨水的扩散，确保细节清晰、线条锐利、文本打印清晰。如果使用未涂层的纸张，墨水会向外渗透并羽化（就像水滴在纸巾上），导致边缘模糊和细节丧失。
- No "Ghosting": 因为墨水停留在涂层纸的表面，所以不会渗透到另一面。这防止了纸张的反面污染您的热压机或其他物品，并确保所有墨水都朝向织物，以实现高效转印。
3. 它管理湿度和干燥时间
- Moisture Control: Sublimation paper is manufactured to have very low moisture content. Why does this matter? Any moisture in the paper will turn to steam under the intense heat of the press. This steam can interfere with the sublimation process, causing blurred images and uneven color transfer.
- 快速干燥：该纸张设计用于使水性升华墨水在其表面迅速干燥，从而防止纸张在进入热压机之前过度卷曲或变形。
4. 它能承受高温和高压
- No Burning or Scorching: 在转印过程中，纸张会受到高温（通常为380°F - 400°F / 193°C - 204°C）和较大压力的影响。升华纸的配方旨在承受这些条件，而不会出现灼烧、燃烧或粘附在热压机或产品上。
What Happens If You Use the Wrong Paper?
To truly understand why sublimation paper is necessary, consider what goes wrong with alternatives:
- Regular Copier/Printer Paper: 纸纤维过于吸水。它们会吸收升华墨水，将其困住。在加热过程中，只有一小部分墨水会气化并转移，导致图像非常模糊、暗淡和褪色。图像也会感觉粗糙，因为你能感觉到已经与织物融合的纸纤维。
- 喷墨转印纸（适用于浅色织物）：这种纸张具有聚合物涂层，旨在熔化到T恤上。您正在转移整个塑料涂层，这会在织物上产生明显且通常较硬的手感。使用升华时，只有墨水气化并与聚酯纤维结合；纸张被丢弃，不会在织物上留下手感。
- Dark Transfer Paper (for Inkjet): This is also a plastic-like transfer that sits on top of the fabric, creating a thick, rubbery feel. It is a completely different process.
Key Properties of Good Sublimation Paper:
- Weight: 通常在29-120克/平方米之间。足够重以便通过打印机而不发生卡纸，但又足够轻以实现高效的墨水释放。
- Coating: 一种高质量、一致的涂层，仅在一侧。
- Curl: Minimal natural curl to ensure smooth printing and handling.
- Moisture Resistance: 抗吸收大气湿气，以确保结果的一致性。
In a Nutshell: The Analogy
将升华纸视为一种不粘烘焙纸。
- You put your raw cookie dough (sublimation ink) on it.
- The dough doesn't stick permanently to the sheet.
- 在烤箱（热压机）中，面团烹饪并转变。
- You then peel away the baking sheet (the paper), and you're left with a perfect, finished cookie (the printed product) with no residue from the sheet left behind.
Regular paper would be like using a porous wooden board—the dough would stick to it, burn, and you'd never get a clean, complete cookie off of it.
结论：使用升华转印纸不是建议；它是染料升华过程的基本要求。它是确保墨水从您的打印机精确、鲜艳和永久地转移到聚酯面料或聚合物涂层基材上的关键环节。
