一种薄膜转移印刷的方法  Film transfer printing method 一种薄膜转移印刷的方法  Film transfer printing method
一种薄膜转移印刷的方法 Film transfer printing method
技术领域 Technical field
本发明设计一种印刷工艺，特别是一种转印膜印刷工艺。 The present invention contemplates a printing process, particularly a transfer film printing process.
技术背景 technical background
将作为中间载体的薄膜上的图文利用相应的压力转移到承印物上的印刷方法，称为转印，而根据采用的方法不同，转印可以分为：热转印，水转印，气转印，全像印刷，丝网转印或低温转印等。 The printing method on the film as the intermediate carrier is transferred to the substrate by a corresponding pressure, which is called transfer, and depending on the method used, the transfer can be divided into: thermal transfer, water transfer, gas. Transfer, hologram printing, screen transfer or low temperature transfer.
参照中国台湾专利申请案号第 095102148 号所述的转印薄膜，其是指一种于轴卷收藏时其图样不会发生相互沾黏的转印薄膜，其中包括一透明（或不透明）基底层、一离型层、一热融胶膜或感应胶膜及一图像层所组成。 Refer to Taiwan Patent Application No. 095102148 The transfer film is a transfer film which does not adhere to each other when the roll is stored, and includes a transparent (or opaque) base layer, a release layer, and a hot melt. The film or the sensing film and an image layer are composed.
前述转印膜为一种供热转印用的转印薄膜，其完成转印作业后仅需将基底层掀除即可完成热转印作业，然而此种转印却不具有保护层，完成转印作业的承印表面因无保护层作为图像层得防护，其图像层易受外在因素（如氧化，侵蚀等）而产生剥落，因此有人推出另外一种转印膜的结构，即三层或三层以上的结构，如中国专利 ZL200510027809.2 中转印膜的结构为基层、可剥离层和印刷层，其可剥离层采用有机硅系列的脱模剂，或非吸收性膜，但是，无论可剥离层采用何种物质，可剥离层的存在都会给环境带来污染并造成浪费。 The transfer film is a transfer film for heat transfer. After the transfer operation is completed, only the base layer is removed to complete the thermal transfer operation, but the transfer does not have a protective layer. The printing surface of the transfer operation is protected by the unprotected layer as the image layer, and the image layer is easily peeled off by external factors (such as oxidation, erosion, etc.), so another structure of the transfer film is introduced, that is, three layers. Or three or more layers, such as Chinese patents ZL200510027809.2 The structure of the intermediate transfer film is a base layer, a peelable layer and a printing layer, and the peelable layer is a silicone type release agent or a non-absorbent film, but the peelable layer is present regardless of the substance of the peelable layer. It will pollute the environment and cause waste.
发明内容： Summary of the invention:
本发明的目的在于克服上述两种结构转印薄膜的缺陷，可以不采用三层或多次转印膜结构，即可省去可剥离层，又令完成转印作业的承印物表面不会因无保护层而使图像层产生剥落。本发明提供了一种仅采用具有两层结构的简单转印膜的生产工艺转移印刷不规则表面产品的印刷方法。 The object of the present invention is to overcome the defects of the above two structural transfer films, and it is possible to omit the peelable layer without using a three-layer or multiple transfer film structure, and to prevent the surface of the substrate from being subjected to the transfer operation from being damaged. The image layer is peeled off without a protective layer. The present invention provides a printing method for transferring a printed irregular surface product using only a production process of a simple transfer film having a two-layer structure.
为了达到发明目的，本发明采用的技术方案为：In order to achieve the object of the invention, the technical solution adopted by the invention is:

（ 3 ）采用机组式印刷机凹版里印的方式印刷多色转印膜，即印刷油墨层 2 。 (3) Printing a multicolor transfer film, that is, printing ink layer 2, by means of printing in a gravure printing machine.
根据承印物的材质，上述的印刷膜可以涂布溶剂型背胶，并直接应用于热转印，模内注射转移的用途。背胶层可以专门针对 ABS 、 PP 、 PE 、 PS 、 PC 、 PET 、 PVC 、 EVA 等热塑型塑料。或不涂背胶，在 PU 发泡材料承印物上转移印刷精美图案。Depending on the material of the substrate, the above-mentioned printed film can be coated with a solvent-based adhesive and directly applied to thermal transfer and in-mold injection. The adhesive layer can be specifically targeted at ABS, PP, PE, Thermoplastic plastics such as PS, PC, PET, PVC, EVA. Or transfer the delicate pattern on the PU foam material substrate without applying the adhesive.
步骤二：将印刷好的转印膜在吸塑机上进行吸塑成型。Step 2: The printed transfer film is subjected to plastic forming on a blister machine.
步骤三：将吸塑成型后的转印膜套入模具型腔内壁中，注入承印材料，在材料成型的过程中完成产品的转印印刷。Step 3: The transfer film formed by the plastic molding is sleeved into the inner wall of the mold cavity, and the printing material is injected, and the transfer printing of the product is completed in the process of material forming.
采用以上工序转印得到的成品印刷图案精美，图像层不会剥落，并且由于转印膜结构简单，没有环境污染，节约了产品成本。 The finished printing pattern obtained by the above process transfer is exquisite, the image layer does not peel off, and since the transfer film has a simple structure and no environmental pollution, the product cost is saved.
