IMD(In-Mold Decoration) Technology Screen Printing Inks:
IMD technology is applied to different products, and there are differences in material selection, technical processes, etc. For example, printing substrates usually include PET, PC, PC/acrylic composite sheets, PP and other materials; ink models involve halogen and halogen-free, Weather-resistant and non-weather-resistant, high stretch and low stretch options; injection molding materials include ABS, PC, ABS & PC, TPU, PS, acrylic and other options; injection molding processes include front injection molding, reverse injection molding, front and back injection molding at the same time, etc.
Today I want to discuss with you the common problems and solutions during the manufacturing process of IMD products that use PET sheets as the printing substrate and ABS as the injection molding material. They are usually used in the home appliance panel industry.
Before talking about this topic, let us first understand the two main materials of IMD ink and PET sheet, because most common problems that occur during the manufacturing process of IMD products are closely related to these two.

IMD Solvent Based Ink
IMD UV Ink
Conclusion:
Generally speaking, solvent-based inks have more advantages than UV inks in terms of adhesion, masking, stretch, metallic color gloss, and adhesive bonding strength. Therefore, the applicability of solvent-based inks in IMD products will be more widespread.
Since UV ink has the characteristics of non-blocking and strong three-dimensional effect, it has certain advantages when applied to the printing of fine dots, drawing and other patterns. However, we should pay attention to the undesirable phenomenon of yellowing of PET sheets after repeated UV irradiation.
