The In-Mold Roller is a revolutionary printing process by which objects are 3D decorated. Products decorated by In-Mold Roller are waterproof and protected from fading. What’s more, these kinds of decorations strongly increase the beauty, desirability and value of the objects. The In-Mold Roller is now using either of gravure printing and screen printing to print PET film. However, there are some problems with these two techniques. This research is to investigate potential usages of combining In-Mold Roller with digital UV inkjet printing in 3D decoration, e.g. in personalized printing services. Study results found that when the coverage and the resolution of inkjet printing become higher, the SIDs will become higher as well. When transferred to ABS, SIDs in each combination will increase. Each combination of inkjet conditions, with the isolation of white ink, color differences are less variant. TVIs of white ink decrease 30% to 40% halftone and display in “M” type. In print contrast, C and K colors of each combination are better than M and Y colors. After transferred into print contrast, each combination of PC will be higher about 2 to5. When transferred to ABS, color variances of each combination are not huge, and color differences are about 3to5.
The In-Mold Roller is a revolutionary printing process by which objects are 3D decorated. The products decorated by In-Mold Roller are protected from water and fading. These kinds of decorations strongly increase the beauty, desirability and value of the objects. The In-Mold Roller is now using either of gravure printing and screen printing to print PET film. However, there are some problems with these two techniques. This research is to investigate the potential use of combining In-Mold Roller with digital inkjet printing in 3D decoration, e.g. in personalized printing services. The study results found show that digital inkjet printing to the PET film and then transfer to the ABS, the solid ink densities (SIDs) of primaries would increase. The tone values increases (TVIs) from highlight and middle (around 0~60%) were generally higher than those in shadows. The shapes and sizes of color gamut were also varied according to different kinds of digital UV inkjet printing processes. Moreover, after transferred, the color gamut became smaller.
IMR can print out excellent textures and effects on irregular surfaces. Many products decorated by IMR are protected from water and fading, and these kinds of decorations strongly increase beauty, desirability and value of the objects. Therefore, this research is to investigate the potential use of combining IMR with UV inkjet printing and to compare color variance of IMR between PET coated and uncoated white ink. Study results show that the SIDs of PET with white ink is higher about 0.15 to 0.2 than the PET without white ink. The SIDs of PET without white ink will decrease and the SIDs of the PET with white ink will increase when transferred. The PC of PET without white ink is about 10 to 15 higher than the PET with white ink. After transferred, the Color Gamut became smaller than before. Especially for the PET without white ink, its color differences △E can reach 40. In addition, the color gamut became smaller when transferred.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
