Color printing proceeds with multiple halftone separations overlay. Because of separation overlay misalignment in printing, the percentage of different primary color combination may vary and it will result in color shift. In traditional printing procedure with AM halftone, every separation has different screening angle to make the superposition pattern in a random style, which will reduce the c...

Subwavelength structural color filtering and printing technologies employing plasmonic nanostructures have recently been recognized as an important and beneficial complement to the traditional colorant-based pigmentation. However, the color saturation, brightness and incident angle tolerance of structural color printing need to be improved to meet the application requirement. Here we demonstrat...

We report a structural color printing platform based on aluminum plasmonic metamaterials supporting near perfect light absorption and narrow-band spectral response tunable across the visible spectrum to realize high-resolution, angle-insensitive color printing with high color purity and saturation. Additionally, the fabricated metamaterials can be protected by a transparent polymer thin layer f...

Thermochromic printing inks could be security inks which respond to the color change when are being exposed to different temperatures. These inks with unusual chemical and physical specific characteristics are mostly produced for flexographic, screen and rotogravure printing systems under the supervision of skilled technical experts and with precise security controls. Since flexographic thermoc...

Electrophotographic printers are required to provide photograph quality printing with the rapid implementation of color in an office environment and meet the needs for POD*1). The printing quality of conventional color electrophotographic printers is no longer capable of adequately satisfying the needs of customers. Furthermore, printing systems with a high resolution are used in the pre-press ...

Structural color printing based on all-aluminum plasmonic V-groove metasurfaces is demonstrated under both bright field and dark field illumination conditions. A broad visible color range is realized with the plasmonic V-groove arrays etched on an aluminum surface by simply varying the groove depth while keeping the groove period as a constant. Polarization dependent structural color printing i...

This paper deals with study of color deviation caused due to changing screen angle combinations in process color lithographic offset printing. The printing test chart comprises of conventional and customized angles for process colors.

Managing and controlling color, from scanner to monitor to output devices, are serious issues for the printing and imaging industries. Accurate color control is vital for predictable quality of final product, whether printed or displayed. Costs of controlling color are significant. Printing has become much more science than art and any company, especially those involved in printing and other me...
