e t T t bstract. A method of converting cyan, magenta, yellow, and black CMYK) digital values into cyan, magenta, yellow, black, light cyan, nd light magenta (CMYKLcLm) in six-color printers is proposed for roviding a better print quality with less dot visibility, high color fidelty, and smooth color transition. Based on the attribute of the depenent variable Lm and Lc to M and C, the input M a...

In this study, we focus on the design specifications of industrial inkjet printers. In these systems, the printing heads are mounted individually on a carriage. The in-plane print head rotation has been identified as one of the reasons for the ink dots misplacement. This study aims to work out the influence of the angles of CMYK printing heads on the print quality. Ultimately, some mechanical t...

The present paper studies the chromaticity gamut of multi-color printing processes. Heptatone (7color) printing – the most promising variant of multi-color printing – offers a significantly larger gamut than a conventional CMYK printing process, approaching CRT and film gamuts. The behavior of the process in the device-independent CIE-XYZ and CIE-L*u*v* colorimetric spaces is explored using the...

In prepress department RGB image has to be converted to CMYK image. To control that amount of black, cyan, magenta and yellow has to be controlled by using color separation method. Graycolor separation method is selected to control the amounts of these colors because it increase the quality of printing also. A single printer used for printing the same image on different paper also results in di...

The changes reflect our ongoing determination to offer the speediest publication times and the most accurate figure reproduction. No more paper please Our new instructions to authors are geared entirely toward online submission. Beyond saving trees, this switch to accepting only electronic manuscripts means faster processing of papers from submission to review to publication. Currently, most re...

Multicolored Jacquard artwork reproduction has been limited by the current setting of weaving machinery. Novel applications have introduced to overcome these restrictions. The subtractive cyan, magenta, yellow and black system used for color printing important in optical yarn mixing production, because a wide scope weave production is possible with small number weft yarns. Previously, channels ...

A high-resolution and angle-insensitive structural color generation platform is demonstrated based on triple-layer aluminum-silica-aluminum metamaterials supporting surface plasmon resonances tunable across the entire visible spectrum. The color performances of the fabricated aluminum metamaterials can be strongly enhanced by coating a thin transparent polymer layer on top. The results show tha...

Computer images have three or four color channels, which are grayscale images representing the intensity of colored ink or light at particular places on the screen. These are RGB (Red-Green-Blue) for work that is intended to be shown by light emitting media such as monitors or projectors, and CMYK (Cyan-Magenta-Yellow-Black) for light absorbing media such as printed paper. An alpha channel is o...
