Abstract

Posters remain a strategic medium in visual communication due to their ability to attract attention quickly and convey information efficiently in public spaces. Beyond graphic design elements such as layout, typography, and imagery, surface finishing plays a critical role in shaping visual perception, readability, and audience response. Among the most widely used finishing techniques, glossy and matte (doff) lamination exhibit distinct optical, psychological, and functional characteristics that directly influence communication effectiveness. This study aims to comparatively review glossy and matte lamination applied to posters through a narrative literature review approach. Peer-reviewed journal articles, conference proceedings, and authoritative books indexed in reputable databases including Scopus, Web of Science, IEEE Xplore, ScienceDirect, SpringerLink, and Google Scholar were systematically collected. A total of 42 relevant publications published between 2013 and 2023 were selected and thematically synthesized. The review reveals that glossy lamination enhances color vibrancy and contrast through specular reflection, thereby increasing immediate visual attraction, but often introduces glare that compromises readability and visual comfort. In contrast, matte lamination provides superior readability and reduced visual fatigue under diverse lighting conditions, conveying a professional and elegant impression, although with slightly reduced color saturation. The findings highlight that lamination selection is not absolute but context-dependent, influenced by message objectives, target audience characteristics, and installation environment. This review also identifies significant research gaps, particularly in neuro-cognitive audience response measurement, long-term durability under tropical environmental conditions, and cross-cultural perception of surface finishes. Based on these gaps, a structured research roadmap is proposed. The study contributes an evidence-based framework to support designers, printing practitioners, and visual communication scholars in making informed finishing decisions.

Abstract

Vibration monitoring is an important part of predictive maintenance to assess the mechanical condition and reliability of rotating machinery in power plants. This study aims to evaluate vibration characteristics, identify potential causes of excessive vibration and give recomendation how to reduce the excessive vibration  in the HP/IP Feedwater Pump at a Combined-Cycle Power Plant. Vibration measurements were conducted using a VIBXpert vibration analyzer at the Drive End (DE) and Non-Drive End (NDE) in horizontal, vertical, and axial directions while the pump operated at 2,970 rpm. Measured vibration velocities were evaluated against ISO 10816-3 standards, while Fast Fourier Transform (FFT) spectrum analysis and phase analysis were performed to identify dominant vibration characteristics. Motion Amplification techniques were subsequently used to visualize and validate abnormal mechanical movement. The results indicate that the NDE side exhibited the highest vibration levels, reaching 5.56 mm/s in the horizontal direction. FFT analysis shows a dominant component of 1× running-speed accompanied by several harmonics, while phase analysis shows a phase difference of 201° with a coherence value of 0.93. Motion Amplification revealed relative movement between the pump and its support structure, indicating potential structural looseness. Corrective actions—including tightening foundation bolts, repairing or replacing isolators, and re-leveling pump mounts are recommended to restore structural integrity and improve equipment reliability.
