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.

The stochastic screen has traditionally been used to preserve images with fine features as well as to reduce printing Moiré of images that contain input periodic structures. However, the stochastic screen also has experienced more difficulty in maintaining color stability in long press runs. Kodak, using its multilevel printing architecture, has created a new stochastic screening technology, wi...

Printing applications using classical halftoning need to resample the original image to a screen lattice. This resampling can cause undesirable moiré artifacts in the screened image. Some printing techniques, e.g., gravure printing, are highly susceptible to moiré, not only because of the low resolution screen lattices they employ but also because the degree of freedom in constructing halftone ...

Introduction: With traditional radio frequency (RF) circuits, planar inductors lie on their host substrate and, as a result, suffer from the unwanted effects of low unloaded Q-factors and low first self-resonant frequencies. The former restricts the use of these inductors to poor selectivity and lossy applications, while the latter presents a limitation on the useful bandwidth of operation. Thi...

The presence of formaldehyde in indoor air samples has been detected in five screen printing facilities of Novi Sad, Serbia. Air was sampled five times during one working week for each screen printing facility. The sampling was conducted continuously during 4 hours. The concentrations of formaldehyde were determined by UV-VIS spectrometry at 580 nm. The average concentrations of formaldehyde we...

Screen printing has been the dominant method of thick film deposition because of its low cost. Many experiments in industry have been done and many models of the printing process have been developed since the 1960’s. With a growing need for denser packaging and a drive for higher pin count, screen printing has been refined to yield high resolution prints. However, fine line printing is still co...

Low Temperature Co-fired Ceramic (LTCC) technology has attracted much attention for high frequency applications due to the advantages in preparing 3D circuits within a ceramic block that enables burying of passive elements; resistor, inductor and capacitor (Jantunen et al., 2003). This technology also offers another advantages such as low fabrication cost due to parallel process, utilizing high...
