Abstract

Ink lay down sequence is a crucial aspect from technical perspective during printing which affects the print quality. The sequence of colors is very important for the print quality in the Sheet-fed Offset. This research paper delineated the variation in the print contrast of colors due to variation of different ink sequences. Although CMYK and KCMY are the standardized sequences for offset lithography but there are possibilities of printing by five different color sequences namely CMYK, MYCK, YMCK, KCMY and KYMC. To identify the effect of ink sequence in Sheet-fed Offset print quality, prepared a master and done printing in the local printing press of repute. After printing on Art and Map litho paper the result was analyzed.

Keywords

Abstract

The demand of packaging sector is growing rapidly over a period of time. Printing on flexible plastic substrates is the main substrates due to its natural nature. Along with its demand, the wastages are also main problem and its control is very important. The wastages may be in two forms i.e. Liquid wastages or solid wastages. The solid wastages play an effective role in affecting the productivity of organization. The wastages during the printing production from infeed unit to outfeed unit, including all stages are the main issue in all printing process and its finding at all stages is very important to control the wastages and improving productions. Analyzing the solid wastages at different stages guide the organization to minimize the wastages and indicates the maximum and minimum wastages during production. This research paper presents the solid wastages at different stages likes printing, inspection, lamination, slitting and trimming, during printing and machine-off operation and hence indicates at which stages the maximum wastages is occurring that can be minimized in future.
