Determining Differences In Quality Between The Gravure And Flexographic Process On Films, Pete Welther
Paper Engineering Senior Theses
Quality is the goal of every printing company. Every day printing companies spend money trying to find ways to improve the quality of their product. Type of paper, ink, and even the types of printing processes are all characteristics looked at when determining the quality of a printed product.
In today's printing industry, there are two printing processes that have arguably jumped to the front in terms of the highest quality printing ability. The flexographic process and the gravure process have both risen to meet the standards of high quality. The gravure process has always been at the top. For …

Strengthening Of Corrugated Boards By Chemical Impregnation, Rajesh Premnarayansingh
Masters Theses
Linerboards are used for making corrugated boards. The paperboards can be strengthened by adding strength additives at the wet-end of the paper machine and also by sizing them. Impregnation is another effective approach of strengthening the paperboards, mostly offline. The aim of the thesis is to evaluate the performance of the modified Dixon coater and check the operating conditions with various chemicals used for impregnating 42 lb/1000 sq.ft grammage linerboard.
The major conclusions of the research were that the edge compression strength increases markedly validating the usage of impregnation for linerboards. Also, the stiffness of linerboard increases and the voids …
