Tensioning Fabric - Staged Method on Pneumatic Stretching System
Step-by-step instructions on tensioning mesh on a pneumatic stretching system using the staged tensioning method.
Effects of Drying Temperature on Screen Tension Part 2
This study looks at the effects of drying temperature on screen tension. The results show that drying at higher temperatures created lower tensions on screens before they were printed.
Drying Blockout Retouching
Indirect photostencil films are dried after mounting. Direct/indirect stencils need two drying stages - after lamination and after washout. To avoid dimensional changes, edge lifting, edge shrinkage and reduction in adhesion, stencils should be dried with cold air; i.e., at ambient temperatures.
Properties of Epoxy Systems
Whatever your experience with epoxy screen printing inks, the following information will, hopefully, help you to determine the proper epoxy for your next requirement. Epoxies, when properly mixed and cured, have excellent resistant properties against many acids, oils, solvents, detergents, …
Screen Making Basics Stencil Selection & Application
Preparing the screen is the first step in the screen printing process and is probably the most important one. We can’t expect to achieve a good print result when using a screen of poor quality. The objective in any printing process is to reproduce the original artwork as exactly as possible.
Screen Printing Inks and Plastic Substrates
Much of the screen printing industry’s growth is due to the introduction and increased use of new plastic substrates coupled to the development of compatible ink systems. Since the printer’s end-product consists basically of ink and substrates, ink and plastic manufacturers have collaborated closely …
The Squeegee Our Basic Tool
This paper is a review of how the past several years of technological and chemical changes in screen printing have affected the squeegee — the one tool which has remained relatively unchanged through the years. We have succeeded in fine tuning the stencil materials to where we can now reproduce an …
Value A Concept in Screen Quality Evaluation
Evaluating the quality of a direct-emulsion stencil before it is on press is a difficult task. Pinholes and edge defects might be uncovered with illumination and magnification, but overall stencil quality and flatness are impossible to measure. After many months of research, a test has been established …
Printing Inks and Quality Principles of Ink Selection
No other printing method is as versatile with regard to printing substrates and color characteristics as screen-printing. This versatility demands a correspondingly broad spectrum of different screen printing inks.
The Rz Value A Concept in Screen Quality Evaluation
Evaluating the quality of a direct-emulsion stencil before it is on press is a difficult task. Pinholes and edge defects might be uncovered with illumination and magnification, but overall stencil quality and flatness are impossible to measure. After many months of research, …
