Summary

This summary is machine-generated.

The substrate significantly impacts screen printing (SP) line geometry, causing broadening or undulation. This study develops a theory to predict these effects and uses the resulting patterns for microchannel fabrication.

Area of Science:

Materials Science
Fluid Dynamics
Microfabrication

Background:

Screen printing (SP) is widely used industrially, but the influence of substrates on printed line morphology is understudied.
Understanding substrate effects is crucial for controlling printed patterns in SP applications.

Purpose of the Study:

To investigate how substrate properties and printing dimensions affect screen-printed line geometry.
To develop a theoretical model for predicting line broadening and lateral undulation.
To demonstrate the application of unique screen-printed patterns in microfabrication.

Main Methods:

Systematic experimental investigation of line spreading using 1D and 2D geometrical parameters.
Development of a simple inviscid theory with perturbation analysis to model ink instability.
Derivation of a dispersion relation to predict the geometry of undulated lines.
Comparison of theoretical predictions with experimental results.

Main Results:

Screen-printed lines exhibit broadening or lateral undulation, dependent on substrate and print dimensions.
The developed inviscid theory accurately predicts the geometry of undulated lines, especially for highly liquid inks.
Unique undulated screen-printed patterns were successfully fabricated and used as photomasks.

Conclusions:

Substrate properties are a critical factor in determining the morphology of screen-printed lines.
The theoretical model provides a valuable tool for predicting and controlling SP line geometry.
The study demonstrates a novel method for fabricating microchannels using substrate-induced undulated patterns.
