Potential Problems in Printing – Description of Problems and Proposed Solutions

Problem Solution
1. Too thick. 1. Add thinner.
2. Too thin. 2. Use new ink.
3. Too slow. 3. Use faster thinner.
Problem Solution
1. Poor etching. 1. Examine cliche with magnifying glass, produce new cliche as needed.
2. Etching too deep. 2. Produce new cliche with shallower etching depth.
3. Wrong cliche type. 3. Replace with correct cliche.
4. Wrong screen ruling. 4. Test new cliche with different fineness of halftone screen.
Problem Solution
1. Too soft. 1. Use harder pad.
2. Wrong shape. 2. Test different shape.
Problem Solution
1. Soiled surface. 1. Pre-clean with alcohol.
2. Not free of distortion. 2. Switch to different material.
3. Great differences in height. 3. Use pad assembly or special pad.
4. Printing in proximity to edges. 4. Jig should support substrate adjacent to edges, to prevent pad from extending over edge.
5. Very structured surface. 5. Use hard, pointed pad.
Problem Solution
1. Jig unstable. 1. Refabricate jig.
2. Fast cycle time with bulky pad. 2. Reduce speed, adjust setting to delayed cycle in front position to prevent pad from wobbling during print stroke.

Blurred print is understood as the indistinct, hazy reproduction of lines or letters. This deficiency is often confused with distortion.
