Solution |
| Ink |
Ink is too thick (poor line definition or broken letters). |
Adjust viscosity of ink by adding thinner. |
| Ink is too thin (blurred image or balloon characters). |
Remix ink. |
| Pad |
Ink is not releasing from pad. |
See "pad is not releasing whole print onto part". |
| Pad is too soft. |
Use harder pad. |
| Pad is too steep for part angle (round). |
Use larger or flatter pad. |
| Cliché (plate) |
Cliche is etched too deep. |
Make new cliché with proper etch depth. |
| Screened cliché etch has saw-toothed edges. |
Make new cliché with solid etch or see "screened dots are visible". |
| Artwork is of poor quality. |
Clean up artwork. |
| Cliché etching is of poor quality. |
Inspect cliché with a magnifying glass. Remake cliché if necessary. |
| Material (substrate) |
Part surface is dirty or contaminated. |
Clean part and/or wear gloves. |
| Surface of the part is textured. |
Use a hard pad with a sherp angle. |
| Printing surface of the part is not flat; pad and ink are slipping. |
1. Try to make surface flat.
2. Dry the ink as much as possible on the pad before transferring image to part.
3. Use larger pad on round part.
4. Use hollow pad to lessen part pressure. |

Fixture is unstable. |
Remake holding fixture. |
| Machine cycle is too fast for large, soft pad; wobbling occurs. |
1. Slow down machine.
2. Delay pad down-stroke.
3. Use smaller and/or harder pad. |
| Pad pressure is excessive. Cliché is not being doctored cleanly. |
Decrease pad pressure. Re-hone or replace doctor blade. |
