Cause |
Solution |
| Ink |
Ink is wrong type. |
Perform ink tests and try various different types of inks. |
| Wrong hardener or lack of hardener was used with a two-component ink. |
Mix ink with correct hardener. |
| Incorrect mixing ratio was used. |
Use correct ratio of ink to hardener by weight.
|
Material (substrate)
dyne |
Surface of part is contaminated with mold release. |
Clean part prior to printing. |
| Surface tension of part is too low. Common substrates with this trait are polypropylene and acetal. |
Pretreat parts to increase surface tension to at least 44 dyne (use TTA#T500xx; xx=level of solution). |
| Curing |
Not enough heat applied to the part. |
Use a higher temperature or heat for a longer time. |
| Not enough curing time used. |
Part must sit for one to five days before fully cured. |
| Too much heat was used. Plastisol or flame retardant is bleeding through. |
Use a lower temperature and heat for a longer time. |
