| 1. |
Stir or vibrate the ink
firstly to confirm the ink is evenly blended, so to avoid settlement,
disintegrated and bubble. |
| 2. |
Use the standard solvent recommended
by original manufacturer, and do not mix any other additive,
so that the ink would not be deteriorated. |
| 3. |
When AB type ink is used, the hardener
needs also be stirred or
shaken to even, and add the hardener
in proper ratio into ink
and stir them to be even. |
| 4. |
At each printing, the adhesion between
ink and substrate
shall be checked, so that there would not
be detachment
or destruction of finished product due to substrate
surface,
contamination or other factors between different
lot of
substrate deliveries. |

When using an ink to print, there may be problem in the printing
operation because of first time use, or due to the characteristics
of substrate or ink. IN our accumulated experience, we would present
the following frequently met problems and the solutions for your
reference:
| ● |
Bubbling: It is mainly because of the
following:
(1) Using solvent other than standard
and recommended one.
(2) Loss of flattening and bubble killing function in evaporation
or weakened and leads to bubbling.
(3) High viscosity of ink tends to generate bubble and solvent
shall be added to adjust.
(4) Lack or insufficient clearance from pattern may also cause
bubbling. |
| ● |
Cause of poor adhesion:
(1) Incorrect choice of ink.
(2) Contaminated substrate surface.
(3) Baking temperature is too low.
(4) Wrong ratio of Hardener. |
| ● |
When the clearance is
too narrow, it tends to bubble or cause orange peel condition.
It is therefore suggested that in pattern adjustment, the peeling
clearance shall be 3-5 m/m for ordinary printing and in case
of curve printing or other type of special printing, the tension
of screen shall be counted in in making proper clearance adjustment. |

It is known to the industry that the
silk screen printing has quite a lot of problems, much more
than what we have stated. If you need to discuss with us
about technical problems, please call us without hesitation. |
