Common Causes of Pinholing in Flexo Prints
If you frequently use your flexographic machine in Scurry, Texas, there may come a time when you notice that its substrate no longer print fully. This printing defect is common in flexo prints, and it is called pinholing.
Here are some of the common causes of pinholing and how you can resolve it:
- Poor Ink Transfer
When your ink is not fully wetting out on the substrate, then pinholing occurs. To troubleshoot, pay attention to temperature, humidity, and air circulation. These factors should complement well with your choice of ink so that the latter does not dry out quickly.
- Irregular or Damaged Substrate Surface
No ink transfer will occur if the substrate is polluted or pitted. If this is the cause of the pinholing of your flexographic equipment in Scurry, Texas, then you should be able to solve this by changing your substrate.
- High Ink Viscosity
Pay attention to the viscosity of the ink. Inks with higher viscosity will affect the image transfer to the substrate. You can avoid using viscous inks or simply use additives to adjust the ink’s viscosity. The ink should be fluid enough for proper image transfer.
