Case Making Fold Impression

Yes, it is possible to get an impression of a folded sheet after case making sheets are kept under pressure in a machine. This is because the pressure of the machine can cause the ink on the sheet to transfer to the adjacent sheet, even if they are folded. The amount of impression that is visible will depend on the amount of pressure that is applied, the type of ink that is used, and the thickness of the paper.

To prevent this from happening, you can try the following:

  • Ensure sheets are properly put in case making rollers. Do not put directly under pressure machine.
  • Use a lower pressure setting on the machine.
  • Use a type of ink that is less likely to transfer.
  • Fold the sheets more tightly so that there is less surface area for the ink to transfer to.
  • If possible, avoid keeping the sheets under pressure for long periods of time.

If you do get an impression of a folded sheet, you can try to remove it by using a mild solvent or by gently rubbing the area with a damp cloth. However, it is important to note that this may damage the paper.

Here are some additional tips to help prevent impression from appearing on folded sheets:

  • Use high-quality inks and papers.
  • Make sure that the case making machine is properly calibrated.
  • Inspect folded sheets carefully before using them.

I hope this helps!
