"Printer has excessive plate wear"





February 16, 2010

Hi I was wondering if any readers can shed any light on our problem when using Idem carbonless reels as we seem to have excessive plate wear as well as problems regarding wear in both the perf blades and sprockets although when using Reacto none of these problems occurred.Any help with this would be appreciated.

From what I understand you have plate wear problems when using different papers. That I could not explain. However, in terms of wear I may have a solution. Have you ever heard of cryogenic treatment? Parts made of steel will benefit the most from cryogenic treatment. We have treated many blades and plates for the printing industry with great success.

Cryogenic treatment transforms steels in three ways.
1. Wear resistance improvements resulting in a longer overall lifetime (usually 100% to 200% increase in life)
2. Crystalline structure transformation resulting in a more durable part. Hardness will not increased but voids and imperfections in the molecular structure will be removed.
3. Parts will undergo stress relief to remove stress lines that will eventually result in fatigue failure.

If you have any questions, let me know.

The problem might not be wear, or at least only wear. You might be seeing some corrosion of the steel surface as you change materials. A PVD coating such as TiN or ZrN would provide both wear and corrosion protection.

Many thanks for your replies however the problem seems to be that when using a resin based carbonless paper we don't have a problem however when we use Idem carbonless which is clay based the problem arises pointing towards an abrasion from the clay coating?Any further opinions much appreciated.
