Offset printing plates usually crack just near the gap of the press cylinder. This may happen for various reasons.
Listed below are tips to avoid such situations:
At times, the pressman may not hang the plate properly on the press. When the edges of the plates are not in direct contact with the press cylinder, the continuous movement of the press may trigger cracks in the plates.
While some machines are outfitted with an automatic plate loading system, others offer a manual system. Irrespective of whether it is manual or automatic, the pressman should ensure that the system is functioning properly. For instance, a flawed lock-up system may create pressure under the edges, thereby resulting in cracks.
Plate benders need to undergo maintenance at regular intervals. This is important because printing tasks require high levels of precision. With time, the bender may not conform to the requirements of the size and the bend, and may result in cracking.
Each plate has its own capability of how long it will last on the press. Generally, plates made from aluminum can produce hundreds of thousands of impressions; however, its thickness may differ from one another. One needs to make sure to run the plate according to the requirement and specifications. For instance, a thicker one is required to generate a hundred thousand impressions in an hour as compared to the one that would produce five thousand in an hour.
