Elastic Plates

The second part of the strain, which recovered over time (15 min.) Characterizes the elastic deformation of the plate or Dekel. And the third component of the compressive strain, which does not recovered after the load is resilience plate or Dekel. The values of these components can be expressed as a fraction of 100% of the total strain compression are important characteristics, almost determining the behavior of Dekel in the printing process. Therefore, these figures need to pay attention to how the procurement materials, and in the preparation of these offset Dekel. High proportion of elastic and elastic- low percentage of residual strain in a total compressive strain guarantee a low degree of burnishing, high run length Dekel and its resistance to shock loads. If the elastic strain in the development of plates are trying to get as much as possible, and the residual – as low as possible, the value of elastic deformation must be held within 8-12% of the total, as with its share of less than 8%, the plates have excess rigidity, and for more than 12%, cause problems in the process of burnishing Dekel, ie significantly increases the time it burnishing. The best modern plates have the following relation share the strain components: Elastic – 75% elastic – 10% residual – 15%. Such a ratio is an indicator of high quality rubber plates and pod materials. To ensure quality printing, you must comply with established passport machine diameter ratio cylinders, with the form and the printing cylinder with a deckle under pressure.
