Technology mechanical point-shock engraving on photo printer for printing on products is particularly popular among specialists designers because the entire process of creating images and computer training to the engraving is very creative and at the same time allows you to make adjustments to the customer at any stage without much effort or loss of quality and time. To solve this problem it is necessary to analyze the causes of the marriage; determine the types of marriage by using technology of printing on the surface of the product mechanical point-impact photo printer and suggest methods to eliminate it.

We obtained the solution of the optimization problem for the step-parallel beam with constant width of the cross-section. The problem was solved by minimizing the strain energy while the volume of beam is constant. The solution was made for the case of simple support at the ends and evenly distributed along the length load. We introduced the parameter α, which is the ratio of height of the average part to a height of side parts. The optimal value of α was found. At this value the stiffness of the beam is maximum at constant volume. The obtained beam of maximum stiffness is not equal strength.

We solved the problem of optimizing the gable beam by minimizing the strain energy at constant volume. The problem reduced to an integral equation for determining the optimum angle of the beam. This equation was solved numerically by the method of bisection. Integral was calculated using the method of trapezoids. Solution was made in software package Matlab. The optimum angle depends on the width of the cross section b, and the volume of the beam. It was found that with increasing of width of the cross section the optimum tilt angle decreases. Also the volume increases by increasing the width of the beam.

This article related to the technological problem. Books and manuscripts are subjected to natural aging due to the fragility of the raw materials, the deterioration of the conditions of storage, as well as losses of fragments due to repeated or careless operation. Therefore, for libraries, archives and museums is particularly important in matters of preservation of documents not only the process of conservation, but the recovery of the lost fragments.
