Abstract [eng] |
Profiling (also known as tone calibration or compensation of dot gain) is the creation of each printing machine profile depending on used materials. The purpose of this process is to ensure the stable tone gradation. The profiling tests were carried out for sheetfed and heatset web offset printing machines based on ISO -12647 standard. The profiles were printed on two different types of paper having different characteristics (grammage, screen ruling). Uneven changes of raster dots in all halftones and dot gain were determined during the testing. Technological design of printing department of company was carried out, also necessary equipment and amount of employees was chose. The requirements for quality of printing plates preparation and printing processes was discussed in this work. The factors harmful for working employees were identified also the methods were provided necessary to ensure the work safety. The modernization of equipment was calculated in the economic part (costs and return on investment). |
