Offset printing

    Demand on full color printing products is growing every year. Leaflets, booklets, Business cards, catalogues and any color printing products made by professionals improve image of the company, earn new customers and increase sales.
   Advantages of offset printing are conditioned by a number of such technological features as:
 - comparatively simple production of printing forms for machines of any type meeting all high quality requirements.
 - Possibility of high quality printing on paper with different surface structures and any density;
 - Standardization and automation of production process;
 - significant printing speed for a short period of time. Moreover the higher the circulation the more profitable the printing is. Disadvantages: offset printing requires pre-printing processing (color separation, color testing, form creation, form printing, press preparing, color balancing) that makes printing of small circulation more expensive and impossible to implement urgent orders (for example for an hour). Personalization and numbering are also impossible in this case.
   Offset printing is based on the principle of incompatibility of oil-based paints with water. First, photography of future imprint is made. Photo negative is applied to a zinc and aluminum printing plate and lightened. After volume expansion and chemical processing the plate is fixed on the drum of rotary printing press and water is supplied by shaft. When plate is painted by oil paint empty light-struck and soaked spaces repel paint while spaces which are not light-struck retain paint. Then paint form drum is transferred to rubber offset structure and from structure to paper. 
   Now offset is the most applied method of printing from the technical and technological point of view.
