     The preparation of materials for print is one of the most fundamental steps in production because it is exactly what determines the quality of the book as the final product.
One of the milestones of the electronic editing system, which is the responsibility of the Production Preparation Department, is the making of a test print to make sure that the imposition is correct. Imposition of print jobs is done using Heidelberg Signastation and Metadimension software running on dual-core computers. 

     Imposition prints are made using a fast DocuColor 252 colour printer. The guaranteed high quality of plots provides a practical representation of offset printing. For the preparation of imposition prints, a HP 5500 wide format plotter is also used.
Before releasing them for printing, the prints are sent to the customer for final approval. Thus, any errors can still be corrected. 
Most printing houses use wide format inkjet plotters for this purpose. It is not the best solution because it takes as many as twelve minutes to print one sheet using such a plotter, which, combined with the processing time of the sheet, i.e. its gluing, cutting, folding and stitching, makes up, on average, 20 minutes. 
Following the implementation by OZGraf S.A. of a quality laser printer with colour management software, the time that was needed so far to prepare imposition prints can now be reduced by even several times.  

 

     With competition as high as it is in the printing market, the equipment helps OZGraf S.A. turn around jobs quicker, without delays caused by the low efficiency of wide format plotters that have been used to date.
To make sure that the colouring is correct, certified colour proofs are produced using the GMG system, which comprises an Epson 4800 printer, a spectrophotometer and relevant software. Proofs are printed on standardised GMG paper and always provided with our ISO-compliant colour compatibility certificate.
The final product of preparation for printing is offset plates, which are exposed using a fast thermal imagesetter. The state-of-the-art CTP Kodak Magnus 800 Quantum imagesetter and the Kodak Mercury HD developing machine provide excellent efficiency while maintaining constant quality. This is a technology that ensures the integrity of image exposure throughout the entire process, starting from the original file to the printing machine, regardless of variables such as laser power, emulsion sensitivity or physical properties of the plates.

To stay all the time in touch with our customers, we use the Kodak Insite Prepress Portal, a modern online system to transmit, accept and approve printwork for printing. It ensures quick, safe and user-friendly  access to our company’s workflow system. It enables our customers to access their jobs on the FTP server from every place and every time. Each customer can access their directory round the clock.
