1. Adjust the structure of newspaper printing

      At present, China’s newspaper printing is almost dominated by offset printing. Offset printing is used all over the world, regardless of the size and printing volume. Europe and North America broke the single pattern of offset printing in the 1990s. We should also reasonably choose the printing method according to the specific situation.Application of Flexographic Printing in Newspaper Advertising

2. High paper loss rate and waste rate are the prominent problems of offset printing

      In offset printing, the control of ink balance is an important problem, and the realization of ink balance in offset printing needs a process. Generally, it takes about 15-30 minutes to adjust the machine and try printing from Startup to entering the stable working state, which will inevitably increase the paper loss rate. Application of Flexographic Printing in Newspaper Advertising 

      In the offset printing process, there are many factors affecting the ink balance, and most of these factors change.Application of Flexographic Printing in Newspaper Advertising

        Even under normal printing conditions, waste products will appear due to the change of some conditions. For example, the paper loss rate of sheet fed four-color offset press is generally as high as 7% – 15%, and the paper loss rate of web offset press is higher than that of sheet fed offset press. Therefore, in terms of economy, offset printing is not the best.Application of Flexographic Printing in Newspaper Advertising 

3. Offset newspaper does not have much advantage in print quality

        The high quality of offset printing is based on many conditions. If the requirements for the surface properties of the printing materials are high, fine prints can be printed only when coated paper with high price and good quality is used for printing. Application of Flexographic Printing in Newspaper Advertising

        Printing on newsprint is prone to the following problems:  offset printing uses fountain solution, while newsprint has strong water absorption, and the whiteness of the paper will decrease after water absorption; Application of Flexographic Printing in Newspaper Advertising

          Because the surface of newsprint is very rough, it will affect the clarity of graphics and text;  In the printing process, it is easy to be affected by external factors, the stability of printing quality is poor, and it is easy to have faults such as uneven ink color and dim color.Application of Flexographic Printing in Newspaper Advertising
