Selection of Originals for Screen Tone Fabric Printing       In the packaging and printing industry, a variety of printing originals are often needed.Selection of Originals for Screen Tone Fabric Printing (1) Problems with the original        With the popularization of the application of three primary color fluorescent ink, the products of color step printing and screen printing on all kinds of textiles have been more and more welcomed by the majority of consumers. Selection of Originals for Screen Tone Fabric Printing         Whether it is processing and ordering in foreign trade or sales in the domestic market, traditional Chinese paintings, oil paintings and gouache paintings used to reflect the artistic beauty, curtains, sheets, bedspreads and covers used to reflect the decorative beauty, jackets, skirts, shoes, hats and cultural shirts used to reflect the beauty of clothing have successively appeared color step and screen printing produ […]

On Output Laser Phototypesetting         The operator of the laser Imagesetter can open the file in the local software to help check the loss or obvious error of the file and correct the error. Therefore, this inspection method is very careful and stable, but it will waste a lot of time. Moreover, there are some defects in this method, which can not be found in the inspection; On Output Laser Phototypesetting        This method is not available for postscript files. Although many production centers do this, it is also difficult to ensure that all required fonts exist in the workstation or rip, especially for the placed EPS files. The application file can tell us what font is used in the document, but it will not tell us what font is used in the EPS file.On Output Laser Phototypesetting        Now there is software for pre inspection before output, which can help operators overcome these problems. These program checking software check PS files and allow us to view rasterized pages on th […]

High Precision and High Density Printing         For high-precision printing, it can increase the amount of information per unit area and reduce the rose spots and moire patterns usually existing in plate making. High Precision and High Density Printing        In addition to increasing the workload and reducing the image reproduction range, it is much better than conventional printing in printing quality. In other words, through the research on high-grade printing technology, it has become the standard of printing quality in the all digital era.High Precision and High Density Printing Generally, a print with a resolution of more than 300 LPI is called a high-precision print.         The biggest difference between high-precision printing and ordinary printing lies in the difference of dot expansion rate. For example, under the accuracy of 175 LPI, the dot expansion rate of 50% is about 15%; Under 600 LPI accuracy, the expansion rate of 50% dots is close to 30%. High Precision and High D […]

Composite Process of Printing       In the packaging and printing industry, a variety of printing processes are often used.Composite Process of Printing 1. Corona treatment of plastic film surface:        Before printing and compounding, the substrate PE, PP and even aluminum foil must be subject to surface corona treatment. The purpose is to improve the firmness of printing and compounding, make it achieve the expected effect.Composite Process of Printing        And ensure that the critical surface tension during printing and compounding is greater than 38 Mn / M; For the composite film used for cooking, the thickness of the inner substrate shall be greater than 70 μ， To ensure sufficient heat sealing strength.Composite Process of Printing 2. Composite process:        The composite film can improve various characteristics of a single film and improve the protection of the contents, including moisture resistance, oil resistance, barrier, shading and air tightness. According to differen […]
