Manufacturer analysis compared the advantages and disadvantages of offset and screen printing
Screen printing factory is introduced, in the printing industry, we often hear someone mention of offset printing and screen printing, offset printing and screen printing each have different characteristics, many people will ask, so what's the difference between the two? What kind of printing effect will be better? To these questions, screen printing press small make up will give you a brief introduction to the below: <> 1, lithography, <> Lithography is a kind of offset printing, offset printing is more widely used printing today, it is the ideal way to half black color image replication. In offset printing. By local and comfortable in the same three-dimensional graphic department, an essential feature is the offset printing, graphic local can consciously adsorption inks, rather than by local crowd out ink, the key of this technique is to use the natural characteristics of metal material, application of flat printed copy of the image has medium rich, clear, dot some layers, color coordination, real natural strengths. <> Disadvantages: screen printing vendors would tell you, the craft is more complex, difficult skill operation, high technical requirements for the operators, such as: operators to handle plate, paper, ink and printing environment, if slightly do not pay attention to, may cause the material waste. <> 2, the screen printing <> In this way of printing, plate is flat, printing was done under the embossing roller rotation. In stamping process, the movement direction of the plate roll and Jane are the same, as the embossing roller roller transfer ink through the mesh on the plate transferred to the substrates. Plate and scraper varies according to the shape of the substrates (curve type, arc type, shape) of the front plate and the moving direction of the substrates is the same, rubber scraper is fixed. This process can be used to printing tin plate and spherical body, that is to say, this is a way of surface printing. <> Screen printing effect is better, easy to realize mechanization. Disadvantages: screen printing screen printing cost is higher. <> Screen printing vendors would prompt, in our life, is often combine two kinds of printing technology, printing tend to be more perfect, printing technology in our country, has achieved the combination of offset printing and screen printing, and good results have been achieved. <>
