Guy on the net is will screen tension in the net bar work, mainly used for screen printing and printing industry.Stretched mesh quality fit and unfit quality directly related to the quality of the silk screen printing, such as accuracy, image clarity, the uniformity of ink layer and sawtooth line drawing and image of turtle grain degree.Therefore, may say, tension net is an important link of silk screen printing.
Stretched involves manual tension network, mobile network and tense pneumatic tension network, etc.Manual tension net is one of the most simple, traditional methods because the operation is more troublesome and time-consuming, not easy to ensure the quality, only with a small amount of printing and accuracy is not high under the condition of use.Is currently the most used pneumatic tightening and mobile network, but it must be equipped with a dedicated mechanical tension network.
There are several ways tension net?What is the distinguishing feature of each?
Network is an essential part of making screen printing plate a tense working procedure.Tension network, is will screen under certain tension firmly fixed on the screen frame.And make the good screen has a certain tension, in order to meet the sensitizer coating and other process requirements.The size of the screen tension and tension network quality directly influences the quality of screen plate, and is a direct effect on printing quality.Color printing, the requirement of tinted screen plate per color version of the stretch mesh tension must be kept almost the same, so as to guarantee the accuracy of the overprint.Only the guy good net, to guarantee the quality of plate making and printing.Stretch network are mainly manual tension net and mechanical tension net two methods.Manual tension net is a simple and traditional method.Usually applies to wooden screen frame.This method is through the artificial with nails, wood, adhesive materials such as silk screen fixed on the wooden frame.Manual stretch mesh tension generally can meet the requirements, but uneven tension, operating more troublesome and time-consuming, stretch mesh quality difficult to guarantee.This method is more used in small amounts of printing and printing precision is not high.
Mechanical stretch mesh is the use of mechanical strength, make the screen tension, using adhesives with the net frame firmly together.Wait for after adhesive is dry, apply the net frame, with polyester film single sided pressure sensitive tape sealing side.In case of adhesive is dissolved, and make the silk screen plate look clean and tidy.All kinds of frames are available mechanical stretch mesh.Mechanical stretch mesh with uniform tension, tension network time is short, etc.Easy to learn the required tension.Suitable for high precision requirements of the plate making.
