Screen printing mesh type, material, size, color, mesh guide.Screen printing mesh cloth is used in the general name of the screen printing network. From the woven material is divided into metal screen printing mesh and chemical fiber screen printing mesh. Metals are generally made of stainless steel, which has high tensile strength, low elongation characteristics, but the price is very expensive, the application is not very common.
Screen printing mesh cloth is used in the general name of the screen printing mesh fabric. From the woven material is divided into metal screen printing mesh and chemical fiber screen printing mesh. Metals are generally made of stainless steel, which has high tensile strength, low elongation characteristics, but the price is very expensive, the application is not very common. Its chemical fiber silkscreen mesh general points polyester material and nylon material. The difference between the two is that the polyester material screen printing its elongation is low, the mesh is more difficult to deformation, high printing accuracy. The nylon material has its flexibility, can be applied to non-planar printing materials, and its wear-resistant properties. And then from the weaving process can be divided into plain weave and twill mesh, plain twill relative twill has its printing precision, while twill mesh has its high tensile characteristics.
Screen printing mesh fabric types
In general, the screen printing is supported by the net cloth, the main function is to form a version of the control of ink and ink, the main screen printing mesh cloth used are:
Tulip screen printing mesh fabric: Has a larger stretch and recovery, is multifilament weaving, so the surface roughness of the film easy to attach, but different diameter, printing instability and mesh openings, elasticity is not strong, poor ink permeability If the version of renewable, the emulsion film is not easy to remove.
Nylon screen printing mesh fabric: woven into monofilament or multifilament for plate making, printing has a good effect, can be woven into fine mesh, open degree stability, good strength, good response, and the ink through the Excellent, suitable for large quantities of printing, but not color printing precision, multifilament nylon mesh for cloth printing.
Polyester screen printing Mesh fabric: Made of monofilament more flexible, small mesh can be woven into more than 400 to 500 lines, but more than 380 lines its weaving often adopted Aya weaving, suitable for a large number of fine color printing.
Plating screen printing Mesh fabric: Trondone and metal cheaper, good recovery, high resistance and precision, plating network is Trinidad on a layer of nickel-plated anti-static can be made. Electroplating nets through the network stability and stability, but poor light drying web should be increased by 50% of the printing time.
Stainless steel screen printing mesh fabric: the use of electronic precision printing, can make a large degree of openings Mesh, but easy to generate permanent extension, and Zhang is not easy to expensive, degreasing should not be too hard to use Grit or brush, copy Time should be longer. Cylinder Press rotary drum network, then the current printing method for printing and dyeing the fastest screen.
Metal screen printing mesh fabric: Due to the high-precision printing, the mesh used in high-mesh cable, weaving technology is not easy to achieve, so the use of metal foil coated photosensitive agent or dry film, after imaging corrosion made of plate pattern or Laser cutting machine directly into the pattern, mostly used in the need for high precision IC printing.
UV Screen Printing Mesh cloth: It is a pressed mesh that is suitable for UV ink printing. The thickness of the mesh is thinner but the warp and weft threads are fixed. The amount of ink is about 30 ~ 50% less than that of ordinary mesh. Printing Ink thin for UV light fast drying.
Alpha Screen Printing Mesh cloth: its different from the general network of longitude and latitude woven interweave method, but the latitude and longitude lines cast and formed a flat metal mesh, with excellent dimensional safety, and high-precision smoothness can reduce the damage of the printed material, it is suitable Do film printing, and multi-layer circuit printing, high-density thick film IC printing.
Carbon fiber screen printing mesh fabric: is to eliminate static problems and improve mesh, its structure is in every part of the weft yarn, that is, a carbon fiber gauze spacing of the mesh, can rule out the generation of static electricity.
Screen printing mesh weaving method:
In general there are plain weave, weaving yarns, weft yarns weaving, weft yarns weaving, etc. Weaving and weaving are more commonly used in plain weaving. Generally, the weaving of woven fabrics is more uniform, but the weaving cost of weaving yarns is more low.
Screen printing mesh fabric properties:
Mesh: Refers to how many lines are in each centimeter or inch. Inch = 2.54 ㎝
Mesh openings: refers to the warp and weft enclosed by the square hole unit, the opening diameter of the amount of ink and quality requirements have a great impact, usually net openings, pigment particles must be more than three times the fineness (raw materials Particles about 4 ~ 10μ), in order to make the ink is very smooth printed by the mesh opening, so the mesh mesh less opening the greater the contrary, the smaller. The thicker the wire, the smaller the opening. The minimum diameter of the general mesh about 30μ, the minimum diameter of the special mesh 18μ. Thin wire diameter, large openings can reproduce the fine pattern.
Screen printing mesh Material types:
Monofilament: refers to the screen printing mesh each silk, woven from a single cable.
Multifilament: refers to the screen printing mesh fabric each line, is composed of multiple filament twist woven. (Printed dyeing with multi-filament sometimes have better results)
Screen printing mesh fabric material types of code:
NO refers to the latitude and longitude for the monofilament made of mesh.
TNP refers to the warp and weft are woven into the mesh.
TP refers to the warp monofilament, weft with multifilament woven into the mesh.
Mesh diameter of the thickness: the thickness of the network, the thickness of the ink after printing has a decisive impact, usually the lower the mesh mesh, the diameter of its network will be more coarse, the greater the degree of network cloth, and vice versa fine.
Mesh thickness of the said:
S (Small) that thin data.
M (Medium) Indicates medium grade material.
T (Thick) indicates a thick material.
HD (Heavy duty) refers to the thick material.
screen printing mesh fabric size information
Screen printing mesh fabric size: Mesh is made by the warp and weft, the warp can be wireless long, weft width is generally divided into 44 ", 54", 64 ", 66", 78 ", visual machine frame size selection Appropriate mesh to avoid waste mesh.
Screen printing mesh fabric color: white, yellow, orange red, black, and black is not used in the current screen, colored mesh main purpose is to prevent the generation of chaos reflections, the color of the more those who can avoid the random reflection, but the relative The longer the exposure time, the white mesh is not suitable for making fine patterns.
