Mesh Count of the Silk Screen Printing Mesh fabric refers to how many holes per inch, the measuring unit is mesh/inch. The Mesh Count tells the density between the adjacent two yarns. The higher mesh count, the higher density, the finer mesh opening, and lower deposit ink volume, on the other hand, the lower mesh count, the lower density, the bigger mesh opening, and higher deposit ink volume. Mesh count chose should be according to the printing precision of the printed objects.

The thread (yarn) diameter is the diameter of the monofilament yarn who weaving the silk screen printing mesh. Usually measured by um. The thinner thread diameter, the larger mesh opening, but the worse corrosion resistance against corrosive solvents, and the worse wear resistance of the ink and squeegee. Thicker thread diameter increases the print durability of the screen printing mesh.
The thickness of the Silk Screen Printing Mesh refers to the distance between the two surfaces of the mesh. Normally measured by mm or um. The thickness value should be measured when mesh still without tension, it depends on the yarn diameter and weaving type and related to the deposit ink volume.
Mesh opening of Silk Screen Printing Mesh is the parameter to show the width of each square hole on the fabric. It makes great impact on the printing precision of the printed images and characters. Measure unit is mm or um. Usually, the mesh opening should be three times of solid ink particles.
Open area or effective filtering area, or hole area percentage, refers to the percentage of hole area in a unit area of the screen mesh. Measure unit is %.
The theoretical ink volume is the maximum ink volume required to fill the opening of the screen. It’s measured in cubic centimeters per square meter (cm3/m2). The theoretical ink volume just to estimate the ink consumption simply, the actual ink consumption and ink thickness, should be calculated based on the print medium and ink conditions.
The percentage of solvent diluent, specific gravity, solid content, viscosity, and screen mesh weave type, screen type, squeegee hardness, squeegee shape, printing pressure, and angle, mesh opening size, screen tension, printing machine type, etc. all will affect the ink volume consumption.
