Tubular Picket Ornamental Fence A tubular picket fence is a type of fencing that is made up of vertical pickets or posts that are connected by horizontal rails. The pickets are typically made from tubular steel or aluminum, which makes them durable and resistant to rust and corrosion. The fence is designed to provide a secure and attractive barrier around a property, while also allowing for visibility and airflow.

Ink unevenness
There is a periodical change of ink on the printed matter. Exclusion methods include: correcting the roundness of the plate cylinder, adjusting the squeegee angle, pressure, or replacing a new squeegee.
Imprint hairiness
The image of the printed matter is layered and leveled, and the burr phenomenon appears on the edge of the graphic. Exclusion methods include removing static electricity from the substrate surface, adding polar solvents to the ink, appropriately increasing the printing pressure, and adjusting the position of the doctor blade.
Blocked version
The phenomenon that the ink dries in the printing plate's cell, or the plate's cell is stuffed with paper and paper powder, is called blocking plate. Exclusion methods include: increase the content of the solvent in the ink, reduce the drying speed of the ink, and use high-surface-strength paper printing.
Ink overflow
The phenomenon of spots appeared in the printed part of the print. Excluded methods are: Add hard varnish, increase the viscosity of the ink. Adjust the angle of the squeegee to increase the printing speed, and replace the deep-mesh point printing plate with a shallow mesh printing plate.
Scratches
The print has traces of a squeegee. Excluded methods are: Printing with clean ink mixed with no foreign matter. Adjust ink viscosity, dryness, and adhesion. Use a good squeegee to adjust the angle between the squeegee and the plate.
Pigment precipitation
The phenomenon of lightness on prints has become lighter. Excluded methods are: Use of ink with good dispersion and stable performance. Add anti-agglomeration, anti-precipitation additives to the ink. Roll well and mix the ink in the ink tank.
Sticky
There is an ink stain on the printed matter. Excluded methods are: Select ink printing with fast evaporation speed, increase drying temperature or appropriately reduce printing speed.
Ink shedding
The ink printed on the plastic film is poor in adhesiveness and rubs off by hand or mechanical force. Excluded methods are: to prevent the plastic film from getting wet, choose printing ink with good affinity with the plastic film, and re-surface the plastic film to increase the surface tension.
Tubular picket fences come in a variety of styles and designs, including traditional, contemporary, and ornamental. They can be customized to fit any landscape or architectural style, and can be painted or powder-coated in a range of colors to match the surrounding environment.
One of the main advantages of a tubular picket fence is its strength and durability. Tubular picket fences are commonly used in residential, commercial, and industrial settings. They are often used to enclose swimming pools, gardens, and outdoor areas, and can also be used for security and privacy purposes.
