WL-350S Two-Color UV Roll-to-Roll Screen Printing Machine

Two-color screen printing in one roll-fed line

The WL-350S brings two screen-printing stations into one roll-to-roll line for label production. The two print heads can be controlled independently, allowing the printing sequence to be configured around a two-color job. The listed equipment includes unwinding, two feeding units, two UV drying units and rewinding.

The maximum web width is 350 mm and the maximum print area is 330 × 450 mm. A 550 × 700 mm screen frame and a maximum feed length of 450 mm define the working format for artwork preparation and job planning.

Features for two-color label production

• Two printing stations: print two colors within one coordinated line, with independent control of the two heads.
• UV drying between process stages: the configuration includes two UV drying units, each fitted with two lamps.
• Coordinated web transport: the catalogue describes speed-matched unwinding, feeding and rewinding to support material movement through the line.
• Linear-guide print-head movement: the printing-head support uses linear guides for its travel.
• Vacuum worktable: the catalogue describes a porous metal table surface for distributing suction across the printing support.
• 350 mm web format: select artwork and label material within the specified width and print-area limits.

Configure the line around your label job

Provide the two-color artwork, label material, web width, print repeat, ink system and target output. Include registration marks and the alignment tolerance needed between colors so the application can be reviewed with actual material.

UV-curing conditions must suit both the ink and the substrate. Discuss heat sensitivity, the required cure and roll handling before confirming the line configuration. The catalogue lists a 220 V supply for the main machine and a separate 380 V supply for the UV dryers; confirm the complete electrical schedule and installation layout with the quotation.

For a single-color job, compare the WL-350D UV screen printing machine. You can also explore the roll-to-roll screen printing range.

When to shortlist the WL-350S

The catalogue lists two printing stations, two UV drying units, a 350 mm maximum web width and a 330 × 450 mm maximum print area. Use the number of required colors and their sequence to determine whether this configuration belongs on the shortlist. Compare the single-color WL-350D UV and the three-color WL-350-3C without assuming equal material width from their model names. The roll-to-roll guide explains the information needed for a comparison.

For a job-based choice between the three 350 mm configurations, see the WL-350D, WL-350S and WL-350DW comparison. It separates screen-color count from cold foil and lists the samples needed for a fair quote.
