Choose a nonwoven
bag printing machine.

Choosing a nonwoven bag printing machine is a production decision as well as a colour decision. Share the artwork at the intended size, the number of colours on each side, the fabric type and weight, any coating or lamination, and the required appearance.

Then check the print width, repeat length, roll dimensions, drying conditions and downstream bag layout. A sample with acceptable colour and adhesion on one fabric does not establish the same result on a different surface.

Printing is separate from bag making. The printed material must be prepared in the format required by the selected bag machine: a compatible roll for a roll-fed line, or correctly prepared pre-cut sheets for a sheet-fed line.

These are different process and machine specifications. A printing speed in metres per minute and a bag-making speed in bags per minute are not directly comparable.

The YT41200 uses four printing stations, metal anilox rollers, rubber rollers and electric hot-air drying. Longitudinal and lateral colour registration are adjusted manually. Its maximum printing speed is 60 m/min; the workable speed depends on the material, artwork, ink and drying conditions.

The specified repeat range is 250–1,000 mm. The standard supply includes four plate cylinders, one per colour, with a supplied repeat length up to 300 mm. A repeat above 300 mm requires the appropriate cylinder set, so include the artwork repeat when asking for a configuration and price.

For a four-colour design, provide separated artwork and the expected print position relative to the bag folds, seams and handles. Confirm whether the design fits a single-sided 4 + 0 production plan.

The FB-NWF 12010WII is a two-colour roll-to-roll screen printing line with servo control, automatic ink feeding, drying and rewinding. It is a route to evaluate when a design calls for a substantial ink layer on nonwoven fabric.

Its published nonwoven material range is 40–100 g/m² and its maximum print area is 1,200 × 1,100 mm. Confirm the actual artwork, fabric and screen setup together. Ask to assess appearance, coverage, adhesion and drying on a material sample before deciding the production specification.

Colour count alone does not determine which process to choose. The required print result, order size, repeat, setup work and material behaviour all contribute to the decision.

To compare stages, convert the printing rate to an approximate bag equivalent using the actual web layout: printed metres per minute ÷ metres of web used per repeat × bags represented by that repeat. Check that the layout, lanes and cutting arrangement are valid for the selected bag-making process.

Allow for drying, roll changes, artwork changes, waste and the buffer of printed material between stages. The slowest available stage can limit the overall production plan even when the bag-making machine has a higher rated speed.
