Strike-Off Vs Lab Dip: Which Color-Approval Sample Do You Need?

Strike-Off A sample print produced to evaluate artwork, color, scale, and print quality before bulk fabric production.

Both strike-offs and lab dips are pre-production color-control tools, but they serve different purposes. A lab dip is a swatch dyed to match a target color on a specific fiber and dye system; a strike-off reproduces the actual printed design on the production fabric. Choosing between them depends on whether the risk you need to mitigate centers on dye formulation and fiber response (lab dip) or on how inks, artwork, and printing processes behave on the substrate (strike-off).

Primary Differences

• Scope: Lab dip: single solid color on fabric; Strike-off: full design including separations, halftones, and multi-color interactions.
• Goal: Lab dip: validate dyestuff/fiber match; Strike-off: validate printed outcome of artwork and process.
• Typical Use: Lab dip: textile dyeing for solids or ground colors; Strike-off: screen, rotary, or digital printing of patterns and graphics.
• Measurement: Lab dip: primarily spectrophotometric color match; Strike-off: both instrument and visual checks for color plus registration, detail, and hand.

When A Lab Dip Is The Right Choice

Request a lab dip when your production is dyed rather than printed; for example, when ordering a bulk batch of a single-color fabric, rib, or trim. Lab dips isolate the dye-fiber interaction and are usually less expensive and faster than strike-offs. They are the standard step when color must match across different substrates (knit vs. woven) because they show how a particular dye recipe reads on each material.

When A Strike-Off Is The Right Choice

Request a strike-off when the visual result depends on artwork, separations, printing process, or special effects (metallics, discharge, foil). If your product has multi-color repeats, fine-line detail, or relies on halftones and gradients, a strike-off shows how these elements interact with the fabric and finish. Strike-offs are essential for garments where pattern placement or seam matching matters.

Practical Decision Matrix

• If The Order Is Solid-Dyed: Start with a lab dip; progress to a strike-off only if the fabric will be printed or treated later.
• If The Order Is Patterned/Printed: Require a strike-off that uses the actual artwork, substrate, and production inks.
• If Multiple Substrates Are Used: Request a lab dip for each substrate for dye matching and a strike-off for the patterned substrate.

Combining Both Approaches

In many production chains both samples are used. A lab dip defines the base color targets and dye recipe, while a strike-off confirms how separations, ink formulations, and post-processing alter the appearance. Use lab dip data to set spectral targets and then confirm them on the strike-off so both dye house and printer work from the same objective standards.

Cost And Lead-Time Considerations

Lab dips are usually quicker and cheaper because they require less setup and no screen or print engineering. Strike-offs cost more due to artwork preparation, screen making or printer configuration, and the need to match production processes. Budget strike-off lead times into your development calendar—rush fees apply if you need them faster than standard supplier turnarounds.

In short, the Strike-Off is the targeted, process-specific sample that verifies final printed appearance and print quality. Use lab dips to validate base color on fiber; use strike-offs to validate how your design, inks, and production process translate that color and artwork onto the actual fabric.
