Brand Story

Ghana's Star Oil (official website: www.staroil.com.gh) is a well-known local energy enterprise. This time, it customized 12 styles of full-print T-shirts for brand activities and employee image display. As an energy sector brand, it has strict standards for the design accuracy, craftsmanship quality, and delivery efficiency of customized clothing, requiring professional OEM services to realize multi-style production in a short cycle.

Brand Goals

Star Oil aimed to enhance brand visual recognition through 12 customized T-shirts for event promotion and employee wear. Due to the fixed event time, it required 12 styles of samples to be made within 5 days, with design consistency with renderings and precise dimensions to lay the foundation for subsequent mass production.

Challenges

Craftsmanship and style pressure: Full-print craftsmanship is complex; 12 styles have distinct designs; there are differences between the client’s renderings and actual cutting pieces, requiring quick adjustments.

Tight delivery cycle: The entire process of design, sampling, and production needed to be completed within 5 days, much shorter than the conventional sample cycle.

Strict quality requirements: Dimensions must strictly meet standards (only positive tolerances allowed); sewing must be completely consistent with renderings without deformation or misalignment.

Complex process connection: Samples need to be sent to the exhibition hall for inspection and photography first, then re-sent to the client, requiring high timeliness and packaging integrity for delivery.

Strict qualification review: Complete production qualification documents need to be provided to ensure compliance of cooperation.

Solutions

Rapid design response: A special design team was established to adjust differences between 12 sets of renderings and cutting pieces within 1 day, confirm the final production plan, and synchronize sampling.

Integration of production resources: Allocated priority production in the full-auto printing center and sewing center; adopted a seamless connection mode of "design-sampling-production" to shorten transfer time.

Full-process quality control: Arranged special personnel to check dimensions and sewing details; each style of sample passed 3 quality inspections to ensure consistency with renderings. Communicated delivery processes in advance and used reinforced packaging to ensure transportation safety.

Efficient qualification docking: Collated and submitted complete qualification documents within 4 hours, passing the client’s review.
