LSA Contract Screen Printing Chosen For Dirk Nowitzki Foundation – Which Wich® Joint Promotion


Dallas screen printing company creates custom t-shirts for Dallas philanthropic joint venture.

Dallas, TX – LSA Contract Screen Printing, a 40-year veteran Dallas screen printer and restaurant apparel company, today announced their selection as supplier of custom designed t-shirts – “DirkShirts” – for The Dirk Nowitzki Foundation/Which Wich® Superior Sandwiches joint promotion.

The promotion was conceived to celebrate Nowitzki’s 20th year in the NBA, and, to thank him for the positive impact he has made on the Dallas area. For this campaign Which Wich created a new line of “DirkWiches”. A dollar for every DirkWich sold will be contributed to The Dirk Notwitzki Foundation which supports the wellbeing, health and education of children affected by poverty, illness, abuse, and neglect.

DirkShirts produced by LSA Contract Screen Printing, will be available for purchase at Which Wich locations in the Dallas area with proceeds benefitting the Foundation.

These custom t-shirts are also available for purchase online from the Which Wich website enabling Dirk and Mavericks fans outside Dallas to support the initiative. Click here for DirkShirts.

The DirkShirt begins with a luxurious American Apparel 100% fine jersey tee in black. It features an oversized imprint (19.5” x 22”) of Dirk Nowitzki in action on the elongated left chest. To maintain the soft “hand” and superior breathability of the fine jersey fabric, the image is screen printed with dye-extraction water-based inks. The back features the Dirk Nowitzki Foundation logotype at top center.

“We’re excited to be involved with this great campaign” said LSA founder Leonard Sloan. “Dirk is a great role model for Dallas, and, he’s had a positive impact on children in our community for years.”

LSA Contract Screen Printing was chosen as supplier of the The DirkShirt based upon its acknowledged superior color accuracy on black fabrics using dye extraction water- based screen printing.

When asked how he does it Leonard Sloan, founder of LSA, replied mysteriously “You can learn a lot about screen printing in forty years, if you pay attention.”
