Large Format Screen Printing Projects We've Run and What Made the Scale Work

Large format screen printing — also called jumbo screen printing or oversized screen printing — refers to garment decoration that extends significantly beyond the area of a standard chest or back print. Where a typical back print runs 12 to 14 inches wide, large format printing can cover 16 to 18 inches or more, reaching toward the side seams and hem to produce a graphic that fills the entire garment.

Garment Decor offers large format screen printing in-house at our Montclair, CA facility on M&R Challenger 3 automatic presses with dedicated jumbo printing capability. Maximum print area: 17" × 23". Minimum order: 50 pieces. Available in spot color, simulated process, puff, and combination techniques.

What Makes Large Format Screen Printing Different to Execute

The mechanics of large format printing aren't complicated to describe — but they're harder to run cleanly than most buyers realize.

• Larger screens, longer stroke. Jumbo printing requires bigger screens than standard setups and an extended press stroke to cover the full print area. Shops that run jumbo work occasionally tend to produce results that show registration drift at the outer edges of the design, where the screen's tension is lowest.
• Registration precision compounds with scale. On a 12-inch standard back print, a half-millimeter registration error is barely visible. On a 17-inch jumbo print, the same error shows clearly at the edge of the design where two colors meet. Maintaining tight registration across a full jumbo run requires calibrated tension, consistent squeegee pressure, and automatic presses that don't drift between pulls.
• Simulated process is the technique that makes complex jumbo work possible. Most large format designs have more color depth than a simple spot-color palette can reproduce. Simulated process printing uses halftone dot patterns to replicate gradients, shading, and photorealistic color from a limited ink set — and at jumbo scale, the halftone detail reads more cleanly because each dot has more surface area to resolve against.
• Blank selection is part of the output. A heavyweight, dense cotton surface — garment-dyed or otherwise — holds ink at large coverage areas without the bleed that can happen on lightweight fabrics. A thin blank under a jumbo print produces inconsistent ink saturation that shows at scale in a way it wouldn't on a standard placement.

Five Large Format Projects from Our Shop

H.E.R. Concert Hoodies — 250 Units in 3 Days

• Blank: LA Apparel HF09GD Heavy Fleece Hoodie (14 oz, garment-dyed, 100% US cotton), unisex oversized fit
• Design: H.E.R. jumbo back print, 4-color simulated process (white base, highlight white, light gray, black)
• Quantity: 250 units
• Turnaround: 3 business days
• Finishing: Custom screen-printed neck tags, retail finishing, couriered directly to venue

Concert merch for H.E.R. — 250 LA Apparel HF09GD hoodies with a jumbo simulated process back print, produced and delivered to venue in 3 business days. The HF09GD's 14 oz garment-dyed fleece is one of the most demanding print substrates we run: the heavyweight pile requires adjusted ink deposit to achieve even saturation, and the oversized silhouette means the jumbo design has proportionally more fabric to fill. The 4-color simulated process build — including a base white and highlight white for working on the dark fleece — produced gradient detail that reads at stage and fan distance. Retail-finished and couriered to the venue so the team could focus on the show.

Frank Ocean Tour Merch — 800 Units in 3 Days

• Blank: LA Apparel 1801GD (6.5 oz, garment-dyed, 100% US cotton), black
• Design: SHUTUPPLS FRANK OCEAN 1.14 — 8-color simulated process, front and back
• Quantity: 800 units
• Turnaround: 3 business days
• Finishing: Custom screen-printed neck tags, retail finishing, couriered directly to venue

800 LA Apparel 1801GD tees with an 8-color simulated process jumbo design on front and back, produced and couriered to Frank Ocean's venue in 3 business days. Running 8-color simulated process on both sides of a heavyweight black tee at this volume and timeline requires M&R automatic press throughput, experienced color separation, and a production team that's run the technique enough times to know exactly where each ink channel has to land to avoid muddying the gradient work. High mesh screens were used to capture fine detail in the artwork. The 1801GD's garment-dyed cotton surface held the ink cleanly across the full coverage area of both placements.

Kendrick Lamar Tee by RG — 1,500 Units in 7 Days

• Blank: LA Apparel 1801GD, black
• Design: KENDRICK LAMAR TEE BY RG — 8-color simulated process jumbo back print
• Quantity: 1,500 units
• Turnaround: 7 business days
• Finishing: Custom screen-printed neck tags, poly-bagged with size stickers

1,500 LA Apparel 1801GD tees with an 8-color jumbo simulated process back print, delivered retail-ready in 7 business days. At 1,500 units, the production challenge shifts from single-run quality to sustained consistency across a full day of press time — every print in the run needs to match the approved sample in ink density, registration, and color accuracy. Poly-bagged with size stickers, each tee arrived retail-ready with no additional prep required by the client's team.

Lost Intricacy — Jumbo Print on Custom Distressed Tees

• Blank: Custom distressed tee (6.5 oz, 100% US cotton, garment-dyed, drop shoulder, oversized)
• Design: Skeleton Bat by Lost Intricacy — oversized jumbo front print
• Decoration: Jumbo screen printing

A jumbo screen printed project for Lost Intricacy on custom distressed tees — a 6.5 oz garment-dyed drop shoulder blank with a pre-distressed finish. Distressed fabrics present a specific production challenge for jumbo printing: the surface irregularities from the distressing process create variation in how ink adheres across the print area. Managing that variation across a full-coverage jumbo design while maintaining a clean, intentional result is the kind of problem that separates shops that understand large format printing from those that don't.

Dreams Clothing Co — 750 Units in 5 Days

• Blank: LA Apparel 1801GD, black
• Design: DREAM$ ® Astro-Boyz Tee — 8-color simulated process, front and back
• Quantity: 750 units
• Turnaround: 5 business days
• Finishing: Custom screen-printed neck tags, retail finishing (fold, bag, size tags)

750 LA Apparel 1801GD tees with 8-color simulated process jumbo printing on both front and back, delivered retail-ready in 5 business days for Dreams Clothing Co. The DREAM$ Astro-Boyz design required the full back and front to carry distinct, detailed artwork simultaneously — each side its own production setup, each side requiring sample approval before the run began. Retail finishing, including custom neck tags and fold-and-bag packaging, was included in the same production window. The client's deadline was met without extension.
