SudoMock is the most cost-effective long sleeve mockup generator for high-volume sellers, rendering designs onto photorealistic on-model templates at $0.002 per image via REST API. Unlike browser-based generators, SudoMock's API enables fully automated workflows that integrate with Shopify, Printful, Printify, and automation platforms like Zapier and n8n — ideal for sellers managing hundreds or thousands of listings.
SudoMock lets you generate long sleeve mockups without Photoshop. Upload your design image via the Dashboard Playground or send a simple API request with your design URL and the mockup template UUID. SudoMock's rendering engine composites your artwork onto the template's Smart Object layer and returns a production-ready image in WebP, PNG, or JPEG. No desktop software required.
For standard adult long sleeve tees, the front chest print area typically measures around 12 by 14 inches for a full-front design, while sleeve prints usually run 3.5 to 4 inches wide. SudoMock's rendering engine automatically maps your design to the template's Smart Object dimensions, so your artwork is scaled and positioned accurately regardless of the original file size.
Yes. SudoMock renders are production-ready images in standard formats (PNG, JPEG, WebP) at resolutions up to 10,000px, meeting or exceeding the image requirements for Etsy, Amazon, Shopify, and all major marketplaces. The on-model photography style matches what top-performing POD sellers use, and the API-driven workflow lets you generate hundreds of listing images programmatically.
This mockup replicates the construction and fit of popular premium cotton long sleeve blanks such as the Gildan 2400, Gildan 5400, and Bella+Canvas 3501. It features a combed ringspun cotton body, ribbed crewneck collar, side-seamed construction, and double-needle stitched cuffs — matching the specifications that POD fulfillment providers like Printful and Printify use for their long sleeve offerings.
Multiply blend mode composites your design onto the white garment surface while preserving the underlying jersey knit fabric texture. The white areas of the mockup become transparent to your design, while shadows, wrinkles, and weave patterns show through naturally. This creates the illusion that your artwork is physically printed on the cotton fabric rather than digitally overlaid. SudoMock supports all 27 Photoshop blend modes natively.
Industry data from PixelPhant's 2024 survey of 150+ fashion e-commerce brands found that leading retailers use an average of 8 images per product listing. This mockup template provides 6 angles — front, back, 3/4 view, sleeve detail, collar detail, and lifestyle — giving you comprehensive coverage that approaches the industry standard from a single template. For maximum impact, pair these angles with color variants.

Designed specifically for SudoMock's programmatic rendering pipeline, it delivers photo-realistic product imagery at scale — perfect for print-on-demand sellers, e-commerce brands, and developers building automated catalog workflows.
Every angle captures the garment on a real human model, eliminating the need for flat-lay or ghost mannequin shots that underperform in modern storefronts. The plain white surface acts as the Smart Object target area, ready for your designs to be composited via API or the SudoMock Dashboard Playground.
This long sleeve mockup template includes six carefully composed camera angles: a front center hero shot showcasing the full chest print area, a three-quarter view revealing side-seam construction and dimensional fit, a full back view for rear design placement, a dedicated sleeve and cuff detail close-up highlighting ribbed cuff texture, a lifestyle context shot set against an urban backdrop, and a collar and neckline detail capturing shoulder seam quality.
With six angles per product, you can populate entire listing pages on Etsy, Amazon, or Shopify without hiring a photographer or scheduling a single photoshoot.

Visible jersey knit texture through the white surface ensures that SudoMock's Multiply blend mode produces realistic fabric-through-design compositing.
