SudoMock is purpose-built for programmatic long sleeve mockup generation at scale. Unlike browser-based tools that require manual uploads one at a time, SudoMock's REST API renders raglan long sleeve mockups at $0.002 per render with sub-second processing, making it ideal for POD sellers who need to generate hundreds or thousands of mockups automatically.
SudoMock's Multiply blend mode composites your design onto the white polyester surface while preserving the visible fabric texture underneath. The weave pattern, subtle sheen, and material characteristics show through your overlaid artwork, creating a photorealistic result that looks like the design was actually printed on the garment. This is especially effective for polyester fabrics where the smooth, slightly reflective texture adds realism.
SudoMock renders long sleeve mockup templates at up to 10,000 x 10,000 pixels, outputting in WebP, PNG, or JPEG format. This resolution exceeds what most POD platforms and marketplaces require, so your product listings will display crisp, professional imagery at any zoom level. The high resolution also makes these renders suitable for print catalogs and large-format marketing materials.
Yes. SudoMock's rendered mockups are standard image files (PNG, WebP, JPEG) that work with any POD platform including Printful, Printify, Gelato, Redbubble, and Gooten. You can also automate the full pipeline using SudoMock's native integrations with Shopify, WooCommerce, n8n, Zapier, and Make to push rendered mockups directly into your product listings.
This template includes six professional angles: front center view for the primary chest design area, a 3/4 angle showing garment dimension and side seam construction, a full back view for back print designs, a sleeve and cuff detail close-up highlighting raglan construction, a lifestyle shot in a modern office context, and a collar and neckline detail. All angles feature the shirt on a human model.
Use SudoMock's REST API to programmatically render designs onto this template. Send a POST request with your design image URL and the mockup template UUID, and SudoMock returns a rendered mockup in under a second. For no-code automation, connect SudoMock to your workflow via n8n, Zapier, or Make—so new designs are automatically rendered across all six angles and pushed to your store.
The white garment serves as the design placement surface in SudoMock's rendering pipeline. The pure white (#FFFFFF) polyester surface is where the rendering engine composites your artwork using Smart Objects. When combined with Multiply blend mode, the white base allows your design colors to appear accurately while the fabric texture shows through. This approach produces the most realistic results for any design color palette.
Industry standard front chest print placement for long sleeve t-shirts is typically 11.5 to 12 inches wide and 12 to 14 inches tall for a full-front design. For left-chest logo placements, 3.5 to 4 inches wide is standard. SudoMock's rendering engine handles design scaling and positioning within the Smart Object area, so your artwork is composited accurately regardless of the original file dimensions.
