Apparel Designer Needed to Optimize Existing T-Shirt Artwork for Premium Print Quality

I am looking for an experienced apparel graphic designer to help refine my existing T-shirt designs and prepare them for high-quality garment printing through Printful. The goal is to ensure the final printed shirts have rich, vibrant colors and a premium look that matches the original design vision. I need someone who understands the difference between artwork that looks good digitally and artwork that translates beautifully onto fabric. The ideal candidate will have: * Experience designing for apparel printing * Knowledge of DTF, DTG, and/or screen printing processes * Experience preparing print-ready artwork files * Familiarity with Printful’s design guidelines, file requirements, product templates, and print recommendations * Strong attention to color accuracy, detail, and production quality Scope of Work: * Review existing T-shirt artwork and identify opportunities to improve print quality * Optimize colors, saturation, contrast, and overall visual impact for garment printing * Ensure artwork is properly prepared for Printful production requirements * Recommend adjustments based on the specific shirt blanks and printing method being used * Provide guidance on achieving the richest, most premium final printed result Deliverables: * Color-optimized artwork files for apparel printing * High-resolution print-ready files (300 DPI) * Transparent PNG files * Vector files (AI/SVG/EPS preferred) * One realistic shirt mockup * Recommendations for Printful settings, file preparation, and/or printing method Please include: * Examples of apparel designs you have prepared for production * Your experience with Printful or similar print-on-demand platforms * Your experience with DTF, DTG, or screen printing * A brief explanation of how you would approach improving a design that printed too dull or muted Please only apply if you have experience preparing artwork for actual garment production. This is not a logo design project — the focus is print quality, color optimization, and apparel execution.
