Find answers to common questions about our garment printing services
We provide several printing techniques to suit different fabric types and design requirements. Screen printing works well for bulk orders with simple designs, offering durability and vibrant colours on cotton and cotton blends. Direct-to-garment (DTG) printing handles complex, multi-colour designs with photographic detail, ideal for smaller quantities.
Heat transfer vinyl is perfect for names, numbers, and bold graphics on sportswear. Sublimation printing creates permanent, full-colour designs on polyester fabrics. Each method has specific applications: screen printing requires minimum quantities of 25 pieces, while DTG accepts single-item orders. We'll recommend the most suitable technique based on your fabric choice, design complexity, and order volume.
Standard production time is 5-7 working days after artwork approval. This includes printing, quality checks, and packaging. Orders under 50 items typically complete within 5 days, while larger quantities may require the full 7 days.
Express service is available for urgent orders, reducing turnaround to 2-3 working days with a 30% surcharge. Delivery within London takes 1-2 days via courier, while UK-wide shipping adds 2-3 days. We send digital proofs within 24 hours of receiving your design files. Once you approve the proof, production begins immediately. Complex designs requiring colour matching or special preparations may add 1-2 days to the timeline.
Vector files produce the best results: AI, EPS, PDF, and SVG formats at any size without quality loss. For raster images, we accept PNG, JPEG, and TIFF files with minimum resolution of 300 DPI at the intended print size. A design measuring 30cm wide should be at least 3500 pixels wide.
Avoid low-resolution images from websites or social media, as these appear pixelated when printed. If you only have a low-quality file, our design team can recreate it as a vector for £25-50 depending on complexity. We also accept hand-drawn sketches or photographs of existing designs, which we'll convert to print-ready files. All text should be converted to outlines or curves, and colours specified in Pantone or CMYK values for accurate reproduction.
Yes, we accept customer-supplied garments with certain conditions. Items must be new, unwashed, and free from creases or packaging marks. We require 10% extra pieces beyond your order quantity to account for potential printing errors or fabric defects. All garments should arrive clean and ready for printing.
Our printing service charge applies regardless of garment source: £4.50 per item for single-colour prints, £6.50 for multi-colour designs. We cannot guarantee results on unknown fabric blends or pre-treated materials. Synthetic fabrics require specific inks, so inform us of fabric composition in advance. We inspect all supplied items before printing and will notify you of any unsuitable pieces. Damaged or soiled garments will be returned unprinted.
Proper care extends print life significantly. Turn garments inside out before washing to protect the printed surface. Use cold or warm water (maximum 30°C) with mild detergent, avoiding bleach or harsh chemicals. Machine wash on gentle cycle or hand wash for best results.
Air drying is preferable, but if using a tumble dryer, select low heat. Never iron directly on printed areas; place a cloth between the iron and print, using low to medium heat. Avoid dry cleaning unless specifically stated as safe for your print type. Screen-printed items withstand 50+ washes when cared for properly. DTG prints maintain quality for 30-40 washes. Heat transfer designs last 25-30 washes with correct care. Store printed clothing in cool, dry places away from direct sunlight to prevent fading.
Minimum quantities vary by printing method. DTG printing accepts orders from 1 piece upward, making it suitable for personal projects or testing designs. Screen printing requires minimum 25 pieces per design and colour combination due to setup costs involved in creating screens.
Heat transfer vinyl has no minimum, accepting single items. Embroidery services start at 10 pieces. Larger orders receive volume discounts: 50-99 pieces get 10% off, 100-249 pieces receive 15% discount, and 250+ pieces qualify for 20% reduction. Mixed sizes within the same design count toward quantity discounts. For corporate orders exceeding 500 pieces, we offer custom pricing. Sample pieces are available before committing to large orders, charged at single-item rates.
Our in-house design team creates custom artwork from your ideas. Basic design services include text layout, font selection, and simple graphics for £35. This covers straightforward logos or text-based designs with up to two revision rounds.
Complex designs with illustrations, multiple elements, or detailed graphics start at £75, including three revision rounds. We provide initial concepts within 2-3 working days. Rush design service delivers concepts in 24 hours for an additional £25. Bring reference images, colour preferences, and any existing branding materials to your consultation. We'll discuss your vision and create mockups showing how the design appears on actual garments. All design files become your property after final payment, supplied in multiple formats for future use.
We guarantee satisfaction with our printing quality. If prints have defects due to our error (misprints, incorrect colours, or poor adhesion), we'll reprint the affected items at no charge. Report issues within 7 days of delivery with photographs showing the problem.
Our quality control checks every item before dispatch, but occasionally issues arise. We don't reprint items if the problem stems from approved artwork errors, incorrect information you provided, or damage from improper care after delivery. Colour variations between screen displays and printed results are normal; we provide physical colour samples upon request before production. For large orders, we recommend ordering a sample first. Minor variations in print placement (within 2cm) are standard in garment printing. Refunds are available if we cannot resolve quality issues to your satisfaction within 14 days.
We specialise in custom garment decoration, bringing your designs to life with precision and care. Since our establishment, we've been serving businesses and individuals across London with reliable textile printing solutions.
Zowosi began operations in 2015 when a group of textile industry specialists identified a gap in the London market for accessible, dependable garment decoration services. Starting from a modest workshop in Clerkenwell, we focused on understanding client requirements and delivering consistent results.
What started as a small operation with two printing machines has grown into a facility equipped with multiple printing technologies. We've expanded our capabilities to include screen printing, direct-to-garment digital printing, and heat transfer applications. This growth came from listening to customer needs and investing in equipment that allows us to handle diverse projects.
Today, we operate from our location on Amwell Street, serving over 300 regular clients ranging from independent designers to established retail brands. Our team consists of 12 trained technicians who handle everything from artwork preparation to final quality checks.
We aim to provide straightforward garment decoration services that meet deadlines and specifications. Our focus is on maintaining consistent output quality while keeping pricing transparent and communication clear throughout each project.
We're working to become the go-to textile printing partner for London-based businesses by continuing to invest in modern equipment, training our staff in new techniques, and maintaining the service standards that our current clients rely on.
We track our on-time delivery rate, which currently stands at 96%. When we commit to a deadline, we structure our production schedule to meet it.
Our quotes break down costs clearly. We explain what each printing method involves, its limitations, and expected durability so you can make informed decisions.
Every order goes through a three-stage inspection process: pre-production artwork check, mid-production sample review, and final batch inspection before dispatch.
You'll have direct contact with a project coordinator who handles your orders. They're available during business hours to answer questions and provide updates.
Over eight years, we've processed approximately 45,000 orders. This volume has taught us how to handle various fabric types, from standard cotton to technical sportswear materials. We've learned which inks work best for different applications and how to troubleshoot common printing challenges.
Our equipment includes four automatic screen printing presses, three DTG printers, and heat press stations. We maintain backup machines to prevent delays if equipment needs servicing. Our facility can handle orders from 10 pieces to 5,000 units, with typical turnaround times of 5-7 working days for standard orders.
We work with established suppliers for blank garments and use water-based and plastisol inks that meet UK safety standards. For clients requiring specific certifications, we can provide documentation for Oeko-Tex certified materials and eco-friendly ink options.
