Customizing t-shirts is a creative and effective way to promote a brand, create merchandise, uniforms, or unique pieces for events. At Grafipronto , we use different techniques to guarantee the best result depending on the design, fabric, and desired quantity. In this guide, we explain the main printing techniques we use — DTF , digital transfer printing , and flex vinyl — and also present our premium and creative option: the Fullprint Unisex T-shirt , available exclusively online. 🎯 1. DTF (Direct-to-Film) Printing How it works: The design is printed onto a special film with pigmented inks, coated with polyurethane powder, and then transferred to the fabric using heat and pressure. ✅ Advantages: High color definition and very small details, ideal for intricate logos, photographic images with shadows, and white printing. It works on almost all types of fabric (cotton, polyester, blends, and dark fabrics). Good durability even after many washes. Allows for small print runs or one-of-a-kind pieces with excellent quality. ⚠️ Disadvantages: This process involves several steps, making production slower than simple stamping or vinyl printing. Slight embossing on the fabric, perceptible to the touch in highly saturated designs. 💡 Ideal for: Merchandising, custom uniforms, intricate designs with lots of detail, and colorful clothing items. 🎯 2. Digital Printing with Transfer How it works: The design is printed on special transfer paper using a Xerox digital laser printer with high-definition toner. Then, the transfer is applied to the t-shirt using a heat press , fixing the image onto the fabric. ✅ Advantages: Very fast production, ideal for short deadlines and small print runs. Vivid and crisp colors, excellent for simple images and logos. It allows you to print photos, gradients, and fine details. A good option for light-colored fabrics, especially white T-shirts . ⚠️ Disadvantages: On black or very dark t-shirts, the result may vary (sometimes it loses contrast or saturation). Less breathable in large areas due to the transfer film. Lower durability compared to DTF in very common washes. 💡 Ideal for: White T-shirts for events, giveaways, small print runs, and quick on-the-spot customization. 🎯 3. Printing on Flex Vinyl (Cut or Print) How it works: The vinyl is cut (for solid colors) or printed (for complex images) and then applied to the fabric with heat and pressure. ✅ Advantages: Very high durability, especially for logos and cut-out images. Possibility of special effects such as metallic, glitter, fluorescent or holographic . Good resistance to washing. ⚠️ Disadvantages: Less suitable for complex images with many details. Thicker and more "plastic" to the touch. More time-consuming for designs with many small elements. 💡 Ideal for: Names, numbers, simple logos, and pieces with special effects. 🆕 4. Unisex Fullprint T-Shirt The Fullprint Unisex T-shirt is the ideal choice for those seeking unlimited customization. With this technology, the print covers the entire surface of the t-shirt — front, back, sleeves and collar — creating a completely integrated and professional look. How it works: The custom design is printed in sections and directly onto the cotton or polyester fabric. After printing, the T-shirt is sewn on, resulting in a complete customization. The result is a vibrant, comfortable t-shirt with a completely soft feel. ✅ Advantages: Full print (front and back) with no visible margins or cutouts. Soft and natural to the touch, even in large prints. Vibrant colors, resistant to washing, and easy to iron. Production is possible in both 100% cotton and polyester , adapting to the desired purpose. Ideal for creative designs, advertising visuals, and exclusive collections. ⚠️ Disadvantages: Available only online , with a slightly longer production time as it is printed piece by piece and then assembled manually at the end. 💡 Ideal for: Custom brand creations, designer collections, creative events, and high-impact merchandising. 👉 View product in the online store 🏆 Quick Comparison Technique Speed ​​of Production Durability Touch Ideal For DTF Average High Smooth Complex designs and varied fabrics Digital Printing (Xerox + Transfer) High Average Average Quick customization and vibrant colors Vinyl Flex Reduced High Thick Simple logos and special effects Fullprint Average High Very smooth Complete prints and creative collections 👕 Grafipronto T-shirts At Grafipronto we have a variety of t-shirt colors for customization, although black and white models are the most common in stock for immediate production in local stores .

T-shirt characteristics: 190 g/m², 100% cotton jersey knit (shaded grey: 90% cotton / 10% viscose) Carded cotton yarn 1x1 ribbed collar Jersey reinforcement tape Double stitching on the sleeves and bottom. Tubular Regular cut Enzymatic treatment 🌱 Which one is more environmentally friendly? DTF: Water-based inks with reduced waste, but the film and dust are plastic. Digital Printing (Xerox + Transfer): Consumes little material and energy, but the transfer material is plastic that must be recycled. Vinyl Flex: Less sustainable, but very durable, using PVC. Fullprint: Solvent-free sublimation technology, with less environmental impact and no plastic waste. 📌 Conclusion Each technique has its place. If you're looking for speed , digital printing with transfer is unbeatable. If you need unique details and versatility , DTF is the right choice. If your focus is on visual impact and durability , flexible vinyl is ideal. And if you want total creative freedom , Fullprint is the premium solution — available exclusively online at Grafipronto . 📞 Contact us or visit our stores and discover which technique and T-shirt model is best suited for your project.

UV printing is revolutionizing the world of visual communication. With cutting-edge technology, high durability, and versatile materials, this technique produces impressive results—both in large format and on rigid surfaces. At Grafipronto , we rely on UV printing to ensure professional, durable, and personalized finishes without sacrificing sustainability. In this article, we explain what UV printing is, its advantages, and why it should be your choice for demanding projects. 🔍 What is UV printing? UV printing is a process in which ink is cured (i.e., dried) instantly by ultraviolet light immediately after being applied to the material. This immediate curing forms a solid, highly resistant, and adherent layer of ink that adheres to the printed surface—whether flexible or rigid. 📐 Large format UV printing UV technology is ideal for large-scale projects such as: Advertising canvases Self-adhesive vinyl Promotional posters Event exhibitors Decorative canvases and posters The colors remain vibrant even when exposed to sunlight, humidity, or frequent handling. It's the ideal solution for outdoor communication, stands, and points of sale. 🧱 UV printing on rigid materials One of the great advantages of UV printing is the possibility of printing directly onto rigid materials , such as: Acrylic PVC (Forex) KAPA® or foamboard Wood Glass Aluminum These stands offer endless possibilities for signage, interior decor, informational plaques, personalized gifts, and more—all with a high-definition finish. 🌱 Environmental advantages of UV printing UV printing is not only technically superior — it's also a more environmentally friendly option : No harmful solvents : UV ink does not release volatile organic compounds (VOCs), reducing pollution and protecting health. Less waste : instant drying prevents smudges and mistakes. Greater durability = fewer reprints . Compatible with ecological and recyclable materials . Equipment with UV LED technology consumes less energy. 🎨 Unlimited customization potential UV printing opens doors to creative, detailed and long-lasting personalization: Direct printing onto dozens of surfaces — rigid, flexible, light, dark or transparent. White backing paint allows you to highlight designs on clear acrylics or dark materials. Relief effects or tactile textures through overlapping layers. Ideal for small series or individual customization , with excellent cost-benefit. Whether for giveaways, promotional items, custom signage, or corporate decor, UV personalization is versatile and visually striking. 🔒 No laminating required — and it lasts longer One of the great advantages of UV printing is that it completely eliminates the need for lamination . The ink itself forms a layer that is resistant to wear, water, and UV rays. This means: Reduction of costs and production time Lower environmental impact (no plastic films) More natural final appearance , without shine or artificial thickness Fewer steps in the process = faster, more efficient production ✅ Why choose Grafipronto?
