Designing T-Shirts With Krita: A Step-By-Step Guide

Krita is a free and open-source raster graphics editor designed for digital painting and animation. It is a popular tool for designing T-shirts, with several users on forums sharing their experiences and advice on how to create high-quality T-shirt designs using the software. Krita offers a wide range of customisable tools, such as brush control, colour and blending modes, opacity, and effects settings. It also supports tutorials and has an intuitive interface, making it accessible to users of all skill levels.

Using a graphic tablet to draw

When using a graphic tablet, you can start by creating pencil sketches and then scanning them into Krita. This provides a base for you to work on and allows you to focus on the details of your design. The next step is to use the inking feature in Krita to go over the pencil lines, adding precision and clarity to your drawing. Krita offers a wide range of brush presets, which are easily accessible and can be used to enhance your artwork.

Brush presets are a key strength of Krita, and they can be extremely useful for adding shades and lights to your design. Artists like David Revoy have created custom brush sets that are available for free, providing you with a variety of options to experiment with. You can also adjust the thickness of existing ink lines and play around with lighting and colour effects to achieve the desired look for your T-shirt design.

Additionally, Krita offers a G'MIC colourise filter, which simplifies the colouring process. This filter allows you to indicate with coloured dots which regions of your design should be filled with specific colours. The filter then suggests a colourisation, finding sensible borders between regions. This can save you a lot of time and effort in the design process.

By utilising the features of Krita and the precision of a graphic tablet, you can create high-quality T-shirt designs that are ready for printing.

DPI and resolution settings

When designing a T-shirt in Krita, it is important to set the correct DPI and resolution settings to ensure your design prints clearly and without pixelation. DPI, or dots per inch, refers to the resolution of the printed image, and is a key factor in determining the quality of your print. A higher DPI means a higher-quality print, as it allows for more detail and smoother edges.

For T-shirt printing, a resolution of 300 DPI is standard and will produce a good-quality print. However, you may want to check with your printer to be sure, as some printers may require a higher resolution, especially if you are printing photorealistic images or using certain types of fabric. If you are unsure, it is always better to create your design at a higher resolution, as you can always downscale if needed.

When setting up your document in Krita, you will need to specify the DPI and the dimensions of your print in inches, centimetres, or millimetres. For example, if you want your design to be 18 inches across the chest, you would set your document size to 18 inches wide, and then set the DPI to 300. This will give you a high-quality print that will not appear pixelated.

It is important to note that the resolution of your design is not the same as the resolution of your screen. Your screen resolution may be much higher than the resolution of your print, so be sure to set the correct DPI and document size in Krita to ensure your design prints at the correct size and quality.

In addition to DPI and resolution, there are a few other factors that can affect the quality of your T-shirt print. The type of fabric you are printing on can make a difference, as some fabrics may absorb and spread the ink more than others. The number of colours in your design can also impact the cost of printing, as using more colours can be more expensive. Finally, the method of printing you choose, such as screen printing or direct-to-garment, will also affect the final outcome of your design.

Vector art design

If you're looking to design a T-shirt using Krita, a free and open-source digital painting application, you may want to consider creating a vector art design. Vector art designs are ideal for printing as they can be scaled up or down without any loss in quality, ensuring your design is smooth and not pixelated or blurry.

To create a vector art design in Krita, you'll need to use the program's Vector Layer feature. This allows you to create vector graphics, which are based on mathematical formulas rather than individual pixels, making them highly flexible for resizing. Here are some steps you can follow to create your vector art design:

• Familiarize yourself with the Vector Tools: Krita offers a range of vector tools, including shape tools, path tools, and transformation tools. Experiment with these tools to understand their capabilities and limitations.
• Set Up Your Document: Before you begin designing, set up your document according to the requirements of your printer or printing service. The recommended resolution for T-shirt printing is often around 300 DPI, but it's always best to check with your chosen printer.
• Create Your Design: Start by sketching out your ideas using the vector tools. You can create shapes, lines, and paths to form the basis of your design. Remember that vector graphics are best suited for crisp, clean designs, so keep your artwork simple and avoid intricate details that may be lost during printing.
• Add Colour and Effects: Fill your shapes with colours, gradients, or patterns to bring your design to life. You can also explore the various vector effects available in Krita, such as shadows, transparencies, and blends, to add depth and visual interest to your artwork.
• Refine and Edit: As you work, you can easily edit your vector artwork by adjusting nodes and paths. This allows for precise modifications to your design without affecting the overall quality. Take advantage of this flexibility to perfect your T-shirt design.
• Save and Export: Once you're happy with your design, save your work in a compatible vector format, such as SVG or EPS. This will ensure your artwork remains scalable and can be easily printed or edited in the future.

Remember that vector art is particularly useful for designs that need to be reproduced at various sizes, so if you're planning to print your design across different T-shirt sizes or on other merchandise, vector art is an excellent choice.

Brush presets

Krita comes with a large collection of brush presets, designed to help both beginner and advanced users. These presets can be used for various purposes, including comic inking and colouring, digital painting, mate painting, pixel art, and 3D texturing.

The basic brush family, for instance, uses a basic circle for the brush tip with variations in opacity, flow, or size. These brushes are named 'Basic' because they are the fundamental tools of every digital painting program and work quickly due to their simple properties.

Krita also offers a range of inking brushes that can be used to produce line art and high-contrast illustrations. These include:

• Ink Precision: A thin line designed for taking notes or drawing tiny details.
• Ink Fineliner: A preset with a regular width used for tracing panels, technical details, or buildings.
• Ink GPen: A preset with a dynamic size for smooth inking.
• Ink Pen Rough: A preset that focuses on creating a realistic ink line with irregularities, such as the texture and fibre absorption of paper.
• Ink Brush Rough: A brush that captures the delicate paper texture at low pressure, as if the brush slightly touches the paper.
• Ink Sumi-e: A brush that reveals the thin texture of each bristle, making the line highly expressive.

Additionally, Krita provides a range of marker presets, dry painting brushes, and chalk, pastel, and charcoal brushes, each offering unique textures and effects.

Users can also create and save their own custom brush presets in Krita. This involves adjusting the various settings within the Brush Settings Editor panel, including the brush engine, size, opacity, flow, and spacing. Once the desired settings are achieved, users can save their customised brush as a new preset.

Custom patterns
