Choosing a design

Understand your niche

Before you start designing, consider who you are making the shirt for. If it's for others, identify your target audience and niche market. Think about what would appeal to your target customers. You can also consider what you are knowledgeable and passionate about.

Do your research on T-shirt designs

Review the latest trends in the design world and see which ideas spark your creativity. You can use online resources and design tools to help with your research and execution.

Take advantage of online resources

If you're not a seasoned designer, there are plenty of online resources and professionals that can help bring your vision to life. You can hire a designer or work with multiple designers through design contests.

Brainstorm your design concept

Consider the type of T-shirt that would be appropriate for your target audience and goals. For example, a crop top might not be suitable for a law firm. Use an 18" x 18" canvas to sketch out your design ideas and ensure they translate well to the actual size.

Choose your colours wisely

The colours you choose will communicate a lot about your brand. Each shade and hue evokes an emotion, so select colours that align with the personality and message you want to convey. Also, consider using colour palettes and tools to help you choose the right shades.

Select your fonts carefully

The fonts you choose will also impact the overall impression of your design. Serif and script fonts are more classic, while sans-serif fonts are more modern. You can use fun, crazy display fonts, but make sure they don't compromise readability.

Evaluate your design

Evaluate your design by considering how it aligns with your goals and technical requirements. Get feedback from your team or people outside your organisation to gain fresh perspectives. Ask them questions like: "What is the one key message you get when you look at this shirt?" and "Who is this shirt for?".

Prepare the necessary files

Once your design is finalised, make sure you have the necessary files for printing. This typically includes your T-shirt design in vector format (AI, PDF, or EPS file) and colour codes (Pantone or CMYK colour codes) if custom colours are used.

Selecting a printer

Screen Printing

Screen printing is the gold standard for T-shirt printing. It is a reliable, affordable, and high-quality method that is ideal for large orders. However, a new screen is required for each colour or design revision, making colourful designs expensive. Screen printing is best for bulk orders and printing bright colours on dark shirts.

Heat Transfer Printing

Heat transfer printing can be done with paper or vinyl. This method is ideal for printing an entire image, letters, or abstract graphics. It requires little setup, has low costs, and uses basic tools. However, it is important to note that the paper and printing specifics differ for light and dark-coloured shirts. For light-coloured shirts, the transfer paper creates a mirror image, so the design must be flipped before printing. For dark-coloured shirts, the image is transferred exactly as it appears on the screen. Heat transfer printing is best for small orders and simple designs.

Direct-to-Garment (DTG) Printing

DTG printing is a newer option that uses inkjet printers to spray ink directly onto the garment. This method allows for highly customisable designs with intricate details and many colour choices. However, it is not suitable for dark-coloured garments and is best for small-quantity orders.

Preparing the T-shirt

The first step in preparing your T-shirt for printing is to select a high-quality image or design for your T-shirt. This can be anything from a logo to a photograph. If you are using a physical image, you will need to scan it or take a photo of it to upload it to your computer.

Next, you will need to purchase the correct type of transfer paper. Transfer paper usually comes in the same dimensions as printer paper, but if you want a different size, ensure your printer can handle it. There are two types of transfer paper: one for printing on light-coloured fabrics and one for darker fabrics. The former creates a mirror image, so you will need to reverse or mirror the image before printing.

Now you are ready to print your design onto the transfer paper. Before printing, check the preview to confirm that the image fits onto the paper. If it is too large, select "fit to scale" in the print options or scale it down in an image editing program. If your image is wider than it is tall, switch to "landscape mode".

Once your design is printed, cut it out. Any paper left around the image will show up as a thin film on the T-shirt. To get an accurate cut, use a ruler and a craft knife or a pair of extra-sharp scissors.

Now it's time to prepare your workspace. Choose a flat, hard surface that can withstand heat—a table, countertop, or cutting board will do. Cover the surface with a cotton pillowcase to protect it and the T-shirt.

The final step in preparing your T-shirt is to iron it. Place the T-shirt on top of the pillowcase and iron it until it is completely flat. Any wrinkles will show up in the transferred image.

Using transfer paper

Transfer paper is a great way to create custom t-shirts, garments, and fabric labels. It is also incredibly easy to use. There are two types of transfer paper: light transfer paper and dark transfer paper. Light transfer paper is used for light-coloured fabrics and creates a mirror image. Dark transfer paper is used for dark-coloured fabrics and does not require mirroring.

Step One: Prepare Your Workplace

Find a hard, firm, and heat-resistant surface to work on. Cover the surface with a cloth or any material to protect it from heat damage. Do not use an ironing board as it will not be able to withstand extreme pressure.

Step Two: Load Your Heat Transfer Paper

Load your heat transfer paper into a regular inkjet or laser printer, with the white side facing up. Ensure that your printer matches the specifications of your heat transfer paper. Set your printed output to "mirror pages" if printing on light-coloured fabrics.

Step Three: Choose and Prepare the T-Shirt

The transfer paper you use will depend on the colour of the fabric. White and light-coloured fabrics require light transfer paper, while dark-coloured fabrics require dark transfer paper. Iron the t-shirt to remove any creases or wrinkles before applying the transfer.

Step Four: Print Your Design

Print your chosen design onto the transfer paper, ensuring that the image is mirrored if printing on light-coloured fabrics. Test the mirror image by printing it on regular paper first. Crop the photo if you only want to transfer a portion of the image. Ensure that your image is sized correctly and will fit on the transfer paper.

Step Five: Cut Your Design

Cut out your design using scissors or a cutting machine. Cut as close to the design as possible to avoid leaving any blank spaces.

Step Six: Transfer the Design

Place the transfer paper onto the t-shirt, with the printed side facing down for light transfer paper and facing up for dark transfer paper. Cover the transfer paper with parchment paper to protect it from heat damage.

Step Seven: Apply Heat

Use a heat press machine or a home iron to apply heat to the transfer paper. If using a heat press machine, follow the manufacturer's instructions for temperature and pressing time. If using a home iron, set it to the highest temperature and apply firm pressure for 15-20 seconds in each position.

Step Eight: Remove the Transfer Paper

Allow the transfer to cool before removing the transfer paper. For light transfer paper, remove the backing paper while it is still hot. For dark transfer paper, remove the backing paper before ironing.

Washing Instructions

Turn the garment inside out and wash in warm or cold water with plain detergent. Do not use bleach or detergents containing whiteners or brighteners. Tumble dry on low or air dry. If ironing is required, do not iron directly on the transfer; cover it with baking parchment.

Ironing the design

Now that you've cut out your design, it's time to iron it onto the T-shirt. This is a crucial step in the process, as it will ensure that your design adheres properly to the fabric. Here's a step-by-step guide to ironing your design onto the T-shirt:

  • Place the T-shirt on a flat, hard surface. It's important to use a surface that can withstand heat, such as a table, countertop, or cutting board. Avoid using an ironing board, as the heat may cause it to bend or fold.
  • Cover the surface with a cotton pillowcase. This will protect the surface and the T-shirt from any potential damage.
  • Set your iron to the correct temperature. Check the instructions that came with your transfer paper, and select the recommended settings. If no specific instructions are given, set your iron to the "cotton" or high-temperature setting, and turn off the steam function.
  • Allow the iron to heat up for a few minutes. This will ensure that it reaches the desired temperature.
  • Place the T-shirt on the pillowcase and use the iron to remove any wrinkles. It's important to have a smooth surface before applying the design.
  • Place the transfer paper onto the T-shirt, with the design facing down for light-colored shirts and facing up for dark-colored shirts. Ensure that the design is centred and straight before proceeding.
  • Press the iron firmly onto the T-shirt, applying pressure with your whole hand. This will help transfer the design onto the fabric.
  • Move the iron as little as possible to maintain even, constant heat over the entire image. You want to provide heat to the entire surface of the image without moving the iron around too much.
  • Iron the design for the recommended amount of time. Check the instructions that came with your transfer paper, as the required time may vary. It can range from 30 seconds to several minutes.
  • Remove the iron and allow the T-shirt and design to cool down. This step is crucial, as it allows the design to set properly. Let it cool for at least a few minutes, until the paper reaches room temperature.
  • Carefully peel off the transfer paper to reveal your finished design!

By following these steps, you'll be able to successfully iron your design onto the T-shirt, creating a custom and unique piece. Remember to always read the instructions that come with your transfer paper, as they may have specific recommendations for the ironing process.
