If you're looking to use variable fonts in print design, there are certain tips and steps to keep in mind. Start by selecting a variable font that fits your project and audience, and has the axes and features you require. You can find such fonts on websites like Google Fonts, Adobe Fonts, or Axis-Praxis. Then, use a software or device that supports variable fonts, such as Adobe Illustrator, InDesign, or Photoshop. You can also explore and test various fonts with online tools such as Font Playground or Wakamai Fondue. Adjust the font variations according to your design goals using sliders, inputs, or code. Additionally, consider presets or instances, which are predefined points along the axes that correspond to common font styles. To ensure accuracy, preview the font variations with simulations or tests. Compare them with other fonts or styles to assess readability and legibility too. Finally, export or print your design in a format that preserves the font variations such as PDF or SVG. You can also embed or package the variable font file with your design for viewing on different devices or platforms.
