At PensXpress.com, we aim to make the customization process as smooth as possible. To ensure the highest quality imprint of your logo, we recommend sending vector files (.AI, .EPS, or .PDF formats) with all fonts outlined. These types of files provide the best quality and allow for more flexibility in resizing your logo without loss of quality. If vector files are not available, high-resolution bitmap images (.JPG, .PNG, .TIF) may also be used, but they should be at least 300 DPI to ensure good print quality. To upload your logo, simply follow the instructions on the product customization page or attach the file in an email if directed by customer service. If you have specific color preferences, be sure to include those details, preferably in the Pantone color system for best matching. Please consult our customer service team if you have any questions or encounter any issues when uploading your logo. We're here to help you every step of the way to ensure your custom pens meet your expectations.
