How to Submit Your Artwork to Flags Unlimited

Ready to submit your custom flag artwork? Learn the two key submission methods (Email vs. FTP), file size limits, and a critical checklist to avoid common errors like using RGB or low resolution.

How to Submit Your Artwork

Once your artwork is properly prepared and meets all technical specifications, the final step is submitting your files to Flags Unlimited for production. We offer flexible submission methods to accommodate different file sizes and workflow preferences, ensuring your artwork reaches our production team quickly and securely.

Choosing the right submission method depends primarily on your file size. Small to medium files can be conveniently emailed, while larger files require our secure file transfer service. Regardless of which method you choose, always include complete information about your project to prevent processing delays.

File Submission Checklist

Before hitting send on your artwork submission, take a moment to review this comprehensive checklist. 

Ensuring all elements are included and properly prepared prevents delays, reduces back-and-forth communication, and moves your project smoothly into production. A complete submission package helps our production team deliver exactly what you envision.

  • All fonts outlined or converted to paths: Text elements will not reflow or change appearance
  • Linked images included in submission folder: No missing link errors will occur during production
  • Colours specified using Pantone Coated values: colour accuracy and reproduction will be predictable
  • File format matches requirements (.ai, .eps, .pdf, .psd, or .tif): Production equipment can process files without conversion
  • Resolution set to 100 PPI at 100% actual size: Print quality will be sharp without excessive file size
  • Special effects removed (shadows, transparencies, overprints): No unexpected visual anomalies will appear in final print
  • Sales rep email and job reference included: Files will be routed correctly and matched to your order

Common Artwork Mistakes to Avoid

Even experienced designers sometimes overlook critical details when preparing artwork for large-format flag and banner printing. 

Learning from common mistakes helps you avoid delays, additional costs, and disappointing results. Being aware of these frequent pitfalls ensures your artwork sails through production smoothly the first time.

Using RGB colour Mode Insufficient Resolution Forgetting to Outline Fonts Missing Linked Files

Designing in RGB instead of CMYK causes dramatic colour shifts when converted for printing. Colours that look vibrant on screen may appear dull or completely different when printed. Always work in CMYK from the start.

Scaling up low-resolution images results in pixelated, blurry prints. Design at actual size and 100 PPI from the beginning rather than trying to enlarge smaller artwork later.

Submitting files with live text causes font substitution problems if the production system doesn't have your exact fonts installed. Always convert text to outlines before submitting.

Failing to include images that are linked in your document creates broken image errors. Always package all assets together in a complete submission folder.

Avoiding these common errors demonstrates professional expertise and respect for the production process. When in doubt, consult the technical requirements or reach out to your sales representative for clarification. It's always better to ask questions before submission than to deal with production issues afterward.

By following these guidelines—using the correct templates, preparing files in the proper formats, managing colours accurately, maintaining appropriate resolution, and submitting complete packages—you'll ensure beautiful, vibrant results that exceed expectations.
