How should I prepare print-ready design files?

1. 1Prepare the logo as a vector fileVector files such as AI, PDF and EPS keep clean edges when enlarged. Methods that make plates or paths, such as screen printing, laser engraving and foil stamping, need vector files.
2. 2Convert text to outlinesConvert text to outlines before sending so the lettering does not change where the font is not installed. The copy may need edits, so keep the file from before conversion as well.
3. 3Prepare images at 300 dpi or more at actual sizeWhen using photos or raster images, check that the images are 300 dpi or more at the actual printed size. Low-resolution images downloaded from the web print blurry.
4. 4Specify colors as CMYK or Pantone numbersRGB colors on a monitor cannot be reproduced exactly with printing ink. Use CMYK for full-color printing and give Pantone numbers for brand colors that must match exactly to reduce color differences.
5. 5Thicken fine lines and small textVery fine lines may not print, so keep line weights generous. Embroidery needs taller lettering because of the thread thickness.
6. 6Plan a white base for dark backgrounds and clear materialsWhen printing on dark fabric or clear materials, white often needs to be printed first so colors do not sink into the background. Marking the white print area separately in the design file makes the work more accurate.
7. 7Confirm with a physical mockupThe same file can give different results depending on the material and method. Before a large run, checking color and position with a mockup or sample is the safe choice.

These print file guidelines reflect common printing industry standards, and detailed conditions can vary by item and method. O-SEAN confirms the conditions for each item at the quote stage.
