Lob’s general guidelines around custom outer letter envelopes are detailed below:
Image Format
- Preferred: .pdf
- Secondary: .ai, .indd, .psd
Artwork Considerations
- Outline all fonts
- Differences in kerning, font versions, anti-aliasing, etc. can cause small differences between what you see on your screen and what we output to press
- Double check that all images are embedded into your document
- Please ensure all rasterized artwork (images, effects, copy, etc.) is created and saved at or above 300 DPI
- All images must be at or under 25% ink saturation
- Type should be no smaller than 5 pt
- Thin, small fonts with over 3 colors may fill in slightly or appear “fuzzy”
- Line weights of 0.5 pt or more assure optimum print results
- It is preferred that barcodes/QR codes are vector/editable
- CMYK documents are preferred over RGB
- Converting RGB documents to CMYK may cause an unexpected difference in color
- Other design elements: available on a case-by-case basis
- Please reach out to our Sales team for additional information
Layout Considerations
- Bleeds should extend 0.125” past trim line
- Any other artwork should be 0.125” away from trim line due to movement at press
- Custom outer envelope design template
