Print Settings and File Preparation for E1
Paper Dimensions and Resolution Guidelines
Set your document to 90 x 126 mm and use 300 DPI for sharp text and graphics. Avoid scaling issues by locking aspect ratios and using vector-based logos where possible.
Color Profiles and Bleed Requirements
For professional prints, switch to CMYK, include a 3 mm bleed if graphics touch the edge, and export with appropriate marks for trimming to ensure consistent results across print partners.
Design Considerations for E1 Format
Typography and Readability
Choose clear typefaces, maintain strong contrast, and set line spacing that suits the compact width. Keep margins generous to prevent text from feeling cramped on small displays and printed cards.
Visual Hierarchy and Branding
Place your logo and key message in the upper area, use concise bullet points for benefits, and align contact details to a consistent baseline so recipients can scan the content quickly.

Event Invitations and Reply Cards
E1 is popular for weddings, small gatherings, and RSVP campaigns because it fits neatly into corresponding envelopes while still providing room for a short program or seating notes.
Direct Mail and Notices
Businesses use E1 for concise promotions, appointment reminders, and feedback requests, where a compact format keeps postage low and response rates high due to clear, focused messaging.
