Planning guidance
Print Prep Lab provides calculation tools and educational references for print planning. Results are not a production guarantee, printer certification or substitute for a physical proof supplied by a print provider.
Your production responsibility
Confirm final dimensions, bleed, safe area, color mode, profile, file format and resolution with the company producing the work. Provider-specific requirements take priority over general examples shown on this site.
Reasonable use
You may use the calculators for personal, educational and commercial print planning. Do not present the site's guidance as a guarantee issued by a third-party printer or standards body.
Advertising and external services
The site may display third-party advertising and link to external resources. Advertising, analytics, hosting and linked third-party services are responsible for their own content, availability, terms and privacy practices.
Changes and availability
Features, calculations and reference material may be corrected or updated when standards, provider guidance or site functionality changes. Print Prep Lab does not guarantee uninterrupted availability of every tool or external service.
Corrections and contact
Reproducible calculation errors and missing formats can be reported through the Contact page. A confirmed defect may be corrected across the calculator, related examples and reference pages; the public change history records the updated source.
