Contact PrintCalcHub

Have a question about PrintCalcHub, found a calculator issue, or want to suggest a printing calculation we should cover? Email the PrintCalcHub Editorial Team at contact@printcalchub.com.

Calculator Corrections

For a calculator issue, please include the calculator name or page URL, every value and unit you entered, the result you received, and the result you expected. A reproducible example helps us review the calculation efficiently.

Editorial Feedback

For a guide or article correction, identify the page and the specific statement that needs review. Where possible, include relevant manufacturer documentation, a technical standard, supplier specification, or another reliable source that supports the correction.

Business and General Enquiries

For website feedback, collaboration enquiries, legitimate business matters, or general questions, email contact@printcalchub.com. Please do not send passwords, payment-card information, confidential production files, regulated personal data, or other sensitive information by email.

What to Include

A useful message includes the page URL, a short description of the issue or request, and enough non-sensitive detail for us to understand the context. For calculator questions, include the exact units because unit selection can materially affect a production result.
