Methodology
How we buy, measure and score, step by step.
How we buy
- Every book is ordered on the same day, as a private person, to the same address.
- We record the list price and any promotion open to everyone that day.
- We record the screen from the photo upload to the payment, with a timer.
What we document
- Every e-mail and text, with date and time: confirmation, production, dispatch, delivery.
- The same question sent to every provider's support on the same day.
- The parcel's condition at the door, photographed before opening.
What we measure
- Colour, on the same reference chart, under the same D50 light.
- Page thickness with calipers, and the weight of the book.
- How much of the photo across the spine is lost, in millimetres.
- Days from order to door, against the promised window.
The blind panel
- 10–15 people from outside the team get the books with the logos covered.
- They score the cover, colour, paper and overall impression.
- The panel gives half of the print quality points.
Right of reply
- Every provider gets its review 7 days before publication.
- Its answer is published on the review page, unedited.
