I have been using two different printers for photo books for the past several years. I tend to use Printique (formerly AdoramaPix) for my "serious" books, those where I anticipate wanting full spread images and top quality printed images.
I also like using Mixbook. I find it easier to use and less expensive, though the lack of a practical lay flat option and my perception of their print quality keeps me from using them for books where I know I have top notch images.
Covid-19 has me delving into my archives to create new books of events well in the past. Mixbook is the right choice for me on these as:
- My images back then tended to be a bit off -- no need for big prints.
- Ease of book creation is more important given potential volume and time constraints.
- Lower cost encourages more generous allocation of pages for marginal materials.
- Thinner finished size takes less bookshelf space.
