I've printed a few photobooks through various services (AdoramaPix, Blurb, etc.) and am always looking for better quality options. I hear good things about BayPhotos and Milk, in particular their 6-colour print. Unfortunately they don't seem to provide the option to design the pages with my own software. I'm thinking I could ignore this apparent limitation and create pages in Indesign and place them as full spread "photos" with their mandatory software.
My doubt is the following (besides not knowing the exact bleed etc. dimensions): if I add text to a layout and export the page as a jpg or tiff with sufficient resolution, will it make any difference in the printing of text compared to their recommended way of placing images and text as separate objects?
I am not familiar with printing technologies but I can imagine that text is sometimes printed in a separate process from images, and perhaps it results in sharper or otherwise better text rendering than treating it as mere pixels like any other photo. Am I overthinking this?
