For anyone who uses print-on-demand outfits such as Lulu.com, or who has been considering doing so, Cathi points out the following brilliance:
“Dear Lulu” is a test book researched and produced by graphic design students and Prof. Frank Philippin at Hochschule Darmstadt, Germany, during an intensive two-day workshop with London-based designer James Goggin (Practise). The book’s intention is to act as a calibration document for testing colour, pattern, format, texture and typography.
Exercises in colour profile (Adobe RGB/sRGB/CMYK/Greyscale), halftoning, point size, line, geometry, skin tone, colour texture, cropping and print finishing provide useful data for other designers and self-publishers to judge the possibilities and quality of online print-on-demand — specifically Lulu.com, with this edition.
The book’s price is set at Lulu.com’s exact printing cost per unit.
The book is CC-licensed, in case you want to make your own version. (It is also, as the photos above indicate, cute as a button.) And be sure to check out the helpful reviews under it—including one from Lulu.
