Two possible covers with a different use of text and images. For now, I’m only showing two because it’s clear there’s a lot more variations to explore within the given restrictions (being: two colors, A5 format).
Also cool: today I’ve updated the list of pantone colors corresponding to the colors of the riso printer at Risiko Press, and I’ve found a way to put images into monotone pictures without the use of Photoshop. Previously I scanned the images, then imported them into PS, converted them to greyscale images, and converted them again to monotone/duotone/etc. images. Now, I just scan them as black and white images, and select a spot color in inDesign. Easy as pie.
