I think I'd like to emphasize the abbreviation "EQ" in big, bold letters--making that a main feature. Colors are often used to symbolize emotions. So another idea is "EQ" in big block multicolored letters? Or, a more abstract use of color as a background to the letters "EQ"?
These are just ideas, look forward to seeing what designers come up with, too.
I've also included a sketch of an initial idea for the cover; feel free to play around with this design.
Here are some specs from my publisher:
The fonts used on the interior for the book are:
Hoefler & Co Archer (https://www.typography.com/fonts/ar…/overview/)
Commercial Design Graphik (https://commercialtype.com/catalog/graphik)
A2 Type Register (https://www.a2-type.co.uk/register)
We’ve used some different fonts on some of our cover designs, so it’s not crucial they use these - mostly, I would recommend just keeping the look and feel of the interior in mind when designing the cover.
For the actual cover, we would need an InDesign file, and an accompanying IDML file, along with files for all fonts and any linked graphics. File size should be 5.5” w x 8.5” h, with a 1/8” bleed on all four sides. The design should be created in InDesign, not in other software; other software (such as Photoshop and Illustrator) can be used to create linked graphics, if needed.
All files should be prepared using CMYK colours only (not RGB, not Pantone spot colours). No colour should have a total ink percentage greater than 240%. Any linked raster graphics must be at least 300 dpi at final output size. Any linked vector graphics should be Adobe Illustrator EPS or AI files.
All type must be editable, and must be created in InDesign - it can’t be converted to outlines, and can’t be imported from Photoshop, Illustrator, or other software.
