This cover is for a Lightning Source book. Here are their issues with density and spot colors.
• BLACK/RICH BLACK/DENSITY: We recommend a rich black with CMYK values = 60% Cyan / 40% Magenta / 40% Yellow / and 100% Black. Maximum density should not exceed 240%. Elements should not be built in ‘Registration’ (100% of all colors). For best results for text 24 pt. or below, please use100% black only. *Files sent with densities higher than 240% may be rejected for correction.
• SPOT COLORS/RGB: Please convert all spot colors (PMS / PANTONE) with/without transparencies to CMYK, (even in supporting .eps files). *Note: RGB files received will be converted to CMYK before printing. RGB / spot color with/without transparency may produce unexpected color results when printing. Any dissatisfaction with color shift will be the publisher’s responsibility to correct.
