SparkPrep checks your cover and interior files against the exact rules KDP, IngramSpark, and Barnes & Noble use to reject submissions — bleed, trim, CMYK, DPI, fonts, and more — then fixes what it can, before you upload.
You export a "final" file, upload it, and days later get a rejection email full of print terms you've never had to think about.
Built directly against KDP, IngramSpark, and B&N's real specification requirements.
Once these 50 spots are gone, this pricing never comes back. Every plan renews at this exact rate, every year, for as long as you stay subscribed.
Your access is annual. Your founding status is permanent — this cannot be purchased again once these 50 are gone.
