Book Mail: IngramSpark versus BookVault. For full colour children's books & picture books, print quality/paper options for IngramSpark are similar to Amazon, IngramSpark have a lot more trim sizes & are more flexible, particularly for hardcover. They also allow you to do preorder campaigns. You can't beat Amazon for reach & delivery speed (after publishing), but proofs were very quick with BookVault. The way my book from BookVault looks was a surprise! I'll continue to work with all three as they have their individual strengths. #childrensbook #childrensbookauthor #kidsbooks #babybook #babybooks #booksforkids #kdp #ingramspark #bookvault #amazonkdp #amazonbooks
