This article provides a list of standard papers/materials used in the manufacturing of Lightning Source printed books for IngramSpark.
The specific papers/materials used in the manufacturing process are determined by the mill sourced, trim size and/or bind type selected at the time of title setup and file submission.
This list is subject to update without notice. Publishers are encouraged to check back here periodically to verify certified papers.
We only have one Earth, and Lightning Source takes measures to treat it well.
The purpose of print-on-demand book manufacturing is to reduce our environmental impact. Traditional offset printing usually requires large orders in anticipation of sales. Often, any books that go unsold are destroyed. This results in wasted paper, wasted energy, added greenhouse emissions, pulping, and landfill overflows.
At Lightning Source, books are printed in ultra-short runs or only when an order has been received. This print on demand model of book manufacturing reduces supply chain waste, greenhouse emissions, and conserves valuable natural resources.
Lightning Source expects each of its paper suppliers to be environmentally responsible as well, and not use papers sourced from endangered old-growth forests, forests of exceptional conservation value, or the Amazon Basin.
