I have received inquiries regarding our papers and want to ensure you that all DCWV paper products are acid-free and lignin-free. We continuously test and sample our papers for acid free pH levels to ensure that we are offering products that meet the acid-free requirements for archiving your memories in craft projects. Our testing is conducted using digital pH monitors as well as independent testing facilities. Although there are some inconsistencies in the standards that are required to claim acid-free or archival-safe, our products continue to meet the guidelines available. After an extensive study on pH levels and their effects on paper, we require that all of our paper products have a pH range between 6.5 and 8.5 and a lignin content of less than 1%. This range falls between The Library of Congress standards (7.5 to 10) and the CK/OK standards (6.5 to 8).
One of the best reports that I have read on acid-free standards is from HP. This report gives their findings on the current guidelines and also mentions scrapbooking and acid-free test pens specifically and provides some great insight. Please see below for their comments on pH test pens. For the full report, please visit: www.hp.com/sbso/product/supplies /paper/images/acid_lign...
“Numerous tests by HP concluded that the most commonly available ‘pH test pens’ yielded conflicting results depending on the brand of the test pen. These tests also gave misleading information such as the indication that some coated papers contained acid when in fact they did not. If archivability standards were better defined and applied, consumers would only need to refer to the manufacturer’s specifications and not rely on third party suppliers.”
You may want to contact your pen manufacturer to obtain their pen specifications.
As one of the largest paper manufacturers in the craft industry, we consider the archival qualities of our papers and your crafts to be our highest priority. We ensure our paper products are acid-free and lignin-free.
Please let me know if you have any questions or comments.
