What Does ‘Archival Quality’ Mean?
For a quick overview on archival quality prints, take a look at our FAQ page. There are many terms used to describe the archival quality of inkjet papers and every artist wants their work to stand the test of time. The problem is that there are many contributing factors when considering the archival quality of an image printed on inkjet fine art paper. The first thing to consider is the paper itself The term acid free has long been associated with archival quality when it comes to paper, but historically this terminology has only applied to the base paper without any type of coating applied. The base material should be manufactured using pure alpha cellulose fibre, pure cotton fibre or a combination of these two materials. This will ensure that the paper base is pH 7 or above (acid free). A paper that contains lignin cannot be acid free as lignin is a naturally occurring acid within plant fibres. It is the lignin content in newsprint paper which causes it to yellow and go brittle over time. For inkjet papers the coating must also be considered in combination with the base materials. The coating is applied to the surface of the paper base to ensure that the ink is absorbed just the right amount. Once a coating is applied, the pH value (acidity) of the entire paper changes. The only way for this to be addressed is for manufacturers to ensure that the coatings used on their papers are as close to acid neutral as possible and to supply the pH value of the total paper (base and coating) rather than just the base. The second thing to consider is how the image is printed [...]
