What is a Printograph?
I personally make my printographs based on my original art. Technically, the printographs are not lithographs, but produced using modern technology, involving scanning, manual adjustments of the colors to make up for the different color spaces used in different devices, and finally printing on an advanced digital printer. Each printograph may be signed and dated.
The visual quality of the printographs is amazing. The colors are vibrant. Each brush stroke of the original painting appears in a high quality on the printograph. Thus, when framed with a matboard (passepartout) the printographs look very much like real paintings. Read here for details on the sizes of the printographs.
Be aware that the images shown on the Web are NOT of the same high quality as the final printographs, so you will not be able to print them yourself in the same vibrant color quality or with the details that appear on the printograph. The printed versions are clearer and brighter than what you see on the Web. Furthermore, the images on the Web are stamped with a copyright notice which does not appear on the final printographs.
Using the current printing method, the printographs are NOT fully of archival quality (which is meassured in 50-100 years or more). In general, the longevity is dependent on the specific combination of ink and paper. The inks currently used are water based, and the colors will fade over time when exposed to light, oxygen, low humidity and heat. It is not recommended to expose the printographs to direct sunlight, at least not without a glass cover.
The technology for archival (long lasting) quality has become available. I follow the development of the technology and may soon upgrade to a digital image printer that supports an archival combination of ink and paper.
