The lightfastness of prints is an extremely important characteristic for assessing their print stability. The fastness properties of prints can be described in terms of print durability and image stability. Good lightfastness assures the good print stability after long use. This study has focused to describe the lightfastness of printed foil samples due to long time exposure. It may also be used for the authenticity or validity of the product. Moreover, any kind of deterioration in package print quality will affect the sale value of the product adversely. Little work has been done to study the fastness properties of printed films and foils. In this work, blister foils printed in the gravure printing process are taken as the sample as it has extensive usage in food and medicine packaging. The samples are exposed in artificial lightfastness tester BGD 865/A Bench Xenon Test Chamber (B-SUN) for assessing the light fastness of cyan, magenta, yellow and black ink on the foil. The spectral curves and colorimetric values of prints are measured in the ocean optics spectroradiometer (DH2000BAL) before and after exposure. An Artificial Neural Network model (ANN) is proposed to predict the fading rate of the printed foil. The optimal model gives excellent prediction with the minimum mean square error (MSE) for each color and a correlation coefficient of 0.98-0.99.

  • The IS&T (digital) Archiving Conference offers a unique opportunity for imaging scientists and those working in the cultural heritage community (curators, archivists, librarians, photographers etc) from around the world to come together to discuss the most pressing issues related to the digital preservation and stewardship of hardcopy, and other cultural heritage documents and objects. Authors come from museums, archives, libraries, government institutions, industry and academia. Cutting edge topics related to multispectral and 3D imaging, as well as best practices for workflow, sharing, standards, and asset/collection management and dissemination are explored in papers presented at this annual, international event.

    Please note: For purposes of its Digital Library content, IS&T defines Open Access as papers that will be downloadable in their entirety for free in pertuity. Copyright restrictions on papers vary; see individual paper for details.
