Spot colors are widely used in the food packaging industry. We wish to add a watermark signal within a spot color that is readable by a Point Of Sale (POS) barcode scanner which typically has red illumination. Some spot colors such as blue, black and green reflect very little red light and are difficult to modulate with a watermark at low visibility to a human observer. The visibility measurements that have been made with the Digimarc watermark enables the selection of a complementary color to the base color which can be detected by a POS barcode scanner but is imperceptible at normal viewing distance.

Romanian children's literature, particularly translations for children, has rather low visibility in international children's literature scholarship, and translations of Beatrix Potter have not been extensively researched, either. This article contributes to filling these gaps by exploring the challenges involved in the recent publication of the first licensed Romanian edition of Beatrix Potter and the strategies employed to solve them. It identifies extra-textual challenges, related to the possibility of publishing Potter, the licensing process, the selection of particular tales and book formats for publication, and marketing strategies; and textual challenges, arising from Potter's writing style, the interdependence between visual and verbal aspects in her tales, their cultural specificity and read-aloud qualities. It also discusses the roles of the British and Romanian publishers in the publishing process and relates the translation strategies visible in the texts to the translator's apparently divided responsibility towards Potter and the Romanian audience, her conceptions of children and children's literature, and the Romanian literary tradition.

Thickness Variations

The manufacturing of high-quality extruded low-density polyethylene (PE) paperboard intended for the food packaging industry relies on manual, intrusive, and destructive off-line inspection by the process operators to assess the overall quality and functionality of the product. Defects such as cracks, pinholes, and local thickness variations in the coating can occur at any location in the reel, affecting the sealable property of the product. To detect these defects locally, imaging systems must discriminate between the substrate and the coating. We propose an active full-Stokes imaging polarimetry for the classification of the PE-coated paperboard and its substrate (before applying the PE coating) from industrially manufactured samples. The optical system is based on vertically polarized illumination and a novel full-Stokes imaging polarimetry camera system. From the various parameters obtained by polarimetry measurements, we propose implementing feature selection based on the distance correlation statistical method and, subsequently, the implementation of a support vector machine algorithm that uses a nonlinear Gaussian kernel function. Our implementation achieves 99.74% classification accuracy. An imaging polarimetry system with high spatial resolution and pixel-wise metrological characteristics to provide polarization information, capable of material classification, can be used for in-process control of manufacturing coated paperboard.

Immersion biotesting has long been used to challenge packages, particularly cans, for pinholes and channel leaks. Such testing for all types of plastic packaging may not be appropriate because some packages (e.g., aseptic, hot fill) are not exposed to water. As the food-packaging industry develops alternative environmental biotests there is a need to benchmark them against traditional immersion testing. The purpose of this research was to examine the threshold of critical-defect dimensions using artifically created channel leaks of 10 and 20 μm and 5- and 10-mm lengths sealed into plastic pouches which were subsequently tested by immersion at 102 and 106 CFU of motile and nonmotile Pseudomonas fragi TM849 per ml. Forty-four percent (44%) of the pouches tested became contaminated, indicating the threshold defect value is below 10 μm. Microbial ingress was significant (P < .05) for motile test organisms with a concentration of 106 CFU/ml. The interaction of concentration and time was also significant at 102 CFU/ml at 30 min exposure and 106 CFU/ml at 15 min. Channel length was not statistically significant. The markedly greater contamination rate using immersion testing versus that of aerosol testing highlights the importance of using test methods that reflect environmental exposure conditions of the packages.
