A summary of the results is given here. Results observed included compound-related, non-neoplastic lesions of the thyroid in both sexes of rats and mice including follicular cysts and hyperplasia. An increase in the incidence of thyroid neoplasms was observed in the high-dose groups compared to control groups for both sexes of both species.
A thermal printer. Thermal printing (or direct thermal printing) is a digital printing process which produces a printed image by selectively heating coated thermochromic paper, or thermal paper as it is commonly known, when the paper passes over the thermal print head. The coating turns black in the areas where it is heated, producing an image.
Direct thermal printers. Direct thermal printers require the use of heat activated thermal papers and films, but require no transfer ribbon. The print color is limited to black, unless special, preprinted direct thermal paper is utilized, and the printing is not as crisp as that of thermal transfer ribbon printing. Over time the labels will darken, particularly when the surface gets scratched, or is subjected to heat and sunlight.
