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.
Therefore, direct thermal labels are primarily used for short duration applications, such as shipping labels. On the other hand, thermal transfer printers use heat to transfer ink from ribbon onto the label for a permanent print. Some thermal transfer printers are also capable of direct thermal printing. Using a PVC vinyl can increase the longevity of the label life as seen in pipe markers and industrial safety labels found in much of the market place today. There are three grades of ribbon for use with thermal transfer printers.
