Useful for evaluating processing distribution, which was difficult to determine with wet reagents! Introducing our technical data.
Three PLAZMARK labels were attached to plastic writing instruments and subjected to corona treatment, followed by visual inspection of the discoloration of the indicators and color difference measurement. As equipment, corona discharge was used for pre-treatment before printing on plastic writing instruments. Traditionally, a wet reagent was used for inspection at the start of operations, and if the values were outside the standard, the output value was increased, or the wire electrodes were cleaned and adjusted. As a result, the color difference was small, but it was possible to visually distinguish the intensity, making it useful for evaluating treatment distribution, which was difficult to assess with the wet reagent.
