Abstract
An adhesive sealing strip for coiled or spooled recording materials, such as rolls of magnetic tape, in which the identification features, such as casting numbers, are clearly legible, is obtained by printing the features on an adhesive tape over the entire width of the web in lines one above the other and at the same time side by side in columns, each following column being offset vertically relative to the preceding column by a specific amount, whereupon the recording material is cut to the desired useful width. In this manner, a maximum height of printing of the identification features can be achieved in which the symbols are clearly legible (FIG. 3).
