の専用紙では、このような問題は極めて少ない。However, since letters and graphics are printed with water-based ink on such mail items such as New Year's cards, the water-based ink flows out due to rain or the like during mailing or delivery, and the letters and graphics are printed. In some cases, the printed matter becomes very unsightly, and in the worst case, the printed matter disappears. In particular, the spread of color printers has been accelerated, but when printed with a color printer, multicolor aqueous inks flow out and are mixed, which is extremely unsightly. In addition, such a problem is extremely small in the special paper for various printers.
