Even after the printing press was installed, we couldn’t have an instructor from overseas come, so we received instruction in setting up and operation remotely from the evening until about 8 pm. We also had a technician from SCREEN come and give us guidance.”Six people in charge of flexoIn addition to the printing presses, the Itoman Factory, which has flexo flexible packaging equipment, is equipped with an automatic flexo plate applicator, LaserClean’s Anilox laser cleaning machine “ALCS1000SFH”, COMEXI’s non solvent laminator “SL2MB”, a dual shaft take-up slitter “S2DS”, New IWASHO’s “TW-560N” inspection and rewinder (equipped with DAC ENGINEERING’s “TrinityTCC601-T2 (600)”), “PC-CW400III (GW)” high-speed center press bag making ma-chine, and “SDN-CH500TIIIS (W)” fully automatic tape inser-tion bag making machine.Currently, there are six peo-ple in charge of flexo (as of June 2022). Susumu Oshiro, factory manager, said, “For a long time, our main printing method was offset, so we never imagined that we would be printing on film. As I thought, everyone was inter-ested in water-based printing for flexible packaging with flexo. Even if the color is stable at first, it gradually became uneven after printing for a long time, so we had to change the resin plate and so on. It was not easy to stabilize and we had a hard time. So we decided to start where we could, with UV, but we still had trouble with odor and maintaining constant quality.” Recently, how-ever, these issues have been resolved, and the quality of the finished product is fine.Over 70% of work becomes wa-ter-based flexo relatedFA22 is a narrow-web combination press, capable of wa-ter-based and UV printing. Takeshi Uehara, deputy man-ager of the Flexographic Printing and Production Depart-ment, commented, “Currently, 70% to 80% of our work is water-based flexo printing. For UV, we can handle up to eight colors.” Currently, UV inks are made by TOYO INK and water-based inks by Dainichi-seika Color & Chemicals Mfg. For drying, each printing unit is equipped with a hot-air unit for water-based inks and an irradia-tion lamp for UV inks.The machine’s one-pass in-line processing capability for double-sided printing, cold foil, varnishing, and die-cutting of seals and labels was also a deciding factor in the decision to install the machine. For example, it is possible to make la-bels by printing, varnishing, and processing holograms with cold foil. Some of the inquiries we have received are about Factory Manager Susumu OshiroDeputy Manager Takeshi UeharaMembers in charge of flexoThe All New FA22”Flexographic 8-color machine “The All New FA22.” The turn bar is installed so that double-sided printing is possible.6
