User-Friendly Operation Thanks to Automation

User-Friendly Operation Thanks to Automation

The RYOBI 3404DI is loaded with automated processes, from plate advance and imaging to making color adjustments— operations that once required high levels of experience and skill. Its user-friendliness ensures that even operators with little experience can achieve quality printing in a short period of time.

Simple, Straightforward Centralized Control from the Operation Stand

All major operations for the RYOBI 3404DI are initiated and controlled from the operation stand. Setting the number of printed sheets; job data entry, interruption and recall; presetting the ink fountain keys; and cleaning are all centrally controlled from the operator’s position. A large- format 14.1-inch LCD ensures user-friendly operation.

Automatic Ink Fountain Key Presets

Calculating the image area ratio for each color is done simultaneously with imaging. Presetting the ink fountain key is done automatically from the operation stand based on this data.This allows easy control of the ink fountain key opening volume, dramatically reducing the time and effort involved in making color adjustments.

RYOBI Program Inking

RYOBI Program Inking automatically supplies ink to the ink rollers to match the image from the very start of printing. After the set number of prints is finished, the ink on the rollers is auto- matically restored to an even state, allowing the operator to proceed quickly to the next job and minimizing the amount of wasted paper generated at the start of printing.

Convenient

Auto Print Function

The RYOBI 3404DI features a convenient Auto Print function. Printing operations start just by selecting the Auto Print command on the operation stand’s monitor screen. Plate advancing, imaging, printing and blanket cleaning are all carried out at a click of a button.

Automatic Cleaning

Devices

The RYOBI 3404DI comes

standard with an automated cleaning system for both ink rollers and blankets (including an impres- sion cylinder cleaning function).This reduces the cleaning time required when switching jobs, thus lessening the workload for the operator.

RYOBI PDS-E

Printing Density Control System (option)

The RYOBI PDS-E Printing Density Control System is an option on the 3404DI. Color adjustments previously based on the experience and intuition of the operator can now be made using numerical values from solids densities calculated for each color.This system allows the operator to easily match printing output to the OK sheet and keep quality consistent.
