Introducing the Ryobi 755 – B2 Press

As an addition to our ever growing fleet of high quality machines, Callprint have recently installed a Ryobi 755 – B2 Press. We feel that the lithographic market is continuing to grow despite the advances of digital machines, and that the installation of the Ryobi will compliment the digital work that we currently produce. please read through the benefits that this new device will give to our customers.

What does this mean to you?

Size - Wider printing area

The RYOBI 750 Series comes with a maximum printing area of 765 x 545 mm (30.12” x 21.46”) ,

Paper – More flexible range

The press can flexibly handle a wide range of paper from 0.04mm (0.0016”) onion skin to 0.8mm (0.031”) thick cardboard or standard paper ranges from 60gsm to 450gsm.

Speed – Quality and quantity

Printing speed is assured at the high speeds of 15,000 B2 sheets per hour (60,000 A4 per hour). With the advantage of the Non-stop Feeder, paper can be continually fed whilst the Press continues to print.

Colour – 5 colour

Now we have the flexibility of printing 5 colour, 4 colour plus one spot colour, 5 down to 1 spot colours.

Speed and Productivity – Inline Coating System

Take advantage of Aqueous coating with the Inline Coating System. In addition to adding value to printed materials, such as surface protection and glossy finishes, the Inline Coating System also shortens drying time, which offers shorter delivery time.

Speed and Productivity – Infrared Dryer

We can now boost productivity with the Infrared Dryer unit which is installed on the Press. The Dryer provides an extremely quick drying solution which enable’s shorter delivery times and the capability of being able to handle printed sheets for finishing at a much quicker rate than standard processes.

Speed and Productivity - Semi Automatic Plate Changing

RYOBI semiautomatic plate changer allows the printing plate to be changed easily and accurately with simple push button operation, there by drastically reducing the make-ready time and improving productivity. The operator merely sets the plate on the positioning pins and presses a button.

Quality - RYOBI-matic-D Continuous Dampening System

The RYOBI-matic-D continuous dampening system assures a uniform dampening supply on the plate surface to reproduce sharp halftone dots, glossy solids and finely detailed text. Starting is quick and this system is designed to minimize wasted sheets. The dampening system substantially reduces hickeys on plates by adopting a new drive mechanism for the water form roller.

Quality and Speed – High speed infeed mechanism

By utilising an underswing and drop-away front lay infeed system – high registration accuracy is maintained even during high speed operation at 15,000 sheets per hour.

Quality and Control – Auto Print Density Control System

Utilising the Auto Print Density Control System enables you to measure the colour bar of the printed sheet using the spectrophotometer, offering the ability to automatically correct colour densities to match the correct printed sheet. The system calculates and provides a feedback to the machine which then appropriately adjusts the openings of the ink fountain keys. Quality control is now achieved using precise numerical values, contributing to consistent quality printing.

Quality and Control – Ink Volume Setter Software

The printed image area ratio data is calculated by the Ink Volume Setter Software. Using the data created offers the advantage to preset the Ink Fountain keys on the Press. Effective use of Pre-Press data dramatically reduces the labour and time prior to printing production.

Quality and Control – Digital Workflow

An optimised Digital Workflow enables smooth connection of Pre-press, Printing and Post-press Operations as well as consistent control with our JDF compliant management system. Our information Digital Workflow System handles everything from receipt of order to delivery of printed material.

Environment – The Greener Option

The Ryobi 755 has the advantage of using vegetable based inks and alcohol free fount solutions. All printing plates are produced on a ‘Processless’ Computer to Plate System. In partnership with Ryobi we can apply operating practices and procedures which will help in the protection of the environment.
