RNP 2000

OFFSET rotary press HELIO rotary press FLEXO rotary press ROTATIVE cut Unit Under Recovery PLATE cutting

RNP2000 is designed in such a way as to transfer to the software level all the variable parameters that normally define the different types of color registration systems available on the market. One unique characteristics of this system is that it incorporates all the software functions to keep track of the various jobs carried out on the rotary presses and guarantee that the operating quality is followed through.

Therefore, with the RNP2000 system, each specific application no longer calls for the implementation of specific equipment, representing a major gain for the user in terms of:

The registration system consists of:

• A supervision and programming unit
• A user mini console
• A calculation CPU
• Interconnection interfaces with web scanners and motors

• Number of control units : 12
• Lateral and/or longitudinal testing
• Configurable by unit for web/web or web/Cylinder
• Correction on differential or by register for each unit
• Possibility of taking format variation into consideration
• Automatic presetting
• Backup and recovery of prior jobs
• Alarm on maximum error per printing unit
• Centralized testing by touch-sensitive screen
• Quick control mini-console
• Remote control on printing unit
• "Auto gain" type web scanner

This unit covers the following functions

• determination of scanner reading windows
• access to working parameters
• error display
• error real-time analysis

For each registration unit, it is possible to set the read enable zone to 1/100 mm of the format for its position and range. This setting can be obtained at a stop or in real time.
Spot reading materialization allows fast setting.
Unique possibility of using the printout as a registration spot.

• Indication of web speed
• Indication of correction direction
• Indication for manual/automatic correction
• Indication of longitudinal deviations
• Indication of lateral deviations

This menu gives access to all the RNP2000 functions either in using the touch-sensitive screen or a combination of mouse/keypad.

The display and control of the reading areas requires the format values of the various units.

The possibility of attributing the various spot readers to the correction units avoids having to reposition the readers in the event of work using various web passages.

This window is used for displaying and modifying the computer parameters, unit by unit. This particularity is a way of using the same units, for example, for testing a printout or a rotary cut. All the parameters can be backed up to a file and called up for future jobs.

This mini-console allows quick action thanks to a specific keypad and to LCD displays for the most important system parameters, in particular: display of longitudinal and lateral deviations manual offset of printout by unit on/off control by unit, longitudinal and lateral registration spot reading display rapid modification of one of the test parameters.

on off control unit

This function is used for real-time representation of longitudinal and lateral registration error by unit.
These data are a way of refining the setting of the test loop parameter and it is also possible to store errors on a hard disk for a given job.
A file will be created registering the error values and the machine parameters used. These files can be analysed using EXCEL.

In web/web configuration

Possibility of correction on differential

Note: after electronic multiplication by 4 encoder pulses, each pulse represents 1/100 mm on the web of paper.

• Compact metal case with adjustable connector
• LED white light source (long life).

• Reading of all the colours in the visible spectrum
• "Automatic" or "Manual" sensitivity adjustment, at remote or locally
• Reading on film, aluminium, etc.
• Response time < 1us
• Spot 4 mm X 0.7 mm
• Focal length 12 mm.
