Operating Principle: CRC2OOO utilizes patented state-of-the-art video imaging technology. A typical arrangement consists of six print units printing on both sides of one web. Each print unit prints a unique mark on a surface of a substrate. Each printed surface of the substrate has an operator-specified area, consisting of a cluster of marks printed by respective units. Each time the cluster of marks passes under camera, a high-speed strobe illuminates the area for microseconds and image is grabbed with the camera. The CPU identifies the marks and calculates register error Correction motors are then activated for appropriate time for maintaining constant color register position.

Features:

• Each print unit prints unique marks. 0.02" X 0.02" size, on one surface of a substrate. Mark cluster on each surface requires a small clear area, 0.18" X 0.96".

• Mark cluster can be oriented across or along the web moving direction. This allows mark cluster to be positioned between pages, resulting in significant waste savings.

• Patented Shape Recognition allows detection of register marks through print scumming, resulting in fastest register pull up during make-ready.

• CRC2OOO further reduces waste by presetting a job to the operator-defined location. When locking units in AUTO mode, operator has three choices 1) To read and maintain current register relation. 2) To read and bring register relation to ideal locations. 3) To read and bring register relation according to the last run.

• CRC2OOO takes a snap shot of all marks printed by different print units. This feature eliminates false errors typically associated with web weave and sequential reading of marks printed along the running direction of the web, used by conventional controls.

• CRC2OOO is capable of sensing errors up to +0.001".

• Equipped with a unique SQM (Statistical Quality Monitoring) feature. CRC2OOO gives details about extreme errors and consistency of quality for each print unit for a user programmable sample size. This information can be useful in fine tuning different operating parameters on the press for optimizing overall efficiency. Graphical representation of the errors helps in Error Trend Analysis.

• A high-resolution 17" Color Touch Screen provides important information with a user friendly display scheme. All operator inputs are provided by touching ergonomically designed interface buttons on the screen. The screen only responds to human touch.

• Any print unit on a surface can be specified as a Master Unit. CRC2OOO maintains register position of all print units relative to the Master Unit. Master unit can be changed on the fly without losing current job setup.

• For multiple web presses the jobs can be easily set for different unit splits (example: 5+3 units, 4+4 units, etc.)

• Camera View feature opens a window on the touch screen to show the image grabbed by camera.

• CRC2OOO supports phaser motors for print unit to print unit timing.

• An unlimited number of job configurations can be saved for future use. Job files can be saved, loaded and erased with operator commands.

• Correction motors on all units printing on a surface can be temporarily paused without losing job setup.

• On-line context sensitive help is available at the touch of a button on the screen Help menus display extensive details about operation, maintenance and troubleshooting topics with detailed graphics.

• Individual print units can be switched to Manual Override mode for operator preferred corrections.

• A print unit can be designated as a non-printing unit to disable all register movements in manual and auto modes.

Setup and Maintenance:

• CRC2OOO is equipped with cylinder centering feature to center cylinders in both lateral and circumferential direction.

• Modular design of CRC2OOO allows easy swapping of components with minimum skills.

• Most components used in CRC2OOO are industry standards and are commercially available in open market through network of local vendors.

• On-line troubleshooting and software maintenance can be done remotely with modem and telephone line hookup.

• All parameters in CRC2OOO are adjusted digitally using touch screen. There is no need to hook-up oscilloscope and do the calibration. Full screen editing of the parameters make it extremely simple to change the parameters.

• Parameters have a multi-level password protection to provide access only to the authorized personnel.
