At Print 09 we introduced in addtion to our core solutions 4 new products:

·         ColorSpec – On Press Closed Loop color control
·         ColorInSpec – On Press Full sheet inspection
·         Adelphi AutoKey – Interface for Closed Loop Control
·         Adelphi AutoSet – Preset Interface
ColorSpec and ColorInSpec are products based on technology developed by Apollo Systems.
 
Apollo has over 200 inspection systems installed in highly demanding currency and security printing.
 
EPG is now bringing this advanced technology to commercial printing.
 
ColorSpec:
 
Closed Loop Color Control is not new but our approach is.
 
We combine line scan camera technology with the processing power of Sun Microsystem servers.
 
This enables us to read the entire color bar – 1 shot – every sheet – real time
 
Couple with this is our ability to lock on to the color bar as soon as black ink is laid down – without regard to registration.
 
This enables us to monitor startup density as it stabilizes across the sheet – sheet by sheet – and begin color correction at the earliest possible point.
 
Our ability to read the full color bar on every sheet also enables us to monitor the result of automatic ink key adjustment as it takes effect and make mid-course corrections to avoid under/overshoot.
 
Combined these unique capabilities enable KeyColor ColorSpec to get to color faster than any other closed loop system.
 
ColorInSpec:
 
Even more unique is our ability to upgrade ColorSpec to provide closed loop color control and full sheet inspection – every sheet – real time
 
ColorInSpec will detect defects and color drift in up to 300 separate user defined regions anywhere on the sheet.
 
The pressman specifies the OK sheet or series of sheets and each and every sheet thereafter is compared on a pixel by pixel basis to the standard.
 
Any deviation from the standard, slurs, ghosting, streaks, hickies, color drift is recognized
 
These deviations are shown on a reverse mask of the image, with color of the defect indicating severity of the deviation from standard
 
The objective is to enable the pressman to see defects developing in time to take corrective action – before they become rejects.
 
We also provide the pressman the ability to assign different tolerances for defects in each area. This combined with our pixel by pixel evaluation of each sheet enables us to achieve a false reject
rate of less than ½ of 1 %.
 
Adelphi AutoKey:
 
 This interface device allows us to link ColorSpec or any other scanning device to ink control systems other than KeyColor to provide Closed Loop Color Control
 
Adelphi AutoSet:
 
Provides presetting capability for ink control systems other than KeyColor
