CTP(7900) (Computer to Plate) Explanation
What is the 7900CTP
The Epson 7900CTP system is designed to create Press Plates for offset printing. It requires the use of Epson
Directplate Aluminum Plates. The Epson Directplate Aluminum Plates have a coating that accept ink until they
are cured (heated). After curing, the area of the Plate that has not been “inked” will reject press ink. The area that
was inked before curing will accept ink, and transfer it to the media during the printing process.
Items included with the 7900CTP
Epson Stylus Pro 7900 printer
EFI RIP software for creating the separation images.
Plate Curing Unit (PCU) for heating the plates.
Plate Guide to ensure linear loading of the plates into the 7900.
Epson DirectPlate Aluminum sample pack for aligning the Plate Guide.
Hexagonal (Allen) (2.5 mm) wrench for attaching the Plate Guide.
Hexagonal (Allen) (5 mm) wrench for attaching the Plate Guide (also used for assembling the 7900 printer stand).

Service Implications
7900
The 7900 Printer included with the 7900CTP system is the same 7900 that is sold separately. Servicing the Printer
is exactly the same with one exception.
After removing the any of the Right Side Cover Components, the Plate Guide alignment must be adjusted. Direc-
tions on how to perform the Plate Guide alignment is located in the Adjustment Section of the Field Repair Guide.
