Introduction
The Epson Stylus®Pro 7900CTP Computer to Plate System enables small business printers to print
Epson DirectPlate Aluminum plates to run on their presses.
To run a print job on the system:
• Computer-separated images are produced with the RIP software
• The images are printed on a plate
• The plate is heated in a plate curing unit
• The plate is mounted on a press
• The job is printed
System Workflow
The workflow for the process is as follows:
4 | PCU Safety Instructions
PCU Safety Instructions
Before using your PCU, read the following safety instructions to make sure you use the equipment safely
and effectively.
• The electronics and heating element use dangerous electrical voltages. To reduce the chance of
personal injury or property damage, turn off and unplug the PCU when maintaining the system.
• Always turn off the PCU using the Heater switch on the control panel first. When the PCU
temperature reads less than 100
of the unit. Failure to follow this could result in a shortening of the life of the mechanism that moves
the plate through the PCU.
• The PCU heater reaches high temperatures during plate curing. Do not touch the slot area where the
plate comes out on the tray.
°C it is safe to turn off the PCU by the main power switch in the back
• Aluminum plates are hot when they exit the PCU. Let the plate cool before removing from the tray.
• Make sure the plate is dry when feeding it into the PCU; if the plate is wet, it could create steam and
cause burns.
• Do not open the PCU because of electric shock danger.
• Do not run the PCU with the protective cover open or removed.
• Place the PCU on a flat, level, stable surface that is larger than the unit. The PCU will not operate
properly if it is tilted or at an angle.
• The PCU weighs about 55 lb (25 kg) in the box and is bulky, so it should be handled by two people.
• Do not disable the safety mechanisms installed by the manufacturer in the PCU.
See additional safety instructions for the printer in the Epson Stylus Pro 7900/9900 Printer Guide.

7. Place the test plate on the input tray with the long edge toward the slot, coated side up, and gently
push it in so it engages with the roller. The plate feeds through the PCU at the set speed.
If the plate is not pulled in by the roller, check that the feed direction switch on the side of the PCU is
set correctly.
8. Check the indicated temperature on the temperature strips as the test plate leaves the PCU to see if it
is in the range of 150 to 160
°C. If the temperature is low, decrease the speed; if you see burning or the
temperature is high, increase the speed.
Installing the Plate Guide on the Printer | 13
Caution:
The transport belt should be kept moving when the heater is turned on. This reduces the surface temperature of
of the transport belt and improves belt life.
Always turn off the Heater switch on the control panel before you turn off the main power switch. Let the PCU
cool to 100 °C or less, according to the current temperature indicator, before turning off the power switch.
WARNING:
Aluminum plates are hot when they exit the PCU. Let the plate cool before removing it from the tray to avoid
burns. Use of gloves is recommended to avoid injury.
Installing the Plate Guide on the Printer
To assure proper registration when printing on Epson DirectPlate Aluminum plates, you need to install
the plate guide on the printer.
1. Open the roll paper cover on the printer.
2. Remove the roll paper if installed, to have room to attach the screws on the plate guide. See the
Epson Stylus Pro 7900/9900 Printer Guide for more information.
3. Slide the plate guide onto the right side of the roll paper cover, aligning it snugly with the black edge
of the roll paper cover.

Aligning the Plate Guide
The plate guide must be correctly aligned to remove any skew when printing on the plate. Otherwise, you
will have registration problems on the press.
1. Close the printer’s roll paper cover.
2. Make sure the fixing pin firmly touches the black plastic cover component. If it is not secure, loosen
the nut, extend the pin, and then tighten the nut.
3. Insert a test plate and print the file “7900CTP_alignment_sheet.pdf” that is included on the CD or
downloaded from www.proimaging.epson.com. (See “Loading a Plate in the Printer” on page 19.)
The included EFI RIP has a menu option that prints this file automatically.
Note:
You must use an Epson DirectPlate Aluminum plate (12

point A on the printed plate. Then measure the distance from the left edge of the plate to point B. If
the distances to points A and B are equal, go to step 7. If they vary by more than 1.0 mm, the plate
guide is not correctly aligned. Continue with step 5 to adjust the alignment.
Note:
For best results, use a ruler delineated in half-millimeter increments and a magnifying lens.

Note:
Since you will use multiple plates consecutively on the printing press, it is best to load plates into the printer in
the same direction each time. If this is not done, there is a slight possibility of minor differences in final printing.
Unloading a Plate from the Printer
After printing is finished, the plate stays in the printer. To prevent damage to the plate, make sure it
doesn’t fall. Hold the plate and do one of the following:
• If you plan to print more plates, press the Paper release (ePlaten) button. The plate currently in
the printer is released and you can load another plate.
• If you’re done printing plates, press the d button.
Using the PCU
After a plate is printed and prior to punching or loading it on the press, the plate must be run through the
plate curing unit.
1. Turn on the power switch from the rear of the unit. This activates the transport belt.

5. Once the PCU reaches the set temperature of 190 °C, place the plate on the input tray and push it so
it engages with the roller. The plate feeds through the oven at the set speed.
If the plate is not pulled in by the roller assembly, check that the feed direction switch on the side of
the PCU is set for the direction you want the transport belt to move.
Caution:
The transport belt should be kept moving when the heater is turned on. This reduces the temperature of the
surface of the transport belt and improves belt life.
Never turn off the power switch on the PCU without first turning off the Heater switch. When you turn off the
system, first turn off the PCU by pressing the Heater switch and let it cool to 100 °C (or less) before turning off
the power switch.

Plate Curing Tips
The requirements for curing can vary with temperature, humidity, and altitude. If you don’t get the
number of impressions you expect, you may need to adjust the cure rate. You can usually achieve the best
results with lower surface temperatures and decreased speed for less media distortion and a higher number
of impressions. See “Calibrating the PCU” on page 11 for details.
Note:
Remember that the optimal settings on the control panel are 190 °C with a speed of 1.5.
Punching the Plate
Before printing, use an offline punch to create necessary guides on the plate for the press. See your press
documentation or contact your Epson Authorized Reseller if you don’t have a offline punch.
Press Tips
This section includes recommendations on optimizing use of the Epson DirectPlate Aluminum plates. If
you currently use polyester plates, Epson DirectPlate Aluminum plates use similar dampening solutions
and cleaners.
Epson DirectPlate Aluminum plates have a different structure than conventional aluminum plates, and
require a longer time and more water to obtain a properly wetted surface.
Fountain Solutions
When the press starts up, the Epson DirectPlate Aluminum plates require more water than conventional
metal plates. You should provide about 30 seconds of pre-dampening before turning on the ink rollers.
Coat the plate with a layer of fountain solution as you load the plate to speed up the process.
The following fountain solutions are recommended (not carried by Epson):
• Prisco Fount Concentrate 142-126
• Agfa G671c
• Varn Universal Pink
Note:
If you use other fountain solutions, make sure they are alcohol-free.
24 | Cleaning Plates
Dampening Tips
• If a transition roller connects the dampening system and the inking system (e.g., ALCOLOR and
other similar continuous-feed dampening systems), deactivate the transition roller.
• If the printing press has a pre-dampening function (for example, the Heidelberg Printmaster QM), set
a higher pre-dampening level.
• If there are short breaks during the setup phase, or when the paper stack is being replaced, you should
leave the dampening rollers engaged on the tray. If this is not possible, restart printing in the same
manner as in the initial start-up procedure.
Ink Tips
• For best results, use highly pigmented inks to keep the amount of transferred ink at a low level and
decrease the scumming effect.
• For optimum printing quality, do not mix ink with printing oil or any other printing agents that
decrease tackiness.
Cleaning Plates
The following plate cleaners are recommended (not carried by Epson):
• HYDRO CLEAN
™

Correcting Plates
You can delete images with IWATSU Elotax Corrector OX-1. You can also use AGFA Lithostar
Copyrapid Correction Pen. Also, a pencil eraser works well to delete a small section from an image.
Reusing Plates
Epson DirectPlate Aluminum plates can be reused if you would like to store them for use again to reprint
the job.
If you plan to reuse a plate:
1. Remove ink from it by printing 20 to 30 impressions after disengaging the ink rollers from the plate.
2. Wash the plate with water before removal from the press.
Gumming or other special treatment is not required for reusing the plate. Store the plates in a dry, cool
place.
Washing the Press
The following press washes are recommended (not carried by Epson):
• Varn EC Wash
• Ultrachem Prima Wash
• Varn News 75 Wash
• printcom
®
wash 202B
• Sun Chemicals SUN WASH U H8830A
Note:
Test washes by rubbing a little on a plate to see if it removes the image.
Maintenance
• See the Epson Stylus Pro 7900/9900 Printer Guide for printer maintenance.
• Keep the PCU trays clean to retain their low-friction properties. Make sure the PCU is turned off.
Every week, wipe the trays with a paper towel moistened with a non-abrasive glass cleaner. You might
notice a light gray deposit of dust on the towel; this is normal. Do not spray glass cleaner directly on
the trays or the PCU.
