4. Are the plates anodized?
Epson DirectPlate Aluminum is an anodized and specially coated press plate.
5. Are these plates light sensitive?
No, these plates are NOT light sensitive
6. Do these plates have grain?
No, they are considered smooth plates. Note that spite of this, they may require more water for usage
(see press operation recommendations) and a longer warm up cycle.
7. Can I cut/ convert these plates?

cause damage to the printer due to a sharp or jagged edge
.
8. What is the shelf life of the Epson DirectPlate Aluminum plates?
Because these plates are not light sensitive, there is not a strict shelf life for these plates. However,
Epson recommends no longer that 2 years as a shelf life for these plates.
9. Can I reuse plates after they have been used on press?
Yes. Simply take the plate off and clean it using a recommended cleaner and fountain solution.
10. Can I use a deletion pen?
Yes. You can delete images with IWATSU Elotax Corrector OX-1. You can also use AGFA Lithostar
Copyrapid Correction Pen. A standard pencil eraser works well to delete a small section from an image.
11. Are these plates made by Epson?
Yes, these are unique plates that are specific to the Epson Stylus Pro 7900 CTP system
12. How many impressions can I get out of a plate?
The number of impressions is largely dependent on the condition of your press, the press pressures, the
plate, the usage of the plate, and the image you are printing. During normal usage with correctly set
press pressures we estimate that you will get between 15,000 and 20,000 impressions. However,
excessive plate pressures, excessive plate cleaning with non-recommended plate cleaners, or unsuitable
fountain solutions can contribute to lower than expected run lengths.
13. What if I have a plate with a bent corner, Can I use that?
No. It is highly likely that a plate with bent corners will damage the print head on the Epson Stylus Pro
7900CTP Printer. You should inspect all plates prior to loading them to assure that they don’t have any
bent corners. Epson’s packaging prevents bent corners. If you receive a package that is damaged, contact
your Authorized Reseller.
14. Are these plates dry when they come out of the Epson printer?
Yes. They are dry to the touch. However, you must cure them in the PCU prior to mounting on press.
This is necessary because of a chemical reaction that occurs between the plate coating and the Epson
UltraChrome HDR ink which hardens the ink allowing it to last the duration of the print run.
