Description

This KB contains instructions about how to evaluate and install generic Esko EPL files.

What are generic Esko EPL files?

Generic Esko EPL files are customized with R&D tools and result in a better proof (due to the more uniform color space) compared to an EPL created either by EFI or manually. The use of these EPL files is mandatory in order to make a color accurate contract proof with Pack Proof!

Procedure

This procedure exist out of two parts, an installation part and evaluation part.

(star) Do a repair of the Esko Profiles installer from the IEP DVD and select the Epson model for which you want to install EPL files.

  1. Mount the IEP DVD.
  2. Select the Software Installation menu (located to the left).
  3. Scroll down to the bottom of the page and click Repair the Proof Server Profiles component.
  4. Select the Modify option in the Esko Profiles installer.
  5. Click Next and select the model for which you want to have EPL files available.

EPL files installed via the Esko Profiles installer will appear automatically in the Proof Client. However, if they do not appear, a restart of the proof server might be required (right click the green square icon in the system tray and choose for Restart Esko Proof Server in the contextual menu).

Follow these steps if you downloaded a zip file from this page:

  • Unzip the archive.
  • Open the proof client.
  • Switch to the System Manager view.
  • Go to Tools > Esko Proof Uploader menu (or press F7).
  • Click the Media Profiles tab.
  • Click the Choose button next to the Printer Linearization (EPL) field.
  • Browse to the unzipped archive and select all the EPL files.
  • Click the Open button.
  • Click the Upload button.

Now create a new output device (if not available) and follow these steps:

  • Click the Device pane and select the HT driver for the available Epson model.
  • Fill in the IP address.
  • Click the Media pane and select the correct ink type.
  • Select the correct media name.
    • v14 EPL files start with the prefix "v14".
    • v16 EPL files use as media name "Esko Generic Media v16".
  • Select a Normal-TAC or if available High-TAC EPL.
  • Save the output device.

Use the following workflow settings in case you want to achieve higher print speeds:

  • Select the workflow.
  • Click the Workflow pane.
  • Tick the checkbox in front of the Print bi-directional option.


The bi-directional option increases the likelihood of print head alignment related issues. These include banding and in consequence sometimes also decreased color accuracy. With the print-head alignment procedure this can be compensated and corrected.

Evaluation step

Please download one of the following PDFs. These provide the necessary fields and elements for the evaluation of the EPL applicability:

For the EPSON SC-P50x0 / SC-P70x0 / SC-P90x0 devices with HDX Violet (CMYK-OGV) inkset:

For the EPSON x900, WT7900 and SC-P50x0 / SC-P70x0 / SC-P90x0 devices with HDX (CMYK-OG) inkset:

Overinking

For the evaluation of this chart set the drying time of your output device to 0 minutes to be able to inspect the printout immediately after printing.

Upload this PDF in the Job Explorer panel (drag and drop after selecting the correct workflow or press Ctrl+O)

Inspect the page immediately after printing. In case you see the effect of overinking pictured on the below examples, you might need to try to use an EPL designated for lower quality paper (Normal-TAC or Low-TAC) or install a better quality paper and restart the evaluation process.

Overinking examples:

Banding

To the left and right a gray object is printed to evaluate and detect banding. Consult the printer documentation and search for the procedure to perform a print head alignment when banding is detected.

  1. Please state that you need to select Esko Generic Media v16 in the Media window for the installed Esko EPLs to be visible. This has fooled some customers.
