Adding a new line screen to Sierra
First, launch the Calibration Manager (located in the Xitron folder in your start menu).
Click on the Screen Sets option.
Next click on the Generate XQS screen set.
This will bring up a Generate XQS Screen Set window. You will have to enter some information:
Recorder type - Choose Tiff Export.
Resolution - Select the resolution needed for this device (dpi). This will be the output resolution of your platemaker.
Nominal ruling - Enter the line screen needed for this device (lpi).
Angle Family - Select the angle family needed.
Dot Shape - Select the dot shape needed (usually Euclidean).
For the Array size, leave this set to the Faster Rendering Times
Now, click on Generate to close this window, which will bring up a XQS Search Results. Look for the largest number in the Array Area column, select that option, then click on Install. Now click on Close.
Once you are done adding your screen sets, scroll through the list to find the one(s) you created, and double click on the screen set to bring up the comment window. Change the information to show the resolution/line screen and date created.
Now you have a screen set created, but you need to add the new screen set to an existing linearization (assuming you have plate linearizations).
Go back to the top of the Calibration Manager, and select the Recorders & Proofers icon.
In the window that opens TIFF Export should already be selected for the name, then click on Calibrate.
The Linearization options will appear. Verify that the resolution is correct, as well as the linearization is the correct one, then select Browse. This will open a new window showing all the screen sets.
Choose the screen set(s) that you just made (will match resolution, but line screens can vary), and click Add to Group.
This will verify that you are adding these screen sets to this linearization. Click on Yes to All.
Now you can see that there are additional screen sets in the bottom of this linearization group. Click close to this window.
If you have any press curves (characterizations), you may need to apply the new screen set to those as well. Launch the Sierra Client, and open the Admin options:
Select Press Profiles under the Admin Tasks, click on Default Press, choose your press, choose your desired media profile, and select Edit for the Press Media Profile.
Now, click on the Stretch & Characterization tab toward the top of the window.
In this tab you will be adding a screen set and press characterization. Select the screen(s) you want applied (your custom screens will usually be at the bottom of the list). Go to the bottom of the window, and select which press characterization you want, then click on Set.
Now you can click on OK to close this window. If you do not have an ICC profile, Characterization, or Screen set selected, it will not close this window. Once closed, it will bring you back to the Press Profiles window.
Now you can create/edit job templates for your new line screen, or change an existing job in the queue.
To use this new set, click on your job, then go to your plate settings. Select the Screening option, and turn on Override Screen Settings, then click on Browse to choose your new screen set.
In the window that pops up, scroll to the bottom to see all of your created screen sets. Choose the one you want , and click on OK.
You will see your ruling (line screen) change in the bottom of the window to match what the screen set values.
Click on your Press icon in your workflow, then click on the Media option. Verify that this is the correct Media Profile that has a characterization applied to the new screen set.
Now you can render your job with your newly created screen set.
