One thing is to be said before we begin. Calibration is only required if you are going to print ScanTrust Codes, those WITH the Secure Graphic. It is not required if you are going to print regular ScanTrust codes, which we refer to as ScanTrust IDs or SID codes.
For the sake of this article, we assume that you have printed your proofsheet already.
To proceed, you will need to perform the calibration scans.
- open the STE App
- log in (your user role should be either printer operator or printer administrator)
- NOTE: Without either of these, you cannot log into the Scantrust enterprise printing module
- if you are not already in the calibration screen, click on the hamburger button in the top left corner
- from the slideout menu select 'calibration'
The app itself will also guide you through the process calibration process, but we will describe it in detail here as well.
- click on 'scan' at the bottom right corner of the screen
- you may now click any code from the proofsheet and the app will then know which proofsheet you scanned
If you scanned a substrate specific proofsheet you will automatically skip the next step of having to select a substrate. The app will know already which one it is.
If you scanned a general proofsheet you will have to tell the app on which of the previously to this equipment associated proofsheets you have printed this time.
- all associated proofsheets will show up on screen
- find the correct one
- underneath the substrate name, it says that this substrate has never been calibrated for this specific printer in the past. (If you come across a substrate that has already been calibrated you have 2 options: you can abort, or recalibrate. To recalibrate, just keep going.)
- click on the correct substrate
- Now you see the name of the printing equipment and the name of the substrate.
- double check that what you selected is correct
- if you notice that you selected the wrong substrate, click on the back error at the top left corner of the screen to select the correct one
- if you believe the substrate was printed on a different printer, you will have to start over because proofsheets are always specific for the printing equipment.
- it is not permitted to print a proofsheet generated for one piece of equipment on another
- when you are certain all is correct, click 'next' at the bottom right of the screen
You should now see all the codes on the screen outlined symbolically, just like they are outlined on the actual printed proofsheet. They are also numbered just like the codes on the proofsheet are.
- click on 'scan' in the bottom right corner of the screen to begin
- the scan screen will open
- place the code inside the scan window on screen. The corners of the code should be aligned with the blue corners inside the scan window
- as soon as the app captures an image of the code, it will go into analyzing mode (This should take no more than a couple of seconds)
- if everything is okay, the app will let you know that the code was read successfully
- the app will now let you know which code to scan next
- should you accidentally scan a different code from the one the app told you to scan, there is no problem
- the codes you have scanned already, are colored purple on your screen proofsheet overview
- the app will always just suggest you the next code until each of the codes on the sheet is scanned once.
- once each of the codes on the sheet has been scanned, the app will let you know. Then simply click 'okay'
You will now see the proofsheet overview again. Notice, earlier all of them were grey, now they are colored light purple.
- click on 'submit' in the lower right-hand corner of the screen
Now the calibration session has been submitted to our engineers, who will evaluate your scans and determine which code-type best suits your printer-substrate combination.
In the portal, under -> equipment -> calibration session history all the calibration session will show up with status submitted until our engineers performed the evaluation. Please be patient as this may take a couple of days. (Reach out to email@example.com, should the calibration be required for an urgent client contract.)
Once our engineers evaluated your submitted scans and all okay they will approve the calibration. you will receive a notification email as soon as your calibration has been accepted and the status of the calibration session in portal is set to accepted. Your printing equipment is set to active, meaning it can now be used to print proper workorders.
IMPORTANT It is important to note that any printer, can only print workorders for an already calibrated substrate! However, there is no limit as to how many different substrates can be calibrated for one printer.
NOTE: General Proofsheet vs Substrate Specific Proofsheet
The difference between a general proofsheet and a substrate specific proofsheet is that on the substrate specific proofsheet the name of the substrate is already written on the proofsheet and it may only be printed on that substrate. On the general proofsheet there is no substrate reference. It simply says: ANY.
General Proofsheets are beneficial for i.e. offset or flexo printers when you wish to calibrate for multiple substrates. We recommend that you note down the name of the substrate that you printed on. Preferably in such a way that you can easily find it in portal again.
