Hi

I've just found this forum and decided to join straight away as it seems like the best place for me right now.

I'm learning about colour management and I am trying to profile my large format solvent printer. It's a 1600mm CMYKx2 if that helps at all.

Does anyone have any experience using Versaworks and i1Profiler?

Basically, I am going to write my whole process down from start to finish, I've not managed to profile the printer yet as I'm unsure what to do/If I'm doing it right. I'm hoping you lovely people can look at my process and tell me what I'm doing right or wrong and help me get over the line.

1: Prepare Printer

    • Make sure all [Nozzles] are firing properly

    • Make sure [Bidirectional Printing Alignment] is adjusted correctly for the media

    • Make sure [Media Feed Calibration] is adjusted correctly for the media

    • Lower Print head (does this give a better print than the higher option???)


2: Prepare Versaworks

    • Correctly set the [Measurement Instrument] in preferences, choose Gretag Macbeth eye one for both selections (for i1pro2)

    • Configure Queue A settings. (Remember to put these back to normal once done)
       
        • Choose the [Layout] tab
            • Click [Get Media Width]
            • Change [Scaling] to 110% (i1Pro2 won't read it if printed at 100% i'm told)
            • Select [Mirror] if it’s necessary for the transfer process
       
        •  Choose the [Mark] tab
            • Under [Job Property Label] tick the following
                • Print Job properties
                • Quality Settings
                • Color Management
                • Device Controls
                • Date/Time

        •  Choose the [Printer Controls] tab
            • [Feed Calibration Controls] - User Printer Settings
            • [Other Controls] - Use Default Media Settings
            • [Heater Controls] - Use Custom Settings
                • Print Heater - 40ΊC
                • Dryer - 50ΊC


3: Create a [New Media Profile]

    • Go to Media / Media Explorer and [Create a New Media]

    • Choose a name and select a Template to match (i.e Generic Vinyl Dry, this does 10 passes as opposed to 8)

    • Select the new media and click [Print Quality Settings]
   
    • Go to [Calibration Settings] / Print Chart and make sure the limits are 100%, 100%, 100%, 100%

    • Click Print chart

    • Once printed on your required media, you'll need to measure the chart
   
    • Open I1 Profiler on the Mac
       
        • Under user mode select Select Advanced / Measure Chart
       
        • Choose 4 rows and 21 columns and choose Duel Scan

        • Calibrate the i1Pro2 and start measuring

        • Once done, double click a swatch and change CIE Lab to CIE Lch
       
        • Now start with Cyan and double click the far right swatch, it will now show you the Lch values (we want to find the highest C value which stands for Chroma)

        • Start double clicking each swatch from right to left and make a note of the one with the highest Chroma value
   
        • Do the same for all 4 colours

        • Once done, click save and save it to the desktop as a .cmxf file


4: Read the chart using Babelcolor Patchtool (Trial Version)

    • Open Babelcolor Patchtool

    • Open the file you’ve just saved and select the M1 measurement

    • Change the rows to 4

    • Now start with Cyan and select the patch that had the highest Chroma value and select it

    • Starting with the selected swatch hover over the patches from right to left and wait for the ΔE* (Delta E) value to be around 1 - 1.5 and take a look at the colours in the window to look at the colour change

    • As it stands, my current values for MD3 vinyl are
        • C: 60%
        • Y: 70%
        • M: 50%
        • K: 85%


5: Set ink limits in Versaworks

    • Open Versaworks and select Media Explorer
   
    • Select your new media and click [Print Quality Settings]

    • Now change the single colour ink limits to match your findings and re-print the chart

    • Once you've printed it, scan the patches in Versaworks then click on fine tune and apply once done

    • Take a look at the graphs and they should all have a nice smooth curve, adjust the nodes if any seem out of line. (I have attached my images)

    • We now need to find the total ink limit, select Total Ink limit > print chart and click print

    • Once printed, look at the chart and determine what the % value has the brightest colour without going dull and mark each row, my average appeared to be 190%

    • Once done, click the set ink limit and change it to match your finding i.e 190%
 

So far is this correct???


Now creating a profile chart to read is something else.

How many patches do I print?

Should I scramble them?

What shall I use for Patch Weighting?

Patchset Ink Limiting, this is set at 400% as default, should I match this to the 190% I've just set in Versaworks?

What is Linearization?
