I struggled with the Graphtec barcodes in 19 also -- I even was on the phone with an engineer at SAI who agreed it was just pieced together at the last minute when Graphtec released their new lines. I still use 19 for barcode printing because when I upgraded to 21, it didn't work at all -- it couldn't find the file data (not sure if that's fixed now or not).
Anyway, I created a step-by-step to help others since I saw the question pop up quite often. Here you go:
In Flexi, select your image, and then click the Effects tab at the top, and select Contour Cut.
In Design Central, choose the type of contour (contour, rectangle, etc.) and the size (for contour, just enter the offset, for rectangle enter the size of the contour cut box).
Be sure to select the color (bottom left corner of Design Central) and choose CutContour for the kiss, or CutContour1 for the perf cut.
Be sure to click the green arrow or the settings won't take.
I set my contour (kiss) cut first, then repeat the steps to set the perf cut.
If you are using a CE7000 or FC9000, you can use the barcode feature.
Click an empty spot on the page, then go to Effects>Page Contour Cut Mark.
For most jobs, I select Graphtec 4 Points Type 2.
Then click Options in the lower left of Design Central.
You can leave the left half of the options page as it is.
On the right half, click Use Barcode, and select Roll Media as barcode Type.
I usually choose Long for Barcode Length.
Make a mental note (or write down) of the Barcode Link Info code (you'll want to make sure this code shows up in Production Manager later when checking your cut file details).
I usually set the Printer Margins to .5" for left & right (this keeps the barcode marks from making the print too wide for the media), then click OK.
Again, be sure to click the green arrow in Design Central for the settings to take.
You may have to adjust the size of your page and position of your graphics to fit with the barcode and registration marks.
I usually set my page to be about 3" larger than the height of my graphics.
Don't worry if your graphics extend beyond the registration marks side to side -- just be sure the marks clear the graphics (make the page taller if necessary).
Don't print from Flexi -- the registration marks will not scale properly. It's a known bug with Flexi and the barcode implementation.
Instead, export as a PDF, but when you export, make sure Selection Only and Suppress Options are both unchecked, then specify your filename and click Save.
The PDF Options page will open -- make sure all boxes are unchecked and click OK.
In Production Manager, click Add Job and select the PDF -- you should see it show up in the job details side of the page.
You can then open it and adjust your settings (I always make sure that it will print centered, and it will Hold when finished). When happy with the settings, send it.
As for the cut, in Flexi, select Cut Contour from the top toolbar (icon to the right of the Latex printer icon, it looks like a cutter blade sticking out of one of those pink erasers).
Adjust your settings and send it. One of the settings to make is on the Options tab (the tab with the cutter icon).
You'll see your two contour cuts. Make sure CutContour is at the top of the list, and if not hilight it and use the green up and down arrows along the right edge to move it up in the list.
Double click each CutContour and in the Before Job tab, use the dropdown to select #1 Plotter Condition for CutContour, and #3 Plotter Condition for CutContour1.
On my cutter, I have Condition 1 set for the kiss cut and Condition 3 set for the perf cut. But, I assigned Tool 3 (forward position) to Condition 1 also, so both contour and perf use the blade in the forward position. This makes it so I don't have to switch the tool position to go between contour and perf cutting.
Once it's in Production Manager, look at the file details side of the page (highlight the cut job and look at the right side of the screen). You should see the same Barcode Link Data code from when you created the page registration marks & barcode in Flexi).
The last thing you need to do in Production Manager is to enable the Data Link Barcode Server in the Setup menu at the top of the screen (make sure your cutter is selected in the main Production Manager screen -- I don't think the option will show up if a printer is selected).
