Mail Merge Numbering for Slitter Style Devices

Greetz everyone! Was wondering if I could pick your brain and learn a better way to do things.

We often use InDesign to mail merge numbered documents, easy peasy when they're just standard prints. However, we also do a fair number of jobs that are numbered cards of some kind. For these jobs, much like business cards, we've been attempting to optimize and automate our workflows using our Duplo 618 Slitter Cutter Creaser.

However when things are numbered, this creates an issue - the output stacks are all out of order. I have attached a graphic to demonstrate what I mean.

In the above graphic, you can see my print file - these cards are set 18up on a 12"x18" canvas. They are numbered using an excel list that looks like this. If we cut these on a guillotine, the order of the numbers is fine. But if we run them through the slitter, we get the ordering problem. The sitter puts the second row on top of the first row, so first the 3 numbers highlighted in yellow, then the three numbers highlighted in green, then the three numbers highlighted in blue, etc.

It makes sense that they are out of order because the way they're being trimmed is drastically different. What I'm wondering is what methods ya'll are using to create ordered/numbered prints that will be in order once cut through a slitter. Or do you just run all types of jobs like this through a guillotine instead?

You need an imposition program such as Montax Imposer. ID mail merge is very limiting for this type of imposition.
 
If you really want to get this done in InDesign, there are ways to do it without even using the Mail merge feature. You can use a combination of Paragraph Stymes/Object Styles, numbering and list options to have numbers automatically generated.

You could place some frame on the master spreads and override them, once all artworks have been placed. Have a look at the attached document for reference.
Yet one could wonder why do you want to impose in InDesign. You would indeed probably prefer using a dedicated solution for that.

There are some solutions at Enfocus that you may want to look at:

You could do this in Quite Imposing but it’s a multi-step process and a bit of a pain, I believe they’re working on a new version that could automate it more. Best solution is Montax Imposer it has a built-in feature for imposing for these auto cutters and the price is very affordable.
 
I will second @GVG's suggestion for Montax Imposer. You get a lot of functionality (including variable data and hot folder support) for a very affordable price. I also have a Duplo and had to setup a Montax imposition specifically for it.

Best regards,

I'm using InDesign because I generally have had no issues with it since all I've had is a guillotine cutter until recently, and the vast majority of our files are set up in INDD. I will definitely look into these suggestions! One small caveat is we are primarily mac based so Windows-only solutions will be a no go for us, for the most part.

You could install a virtualization software like VMware, Parallels, VirtualBox, or UTM and install a Windows guest OS.
 
can't you just re-arrange you excel file to match the output I'm sure there's a logical pattern
Certainly could, I was kind of hoping someone here had a magic excel formula I could adapt lol. Doing it by hand would be a nightmare. Hopefully these imposition tools can help. I already have quite imposing so I'm looking into how to accomplish that way, hopefully without breaking our existing workflows too much
 
Do you have a fiery impose license? If so just output these as straight cards out of indesign. IE for 1000 single-sided cards.
  • Indesign Document setup as 2.5in x 3.5in (two pages if you need double-sided - front and back).
  • Mail Merge csv file is setup numbered from 1000 to 0001 (reverse order)
    • Technically you could use your existing workflow just run the numbers in reverse order with the idea that they're gonna come off the short edge.
  • Final PDF file is a 1000 pdf page file with numbers 1000 to 0001
  • Use fiery impose to position all the cards using the duplo short edge option. Since the cards are in reverse order they'll come off the duplo with 1000 on the bottom of the stack and number 1 ending up on the top (I assume you could do the same thing in some other non-fiery imposition software)

Hi - here is an option or two.

I use a number list generator that can skip / jump per list.
Six spots on the sheet? Six lists, total divided by six, make six "page areas" w/ six merge boxes. Away you go!
Cut and stack. :)
or
As I have posted before: Imposition Studio has "Variable Data Printing And Numbering" which does mostly the same thing more easily.
YMMV.
