Keeping up to date – how the car analogy may no longer be relevant in the printing world

In his latest blog post, Martin Bailey, consultant at Global Graphics Software, takes a look at some of the reasons why his go-to car analogy to help his audience understand the world of print may no longer be as relevant as it once was:

Over the years I’ve used analogies in many of my blog posts, conference presentations and white papers; they’re a very effective way of sharing a high-level understanding of sometimes complex ideas. I’m not a car fanatic, so I’ve not had any specific motivation to compare print technologies to anything around cars, but for some reason it seems that car analogies have consistently just worked, so I’ve used them.

But I realized recently that I’m going to have to rework some of them in response to the growth of electric vehicles replacing internal combustion. I know that growth is very uneven across the world (wow, go Norway!), but it’s clearly the future of motoring for many of us. Much of what I write and report might be summarized as “this is the future and how we’ll get there”, so building on something that will become more and more outdated for many readers and listeners introduces an unwelcome distraction from the analogy. It also makes it less effective because analogies must be based on a common understanding or experience, otherwise they just don’t work.

On the other hand, internal combustion vehicles are not even close to the point yet where all readers and listeners will regard them as dinosaurs of historical interest only. So I can’t sensibly use them as a representation of what we were all doing in the past.

So, I thought I’d look through some of the car-based analogies I’ve used to see which need updating, and which are fine as they are:

I’ve often compared a digital press and its associated digital front end (DFE) to the components of a car:

  • The supplied job file, probably in PDF, is the fuel
  • The steering wheel and dashboard are the DFE control systems and user interface
  • The engine is the RIP (clearly the most important part of the entire system, but then I may be biased!)
  • The gearbox and transmission are the electronics and drivers, like those from our friends at Meteor inkjet
  • The wheels are the inkjet heads, actually putting the rubber/ink on the road/substrate

Well, some of those parts still make sense, but I’m not sure that I can equate submitting a PDF file to charging a battery. Somehow the motors in an electric vehicle never seem to have the prominence that I’d personally give to a RIP. And the motors are often linked direct to the wheels, with less of the gearbox and transmission infrastructure than you’d use for internal combustion. This one needs some serious fixing.

Next up is a statement that we used, for example, in Full Speed Ahead: how to make variable data PDF files that won’t slow your digital press: that making a PDF file constructed for efficiency is like using better fuel in a car. There can be a clear step-up from regular to super for gasoline/petrol, but electricity is electricity, at least once it’s in the car battery.

I guess you could argue that charging points with different power capabilities, from 7kW up to 350kW, will significantly affect how long it will take to recharge the car, and therefore on how far you can get in a day, but it’s not really the same discussion. That’s another analogy that I’m going to have to work on.

And finally, for now, I’ve described companies who build digital presses without thinking about software to process job files and proper user interfaces as being like people thinking they can sell rolling chassis: cars with no bodywork, no seats and not even a cup-holder. You may get a few sales for that in specialist markets, but it’s not exactly a mass market.

Of the three analogies I’ve listed here, I think this is the only one that might survive unscathed, although it probably has less value without being able to equate the other bits of the car to digital press and DFE components.

As I said to start with, I had no reason to pick cars as the base for analogies that I use other than that they seemed to work well. I have a feeling that may not be as true in the future. I guess there did have to be one advantage to big oil!
