Is the test to prove throughput or to prove that time between finish of Corel design and running the job is faster or what?
Part of the productivity process is contained within Corel itself , as the design of the graphic often has elements which have to work around laser issues or correspond to some machine property.
If a job is to be tested , it has to be from start of Corel design outwards.
I don't believe a test like this can actually show anything significant that would mean that one laser is better than another.
In terms of our Gcc's , well the time between finishing the graphic and getting it to print is a minute fraction of the total job time.
Thruput is dependant on a ton of things like how the graphic is optimised , the lasers optimisation routine and what is acceptable quality vs time taken. Speed or utility of a laser has also got to include downtimes , if your laser is blindingly fast and you are down for 2 days , vs a slighter slower one that's up , your thruput is shocking.
Another factor to consider is repeats , how quickly can you load and unload the machine and how quickly can you repeat the job , in my case repeating a job , considering the file etc is stored on the laser , is a simple button press. I also have my puter freed up after a print job is sent , in fact i dont even have to have the laser connected to a puter , we have a facility to store multiple jobs on the memory of my one set of lasers , switch it off and start running the same jobs the next day....sans puter.
Produtivity and thruput translate directly into money , as laser time is money assuming you are chock a block with work , anything that affects the generation of profits , like expensive repairs , dud jobs , laser tube replacements , waiting for tech support etc is relevant , not just how fast the machine performs. How do you factor in the fact Keith has to repeat jobs cos of letters middles falling out? Its double machine time , double material costs and a huge aggravation factor.
I have seen most of the lasers ppl own here in operation and have spoken to owners re their issues , it seems to me that what you lose on the swings you gain on the roundabouts and no mainstream machine in the power/price class is better than another.
As I say , I do not believe a simple head to head test proves much , one need to test over a longer time period with a multitude of jobs (most of us arent single task users , we are jobbing shops)
At any rate , the simple fact , proven time and time again , and re-itterated by experienced users is that the real determining factor of which machine to buy is the length and quality of it's warrantee and the accesibility of tech support and parts.
