Yes. Printed out the job sheets which shows ink used for each of the last ten jobs by color (i think down to 1/100th of a ml), added all the colors up by job, calculated the square inches. Added 50 jobs together and then calculated the ink used to be about 1.46 ml/sq.ft.
This is great, as it comes very close to other calculations of about $.50 a square foot. I would be curious to know what media the calculation was based on. Another poster indicated a greater usage on Matte paper. As I mentioned earlier I will continue to check my usage from empty cart to empty cart to see what the total usage is including cleaning and nozzle checks.
As far as being a beginner, well I admit I am not a techie, but I have been as a working full time photograher for over 20 years now. ( No trust fund or rich wife or doting parents carrying my load either) I am opening myself to further criticism by some I am sure, but you can see my work and profile at www.jkwhitephoto.com
As far as a printing workflow goes.. I use Adobe RGB in PS then select that space also in the Print driver and select Let Printer Determine and select the correct paper type in the driver.
From Ian Lyons : Print Workflow 1
"The default configuration for the Print with Preview dialog is shown below as Figure 2. Notice that Color Handling is set to Let Printer Determine Colors. For the purpose of this tutorial we'll call this setting Print Workflow 1.
If you've just upgraded to Photoshop CS2 from an earlier version then Let Printer Determine Colors is the direct equivalent of Printer Color Management in Photoshop 7 and CS. Let Printer Determine Colors is probably the easiest and safest choice for new Photoshop users or those who are not yet familiar with how to integrate printer ICC media profiles into their workflow.
When you choose Let Printer Determine Colors you're in fact informing Photoshop that the document should be passed directly to printer driver complete with details of the ICC profile listed against Document. Photoshop will not make any adjustments to the document colours nor will it take any account of the media specified in your printer driver. By tagging the document with the ICC profile Photoshop is providing the printer driver with all the information required to ensure accurate colour rendering of the print. The document colour management is handled solely by the printer driver."
I will check the other method ..."Photoshop Determine Colors" to see if I get better results, but with lots of prints it is a bother to change especially when what you are doing produces good results.
Now I need to get back to my day job...as a photographer
