Measure Ink Coverage

[dean_gates@adobeforums.com]

I would like to know if Illustrator or Photoshop can calculate the amount
of ink coverage a particular image or letter will use as compared to another similar object and or letter

Dean,

You can use the info palette in Photoshop for that - just hover over the
area

In Illustrator the colour d/box will show you the ink-mix for any selected
object (of solid colour)

Thanks, Len

Let me re-ask this question a different way. If I have a white box and in the box wrote 1 2 3, in black, what would be the percent of black to the white background ? I trying to find the amount of coverage in a specific area.

Dean,

Histogram in Photoshop will give you a pixel count of your selected area. Selected pixels divided by total pixels will give you coverage ratio.

Hi

For my own understanding - could someone explain why you would want to know what the ink coverage is (not being condescending!)- does it have some impact on output or print quality?

Thanks

It impacts on your bottom line Lachet. Sometimes different methods may be cheaper, as they will use less ink. I use two spots on top of CMYK on my Roland and sometimes I can mix a colour more cheaply using them than I can if it were purely CMYK.

Thank You, Harron
I used your suggestion and found it to be way too easy !! Also, your response is basically the reason I needed to work this out. The difference in our ink cost will be approx. $6,800.00 over the length of the order.

Thank you,
