Pdf ink coverage

This can be found in the Print Production tools. You specify a threshold value and any area within the PDF that exceeds this value is highlighted. The cursor is positioned in the lower-left corner of the statue with Acrobat showing the ink coverage for that spot.

Similar functions are offered by several prepress systems, which can check complete press sheets for any TIC-related issues. There are preflight tools like Enfocus Pitstop that can check total ink coverage.

To discuss TIC, check this thread on the B4print forums. PitStop Pro most certainly checks ink density in images. You can specify the area of calculation for averaging. FlightCheck Pro can report the ink density but it streams each individual pixel with no ability to average. But in order to truely calculate the ink density and take into consideration stacking order and over prints you have to have a RIP to perform that function.

In English: only what I wrote here or what others have copied from my answers. The spring edition from has a longer article by me I conclude that inkcov has no configuration options? Potential params to tweak in my next comment: — Kurt Pfeifle.

But if you do not know what you do, better don't touch it for serious results! Show 3 more comments. EDIT: 1. Existing tool Searching the web, I found a tool that performs exactly the same, providing also support for many formats doc,odt,ps,png,pdf etc. If you want to calculate the ink coverage for the whole file rather than for each page separately, you can do it with awk : pkpgcounter --colorspace BW -r file. Custom solution I don't know of such a tool, but it would not be difficult to approximate the percentage of black in a PDF file, using Linux command-line tools.

I drafted a script which may be useful:! For this to work, you will need the aforementioned tools, which will be probably already installed in your system Otherwise, both xpdf and convert will be available in the repo of your distribution How it works: It converts the pdf file to a series of monochrome png images one image for each page.

If you choose the wrong ICC profile, you will not get the exact values about your ink coverage but even then it should give you a close estimate. Now your PDF is open in form of a pixel file. You then go to the filter menu and start the filter Average Blur or Blur Average , i do not remember the exact name.

The result is one color that fills your whole image. This color represents the average color of the whole image. Now you go to Photoshops window menu and open up the info panel. There is also an option to get the total ink coverage in the info panel. That's it, i hope this can help! This whole procedure can, of course, be made more convenient when you make a Photoshop action out of it and put it into a droplet. Unfortunately, color management is a complicated matter and cannot be explained in one single post.

Maybe, some day, cars will be able to fly to the moon but there will never, ever be a scanner or a camera that directly catches pictures in CMYK mode. The complicated thing is that there are several different ICC color profiles for different kinds of paper. This is a necessity because there are different kinds of paper whith different paper tones, different dot gains and of course different amounts of total ink coverage they can hold. It can be done in Photoshop, then you have a technique which is called Early Binding.

It can be done while the PDF file is exported, then you have a technique called Intermediate Binding. It can also be done by the print shops prepress in the PDF file, this technique is called Late Binding. But also, there are also lot of things that can go wrong and mess up the whole job. I would strongly recommend to invest some time and money in literature and training courses about this sensible topic. A doctor should not learn how to do heart surgery on the internet and a press operator should not learn how to set up his color management, online, either.
