Hello Bloodsaler, There were never any official densities in reference to SWOP, but the ones that Gordon has listed are the most commonly accepted values. Since ISO in 2004 Industry Standards have used L*a*b* for the Target Values of Ink Colors because of the fact that density values can vary...

Great Analogy, but still missing the Mark Great Analogy, but still missing the Mark For example: a fixed-size 3D depiction of a profile = Gamut magical toy bricks that could turn to any color = Gamut Volume Bit Depth does not equate to how many colors can be reproduced, but how many steps...

Bit Depth has nothing to do with the Box of Crayons Bit Depth has nothing to do with the Box of Crayons Hello MrRWright, Per my previous post, The Crayon Box is the Gamut & and the number of Crayons in the Box is the Gamut Volume. The bit Depth would be the list of contents printed on the...

The Volume of a Bit and the Depth of a Gamut The Volume of a Bit and the Depth of a Gamut Interesting Subject and I can never resist trying to visualize these concepts so that I better understand them. There are a few concepts explained in the post that are very good, so I thought I would try...

Hi Mike, Sorry for the confusion - I don't know how to say it clearer. Here is what I stated earlier: Calibration Curves should compensate for Tonality and Gray Balance in my opinion. The calibration curve adjusts for Gray but is short of Gray Compensation which is done via some form of...

Hi Prepress Guru, I feel your pain! That is the line being sold to the designers and print buyers. Have your printer (Epson, Canon, etc.) G7 Certified and then the Pressroom can match it if they are G7. I recently helped a printer with their calibration to G7 and if I heard once from the Head...

Gray Compensation in the Color Bar Gray Compensation in the Color Bar Hi Mike, First and foremost I never recommended using "Uncompensated" Color Bars. Color Bars should have whatever CALIBRATION Curve that you are using applied to it. They should also use the same screening parameters that...

Joe, Thanks - Chuck

Heidelberg CAN Heidelberg CAN By the way, in response to the original post by prepressguru: This illustrates my point exactly: Service group enters Heidelberg Printer after Heidelberg has set them up to G7 using Heidelberg Solutions. Service group repeats very similar procedure and ends...

This is exactly what I am talking about. There is a fundamental misconception about press control using gray balance and print monitoring with gray balance. Color Bars are for controlling the ink keys and if there are patches left over we can extract data from them as well. Color Bars on the...

Perhaps we should change Python Movies? Life of Brian may be more appropriate to this theme: Throng chasing Brian: Look he's dropped his Sandal (Gray Balance) folow the Sandal! Look, he's dropped his Gourde (Device Link) follow the Gourde! Oh Brian did you drop your Gray Balance as a sign...

Sham Wipers and other thoughts Sham Wipers and other thoughts Hi Mike (Eddington), I just knew I was going to strike a nerve. Sorry - not my intention and there was nothing aimed at you at all - just wanted to entertain myself while writing my post. That is the problem with these forums...

Gray Balance Optimizer Gray Balance Optimizer Hello TRoy, Heidelberg's First Response Unit here with some more Sham-Wow Magic Dust! But seriously now. Your original post asked a lot of questions and opened up what could be a never ending discussion filled with differing opinions and possible...

Hello T-Roy, Heidelberg workflow is extremely easy to apply color management. There are sections for the profiles in Printready and it can take regular profiles or device links. As to your desire to calibrate and profile 4 different substrates with GCR Settings for Ink Savings this is easy as...

Heidelberg Color Bars (Dipco 3) and Image Control Heidelberg Color Bars (Dipco 3) and Image Control Hello Karl, What problems are you having? There should be no issues with the bars when properly placed and formatted. You can feel free to contact me directly if you want to. Chuck Koehler...

Hello Eduardo, Jobs that are stored on Image Control are just the job settings like the color bar that was used, changes to reference values like +/- ink percentages, multi-color reference values from inside the job, or image areas used in the job. Also, if the job was saved as an OK sheet...
